d7901 | train | You can simply loop over the related Document objects from the Event object itself by using document_set (the default related_name for Document i.e. the model name in lowercase with _set appended). Also you can optimise the number of queries made by using prefetch_related [Django docs]:
In your view:
@login_required
def consultant_home(request):
consultant_pr = Consultant_Profile.objects.get(user_id=request.user)
events = Event.objects.filter(consultant_id=consultant_pr.pk).prefetch_related('document_set')
context = {'events': event, 'consultant_pr': consultant_pr}
return render(request, 'Consultant/consultant_documents.html', context)
In your template:
{% for event in events %}
<p>Event id: {{ event.event_id }}</p>
{% for document in event.document_set.all %}
<p>document name: {{ document.document_name }}</p>
<!-- Use document.path.url instead of manually rendering its url -->
<p>path: <a href="{{ document.path.url }}">{{ document.path }} </a></p>
{% endfor%}

d7902 | train | Universal answer (with explanation):
BeginInvoke is function that send a message 'this function should be executed in different thread' and then directly leaves to continue execution in current thread.
The function is executed at a later time, when the target thread has 'free time' (messages posted before are processed).
When you need the result of the function, use Invoke. The Invoke function is 'slower', or better to say it blocks current thread until the executed function finishes. (I newer really tested this in C#, but it s possible, that the Invoke function is prioritized; e.g. when you call BeginInvoke and directly after it Invoke to the same thread, the function from Invoke will probably be executed before the function from BeginInvoke.)
Use this alternative when you need the function to be executed before the next instruction are processed (when you need the result of the invoked function).
Simple (tl;dr): When you need to need to only set a value (e.g. set text of edit box), use BeginInvoke, but when you need a result (e.g. get text from edit box) use always Invoke.
In your case you need the result (bitmap to be drawn) therefore you need to wait for the function to end. (There are also other possible options, but in this case the simple way is the better way.) | unknown | |
d7903 | train | Can I easily build a JSON-RPC consumer
in .NET?
Yes. JSON-RPC services are simple to consume as long as you have a robust JSON parser or formatter. Jayrock provides a simple client implementation JsonRpcClicnet that you can use to build a consumer. There is also a small demo sample included.
Are JSON-RPC web services self
documenting and discoverable, like a
SOAP WSDL?
No, there is nothing standardized but there are ideas being floated around like Service Mapping Description Proposal.
Can I easily add a Web Reference in
Visual Studio to a JSON-RPC web
service?
This can work if the server-side implementation provides a WSDL-based description of the JSON-RPC service but none are known to provide this to date.
A: Check out Jayrock.
Jayrock is a modest and an open source
(LGPL) implementation of JSON and
JSON-RPC for the Microsoft .NET
Framework, including ASP.NET. What can
you do with Jayrock? In a few words,
Jayrock allows clients, typically
JavaScript in web pages, to be able to
call into server-side methods using
JSON as the wire format and JSON-RPC
as the procedure invocation protocol.
The methods can be called
synchronously or asynchronously.
A:
Can I easily build a JSON-RPC consumer in .NET?
Shouldn't be difficult as long as you know what you're doing.
Are JSON-RPC web services self documenting and discoverable, like a SOAP WSDL?
Discoverable yes, documenting in as much as you can get function names and parameter lists. (not entirely sure what you're asking for as far as documentation goes).
Can I easily add a Web Reference in Visual Studio to a JSON-RPC web service?
I don't think so, no. (Though, I have no idea, it's possible. My experience with JSON-RPC is in PHP/JS mostly)

d7906 | train | To pass data when you submit a form, you have to include that data in a form input field (hidden, visible, doesn't matter).
A: You can add hidden fields in your HTML form like this
<input type="hidden" id="Data_ID">
<input type="hidden" id="Data_Type">
and then set the values in your javascript function and then submit (?)
<script type="text/javascript">

d7907 | train | Let's say I have 32-bit ARGB value with 8-bits per channel. I want to replace the alpha component with another alpha value, such as 0x45
unsigned long alpha = 0x45
unsigned long pixel = 0x12345678;
pixel = ((pixel & 0x00FFFFFF) | (alpha << 24));
The mask turns the top 8 bits to 0, where the old alpha value was. The alpha value is shifted up to the final bit positions it will take, then it is OR-ed into the masked pixel value. The final result is 0x45345678 which is stored into pixel.
A: Bitmasks are used when you want to encode multiple layers of information in a single number.
So (assuming unix file permissions) if you want to store 3 levels of access restriction (read, write, execute) you could check for each level by checking the corresponding bit.
rwx
---
110
110 in base 2 translates to 6 in base 10.
So you can easily check if someone is allowed to e.g. read the file by and'ing the permission field with the wanted permission.
Pseudocode:
PERM_READ = 4
PERM_WRITE = 2
PERM_EXEC = 1
user_permissions = 6
if ((user_permissions & PERM_READ) == PERM_READ) then
// this will be reached, as 6 & 4 is true
fi
You need a working understanding of binary representation of numbers and logical operators to understand bit fields.
A: Bit masking is "useful" to use when you want to store (and subsequently extract) different data within a single data value.
An example application I've used before is imagine you were storing colour RGB values in a 16 bit value. So something that looks like this:
RRRR RGGG GGGB BBBB
You could then use bit masking to retrieve the colour components as follows:
const unsigned short redMask = 0xF800;
const unsigned short greenMask = 0x07E0;
const unsigned short blueMask = 0x001F;
unsigned short lightGray = 0x7BEF;
unsigned short redComponent = (lightGray & redMask) >> 11;
unsigned short greenComponent = (lightGray & greenMask) >> 5;
unsigned short blueComponent = (lightGray & blueMask);
A: Briefly, a bitmask helps to manipulate the position of multiple values. There is a good example here;
Bitflags are a method of storing multiple values, which are not mutually exclusive, in one variable. You've probably seen them before. Each flag is a bit position which can be set on or off. You then have a bunch of bitmasks #defined for each bit position so you can easily manipulate it:
#define LOG_ERRORS 1 // 2^0, bit 0
#define LOG_WARNINGS 2 // 2^1, bit 1
#define LOG_NOTICES 4 // 2^2, bit 2
#define LOG_INCOMING 8 // 2^3, bit 3
#define LOG_OUTGOING 16 // 2^4, bit 4
#define LOG_LOOPBACK 32 // and so on...
// Only 6 flags/bits used, so a char is fine
unsigned char flags;
// Initialising the flags,
// Note that assigning a value will clobber any other flags, so you
// it should generally only use the = operator when initialising variables.
flags = LOG_ERRORS;
// Sets to 1 i.e. bit 0
// Initialising to multiple values with OR (|)
flags = LOG_ERRORS | LOG_WARNINGS | LOG_INCOMING;
// sets to 1 + 2 + 8 i.e. bits 0, 1 and 3
// Setting one flag on, leaving the rest untouched
// OR bitmask with the current value
flags |= LOG_INCOMING;
// Testing for a flag
// AND with the bitmask before testing with ==
if ((flags & LOG_WARNINGS) == LOG_WARNINGS)
...
// Testing for multiple flags
// As above, OR the bitmasks
if ((flags & (LOG_INCOMING | LOG_OUTGOING))
== (LOG_INCOMING | LOG_OUTGOING))
...
// Removing a flag, leaving the rest untouched
// AND with the inverse (NOT) of the bitmask
flags &= ~LOG_OUTGOING;
// Toggling a flag, leaving the rest untouched
flags ^= LOG_LOOPBACK;
**
WARNING: DO NOT use the equality operator (i.e. bitflags == bitmask)
for testing if a flag is set - that expression will only be true if
that flag is set and all others are unset. To test for a single flag
you need to use & and == :
**
if (flags == LOG_WARNINGS) //DON'T DO THIS
...
if ((flags & LOG_WARNINGS) == LOG_WARNINGS) // The right way
...
if ((flags & (LOG_INCOMING | LOG_OUTGOING)) // Test for multiple flags set
== (LOG_INCOMING | LOG_OUTGOING))
...

d7909 | train | It's pretty easy to remove continue from the loop. What you need is two indexes in your loop. One for the position in the source array and one for the position in the array to copy to. Then you put the copy operation inside the if statement so if there is no copy you do nothing to go to the next iteration. That would make you loop look like
for (int source_index = 0, copy_index = 0; source_index < n; ++source_index) { // increment source_index always
if (!strchr(vowels,s[i])) {
// this isn't a vowel so copy and increment copy_index
afterElimination[copy_index++] = s[i];
}
// now this is the continue but we don't need to say it
}
A: This is a typical approach to filtering letters from a given string.
#include <string.h>
char s[20] = "something";
char no_vowels[20] = {0};
int i = 0;
int j = 0;
const char *vowels = "aeiou";
while (s[i]) {
if (!strchr(vowels, s[i])) {
no_vowels[j] = s[i];
j++;

i++;

d7912 | train | Rather than using the lock() keywords I'd suggested seeing if you can use the Interlocked class which is designed for small operations. It's got much less overhead than lock, in fact can be down to a single CPU instruction on some CPUs.
There are a couple of methods of interest for you, Exchange and Read, both of which are thread safe.
A: You want to look into the Lock keyword. Also you might want to this tutorial to Threading in C#.
A: As Filip said, lock is useful here.
Not only should you lock on provider.SetNumber(currentNumber), you also need to lock on any conditional that the setter depends on.
lock(someObject)
{
if(provider.CanPassNumber(false, currentNumber))
{
currentNumber++;
provider.SetNumber(currentNumber);
}
}
as well as
if(condition)
{
lock(someObject)
{
provider.SetNumber(numberToSet);
}
}
If condition is reliant on numberToSet, you should take the lock statement around the whole block. Also note that someObject must be the same object.
A: You can use the lock statement, to enter a critical section with mutual exclusion. The lock will use the object's reference to differentiate one critical section from another, you must have the same reference for all your lock if it accesses to the same elements.
// Define an object which can be locked in your class.
object locker = new object();
// Add around your critical sections the following :
lock (locker) { /* ... */ }
That will change your code to :
int currentNumber = provider.GetCurrentNumber();
lock (locker)
{
if(provider.CanPassNumber(false, currentNumber))
{
currentNumber++;
provider.SetNumber(currentNumber);
}
}
And :
if(condition)
{
lock (locker)
{
provider.SetNumber(numberToSet);
}
}
A: Well first of im not so good with threading but a critical section is a part of your code that can only be accessed my one thread at a time not the other way around..
To create a critical section is easy
Lock(this)
{
//Only one thread can run this at a time
}
note: that this should be replaced with some internal object...
A: In your SetNumber method you can simply use a lock statement:
public class MyProvider {
object numberLock = new object();
...
public void SetNumber(int num) {
lock(numberLock) {
// Do Stuff
}
}
}
Also, note that in your example currentNumber is a primitive (int), which means that variable's value won't be overwritten should your provider's actual data member's value change. | unknown | |
d7913 | train | Space complexity: Identify data that occurs "in large quantities" or "repeatedly". Assign numbers to these quantities, e.g., N = number of lines in a file, or M = number of elements in an array. Add these quantities. Watch out for the dynamic creation of data structures: if you have an array of N numbers and another one of M numbers and you create a table of all the products, then the space complexity of the table is...
Time complexity: Identify repeated actions. Some may be hidden (as in Perl), some are explicit, e.g. in a for loop. Use the results of space complexity to quantify these repetititions. A loop may be terminated early: then you must estimate the average time of execution. Loops occurring one after the other add up. If you know that a loop body is executed N times and this body contains an inner loop that executes M times, then the body of that inner loop is executed - how often?
Very frequently it's just a simple exercise of counting, bookkeeping and simple arithmetic, although there are several examples where a good answer requires heavy math.

If not found there, read from the sample/default file in the jar file. After updating content in memory, save to external location, where it will be read from on next execution.
A: You can make use of Classloader to read the file present in jar, but ofcourse you will not be able to write to it.
To be able to read and write both file should be present in filesystem, you may want to have a look at Read and Write to Java file via Resource | unknown | |
d7926 | train | This reason that this hasn't been answered is because you're actually asking for quite a lot of work to be done to make this happen.
In essence, you're looking to pass data from your table into a modal dialog <div class="dialog" id="loslegen-dialog">. Most likely onclick.
There are many ways to do this, the way I would personally do it would be to use the dialogOeffnen function which causes the dialog (popup) to open.
Create span elements around the data you want to use in your dialog i.e.
<td>
<span id="id_element"><?php echo $row["ID"];?></span><br>
</td>
and
<td>
<span id="title_element"><?php echo $row["Titel"];?></span><br>
</td>
Then ensure you have elements with specific ID attributes where you'd like to display this data i.e.
<h1 id="dialog_title"><?php //echo $row["Titel"]; //You can remove this ?></h1>
Then inside dialogOeffnen before you display the modal/popup:
document.getElementById("dialog_title").innerText = document.getElementById("title_element").innerText; | unknown | |

d7931 | train | The getchar behavior
For linux the EOF char is written with ctrl + d, while on Windows it is written by the console when you press enter after changing an internal status of the CRT library through ctrl + z (this behaviour is kept for retrocompatibility with very old systems). If I'm not wrong it is called soft end of file. I don't think you can bypass it, since the EOF char is actually consumed by your getchar when you press enter, not when you press ctrl + z.
As reported here:
In Microsoft's DOS and Windows (and in CP/M and many DEC operating systems), reading from the terminal will never produce an EOF. Instead, programs recognize that the source is a terminal (or other "character device") and interpret a given reserved character or sequence as an end-of-file indicator; most commonly this is an ASCII Control-Z, code 26. Some MS-DOS programs, including parts of the Microsoft MS-DOS shell (COMMAND.COM) and operating-system utility programs (such as EDLIN), treat a Control-Z in a text file as marking the end of meaningful data, and/or append a Control-Z to the end when writing a text file. This was done for two reasons:
*
*Backward compatibility with CP/M. The CP/M file system only recorded the lengths of files in multiples of 128-byte "records", so by convention a Control-Z character was used to mark the end of meaningful data if it ended in the middle of a record. The MS-DOS filesystem has always recorded the exact byte-length of files, so this was never necessary on MS-DOS.
*It allows programs to use the same code to read input from both a terminal and a text file.
Other information are also reported here:
Some modern text file formats (e.g. CSV-1203[6]) still recommend a trailing EOF character to be appended as the last character in the file. However, typing Control+Z does not embed an EOF character into a file in either MS-DOS or Microsoft Windows, nor do the APIs of those systems use the character to denote the actual end of a file.
Some programming languages (e.g. Visual Basic) will not read past a "soft" EOF when using the built-in text file reading primitives (INPUT, LINE INPUT etc.), and alternate methods must be adopted, e.g. opening the file in binary mode or using the File System Object to progress beyond it.
Character 26 was used to mark "End of file" even if the ASCII calls it Substitute, and has other characters for this.
If you modify your code like that:
#include <stdio.h>
int main() {
while(1) {
char c = getchar();
printf("%d\n", c);
if (c == EOF) // tried with also -1 and 26
break;
}
return 0;
}
and you test it, on Windows you will see that the EOF (-1) it is not written in console until you press enter. Beore of that a ^Z is printed by the terminal emulator (I suspect). From my test, this behavior is repeated if:
*
*you compile using the Microsoft Compiler
*you compile using GCC
*you run the compiled code in CMD window
*you run the compiled code in bash emulator in windows
Update using Windows Console API
Following the suggestion of @eryksun, I successfully written a (ridiculously complex for what it can do) code for Windows that changes the behavior of conhost to actually get the "exit when pressing ctrl + d". It does not handle everything, it is only an example. IMHO, this is something to avoid as much as possible, since the portability is less than 0. Also, to actually handle correctly other input cases a lot more code should be written, since this stuff detaches the stdin from the console and you have to handle it by yourself.
The methods works more or less as follows:
*
*get the current handler for the standard input
*create an array of input records, a structure that contains information about what happens in the conhost window (keyboard, mouse, resize, etc.)
*read what happens in the window (it can handle the number of events)
*iterate over the event vector to handle the keyboard event and intercept the required EOF (that is a 4, from what I've tested) for exiting, or prints any other ascii character.
This is the code:
#include <windows.h>
#include <stdio.h>
#define Kev input_buffer[i].Event.KeyEvent // a shortcut
int main(void) {
HANDLE h_std_in; // Handler for the stdin
DWORD read_count, // number of events intercepted by ReadConsoleInput
i; // iterator
INPUT_RECORD input_buffer[128]; // Vector of events
h_std_in = GetStdHandle( // Get the stdin handler
STD_INPUT_HANDLE // enumerator for stdin. Others exist for stdout and stderr
);
while(1) {
ReadConsoleInput( // Read the input from the handler
h_std_in, // our handler
input_buffer, // the vector in which events will be saved
128, // the dimension of the vector
&read_count); // the number of events captured and saved (always < 128 in this case)
for (i = 0; i < read_count; i++) { // and here we iterate from 0 to read_count
switch(input_buffer[i].EventType) { // let's check the type of event
case KEY_EVENT: // to intercept the keyboard ones
if (Kev.bKeyDown) { // and refine only on key pressed (avoid a second event for key released)
// Intercepts CTRL + D
if (Kev.uChar.AsciiChar != 4)
printf("%c", Kev.uChar.AsciiChar);
else
return 0;
}
break;
default:
break;
}
}
}
return 0;
}
A: while(getchar() != EOF)
{
if( getchar() == EOF )
break;
}
return 0;
Here it is inconsistent.
If getchar() != EOF it will enter the loop, otherwise (if getchar() == EOF) it will not enter the loop. So, there is no reason to check getchar() == EOF inside the loop.
On the other hand, you call getchar() 2 times, you wait to enter 2 characters instead of only 1.

SELECT id, name, pass, count(*) over () as rows
FROM users
Keep in mind that this is telling you the number of rows returned by the query, not the number of rows in the table. However, if you specify a "TOP n" in your select, the rows column will give you the number of rows that would have been returned if you didn't have "Top n"
A: If you're trying to paginate the trick is to query one more record than you actually need for the current page. By counting the result (mysql_num_rows) and comparing that to your page size, you can then decide if there is a 'next page'.
If you were using mysql you could also use SQL_CALC_FOUND_ROWS() in your query, which calculates the number of rows that would be returned without the LIMIT clause. Maybe there is an equivalent for that in MsSQL?
A: I assume that you are inserting manually the first 2 rows of your table.
According to that, my idea is to just do a select where the id is more than 2 like this:
SELECT * FROM users WHERE id > 2;
I also assume that you are using PHP so mysql_num_rows will return you 0 if no data is found, otherwise it will return you the number of rows from your query and now you know that you need to do a while or some loop to retrieve the data after id number 2. | unknown | |

d7939 | train | When crafting a file like this it's always good to do so using Explorer or Notepad first, then write/adjust your code to match whatever was produced. Otherwise, it's harder to figure out if the problem is with your file or your code.
I believe the minimum requirements to make this work is Desktop.ini must be marked System and the parent directory must be marked ReadOnly (System may work there as well, but I know ReadOnly definitely does). So, your code is working with the right attributes, but there are still a few problems.
Your if ... else ... block is saying "If a file exists at this path, create a directory at that path, then delete the file at that path, then create a file at that path." Of course, the directory should not and cannot have the same path as the file. I assume you are deleting and recreating the file to clear the contents when it already exists, however File.Create() overwrites (truncates) existing files, making the calls to both File.Delete() and File.Exists() unnecessary.
More importantly is this line...
di.Attributes &= ~FileAttributes.ReadOnly;
...with which there are two problems. First, you are ANDing the directory's attributes with the negation of ReadOnly, which has the effect of removing ReadOnly and keeping the other attributes the same. You want to ensure ReadOnly is set on the directory, so you want to do the opposite of the code you used: OR the directory's attributes with ReadOnly (not negated)...
di.Attributes |= FileAttributes.ReadOnly;
Also, you need that attribute set regardless of whether you created the directory or not, so that line should be moved outside of the if ... else ....
Another issue is the successive calls to File.SetAttributes(). After those three calls the file's attributes will be only Hidden, since that was the value of the last call. Instead, you need to combine (bitwise OR) those attributes in a single call.
A couple of other minor tweaks...
*
*As you know since you are calling Dispose() on it, File.Create() returns a FileStream to that file. Instead of throwing it away, you could use it to create your StreamWriter, which will have to create one, anyways, under the covers. Better yet, call File.CreateText() instead and it will create the StreamWriter for you.
*Environment variables are supported in Desktop.ini files, so you don't have to expand them yourself. This would make the file portable between systems if, say, you copied it from one system to another, or the directory is on a network share accessed by multiple systems with different %SystemRoot% values.
Incorporating all of the above changes your code becomes...
// Create a new directory, or get the existing one if it exists
DirectoryInfo directory = Directory.CreateDirectory(@"C:\Users\np\Desktop\PUTEST");
directory.Attributes |= FileAttributes.ReadOnly;
string filePath = Path.Combine(directory.FullName, "desktop.ini");
string iconPath = @"%SystemRoot%\system32\SHELL32.dll";
string iconIndex = "-183";
using (TextWriter tw = File.CreateText(filePath))
{
tw.WriteLine("[.ShellClassInfo]");
tw.WriteLine("IconResource=" + iconPath + "," + iconIndex);
//tw.WriteLine("IconFile=" + iconPath);
//tw.WriteLine("IconIndex=" + iconIndex);
}
File.SetAttributes(filePath, FileAttributes.ReadOnly | FileAttributes.System | FileAttributes.Hidden);
One catch is that the above code throws an exception if you run it twice in succession. This is because the File.Create*() methods fail if the input file is Hidden or ReadOnly. We could use new FileStream() as an alternative, but that still throws an exception if the file is ReadOnly. Instead, we'll just have to remove those attributes from any existing input file before opening it...
// Create a new directory, or get the existing one if it exists
DirectoryInfo directory = Directory.CreateDirectory(@"C:\Users\np\Desktop\PUTEST");
directory.Attributes |= FileAttributes.ReadOnly;
string filePath = Path.Combine(directory.FullName, "desktop.ini");
FileInfo file = new FileInfo(filePath);
try
{
// Remove the Hidden and ReadOnly attributes so file.Create*() will succeed
file.Attributes = FileAttributes.Normal;
}
catch (FileNotFoundException)
{
// The file does not yet exist; no extra handling needed
}
string iconPath = @"%SystemRoot%\system32\SHELL32.dll";
string iconIndex = "-183";
using (TextWriter tw = file.CreateText())
{
tw.WriteLine("[.ShellClassInfo]");
tw.WriteLine("IconResource=" + iconPath + "," + iconIndex);
//tw.WriteLine("IconFile=" + iconPath);
//tw.WriteLine("IconIndex=" + iconIndex);
}
file.Attributes = FileAttributes.ReadOnly | FileAttributes.System | FileAttributes.Hidden;
I changed from using File to FileInfo since that makes this a little easier. | unknown | |

lunchMenu=['Steak', 'Fries', 'Burger', 'Chicken', 'Salad']
check_val = {'Breakfast': breakfastMenu, 'Dinner': dinnerMenu, "Lunch": lunchMenu}
data = [['ORDB10489', 'Lunch', "[('Coffee', 4), ('Salad', 10), ('Chicken', 8)]"],

['ORDK04121', 'Lunch', "[('Steak', 9), ('Chicken', 5)]"]]
df = pd.DataFrame(data, columns=['order_id', 'order_type', 'order_items'])
df["order_items"] = df["order_items"].apply(ast.literal_eval)
df["order_items"] = df.apply(lambda x: [i for i in x["order_items"] if i[0] in check_val.get(x["order_type"], [])], axis=1)
print(df)
Output:
order_id order_type order_items
0 ORDB10489 Lunch [(Salad, 10), (Chicken, 8)]
1 ORDZ00319 Dinner [(Fish&Chips, 9), (Pasta, 5)]
2 ORDB00980 Dinner [(Pasta, 6), (Fish&Chips, 10)]
3 ORDY10003 Breakfast [(Coffee, 2), (Cereal, 1)]
4 ORDK04121 Lunch [(Steak, 9), (Chicken, 5)]
A: So, I think there is a solution without any essential for loops. Just using some joins. But before we can achieve that, we have to bring the data to a more suitable shape.
flattened_items = df.order_items.apply(pd.Series).stack().reset_index().assign(
**{"order_item": lambda x:x[0].str[0], "item_count": lambda x:x[0].str[1]})
print(flattened_items.head())
level_0 level_1 0 order_item item_count
0 0 0 (Coffee, 4) Coffee 4
1 0 1 (Salad, 10) Salad 10
2 0 2 (Chicken, 8) Chicken 8
3 1 0 (Fish&Chips, 9) Fish&Chips 9
4 1 1 (Pasta, 5) Pasta 5
So essentially, I just flattened the list of tuple into two columns. Note, for your setup to work, you might need to run reset_index one on the original Dataframe df (otherwise it's like your sample from Dataframe)
Next we create a Dataframe that apps meals to items via
flattend_orders = pd.merge(df[["order_id", "order_type"]],
flattened_items[["level_0","order_item", "item_count"]],
left_index=True, right_on="level_0").drop("level_0", axis=1)
meal_dct = {"Breakfast": breakfastMenu, "Lunch": lunchMenu, "Dinner": dinnerMenu}
meal_df = pd.DataFrame.from_dict(meal_dct, orient="index").stack().reset_index(
).drop("level_1", axis=1).rename(columns={"level_0": "Meal", 0: "Item"})
which looks like
print(meal_df.head())
Meal Item
0 Breakfast Pancake
1 Breakfast Coffee
2 Breakfast Eggs
3 Breakfast Cereal
4 Lunch Steak
Now, we can just do an inner join on the order_type and order_item
merged = pd.merge(flattend_orders, meal_df, left_on=["order_type", "order_item"],
right_on=["Meal", "Item"]).drop(["Meal", "Item"], axis=1)
and we obtain
order_id order_type order_item item_count
0 ORDB10489 Lunch Salad 10
1 ORDB10489 Lunch Chicken 8
2 ORDK04121 Lunch Chicken 5
3 ORDZ00319 Dinner Fish&Chips 9
4 ORDB00980 Dinner Fish&Chips 10
5 ORDZ00319 Dinner Pasta 5
6 ORDB00980 Dinner Pasta 6
7 ORDY10003 Breakfast Coffee 2
8 ORDY10003 Breakfast Cereal 1
9 ORDK04121 Lunch Steak 9
Now, this is maybe already good enough, but you might prefer to have a list of tuples back. To this end:
merged.groupby(["order_id", "order_type"]).apply(lambda x: list(zip(x["order_item"],
x["item_count"]))).reset_index().rename(columns={0:"order_items"})
gives
order_id order_type order_items
0 ORDB00980 Dinner [(Fish&Chips, 10), (Pasta, 6)]
1 ORDB10489 Lunch [(Salad, 10), (Chicken, 8)]
2 ORDK04121 Lunch [(Chicken, 5), (Steak, 9)]
3 ORDY10003 Breakfast [(Coffee, 2), (Cereal, 1)]
4 ORDZ00319 Dinner [(Fish&Chips, 9), (Pasta, 5)]
Note that the ugliness here is due to converting data from (maybe) insufficient formats. Also all for loops and apples just come from data transformation.
Essentially, my answer can be summarized as:
pd.merge(df, df_meal)
if we assume just the right data format.
Btw, I just chose item_count as a name as a best guess.
A: This is something you probably want to do in an Apply-function. Given that the breakfastMenu, dinnerMenu and lunchMenu are defined on the top of the script, the following function would work:
def check_correct(x):
if x['order_type'] == 'lunch':
current_menu = lunchMenu
elif x['order_type'] == 'dinner':
current_menu = dinnerMenu
else:
current_menu= breakfastMenu
current_menu = [x.lower() for x in current_menu]
return_list = []
for item, _ in x['order_items']:
return_list.append(item.lower() in current_menu)
return return_list
You can create a new column inside the DataFrame with:
df.apply(check_correct, axis = 1). It will give you a list with the True and False mathes. The first line would result in the following output:
[False, True, True]
A: for index, row in df.iterrows():
new = []
if row["order_type"] == "Breakfast":
order_type = breakfastMenu
elif row["order_type"] == "Dinner":
order_type = dinnerMenu
elif row["order_type"] == "Lunch":
order_type = lunchMenu
else:
continue
a = row["order_items"][1:-1]
b = a.split(",")
for i in range(0,len(b),2):
meal = b[i].strip()[2:-1]
if meal in order_type:
new.append([meal, b[i+1]])
row["order_items_new"] = new
print(df["order_items_new"])
0 [[Salad, 10)], [Chicken, 8)]]
1 [[Fish&Chips, 9)], [Pasta, 5)]]

d7942 | train | The List.containsAll method behaves just as documented: it returns true if all the elements of the given collection belong to this collection, false otherwise. The docs say nothing about the order or cardinality of the elements.
The documentation for containsAll does not explicitly say how it determines whether an element belongs to the Collection. But the documentation for contains (which is implicitly specifying the semantics of "contains") does: it uses equals. Again, no mention of cardinality.
The containsAll method is declared in the Collection interface and re-declared in the List and Set interfaces, but it's first implemented in the Collection hierarchy by the AbstractCollection class, as follows:
public boolean containsAll(Collection<?> c) {
for (Object e : c)
if (!contains(e))
return false;
return true;
}
As far as I know, this implementation is inherited by most common classes that implement the Collection interface in the Java Collections framework, except for the CopyOnWriteArrayList class and other specialized classes, such as empty lists and checked and immutable wrappers, etc.
So, if you look at the code, you'll see that it fulfils the docs you quoted:
Returns true if this list contains all of the elements of the specified collection.
In the docs of the AbstractList.containsAll method, there's also an @implSpec tag, which says the following:
@implSpec
This implementation iterates over the specified collection, checking each element returned by the iterator in turn to see if it's contained in this collection. If all elements are so contained true is returned, otherwise false.
With regard to possible optimizations, they're all relayed to the different implementations of the contains method, which is also implemented by AbstractCollection in a naive, brute-force-like way. However, contains is overriden in i.e. HashSet to take advantage of hashing, and also in ArrayList, where it uses indexes, etc.
A: You can iterate over one list and remove elements by value from another, then check if another list size == 0. If it is, then that means all second list elements were present in first list at least as many times as in the second list.
public boolean containsAll(List<Character> source, List<Character> target) {
for (Character character : source) {
target.remove(character);
if (target.isEmpty()) {
return true;
}
}
return target.size() == 0;
}
HashMap will be more efficient if lists are huge
public static boolean containsAll(List<Character> source, List<Character> target) {
Map<Character, Long> targetMap = target.stream().collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));
for (Character character : source) {
Long count = targetMap.get(character);
if (count != null) {
if (count > 1) {
targetMap.put(character, --count);
} else {
targetMap.remove(character);
}
}
}
return targetMap.isEmpty();

d7945 | train | I would closely follow the relationship patterns in the documentation:
https://docs.sqlalchemy.org/en/13/orm/basic_relationships.html
As an example assuming you wanted a one-to-one relationship between owners and owndnis...
One to One
class Parent(Base):
__tablename__ = 'parent'
id = Column(Integer, primary_key=True)
child = relationship("Child", uselist=False, back_populates="parent")
class Child(Base):
__tablename__ = 'child'
id = Column(Integer, primary_key=True)
parent_id = Column(Integer, ForeignKey('parent.id'))
parent = relationship("Parent", back_populates="child")
Untested but following this pattern and in your case treating owners as the parent:
# Treated as Parent of One to One
class owners(db.Model):
__tablename__ = 'owners'
ownerid = db.Column('ownerid', db.String(60), primary_key=True) <--- changed primary key
name = db.Column('ownerdomainname', db.String(60), nullable=False)
spownerid = db.Column('spownerid', db.String(60))
dnis = db.relationship("owndnis", uselist=False, back_populates="owners") <--- note change
# child = relationship("Child", uselist=False, back_populates="parent")
# Treated as Child of One to One
class owndnis(db.Model):
__tablename__ = 'owndnis'
ownerid = db.Column('ownerid', db.String(60),
primary_key=True, db.ForeignKey('owners.ownerid')) <-- both a PK and FK
dnisstart = db.Column('dnisstart', db.String(20), nullable=False)
dnisend = db.Column('dnisend', db.String(20))
owner = relationship("owners", back_populates="owndnis") <--- added
# parent = relationship("Parent", back_populates="child")
I've used back_populates but per the docs:
As always, the relationship.backref and backref() functions may be used in lieu of the relationship.back_populates approach; to specify uselist on a backref, use the backref() function:
class Parent(Base):
__tablename__ = 'parent'
id = Column(Integer, primary_key=True)
child_id = Column(Integer, ForeignKey('child.id'))
child = relationship("Child", backref=backref("parent", uselist=False)) | unknown | |
d7946 | train | which is the default data grouping(default unit option) in highstock
There's a little flaw in the API (https://api.highcharts.com/highstock/series.column.dataGrouping.units) in units section. First it says that it defaults to:
units: [[
'millisecond', // unit name
[1, 2, 5, 10, 20, 25, 50, 100, 200, 500] // allowed multiples
], [
'second',
[1, 2, 5, 10, 15, 30]
], [
'minute',
[1, 2, 5, 10, 15, 30]
], [
'hour',
[1, 2, 3, 4, 6, 8, 12]
], [
'day',
[1]
], [
'week',
[1]
], [
'month',
[1, 3, 6]
], [
'year',
null
]]
and after that "Defaults to undefined." line appears. The first one is correct.
Highcharts automatically finds the best grouping unit from units array. So, in other words: units specifies which groupings can be applied if Highcharts decides that applying data grouping is a good idea.
Enable dataGrouping.forced and use only one key-value pair in units array if you want to make sure that this grouping will be used no matter what e.g.:
units: [[
'hour',
[3]
] // Data will always be grouped into 3 hours periods
These're just general rules - they should be enough to use data grouping successfully. | unknown | |
d7947 | train | You should not cache access tokens on the backend of a web application ,if you can store them client side and send them with each request.
In case you don't have possibility to store it at client side (possible case your API is talking to some message client like USSD,SMS etc),It will be expensive to get an OAuth access token, because it requires an HTTP request to the token endpoint. This case is a good example where you can cache tokens whenever possible.
You can make use of REDIS if you have multiple instances.
REMEMBER : Tokens are sensitive data, because they grant access to a user's resources. (Moreover, unlike a user's password, you can't just store a hash of the token.) Therefore, it's critical to protect tokens from being compromised. You can make use of encryption.Do check below links for more details :
https://auth0.com/docs/best-practices/token-best-practices.

https://learn.microsoft.com/en-us/azure/architecture/multitenant-identity/token-cache
As per Auth0 Token Best Practices
Store and reuse.
Reduce unnecessary roundtrips that extend your application's attack surface, and optimize plan token limits (where applicable) by storing access tokens obtained from the authorization server. Rather than requesting a new token, use the stored token during future calls until it expires. How you store tokens will depend on the characteristics of your application: typical solutions include databases (for apps that need to perform API calls regardless of the presence of a session) and HTTP sessions (for apps that have an activity window limited to an interactive session). For an example of server-side storage and token reuse, see Obtaining and Storing Access Tokens to Call External APIs in our Github repo | unknown | |
d7948 | train | The problem is most likely this line

= in C# is assignment; you're most likely looking for equality, which is ==
Changing the above to this should fix it for you.
if (N11 == N6 && N11 == N7)
A: To handle your comparison, you need:
if ((N11 == N6) && (N11 == N7))
Or, simplified:
if (N11 == N6 && N11 == N7)
Note the == (comparison) instead of = (assignment). Also, you need to do two separate comparisons to check to see if the three values are equal.
In addition, right now you're using int.Parse, but assigning to a double. You should likely use double.Parse instead:
double N1 = double.Parse(TB_S1.Text);
You may also want to consider using double.TryParse, as this will better handle errors in user input:

d7952 | train | I'm not sure your question has the right details.

I wonder if your original worksheet had aCollection object called Buttons
which contained, perhaps, a list of the buttons in the form of a class object, called Button (hence your error message) and which exposes the properties that are called in your code.
Without that collection and class, the code would be more like this:
Public Sub ChangeSomething()
Dim btn As Shape
With Application
'Check for correct data types.
If Not TypeOf .ActiveSheet Is Worksheet Then Exit Sub
If IsObject(.Caller) Then Exit Sub
'Acquire button
On Error Resume Next
Set btn = .ActiveSheet.Shapes(.Caller)

d7957 | train | The DatePicker gives you a date object. Instead of storing the entire value string just grab the day month and year Date(value).getYear() + '-' + Date(value).getMonth() + '-' + Date(value).getDate(). As for the times do the same as the dates. Store those values in the DB and then when you get them back you will have to convert them back to a date object so that the date picker can understand them.
Ultimately with this solution your just trying to store dates without the timezones. Make sure to state in your app that the times are for those areas.
A: You have to distinguish between the format the date/time is transported, saved vs. how the date will be shown to the user.

*For transportation and saving use UTC in a format that is easy computable (eg. ISO8601).
*For visualization to the user convert this value to the timezone and desired user format by using some helper library. | unknown | |

d7961 | train | I think you can vectorize your function like this:
import numpy as np
def func_vec(a, b):
ar = np.roll(a, 1, axis=0)
ar[0] = 0
ac = np.cumsum(ar, axis=0)
bc = np.maximum(b - ac, 0)
return np.maximum(a - bc, 0)
Quick test:
import numpy as np
def func(a, b):
n = np.copy(a)
m = np.copy(b)
for i in range(len(n)):
n[i] = np.where(n[i] >= m, n[i] - m, 0)
m = np.maximum(0, m - a[i])
if not m.any():
return n
return n
np.random.seed(100)
n = 100000
m = 10
num_max = 100
a = np.random.randint(num_max, size=(m, n))
b = np.random.randint(num_max, size=(1, n))
print(np.all(func(a, b) == func_vec(a, b)))
# True
However, your algorithm has an important advantage over the vectorized algorithm, which is that it stops the iteration when it finds that there is nothing else to subtract. This means that, depending on the size of the problem and the specific values (which is what determines when does the early stop happens, if at all), the vectorized solution may actually be slower. See for the above example:
%timeit func(a, b)
# 5.09 ms ± 78.5 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%timeit func_vec(a, b)
# 12.4 ms ± 939 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
You can, however, get something of a "best of both worlds" solution using Numba:
import numpy as np
import numba as nb
@nb.njit
def func_nb(a, b):
n = np.copy(a)
m = np.copy(b)
zero = np.array(0, dtype=a.dtype)

if not m.any():

But that is just for starters. You will also have to verify that the various parts such as the date/time are within acceptable ranges. To get an idea of just how complex it is to test for a valid GUID, look at the source code for one of the Guid constructors.

d7964 | train | The problem is you're adding constraints to a button that already has been properly constrained. While you could remove all the constraints and recreate them, that is really inefficient and would not be recommended.
I would recommend simply keeping a reference to the leading constraint, which will allow you to access it every time the button is tapped to modify the constant.
To do this, implement a property for your leading constraint, like so:
var leadingConstraint: NSLayoutConstraint!
When you create this button, you'll want to properly constrain it as well. Here is where you'll be creating that special leading constraint. This is done outside of the button action function, perhaps in viewDidLoad:
button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
//...
leadingConstraint = button.leadingAnchor.constraintEqualToAnchor(view.leadingAnchor, constant: 0)
NSLayoutConstraint.activateConstraints([
leadingConstraint,
button.topAnchor.constraintEqualToAnchor(view.topAnchor, constant: 390),
button.widthAnchor.constraintEqualToConstant(75),
button.heightAnchor.constraintEqualToConstant(75)
])
Now when the button is tapped, you won't need to set translatesAutoresizingMaskIntoConstraints, and you can simply update the constant of the existing leading constraint.
@IBAction func start(sender: UIButton) {
button.hidden = false
let randomNumber = Int(arc4random_uniform(180) + 30)
leadingConstraint.constant = CGFloat(randomNumber)

d7971 | train | x is an unsigned char, meaning it is between 0 and 256. Since an int is bigger than a char, casting unsigned char to signed int still retains the chars original value. Since this value is always >= 0, your if is always true.
A: All the values of an unsigned char can fir perfectly in your int, so even with the cast you will never get a negative value. The cast you need is to signed char - however, in that case you should declare x as signed in the function signature. There is no point lying to the clients that you need an unsigned value while in fact you need a signed one.
A: Even with the cast, the comparison is still true in all cases of defined behavior. The compiler still determines that (signed int)0 has the value 0, and still determines that (signed int)x) is non-negative if your program has defined behavior (casting from unsigned to signed is undefined if the value is out of range for the signed type).
So the compiler continues warning because it continues to eliminate the else case altogether.
Edit: To silence the warning, write your code as
#define VALUE 0
int test(unsigned char x) {
#if VALUE==0
return 1;
#else
return x>=VALUE;
#endif
}
A: The #define of VALUE to 0 means that your function is reduced to this:
int test(unsigned char x) {
if (x>=0)
return 0;
else
return 1;
}
Since x is always passed in as an unsigned char, then it will always have a value between 0 and 255 inclusive, regardless of whether you cast x or 0 to a signed int in the if statement. The compiler therefore warns you that x will always be greater than or equal to 0, and that the else clause can never be reached. | unknown | |

To fix it, just pass the getter function, not its result, to the decorator, and make the call inside the wrapper function, inside the decorator. (For that, just leave the parentheses out):
def decorator(request_id_getter=None, *d_args, **d_kw):
def logger(func): # other arguments than the first positional arg here are not used at all.

d7974 | train | You may want to try live binding the event and see if that makes a difference. The other issue may be your css as the italic tag is an inline element you may not have a decent target area for the click event (this space can vary from browser to browser). You may want to try binding to the parent button tag instead as this should contain the child element. Also since there is no default action to an italic tag or button there is no reason to include a preventDefault() or return false.
$(function(){
$(document).on("click", "#serach-button", function() {
if($("#head-form").is(":visible")){
$("#head-form").fadeOut();
}else{
$(".menu").hide();
$("#head-form").show();
}
});
});
Also take note of how you are spelling your class names and id's as pointed out by other people in this thread there are several misspellings and several answers have tried correcting that spelling for you.
A: Actually I will upvote your question because it leads to an issue I didn't know before :
elements embedded inside a buttton in FF will lose their click event.
$("#p").click(function() {
alert('hello');
});
document.getElementById('i').addEventListener('click', function(e) {
alert('hello2');
}, false);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="b">
<img id="i" src="http://lorempixel.com/25/20" />
<em id="em">elements embedded inside a buttton in FF will lose their click event.</em>
</button>
I don't know if it's a bug as specs only state that
It is illegal to associate an image map with an IMG that appears as the contents of a BUTTON element.
So for you the solution is to reattach the event to the button (either by giving the serach-button id to your real button element, or with $("#serach-btn").parent().click(function() {.
jQuery(document).ready(function($) {
$("#serach-button").parent().click(function() {
alert('hello');
});
$("#real-button").click(function() {
alert('hello');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="button-responsiv-list">
<button class="button-responsiv"><i id="serach-button" class="glyphicon glyphicon-search"></i>

<button class="button-responsiv" id="real-button"><i id="navbar-button" class="glyphicon glyphicon-align-justify"></i>

<i id="sidebar-button-hide" style="display:none;" class="glyphicon glyphicon-indent-left"></i>
</button>
</div>
A: Your button has this class .search-btn so, you can try this:
$(function(){
$(".search-btn").click(function() {
if($("#head-form").is(":visible")){
$("#head-form").fadeOut();
}else{
$(".menu").hide();
$("#head-form").show();
}
});
});
A: Try changing "serach" to "search".
Also you can change jQuery to $:
$(document).ready(function () {
$("#search-button").click(function () {
var display = $("#head-form").css("display");
if (display != "none") {
$("#head-form").fadeOut();
} else {
$(".menu").hide();
$("#head-form").show();
}
});

d7975 | train | Oh, you're trying to rename the files? You can't use sed for that; that changes the contents of the files, without renaming them. Here's how I might do the renaming:
for a in Dog_1*.csv; do
mv "$a" "Dog_2${a#Dog_1}"
done
A: Since the question regards renaming of files, you may be better off renameing them.
This application has syntax quite similar to sed's:
rename 's/Dog_1/Dog_2/' *.csv
And you may as well perform global renamings, if that is the case:
rename 's/Dog_1/Dog_2/g' *.csv | unknown | |
d7976 | train | Solved. Installed 32-bit Python by mistake, should be 64-bit for this. | unknown | |
d7977 | train | If the entries in the table should be "expired" (and removed) at certain times, then here is a possible solution, using only a single timer:
First of all use a priority queue where the "priority" is the expiration time. You can of course use any other table-like structure, but keep it sorted on the expiration time (it simplify things later).
Then have your single recurring timer, which is triggered ten, twenty or maybe more times per second.
When the timer is triggered, you get the current time, and simply remove all elements in the table whose expiration time have passed (comparing its expiration time with the current time). If the table is sorted on expiration date, it's a very simple loop where you compare the time from the "top" element, and if expired then "pop" the top element.
You can use the same or similar techniques for just about any timing-related issue. | unknown | |
d7978 | train | Well this is quite old question, I answer it because I run to it when looking for the same problem.
Actually Mootools Acordion adds this much inline CSS:
padding-top: 0px; border-top-style:
none; padding-bottom: 0px; border-bottom-style: none;
overflow: hidden; opacity: 1;
The solutions I found for this are fixes that have to be applied after calling the new Fx.Accordion. I also agree that feels wrong to fix with !important CSS fixing. So I also looked for other options.
Option 1, set back the css as you want:
$$('.acordion3_content').setStyles({
border: '3px solid #0F0',
'overflow-y': 'auto',
});
Option 2, create one more div inside or outside it. I did this option to get a scroll div I could have events connected to. Like this I could have a scroll inside the accordion's content without it being affected of Fx.Acordion's CSS. | unknown | |
d7979 | train | Use :first selector with .find() to get input descendants.
$('tr').find(':text:first').css('background-color','#C0C0C0');
Demo
$("tr:text:first") in your code, finds tr with :text(type="text") which is invalid.
<tr> does not have :text
A: Have you tried $("tr input:first-child").css('background-color','#C0C0C0'); ?
A: Also, if you can't get jQuery to work, it would be simple enough to add a class to the first table cell in each table row and style it that way, forgoing the time it would take to load jQuery(if that is an issue, as I have sometimes found it to be). | unknown | |

d7982 | train | First of all, you should decide if dependency injection is really what you need. Basic idea of DI: instead of factories or objects themselves creating new objects, you externally pass the dependencies, and pass the instantiation problem to someone else.
You suppose to go all in with it if you rely on framework, that is why no way of using new along with DI. You cannot pass/inject a class into the scala object, here is a draft of what you can do:
Play/guice require some preparation.
Injection Module to tell guice how to create objects (if you cannot do this if annotations, or want to do it in one place).
class InjectionModule extends AbstractModule {
override def configure() = {
// ...
bind(classOf[MyClass])
bind(classOf[GlobalContext]).asEagerSingleton()
}
}
Inject the injector to be able to access it.
class GlobalContext @Inject()(playInjector: Injector) {
GlobalContext.injectorRef = playInjector
}
object GlobalContext {
private var injectorRef: Injector = _
def injector: Injector = injectorRef
}
Specify which modules to enable, because there can be more than one.
// application.conf
play.modules.enabled += "modules.InjectionModule"
And finally the client code.
object Toyota extends Car {
import GlobalContext.injector
// at this point Guice figures out how to instantiate MyClass, create and inject all the required dependencies
val myClass = injector.instanceOf[MyClass]
...
}
A simple situation expanded with a frameworks help. So, you should really consider other possibilities. Maybe it would be better to pass the configs as an implicit parameter in your case?
For dependency injection with guice take a look at:
ScalaDependencyInjection with play and Guice wiki | unknown | |

d7985 | train | Well the first thing you should do is remove the code you added and get back to a version that complies. Then try again. You should also supply some code because the errors are not enough to answer this problem on their own.
You should also know that the R.java file is created each time you compile the app. The error from the R.java file probably indicates that there is a problem with the way you have coded the fragment navigation drawer. Check to see if you have used any spaces in the name, the R.java error shows an underscore and a hyphen. This may indicate that there is a problem with the name.
I would also recommend looking up some youtube videos explaining how to use the LogCat output to identify errors.
You should also read through the Google documentation on navigation drawer http://developer.android.com/training/implementing-navigation/nav-drawer.html and compare the example code with the code you have written.

d7986 | train | What you have is not YAML with embedded JSON, it is YAML with some the value for annotations being
in YAML flow style (which is a superset of JSON and thus closely resembles it).
This would be
YAML with embedded JSON:
api: v1
hostname: abc
metadata:
name: test
annotations: |
{
"ip" : "1.1.1.1",
"login" : "fad-login",
"vip" : "1.1.1.1",
"interface" : "port1",
"port" : "443"
}
Here the value for annotations is a string that you can hand to a JSON parser.
You can just load the file, modify it and dump. This will change the layout
of the flow-style part, but that will not influence any following parsers:
import sys
import ruamel.yaml
file_in = Path('input.yaml')
yaml = ruamel.yaml.YAML()
yaml.preserve_quotes = True
yaml.width = 1024
data = yaml.load(file_in)
annotations = data['metadata']['annotations']
annotations['ip'] = type(annotations['ip'])('4.3.2.1')
annotations['vip'] = type(annotations['vip'])('1.2.3.4')
yaml.dump(data, sys.stdout)
which gives:
api: v1
hostname: abc
metadata:
name: test
annotations: {"ip": "4.3.2.1", "login": "fad-login", "vip": "1.2.3.4", "interface": "port1", "port": "443"}
The type(annotations['vip'])() establishes that the replacement string in the output has the same
quotes as the original.
ruamel.yaml currently doesn't preserve newlines in a flow style mapping/sequence.
If this has to go back into some repository with minimal chances, you can do:
import sys
import ruamel.yaml
file_in = Path('input.yaml')
def rewrite_closing_curly_brace(s):
res = []
for line in s.splitlines():
if line and line[-1] == '}':
res.append(line[:-1])
idx = 0
while line[idx] == ' ':
idx += 1
res.append(' ' * (idx - 2) + '}')
continue
res.append(line)
return '\n'.join(res) + '\n'
yaml = ruamel.yaml.YAML()
yaml.preserve_quotes = True
yaml.width = 15
data = yaml.load(file_in)
annotations = data['metadata']['annotations']
annotations['ip'] = type(annotations['ip'])('4.3.2.1')
annotations['vip'] = type(annotations['vip'])('1.2.3.4')
yaml.dump(data, sys.stdout, transform=rewrite_closing_curly_brace)
which gives:
api: v1
hostname: abc
metadata:
name: test
annotations: {
"ip": "4.3.2.1",
"login": "fad-login",
"vip": "1.2.3.4",
"interface": "port1",
"port": "443"
}
Here the 15 for width is of course highly dependent on your file and might influence other lines if they
were longer. In that case you could leave that out, and make the wrapping
that rewrite_closing_curly_brace() does split and indent the whole flow style part.
Please note that your original, and the transformed output are, invalid YAML,
that is accepted by ruamel.yaml for backward compatibility. According to the YAML
specification the closing curly brace should be indented more than the start of annotation | unknown | |

d7988 | train | I'm not sure if the WSDL is valid or not but what you are trying to do won't work. Svcutil can generate code only for WSDL files of version 1.1. Yours is a WSDL version 2.0.
The WSDL validator you pointed in your question returns the following message when given your WSDL:
faultCode=INVALID_WSDL: Expected element 'http://schemas.xmlsoap.org/wsdl/:definitions'.
It parses the file as WSDL 1.1. and expects the root to be definitions, but that changed in WSDL 2.0 to description.
If you have a valid WSDL 2.0 file, Svcutil2 might be able to generate the code for you, but this tool isn't stable yet.
To validate the WSDL, I guess you could use the validator from The Woden project, which isn't stable either, but is basically the only one that I know that has moved passed the "toy project" status.
The idea is this: version 1.1 is still the "de facto" language when taking WSDL. Not many WS frameworks have adopted WSDL 2.0 so (just my 2 cents!) I think it's better to stick with "the standard" untill support is fully matured for WSDL 2.0.

d7990 | train | OK if you find this error is because of the way the data is being passing
Ex: ?page=1&sort=name&direction:asc is not a CakePHP way of handling params.
A right format url in cake should be nice looking like this: domain.com/2/name/asc
The way I end it up passing the params in routes.php:
$routes->connect('/productoptions/:page/:sort/:direction', ['controller' => 'Productoptions', 'action' => 'index'], ['param' => ['page'], 'param2' => ['sort'], 'param3' => ['direction'] ]);
So I can use $this->request->params['page] , $this->request->params['direction] etc...
In this way, I use CakePHP way of passing and handling params instead of $_GET | unknown | |

d7992 | train | $ab = 0;
$xy = 1;
echo "<table>";
$i = 0;
while ($i < 5) {
echo "<tr><td>$ab</td><td>$xy</td></tr>";
$ab += $xy;
$xy += $ab;
$i++;
}
echo "</table>";
For explanation :
Compared to the "for" loop, you have to initialize the "counter" before opening the loop [ $i = 0 ]
Inside the loop, you specify the condition to continue the loop [ $i < 5 ]
And somewhere into the loop, you increase your "counter" [ $i++ ]
Your "counter" can be increased or decreased, or directly set ; it's all about your code logic and what are your needs.
You can also break the loop whenever you want in case you need to, see an example :
while ($i < 5) {
echo "<tr><td>$ab</td><td>$xy</td></tr>";
$ab += $xy;
$xy += $ab;
if ($ab == 22) { // If $ab is equal to a specific value
/* Do more stuff here if you want to */
break; // stop the loop here
}
$i++;
}
This example also work with the "for" loop.
And there is also another keyword, "continue", used to tell to "jump" to the next loop iteration :
while ($i < 5) {
$i++; // Don't forget to increase "counter" first, to avoid infinite loop
if ($ab == 22) { // If $ab is equal to a specific value
/* Do more stuff here if you want to */
continue; // ignore this iteration
}
/* The following will be ignored if $ab is equal to 22 */
echo "<tr><td>$ab</td><td>$xy</td></tr>";
$ab += $xy;
$xy += $ab;
}
A: To replace a for loop with a while loop, you can declare a variable before you initiate the while loop which will indicate the current iteration of the loop. Then you can decrement/increment this variable upon each iteration of the while loop. So you would have something like this:
$counter = 0;
while ($counter < 5) {
echo "";
echo "<td>" . $ab . "</td><td>" . $xy . "</td>";
$ab += $xy;
$xy += $ab;
echo "</tr>";
$counter++;
}
in general:
for ($i = 0; $i < x; $i++) {
do stuff
}
is equivalent to:
$counter = 0;
while ($counter < x){
do stuff
counter++;

Check out PEiD, it can to do this automatically (along with detecting packers, etc). | unknown | |
d7994 | train | That quote is talking about a scenario where you can return a meaningful response without actually finishing all the work required by the request. For instance you might upload a file to be processed and respond immediately with a processing ID, but pass the processing to another thread. Later on the client could make another request with that ID to find out if processing completed.
An asynchronous servlet scenario would hand off processing to another thread to do the work while blocking the request. But the blocked request would not tie up a servlet request thread during processing like a normal synchronous servlet request.
Suppose you had a single threaded processor and 10 requests were made at the same time. With a synchronous servlet that waited for the processing to finish, you'd have 10 blocked request threads + 1 processor thread. But with an asynchronous servlet, you'd have 0 blocked threads + 1 processor thread. That's a pretty significant gain. | unknown | |

d8000 | train | I faced the same problem once and solved it by creating a function (or a class static method) to handle my option lists.
To print out your options you will have to cycle through them anyway, so while you cycle there is nothing bad in checking for each one if it must be the currently selected.
Just create a function like:
function printSelectOptions($dataArray, $currentSelection) {
foreach ($dataArray as $key => $value) {
echo '<option ' . (($key == $currentSelection) ? 'selected="selected"' : '') . ' value="' . $key . '">' . $value . '</option>';
}
}
Giving $dataArray as your key/value options array, and $currentSelection as the key of the selected option.
So in your code you will have just calls to this function, like:
<select id='mySelect' name='mySelect'>
<?php echo printSelectOptions($gifts, $gift); ?>
</select>
This should do the work!
EDIT: Adding sample to work with select multiple...
<?php
$options = array( 1 => "Test 1",
2 => "Test 2",
3 => "Test 3");
$selected = array(1, 3);
function printSelectOptions($dataArray, $selectionArray) {
foreach ($dataArray as $key => $value) {
echo '<option ' . (in_array($key, $selectionArray) ? 'selected="selected"' : '') . ' value="' . $key . '">' . $value . '</option>';
}
}
?>
<select multiple>
<?php echo printSelectOptions($options, $selected); ?>
</select>
The trick is passing the selected values as an array of keys, instead of a single key. In the sample I provided dummy arrays, but obviously you'll have to build yours from database... :)
EDIT: Select multi with arrays taken from the question...
<?php
$gifts = array("Standard" => "Standard", "Gift_ID_Req" => "Require Program ID", "Not_Enrolled" => "Do not Enroll");
$gift = array($row['gift_privacy']);
function printSelectOptions($dataArray, $selectionArray) {
foreach ($dataArray as $key => $value) {
echo '<option ' . (in_array($key, $selectionArray) ? 'selected="selected"' : '') . ' value="' . $key . '">' . $value . '</option>';
}
}
?>
<select multiple>
<?php echo printSelectOptions($gifts, $gift); ?>
</select>
EDIT: Explode multiple selected values
If you have mutliple selected values as a comma separated string, you just have to explode it before passing to the function I provided...
$selectedOptionsArray = explode(',', $selectedOptionsString);
So the ending code will look like...
<?php
$gifts = array("Standard" => "Standard", "Gift_ID_Req" => "Require Program ID", "Not_Enrolled" => "Do not Enroll");
$gift = explode(',', $row['gift_privacy']);
function printSelectOptions($dataArray, $selectionArray) {
foreach ($dataArray as $key => $value) {
echo '<option ' . (in_array($key, $selectionArray) ? 'selected="selected"' : '') . ' value="' . $key . '">' . $value . '</option>';
}
}
?>
<select multiple>
<?php echo printSelectOptions($gifts, $gift); ?>
</select>
A: You could use a function like this to simplify it:
<?php
function renderOption($key, $value, $current) {
echo '<option value="' . $key . '"' . ($key == $current ? ' selected="selected"' : '') . '>' . $value. '</option>';
}
?>
<select name="gift_privacy">
<?php
$gifts = array("Standard" => "Standard", "Gift_ID_Req" => "Require Program ID", "Not_Enrolled" => "Do not Enroll");
$gift = $row['gift_privacy'];
foreach($gifts as $key => $value)
renderOption($key, $value, $gift);
?>
</select>
A: Use simpler method:
<?php
echo '<option '.($key == $gift ? 'selected="selected" ' : '').'value="'. $key .'">'. $value .'</option>';
?>
Edit: second option
echo '<option '.selected_option($key, $gift).'value="'. $key .'">'. $value .'</option>';
function selected_option($val1, $val2){
if($val1 == $val2){
return 'selected="selected" ';
}else{
return '';
}
}
A: There is nothing wrong with what you have, and this, or something very similar is the typical approach to this problem.
You would/could wrap it in an actual function, say print_select( $array, $selected ); which would/could print out the entire <select> including the select themselves.
The final code might be:
print_select( $gifts, $selected_gift );
print_select( $colors, $selected_color );
// etc | unknown |
