21,654,981 | 0 | How do I add a column that points to another table in a Rails database? <p>Let's say I currently have a table titled "Report" and within Report, there are a bunch of strings, integers, timestamps, etc.</p> <p>Now, I want to somehow be able to see who is currently working on a certain report - all I need are names, but the key is it could be more than one name so just adding a string column to the Report table wouldn't work. Plus, the names would keep changing - at one point, "Steve" and "John" could be working on a report, but once "Steve" stops, I need to be able to get rid of his name from the table.</p> <p>I have a feeling that the correct way to do this is by: </p> <ul> <li>creating a new table titled "Viewers" and having just one string field (for the person's name) in there. I'd add rows to this table when a new viewer is detected.</li> <li>linking to indices within the Viewers table from the Report table. When a person stops viewing the report, the respective index is destroyed.</li> </ul> <p>I think that makes sense logically, but I'm hesitant to implement this without being sure that this is the way to go. Any help/feedback/suggestions would be appreciated!</p> <p>Edit:</p> <p>I created a model for my join table and it auto-generated a migration and added an integer "viewer_id" and an integer "report_id" like Vimsha suggested below. However, I can't correctly implement the join tables in my code for some reason - when I want to add to the new Table (report_viewers), I say:</p> <pre><code>@viewer = ReportViewer.new @viewer.viewer_id = get_current_user[:id] @viewer.report_id = this_report.id @viewer.save </code></pre> <p>However, when I access the table via </p> <pre><code>ReportViewer.where(:report_id => my_report.id).last.viewer_id.name (the viewer table has a string name) </code></pre> <p>it gives me a nil class.

280,727 | 0 | <p>I don't think it's a good idea to create one class per method. You could instead create a static only methods class, named e.g StringUtils and implement the methods. This way you would call:</p> <p>String lowerCaseString = StringUtils.lowercase( targetString );</p> <p>This would also offer you intellisense help while you are typing. The list of your classes will go otherwise too big. Even for this simple example, you should implement more than one Lowercase classes, so that you could also cater for circumstances that the CulutureInfo must be taken into consideration.</p> <p>I don't think this breaks OO principles in any way or that is bad design. In other languages, Ruby for example, you could add your methods directly to String class. Methods that end with ! denote that the original object is modified. All other methods return a modified copy. Ruby on Rails framework adds some methods to the String class and there is some debate about whether this is a good technique or not. It is definitely handy though.</p> |

This will also mean that many of the method and property names may not be completely familiar to non-Monotouch developers, but I am just looking for an approach.</p> <p>I currently have code that allows users to annotate images (jpg, png) using the TouchesMoved and TouchesBegan events on a UIView. This works well and accomplishes what I need.</p> <p>However, when working with an existing PDF file, it seems that the majority of the CGPDF functionality is centered around creating new files rather than editing existing ones.</p> <p>The only approach that I have been able to come up with is the following:</p> <ol> <li><p>When the UIView is opened, create a temporary file and set the PDF context to that file (UIGraphics.BeginPDFContext(filename)).</p></li> <li><p>Create a new CGPDFDocument from the original file and then draw each page from the original PDF into the current context, which will be the new temporary file.</p></li> <li><p>Destroy the original PDF document created in step 2.</p></li> <li><p>Show the user the first page and then let them draw on it, with the drawing commands being sent to the new file's context. There will also be methods to allow the user to change pages.</p></li> <li><p>When the user is done, close the PDF context, which will save all of the annotations to the new PDF file.</p></li> </ol> <p>This seems like it has the potential to be an enormous memory and performance hog, so I am wondering if there is any other way to approach this?</p> |
26,542,261 | 0 | Contact form design issue in CSS <p>I'm trying to code the below contact form in HTML&CSS.. The issue is how to make the inputs, textarea and the post button in one container and at by taking in consideration that there is a label for each one (out of the container).</p> <p><img src="https://i.stack.imgur.com/46ShF.png" alt="enter image description here"></p> <p>For the name, the label is on the right.

2,584,307 | 0 | <p>Yes, this is normal. It's not a problem that your test code is longer than your production code.</p> <p>Maybe your test code could be shorter than it is, and maybe not, but in any case you don't want test code to be "clever", and I would argue that after the first time of writing, you don't want to refactor test code to common things up unless absolutely necessary. For instance if you have a regression test for a past bug, then unless you change the public interface under test, don't touch that test code. Ever. If you do, you'll only have to pull out some ancient version of the implementation, from before the bug was fixed, to prove that the new regression test still does its job. Waste of time. If the only time you ever modify your code is to make it "easier to maintain", you're just creating busy-work.</p> <p>It's usually better to add new tests than to replace old tests with new ones, even if you end up with duplicated tests. You're risking a mistake for no benefit. The exception is if your tests are taking too long to run, then you want to avoid duplication, but even that might be best done by splitting your tests into "core tests" and "full tests", and run all the old maybe-duplicates less frequently.</p> <p>Also see <a href="http://stackoverflow.com/questions/2556594/sqlites-test-code-to-production-code-ratio">SQLite's test code to production code ratio</a></p> |
32,734,951 | 0 | <p>You are getting it wrong, <a href="https://msdn.microsoft.com/en-us/library/system.linq.enumerable.range(v=vs.100).aspx">Enumerable.Range</a> has second parameter as <code>count</code>, it should be:-</p> <pre><code>if (!Enumerable.Range(settingsAgeFrom, (settingsAgeTo - settingsAgeFrom) + 1) .Contains(age)) </code></pre> <p>So by this, your range will be 18 - 20 instead of 18 - 37 (which your current code is producing).</p> |
9,914,065 | 0 | <p>Well, the other answer is probably better, but I wrote this anyway, so I'm posting it:</p> <p>Needs:</p> <pre><code>using System.Text.RegularExpressions; </code></pre> <p>Code: </p> <pre><code>string str = "B82V16814133260"; string[] match = Regex.match(str, @"^([\d\w]+?\w)(\d+)$").Groups; string left = match[1]; string right = match[2]; </code></pre> |
6,685,784 | 0 | <p>As a1ex07 says in a comment, your code looks more like what you would put in <code>operator=</code> than in a copy constructor.</p> <p>First of all, a copy constructor is initializing a brand new object. A check like <code>if (this != &p)</code> doesn't make much sense in a copy constructor; the point you are passing to the copy constructor is never going to be the object that you are initializing at that point (since it's a brand new object), so the check is always going to be <code>true</code>.</p> <p>Also, doing things like <code>if (label != NULL)</code> is not going to work, because <code>label</code> is not yet initialized. This check might return <code>true</code> or <code>false</code> in random ways (depending if the uninitialized <code>label</code> is <code>NULL</code> by chance).</p> <p>I would write it like this:</p> <pre><code>GPSPoint(const GPSPoint& p) : lat(p.lat), lon(p.lon), h(p.h) { if (p.label != NULL) { label = new char[strlen(p.label) + 1]; strcpy(label, p.label); } else { label = NULL; } } </code></pre> <p>Maybe making <code>label</code> a <code>std::string</code> instead of a C-style <code>char*</code> would be a better idea, then you could write your copy constructor purely using an initializer list:</p> <pre><code>class GPSPoint { private: double lat, lon, h; std::string label; public: // Copy constructor GPSPoint(const GPSPoint& p) : lat(p.lat), lon(p.lon), h(p.h), label(p.label) { } } </code></pre> |
30,701,258 | 0 | <p>The createPolygon function needs to return the resulting polygon to GeoXml3 so it can manage it.</p> <pre><code>function addMyPolygon(placemark) { var polygon = geoXml.createPolygon(placemark); google.maps.event.addListener(polygon, 'click', function(event) { var myLatlng = event.latLng; infowindow.setContent("<b>"+placemark.name+"</b><br>"+placemark.description+"<br>"+event.latLng.toUrlValue(6)); infowindow.setPosition(myLatlng); infowindow.open(map); }); return polygon; }; </code></pre> <p>Also, if you are going to use <code>event</code> inside the polygon 'click' listener it needs to be defined.</p> <p><a href="http://www.geocodezip.com/geoxml3_test/v3_SO_geoxml3_createPolygon.html" rel="nofollow">working example</a></p> |

30,604,353 | 0 | <p>Sometimes this problem happens when you <strong>don´t make any calls to some of Pygames <em>event queue functions</em> in each frame</strong> of your game, as the <a href="http://www.pygame.org/docs" rel="nofollow">Documentation</a> states.</p> <p><strong>If you are not using any other event functions</strong> in your main game, you <em>should</em> <strong>call <a href="http://www.pygame.org/docs/ref/event.html#pygame.event.pump" rel="nofollow"><code>pygame.event.pump()</code></a> to allow Pygame to handle internal actions</strong>, such as joystick information.</p> <p>Try the following updated code:</p> <pre><code>while True: pygame.event.pump() #allow Pygame to handle internal actions joystick_count = pygame.joystick.get_count() for i in range(joystick_count): joystick = pygame.joystick.Joystick(i) joystick.init() name = joystick.get_name() axes = joystick.get_numaxes() hats = joystick.get_numhats() button = joystick.get_numbuttons() joy = joystick.get_axis(0) print(name, joy) </code></pre> <p><strong>An alternative</strong> would be to <strong>wait for events generated by your joystick</strong> (such as <code>JOYAXISMOTION</code>) by using the <code>pygame.event.get()</code> function for instance:</p> <pre><code>while True: #get events from the queue for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() if event.type == pygame.JOYAXISMOTION and event.axis == 0: print(event.value) joystick_count = pygame.joystick.get_count() for i in range(joystick_count): joystick = pygame.joystick.Joystick(i) joystick.init() #event queue will receive events from your Joystick </code></pre> <p>Hope this helps a little bit :)</p> |

20,959,928 | 0 | <p>You did not define the label <code>playerRollingForHit</code>... at least not in the code you are showing. This is a problem.</p> <p>As was pointed out by others, not having an idea of code structure is a much bigger problem. A <code>GoTo</code> statement, while legal should be used sparingly. And you should consider making your code more re-usable. For example, you can create your own data type:</p> <pre><code>Public Type player health As Integer strength As Integer ' whatever other properties you might have... End Type </code></pre> <p>And then you can create an array of players:</p> <pre><code>Dim players( 1 To 2 ) as player </code></pre> <p>This means you will be able to loop over the players, and "player 1 attacks player 2" can use the same code as "player 2 attacks player 1" (if they have the same rules). Similarly, you might want to create your own function "rollBetween" which allows you to roll different dice with a simple instruction.</p> <pre><code>Function rollBetween(n1 As Integer, n2 As Integer) ' roll a number between n1 and n2, inclusive rollBetween = Round(Rnd * (n2 - n1 + 1) - 0.5, 0) + n1 End Function </code></pre> <p>Putting it all together, for fun, I created some code that may help you understand what I'm talking about. Note - the rules here are not the same rules you used, but it's the same principle; as players get more strength, they become more immune to attack, and their attacks become stronger. I hope you can learn something from it, and have fun creating your game!</p> <pre><code>Option Explicit Public Type player health As Integer strength As Integer End Type Sub monsters() ' main program loop ' can have more than two players: just change dimension of array ' and rules of "who attacks whom" Dim players(1 To 2) As player Dim attacker As Integer Dim defender As Integer initPlayers players attacker = rollBetween(1, 2) ' who goes first: player 1 or 2 Debug.Print "Player " & attacker & " gets the first roll" While stillAlive(players) defender = (attacker Mod 2) + 1 playTurn players, attacker, defender attacker = defender ' person who was attacked becomes the attacker Wend MsgBox winner(players()) End Sub '------------------------------ ' functions that support the main program loop 'monsters': Function rollBetween(n1 As Integer, n2 As Integer) ' roll a number between n1 and n2, inclusive rollBetween = Round(Rnd * (n2 - n1 + 1) - 0.5, 0) + n1 End Function Sub initPlayers(ByRef p() As player) ' initialize the strength of the players etc Dim ii For ii = LBound(p) To UBound(p) p(ii).health = 10 p(ii).strength = 1 Next End Sub Function stillAlive(p() As player) As Boolean ' see whether players are still alive ' returns false if at least one player's health is less than 0 Dim ii For ii = LBound(p) To UBound(p) If p(ii).health <= 0 Then stillAlive = False Exit Function End If Next ii stillAlive = True End Function Sub playTurn(ByRef p() As player, n As Integer, m As Integer) ' attack of player(n) on player(m) Dim roll As Integer ' see if you can attack, or just heal: roll = rollBetween(1, 2) Debug.Print "player " & n & " rolled a " & roll If roll = 1 Then ' roll for damage roll = rollBetween(1, 4 + p(n).strength) ' as he gets stronger, attacks become more damaging Debug.Print "player " & n & " rolled a " & roll & " for attack" If p(m).strength > roll Then p(n).strength = p(n).strength - 1 ' attacker gets weaker because attack failed p(m).strength = p(m).strength + 2 ' defender gets stronger Else p(n).strength = p(n).strength + 1 ' attacker gains strength p(m).health = p(m).health - roll ' defender loses health End If Else ' roll for healing roll = rollBetween(1, 3) Debug.Print "player " & n & " rolled a " & roll & " for health" p(n).health = p(n).health + roll End If Debug.Print "statistics now: " & p(1).health & "," & p(1).strength & ";" & p(2).health & "," & p(2).strength End Sub Function winner(p() As player) Dim ii, h, w ' track player with higher health: h = 0 w = 0 For ii = LBound(p) To UBound(p) If p(ii).health > h Then w = ii h = p(ii).health End If Next ii winner = "Player " & w & " is the winner!"

1,279,656 | 0 | Cocoa/Objective-C: how much optimization should I do myself? <p>I recently found myself writing a piece of code that executed a Core Data fetch, then allocated two mutable arrays with the initial capacity being equal to the number of results returned from the fetch:</p> <pre><code>// Have some existing context, request, and error objects NSArray *results = [context executeFetchRequest:request error:&error]; NSMutableArray *firstArray = [[[NSMutableArray alloc] initWithCapacity:[results count]] autorelease]; NSMutableArray *secondArray = [[[NSMutableArray alloc] initWithCapacity:[results count]] autorelease];</code></pre> <p>I looked this over again once I'd written it, and something struck me as odd: I was calling <code>[results count]</code> twice. The resultset is potentially pretty large (hundreds, maybe a thousand, objects).</p> <p>My first instict was to break out <code>[results count]</code> into a separate NSUInteger, then use that integer for the capacity of each of the arrays. My question: is this kind of by-hand optimization necessary? Will the compiler recognize it's running <code>[results count]</code> twice and just hold the value without me having to explicitly specify that behavior? Or will it run the method twice - a potentially costly operation?</p> <p>In a similar vein, what other optimizations should programmers (especially iPhone programmers, where there's a limited amount of memory/processing power available) do by hand, as opposed to trusting the compiler?</p> |
35,760,975 | 0 | <p>The best way to coordinate multiple asynchronous operation is to use promises. So, if this were my code, I would change or wrap <code>saveImageToLocalTo()</code> and <code>Posts.insert()</code> to return promises and then use promise features for coordinating them. If you're going to be writing much node.js code, I'd suggest you immediately invest in learning how promises work and start using them for all async behavior.</p> <p>To solve your issue without promises, you'd have to implement a counter and keep track of when all the async operations are done:</p> <pre><code>var savedPath = []; var doneCnt = 0; for(i=0;i<n;i++) { savesaveImageToLocalTo(files[i], function(path) { ++doneCnt; savedPath.push(path); // if all the requests have finished now, then do the next steps if (doneCnt === n) { var post = req.body; post.images = savedPath; Posts.insert(postfunction(err, result) { res.send(err, result) }); } }); } </code></pre> <p>This code looks like it missing error handling since most async operations have a possibility of errors and can return an error code.</p> |

34,712,258 | 0 | <p>The add function returns a boolean which you can check to determine if the item was already in the Set. This is of course based on your needs and isn't a best practice. Its good to know that it will not remove an item that is already there so it can't be depended on to update the existing value with new information if you are defining equals based on surrogate keys from your database. This is opposite the way Maps work as a map will return any existing value and replace it with the new value.</p> |

12,757,460 | 0 | <p>When you run <code>git push heroku master</code> 'heroku' identifies the remote repository you are pushing to. In your case 'heroku' seems to be a reference to your production server. Similarly you probably have an 'origin' remote pointing to github.</p> <p>If you list your git remotes you'll probably see something like this:</p> <pre><code>> git remote -v heroku [email protected]:heroku_app_name.git (fetch) heroku [email protected]:heroku_app_name.git (push) origin [email protected]:your_github_org/repo_name.git (fetch) origin [email protected]:your_github_org/repo_name.git (push) </code></pre> <p>To push to a different heroku app you can just add that app as a new git remote.</p> <pre><code>git remote add heroku-staging [email protected]:heroku_staging_app.git </code></pre> <p>Now you should be able to push to either remote as needed.</p> <pre><code>git push origin master //push to github git push heroku-staging //deploy to staging git push heroku master //deploy to production </code></pre> <p>In general I suggest that you should not be pushing to heroku manually. Hopefully you can have a continuous integration server watch github, run tests whenever you push changes, and deploy to staging only when your automated tests pass. You can then have a manually triggered CI task which pushes whichever commit is currently on staging to production as well (or even automate production deploys as well).</p> <p>You can perform the same configuration using the <code>heroku</code> command line. That also gives you a good way to manage environment variables and other settings on both of your heroku apps: <a href="https://devcenter.heroku.com/articles/multiple-environments">https://devcenter.heroku.com/articles/multiple-environments</a></p> |

4,512,892 | 0 | <p>Have you tried turning <code>Viewstate</code> off in your <code>UserControl</code>? If you're building the markup using a <code>StringBuilder</code>, then there will not be any <code>Viewstate</code> transferred back and forth for any of that markup. If you're using default ASP web controls, they will default to having <code>Viewstate</code>, which will be transferred back and forth during pageload and postbacks, and could be quite large depending on what web controls are used in the UserControl and repeated 50 to 100 times.</p> <p>Edit: If <code>Viewstate</code> is not the problem, have you verified that the markup generated by the <code>UserControl</code> is the same or reasonably equivalent to the markup you're generating in the <code>StringBuilder</code>?</p> <p>Another critical thing to do is to benchmark server and client times. If the markup is different, the client rendering times may change noticably. If the server and client times are the same (or insignificantly different) then you need to look at sizes of the server output and transfer times.</p> |

One is killed and the other one lives on happily)</p> <p>Best solution is to ask your DBA (or if you have access to your oracle instalation, you can google and then get them yourself, it's not sou complicated) for trace file(this file is mentioned in exception of killed session, so search your alert log), there will be deadlock graph. (just fulltext trace file for DEADLOCK)</p> <p>Just look here for exact information how to look into your trace file. <a href="http://www.oracle-base.com/articles/misc/deadlocks.php" rel="nofollow">LINK</a></p> |
