Although they might not work the same under the hood, you can still put your application-wide global setting inside this file applications/yourapp/models/0_whatever_name.py Content in this file will be defined before (each) request reaches your app. Or you can simply append your app-wide global definitions into applications/yourapp/models/db.py By default it already contains lots of settings for this app.

I understand there is no such a thing like setting.py in Django for web2py . But is there a good place for these global setting for web2py ? I would like to put things like secret key, global constant and others.

I know we can use try and except function to catch the error. But everyday I monitor the sentry, the system always get an exception in any views. As usual I put try and except to catch the errors in the views. My question is. Is it possible to catch all the errors from any views in just one function? Then the user will redirect to another page. Where is the best place to do this? I'm thinking about middleware but I don't have knowledge about it.

I'm working on a Heroku app built in Python, and I can't find a recommended way to add a step to deployment for concatenating/processing/minifying JavaScript and CSS assets. For example, I might like to use tools like r.js or less. I've seen something called "collectstatic" that Heroku knows to run for Django apps, but my application is using web.py, not Django. One less-than-perfect approach would be to use these tools locally, on my development machine, to produce combined/compressed static assets. I could then check those compiled files into the git repository and push them to Heroku. Is there any support for this kind of step built in to Heroku? What is the best way of handling javascript/css files for Heroku web apps in Python?

You can't (easily) "get an instance of a running program" from outside. You can certainly instrument your program so that it communicates its statistics somehow, eg via a socket, or as an even lower-tech solution you could get it to store the relevant data periodically in a file on disk or in a database, which your web app could read.

Suppose a python program is running. Say the object of an Class in that program can give you some stats. So if i have to develop a web UI to display the stats, how do i get the instance of that class which is running[as an separate desktop app] and display the stats in web, which I would be using web2py or django.

uWSGI+gevent is a solid combo, while there is currently no-way to run uWSGI with the tornado api (and as uWSGI dropped support in 1.9 for callback based approach, i think that we will never see that combo working). The problem you need to solve before starting working with gevent, is ensuring that all of your pieces are gevent friendly (redis and celery are ok, you need to check your database adapter). After that simply add --gevent to your uWSGI instance, where is the maximum number of concurrent requests per worker.

why? because I have a django project that capture data from user and consume many webservices displaying the results to the user in order to compare information, something like aggregators websites who search flights tickets via airlines webservices and show the result in real time in order to compare tickets. nowaday im doing this in a "waiting page", where celery hits webservices while jquery is asking every 5 seconds if all results are ready, so when ready redirect to the results page. what I want to do is not to use this "waiting page", I want to feed the results page in real time as the results are comming, and I want to make it following the best practices, I mean I dont want to jquery get the results each X seconds to feed the table. I think some coroutine-based python library can help me with this, but I want to learn more about your experience first and see some examples, I am confused because this part of the project was designed to run asynchronously, I mean, consuming webservices with celery-chords, but not designed for dispatching the information in real time through the app server. actual architecture: python 2.7, django 1.3, postgresql 9, celery 3 + redis, uwsgi, nginx, all hosted on aws. thank you in advance.

I don't know about uWSGI+gevent, but you can use tornado with uWSGI. Tornado basically gives you an inbuilt WSGI support in tornado.wsgi.WSGIContainer module to make it compactable with other WSGI servers like uWSGI and gunicorn.But it depends on your use and I think it's not a good idea to use an Asynchronous framework with a synchronous server(like uWSGI). Tornado has this warning for this. WSGI is a synchronous interface, while Tornado’s concurrency model is based on single-threaded asynchronous execution. This means that running a WSGI app with Tornado’s WSGIContainer is less scalable than running the same app in a multi-threaded WSGI server like gunicorn or uwsgi. Use WSGIContainer only when there are benefits to combining Tornado and WSGI in the same process that outweigh the reduced scalability.

We have developed a web based application, with user login etc, and we developed a python application that have to get some data on this page. Is there any way to communicate python and system default browser ? Our main goal is to open a webpage, with system browser, and get the HTML source code from it ? We tried with python webbrowser, opened web page succesfully, but could not get source code, and tried with urllib2, in that case, i think we have to use system default browser's cookie etc, and i dont want to this, because of security.

Let's say we have two apps in a project: app1 and app2. Both have South migrations and in this particular case, migration app1.0002_something depends on app2.0001_initial. Everything is nice and fine until you decide that app2 is obsolete and should be deleted (since its utility has been put into app3 and app4 a long time ago). And here lies the problem: after removing app2 from INSTALLED_APPS ./manage.py migrate returns south.exceptions.DependsOnUnmigratedApplication: Migration 'app1:0002_something' depends on unmigrated application 'app2'. In this case, I'd probably "reset" the migrations of app1 and go on coding, however, I don't see how I can avoid this situation in the future short of not using dependencies at all. So the questions are: How can I resolve this situation more gracefully than "resetting" migration history? How do I prevent this situation from happening and still be able to delete obsolete apps?

Any answer to this question is open for discussion. That said, views are just Python classes, so you could overwrite any method to customize things accordingly. It is also perfectly legit to create an extra method on your class to handle data processing.

I'm currently trying to get into "Class Based Views" with Django 1.5. From the design perspective i wonder where to put the logic to process data comming from a form in a simple FormView. I know that all form validation code comes into the method form_valid(). But where to put things which processes data of the form. I read that its somehow inappropriate to put too much logic into the form_valid() method. There are the get(), post(), get_context_data(), head(), etc. methods... which should I use in which case?

Form validation, data cleaning, etc goes with the form class in the clean methods Processing of a valid form should go in an overridden form_valid method That's it! If your use-case is more complicated you can call out to other methods of your creation from form_valid...

I'm planning to build a Django app to generate and later server static pages (probably stored on S3). When users visit a url like mysite.com/static-pages/12345 the static file in my S3 bucket named 12345.html should be served. That static file might be the static html page of a blog page my site has generated for the user, for example. This is different from including static resources like CSS/Javascript files on a page that is rendered as a Django template since I already know how to use Django templates and SQL databases - what's unfamiliar to me is that my "data" is now a file on S3 rather than an entry in a database AND that I don't actually need to use a template. How exactly can I retrieve the requested data (i.e. a static page) and return it to the user? I'd like to minimize performance penalties within reason, although of course it would be fastest if users directly requested their static pages from S3 (I don't want them to do this)". A few additional questions: I've read elsewhere about a django flatpages app which stores html pages in a database, but it seems like static html pages are best stored on a filesystem like S3, no? Is there a way to have the request come in to my Django application and have S3 serve the file directly while making it appear to have come from my application (i.e. the browser url still says mysite.com/static-pages/12345, but the page did not go through my Django server)? Thanks very much!

If you need to unit test the code separate from the View then you should defiantly separate it into another module or class. As there seems to be three parts to your business logic then I would say starting by splitting the view into three functions of a module seems a good place to start.

Please help me how to solve following task in "pythonic" way: There are several model classes, which are mapped to the DB with the help of SQLAlchemy. There is a Flask view, which handles the "POST" request. The business logic of this method contains complex logic which includes: Getting input parameters from input JSON Validation Creation of several different models and the saving to database. Is it a good idea to leave this logic in the "View"? Or it would be much better to separate this this logic into different modules or classes, for instance by introducing business logic class?

So, in order to avoid the "no one best answer" problem, I'm going to ask, not for the best way, but the standard or most common way to handle sessions when using the Tornado framework. That is, if we're not using 3rd party authentication (OAuth, etc.), but rather we have want to have our own Users table with secure cookies in the browser but most of the session info stored on the server, what is the most common way of doing this? I have seen some people using Redis, some people using their normal database (MySQL or Postgres or whatever), some people using memcached. The application I'm working on won't have millions of users at a time, or probably even thousands. It will need to eventually get some moderately complex authorization scheme, though. What I'm looking for is to make sure we don't do something "weird" that goes down a different path than the general Tornado community, since authentication and authorization, while it is something we need, isn't something that is at the core of our product and so isn't where we should be differentiating ourselves. So, we're looking for what most people (who use Tornado) are doing in this respect, hence I think it's a question with (in theory) an objectively true answer. The ideal answer would point to example code, of course.

python,tornado

Here's how it seems other micro frameworks handle sessions (CherryPy, Flask for example): Create a table holding session_id and whatever other fields you'll want to track on a per session basis. Some frameworks will allow you to just store this info in a file on a per user basis, or will just store things directly in memory. If your application is small enough, you may consider those options as well, but a database should be simpler to implement on your own. When a request is received (RequestHandler initialize() function I think?) and there is no session_id cookie, set a secure session-id using a random generator. I don't have much experience with Tornado, but it looks like setting a secure cookie should be useful for this. Store that session_id and associated info in your session table. Note that EVERY user will have a session, even those not logged in. When a user logs in, you'll want to attach their status as logged in (and their username/user_id, etc) to their session. In your RequestHandler initialize function, if there is a session_id cookie, read in what ever session info you need from the DB and perhaps create your own Session object to populate and store as a member variable of that request handler. Keep in mind sessions should expire after a certain amount of inactivity, so you'll want to check for that as well. If you want a "remember me" type log in situation, you'll have to use a secure cookie to signal that (read up on this at OWASP to make sure it's as secure as possible, thought again it looks like Tornado's secure_cookie might help with that), and upon receiving a timed out session you can re-authenticate a new user by creating a new session and transferring whatever associated info into it from the old one.

The key issue with sessions is not where to store them, is to how to expire them intelligently. Regardless of where sessions are stored, as long as the number of stored sessions is reasonable (i.e. only active sessions plus some surplus are stored), all this data is going to fit in RAM and be served fast. If there is a lot of old junk you may expect unpredictable delays (the need to hit the disk to load the session).

Your students' code is transfered to the webserver via a simple form submit. Then when your server produces an HTML response it is rendered in the iframe. No javascript is needed. KISS!

Hi all this is my first post as I have exhausted google and am asking for a little bit of help. I'm a school teacher and I'm creating an ELearning website for my school, at present I'm attempting to create a code window where my students can input some python syntax and onlick the code is converted and shown in the adjacent window. Very similar to what is used in W3schools for its examples and various elearning websites. Does anybody have any knowledge as to where I should start or have any links about creating this? I would probably go along the lines of when the 'submit code' button is pressed, a javascript object is created of the user input code, then rendered into the adjacent result box using some sort of ajax.

How can I generate a random url of a certain length every time a page is created?

I am new to Python and programming but here a few issues I can see with 'random string' idea: You will most probably end up generating same string over and over if you are using shorter strings. On the other side if you are using longer strings, the changes of getting the same string is less. However you will want to watch out for duplicates on either case. Therefore my suggestion is to make some estimations of how many urls you will need, and use an optimal string length for it. Easiest way is to keep these urls in a list, and use a simple if check before registering new ones: if new_url in url_list: generate_new_url() else: url_list.append(new_url) However it also sounds like you will want to employ a database to permanently store your urls. In most sql based databases you can setup your url column to be 'unique'; therefore database stops you from having dublicate urls. I am not sure but with the database you can probably do this: try: #insert value to database except: generate_new_url()

In my python/pyramid app, I let users generate html pages which are stored in an amazon s3 bucket. I want each page to have a separate path like www.domain.com/2cxj4kl. I have figured out how to generate the random string to put in the url, but I am more concerned with duplicates. how can I check each of these strings against a list of existing strings so that nothing is overwritten? Can I just put each string in a dictionary or array and check the ever growing array/dict each time a new one is created? Are there issues with continuing to grow such an object, and will it permanently exist in the app memory somehow? How can I do this?

I am calling a Python script from my Java code. This is the code : import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class JavaRunCommand { public static void main(String args[]) throws IOException { // set up the command and parameter String pythonScriptPath = "my-path"; String[] cmd = new String[2]; cmd[0] = "python2.6"; cmd[1] = pythonScriptPath; // create runtime to execute external command Runtime rt = Runtime.getRuntime(); Process pr = rt.exec(cmd); // retrieve output from python script BufferedReader bfr = new BufferedReader(new InputStreamReader( pr.getInputStream())); String line = ""; while ((line = bfr.readLine()) != null) { // display each output line form python script System.out.println(line); } } } python.py which works import os from stat import * c = 5 print c python.py which does not works import MySQLdb import os from stat import * c = 5 print c # some database code down So, I am at a critical stage where I have a deadline for my startup and I have to show my MVP project to the client and I was thinking of calling Python script like this. It works when I am printing anything without dB connection and MySQLdb library. But when I include them, it does not run the python script. Whats wrong here. Isnt it suppose to run the process handling all the inputs. I have MySQLdb installed and the script runs without the java code. I know this is not the best way to solve the issue. But to show something to the client I need this thing working. Any suggestions ?

I think there are issues with Celery as a background task on Heroku. We tried to create such tasks and they take all memory after running for about 20 minutes, even with DEBUG=False on Redis or RabbitMQ. Worse still, the memory is NEVER released: every time we have to restart the worker. The same code runs flawlessly on bare Linux or on Mac with Foreman. It happens with very simple tasks, like reading a text file in a loop, writing to a Django model.

I was finally getting to the point where I had some free time and wanted to add Celery to my Python/Flask project on Heroku. However, almost all mentions of Celery from the Heroku docs are gone. There used to be article with a tutotial in the "Getting started with Django", but it's gone. Will "just doing it" myself work? What's a good AMQP addon to use as backend on Heroku?

The created project should have a static folder. Put all resources (images, ...) in there. Then, in your HTML template, you can reference STATIC_ROOT and add the resource path (relative to the static folder)

I've looked through countless answers and questions trying to find a single definitive guide or way to do this, but it seems that everyone has a different way. Can someone please just explain to me how to serve static files in templates? Assuming I've just created a brand new project with Django 1.4, what all do I need to do to be able to render images? Where should I put the media and static folders?

Put your static files into <app>/static or add an absolute path to STATICFILES_DIRS Configure your web server (you should not serve static files with Django) to serve files in STATIC_ROOT Point STATIC_URL to the base URL the web server serves Run ./manage.py collectstatic Be sure to use RequestContext in your render calls and {{ STATIC_URL }} to prefix paths Coffee and pat yourself on the back A little bit more about running a web server in front of Django. Django is practically an application server. It has not been designed to be any good in serving static files. That is why it actively refuses to do that when DEBUG=False. Also, the Django development server should not be used for production. This means that there should be something in front of Django at all times. It may be a WSGI server such as gunicorn or a 'real' web server such as nginx or Apache. If you are running a reverse proxy (such as nginx or Apache) you can bind /static to a path in the filesystem and the rest of the traffic to pass through to Django. That means your STATIC_URL can be a relative path. Otherwise you will need to use an absolute URL.

Quick writing to log file after http request

php,python,performance,logging

One possible option what I can think of is a separate logging process. So that your web.py can be shielded for performance issue. This is classical way of handling logging module. You can use IPC or any other bus communication infrastructure. With this you will be able to address two issues - Logging will not be a huge bottle neck for high capacity call flows. A separate module can ensure/provide switch off/on facility. As such there would not be any huge/significant process memory usage. However, you should bear in mind below points - You need be sure that logging is restricted to just logging. It must not be a data store for business processing. Else you may have many synchronization problem in your business logic. The logging process (here I mean actual Unix process) will become critical and slightly complex (i.e you may have to handle a form of IPC). HTH!

I currently finished building a Web server who's main responsibility is to simply take the contents of the body data in each http post request and write it to a log file. The contents of the post data is obfuscated when received. So i'm un obfuscating the post data and writing it to a log file on the server. The contents after obfuscated is a series of random key value pairs that differ between every request. It is not fixed data. The server is running Linux with 2.6+ kernel. Server is configured to handle heavy traffic (open files limit 32k, etc). The application is written in Python using web.py framework. The http server is Gunicorn behind Nginx. After using Apache Benchmark to do some load testing, I noticed that it can handle up to about 600-700 requests per second without any log writing issues. Linux natively does a good job at buffering. Problems start to occur when more than this many requests per second attempt to write to the same file at same moment. Data will not get written and information will be lost. I know that "the writing directly to a file" design might not have been the right solution from the get go. So i'm wondering if anyone can propose a solution that I can implement quickly without altering too much infrastructure and code that can overcome this problem? I have read about in memory storage like Redis, but I have realized that if data is sitting in memory during server failure then that data is lost. I have read in the docs that redis can be configured as a persistent store, there just needs to be enough memory on the server for Redis to do it. This solution would mean that I would have to write a script that would dump the data from Redis (memory) to the Log file at a certain interval. I am wondering if there is even a quicker solution? Any help would be greatly appreciated!

To add to Dan's correct answer, remember ndb and the older db are just APIs so you can seamlessly begin switching to ndb without worrying about schema changes etc.. You're question asks about switching from datastore to NDB, but you're not switching from the datastore as NDB still uses the datastore. Make sense?

From what I have heard, it is better to move to NDB from Datastore. I would be doing that eventually since I hope my website will be performance intensive. The question is when. My project is in its early stages. Is it better to start in NDB itself? Does NDB take care of Memcache also. So I don't need to have an explict Memcache layer?

I think you're thinking about this problem backwards. Node.js lets you run browser Javascript without a browser. You won't find it useful in your Python programming. You're better off, if you want to stick with Python, using a framework such as Pyjamas to write Javascript with Python or another framework such as Flask or Twisted to integrate the Javascript with Python.

I am a website development senior at my university, but I have not used Python before. I understand both ActionScript and Javascript and I think their logic might be beneficial for learning Python. For the web languages I am familiar with writing I use Sublime2, Dreamweaver, or Flash to code them. So my questions are: Which program do I use to code Python? How do I use the code created in Python to work on Android phones?

Python/Django - Avoid saving passwords in source code

python,django,security,version-control,django-settings

Having something like this in your settings.py: db_user = 'my_db_user' db_password = 'my_db_password' Hard codes valuable information in your code and does pose a security risk. An alternative is to store your valuable information (Api keys, database passwords etc.) on your local machine as environment variables. E.g. on linux you could add: export DB_USER = "my_db_user" export DB_PASS = "my_db_password" to your .bash_profile. Or there is usually an option with your hosting provider to set environment variables e.g. with AWS elastic beanstalk you can add env variables under your configuration on console. Then to retrieve your information import os: import os db_user = os.environ.get['DB_USER'] db_password = os.environ.get['DB_PASS']

I use Python and Django to create web applications, which we store in source control. The way Django is normally set up, the passwords are in plain text within the settings.py file. Storing my password in plain text would open me up to a number of security problems, particularly because this is an open source project and my source code would be version controlled (through git, on Github, for the entire world to see!) The question is, what would be the best practice for securely writing a settings.py file in a a Django/Python development environment?

On my site I'm using simple text overlay. Inputs come from textboxes and then javascript makes an AJAX call with the inputs that are then processed in the backend by PIL (Python Imaging Library). Thing is, I'm not happy about the quality of PIL's text overlays - it's not possible to do a nice looking stroke (e.g. white font color + black stroke) and I'm thinking about switching to a different solution than PIL. I want to stay with Python though. What would you recommend for image processing in Python? Which library offers the best quality? Thanks! Best, Tom

I possibly ran into a similar problem on my pyramid app. I'm using TinyMCE and had placed the files in the static folder. Everything worked on my dev server, but moved to test and prod and static .html files related to TinyMCE couldn't be found. My web host had me add a symlink basically I think hardcoding to the server software (nginix in this case) the web address to my static HTML to the server path and that worked. I'll have to check out the mimetypes thing, though, too.

Is a Python Decorator the same as Java annotation, or Java with Aspects?

java,python,python-decorators,java-annotations

This is a very valid question that anyone dabbling in both these languages simultaneously, can get. I have spent some time on python myself, and have recently been getting myself up to speed with Java and here's my take on this comparison. Java annotations are - just that: annotations. They are markers; containers of additional metadata about the underlying object they are marking/annotating. Their mere presence doesn't change execution flow of the underlying, or doesn't add encapsulation/wrapper of some sort on top of the underlying. So how do they help? They are read and processed by - Annotation Processors. The metadata they contain can be used by custom-written annotation processors to add some auxiliary functionality that makes lives easier; BUT, and again, they NEITHER alter execution flow of an underlying, NOR wrap around them. The stress on "not altering execution flow" will be clear to someone who has used python decorators. Python decorators, while being similar to Java annotations in look and feel, are quite different under the hood. They take the underlying and wrap themselves around it in any which way, as desired by the user, possibly even completely avoiding running the underlying itself as well, if one chooses to do so. They take the underlying, wrap themselves around it, and replace the underlying with the wrapped ones. They are effectively 'proxying' the underlying! Now that is quite similar to how Aspects work in Java! Aspects per se are quite evolved in terms of their mechanism and flexibility. But in essence what they do is - take the 'advised' method (I am talking in spring AOP nomenclature, and not sure if it applies to AspectJ as well), wrap functionality around them, along with the predicates and the likes, and 'proxy' the 'advised' method with the wrapped one. Please note these musings are at a very abstract and conceptual level, to help get the big picture. As you start delving deeper, all these concepts - decorators, annotations, aspects - have quite an involving scope. But at an abstract level, they are very much comparable. TLDR In terms of look and feel, python decorators can be considered similar to Java annotations, but under the hood, they work very very similar to the way Aspects work in Java.

There is no 'clean' way to do this. You must relay on CURL or file_get_context() with context options in order to simply get data from URL, and, in order to notify you when content of URL is changed, you must store in database snapshots of page you are listening. Lately you are comparing new version of crawled content with earlier created snapshot and, if change in significant parts of DOM are detected, that should be trigger for your mail notifier function.

Is there any clean way to do this? I could set up a program and run it on a server somewhere and have it just poll ebay.com every couple of minutes or seconds indefinitely but I feel like there should be a better way. This method could get dicey too if I wanted to monitor a variety of pages for updates.

But LaTeX files can take a while to compile sometimes if they're long, so I'm starting to think this isn't the best way to do it. What's the standard way of doing something like this? It must be a pretty common problem.

You need to create different page trees per language. Every page has only one template. Use {% trans %} and {% blocktrans %} for translating string in it. Or {% if request.LANGUAGE == "en" %}. If the templates really differ that much: don't add other languages to pages... but create different page trees with only one language.

If you are referring to the Working-copy-support option: Files are excluded from the possibility to be checked-out. Probably exactly because of the reasons you are rising. Versioning attached files is easily blasting the DB because every file would be kept in the DB and thus (to answer your question) the object's size would be a sum of all of them. Also the standard-versioning-history is not applied to files.

I don't know what manage.py tasks is, must be from some extension you have installed. However what you are asking doesn't make much sense. An app, at a minumum, has a models.py file, which presumably your templates folder doesn't have. But there is of course no reason at all to treat your templates folder as an app. Put the folder into TEMPLATE_DIRS instead.

So in short, is it possible to load an intranet page from an internet-page that has no access to said intranet.

Of course you can load it in an iframe, you don't need access to the page from the internet for that - the client needs it. Yet, the intranet application might request not to be viewed in a frame.

Let's say my app is served at the domain www.example.com. How (where?) should I specify this in the Pyramid configuration file so that functions like request.route_url would automatically pick it and generate the correct URL. (I think [server:main] is not the place for this)

I know I may be considered a little off the wall here but there is another option. We know that from time to time there is a bug that happens on transit.We know that there is not much we can do right now to stop the problem. If you are only providing the API then stop reading however if you write the client too, keep going. The error is a known case, and known cause. The result of an empty return value means that something went wrong. However the value is available and was fetched, calculated, whatever... My instinct as a developer would be to treat an empty result as an HTTP error and request the data be resent. You could then track the resend requests and see how often this happens. I would suggest (although you strike me as the kind of developer to think of this too) that you count the requests and set a sane value for responding "network error" to the user. My instinct would be to retry right away and then to wait a little while before retrying some more. From what you describe the first retry would probably pick up the data properly. Of course this could mean keeping older requests hanging about in cache for a few minutes or running the request a second time depending on what seemed most appropriate. This would also route around any number of other point-to-point networking errors and leave the app far more robust even in the face of connectivity problems. I know our instinct as developers is to fix the known fault but sometimes it is better to work towards a system that is able to operate despite faults. That said it never hurts to log errors and problems and try to fix them anyway.

I am running a Flask/Gunicorn Python app on a Heroku Cedar dyno. The app returns JSON responses to its clients (it's an API server, really). Once in a while clients get 0-byte responses. It's not me returning them, however. Here is a snippet of my app's log: Mar 14 13:13:31 d.0b1adf0a-0597-4f5c-8901-dfe7cda9bce0 app[web.1] [2013-03-14 13:13:31 UTC] 10.104.41.136 apisrv - api_get_credits_balance(): session_token=[MASKED] The first line above is me starting to handle the request.

Mar 14 13:13:31 d.0b1adf0a-0597-4f5c-8901-dfe7cda9bce0 app[web.1] "10.104.41.136 - - [14/Mar/2013:13:13:31] "POST /get_credits_balance?session_token=MASKED HTTP/1.1" 200 22 "-" "Appcelerator Titanium/3.0.0.GA (iPhone/6.1.2; iPhone OS; en_US;)" The third line is Gnicorn's, where you can see the Gunicorn got the 200 status and 22 bytes HTTP body ("200 22"). However, the client got 0 bytes. Here is the Heroku router log: Mar 14 13:13:30 d.0b1adf0a-0597-4f5c-8901-dfe7cda9bce0 heroku[router] at=info method=POST path=/get_credits_balance?session_token=MASKED host=matchspot-apisrv.herokuapp.com fwd="66.87.116.128" dyno=web.1 queue=0 wait=0ms connect=1ms service=19ms status=200 bytes=0 Why does Gunicorn return 22 bytes, but Heroku sees 0, and indeed passes back 0 bytes to the client? Is this a Heroku bug?

No, there's no generally applicable way of doing that for Python. There are some heuristics for simple modules, but they're going to fail miserably. In the specific case of NumPy you'd have to first find out which parts of its underlying C and Fortran code are needed and which aren't, which is a pretty difficult problem in its own right. Even if you can solve that, the fact that NumPy also uses __import__ in several places, including in compiled extension modules, makes it nearly impossible to determine which parts of the code are going to be imported.

I've been reading up on SimpleDB and one downfall (for me) is the 1kb max per attribute limit. I do a lot of RSS feed processing and I was hoping to store feed data in SimpleDB (articles) and from what I've read the best way to do this is to shard the article across several attributes. The typical article is < 30kb of plain text. I'm currently storing article data in DynamoDB (gzip compressed) without any issues, but the cost is fairly high. Was hoping to migrate to SimpleDB for cheaper storage with still fast retrievals. I do archive a json copy of all rss articles on S3 as well (many years of mysql headaches make me wary of db's). Does anyone know to shard a string into < 1kb pieces? I'm assuming an identifier would need to be appended to each chunk for order of reassembly. Any thoughts would be much appreciated!

Persistent in-memory Python object for nginx/uwsgi server

"python in-memory data will NOT be persisted across all requests to my knowledge, unless I'm terribly mistaken." you are mistaken. the whole point of using uwsgi over, say, the CGI mechanism is to persist data across threads and save the overhead of initialization for each call. you must set processes = 1 in your .ini file, or, depending on how uwsgi is configured, it might launch more than 1 worker process on your behalf. log the env and look for 'wsgi.multiprocess': False and 'wsgi.multithread': True, and all uwsgi.core threads for the single worker should show the same data. you can also see how many worker processes, and "core" threads under each, you have by using the built-in stats-server. that's why uwsgi provides lock and unlock functions for manipulating data stores by multiple threads. you can easily test this by adding a /status route in your app that just dumps a json representation of your global data object, and view it every so often after actions that update the store.

I doubt this is even possible, but here is the problem and proposed solution (the feasibility of the proposed solution is the object of this question): I have some "global data" that needs to be available for all requests. I'm persisting this data to Riak and using Redis as a caching layer for access speed (for now...). The data is split into about 30 logical chunks, each about 8 KB. Each request is required to read 4 of these 8KB chunks, resulting in 32KB of data read in from Redis or Riak. This is in ADDITION to any request-specific data which would also need to be read (which is quite a bit). Assuming even 3000 requests per second (this isn't a live server so I don't have real numbers, but 3000ps is a reasonable assumption, could be more), this means 96KBps of transfer from Redis or Riak in ADDITION to the already not-insignificant other calls being made from the application logic. Also, Python is parsing the JSON of these 8KB objects 3000 times every second. All of this - especially Python having to repeatedly deserialize the data - seems like an utter waste, and a perfectly elegant solution would be to just have the deserialized data cached in an in-memory native object in Python, which I can refresh periodically as and when all this "static" data becomes stale. Once in a few minutes (or hours), instead of 3000 times per second. But I don't know if this is even possible. You'd realistically need an "always running" application for it to cache any data in its memory. And I know this is not the case in the nginx+uwsgi+python combination (versus something like node) - python in-memory data will NOT be persisted across all requests to my knowledge, unless I'm terribly mistaken. Unfortunately this is a system I have "inherited" and therefore can't make too many changes in terms of the base technology, nor am I knowledgeable enough of how the nginx+uwsgi+python combination works in terms of starting up Python processes and persisting Python in-memory data - which means I COULD be terribly mistaken with my assumption above! So, direct advice on whether this solution would work + references to material that could help me understand how the nginx+uwsgi+python would work in terms of starting new processes and memory allocation, would help greatly. P.S: Have gone through some of the documentation for nginx, uwsgi etc but haven't fully understood the ramifications per my use-case yet. Hope to make some progress on that going forward now If the in-memory thing COULD work out, I would chuck Redis, since I'm caching ONLY the static data I mentioned above, in it. This makes an in-process persistent in-memory Python cache even more attractive for me, reducing one moving part in the system and at least FOUR network round-trips per request.

You said nothing about writing this data back, is it static? In this case, the solution is every simple, and I have no clue what is up with all the "it's not feasible" responses. Uwsgi workers are always-running applications. So data absolutely gets persisted between requests. All you need to do is store stuff in a global variable, that is it. And remember it's per-worker, and workers do restart from time to time, so you need proper loading/invalidation strategies. If the data is updated very rarely (rarely enough to restart the server when it does), you can save even more. Just create the objects during app construction. This way, they will be created exactly once, and then all the workers will fork off the master, and reuse the same data. Of course, it's copy-on-write, so if you update it, you will lose the memory benefits (same thing will happen if python decides to compact its memory during a gc run, so it's not super predictable).

No, there really isn't any way to do this without putting some sort of service between the people clicking on the links and the S3 objects. The reason is that access to the S3 content is determined by your AWS access_key and secret_key. There is no way to "login" with these credentials and logging into the AWS web console uses a different set of credentials that are only useful for the console. It does not authenticate you with the S3 service.

I can't seem to find a way to generate a link that works to only people that authenticated. I can create a link using the generate_url method, but then anybody who clicks on that link can access the file. Any other of creating the url, creates a link that doesn't work even if I'm logged in (Get an XML with access denied). Anybody knows of a way of doing this? Preferably permanent links, but I can do with only temporary links that expires after given time Thanks, Ophir

I guess you will have to create a list of all known file extensions that you do NOT want, and then scan the content of the http response, checking with "if substring not in nono-list:" The problem is all href's ending with TLDs, forwardslashes, url-delivered variables and so on, so i think it would be easier to check for stuff you know you dont want.

Before trying to give you an idea... I must say I would try first your database option. Databases are made just for that and, even if your DB gets really big, this should not do the crawling significantly slow. And one lesson I have learned: "First do the dumb implementation. After that, you try to optimize." Most of times when you optimize first, you just optimize the wrong part. But, if you really want another idea... Scrapy's default is not to crawl the same url two times. So, before start the crawling you can put the already scraped urls (3 days before) in the list that Scrapy uses to know which urls were already visited. (I don't know how to do that.) Or, simpler, in your item parser you can just check if the url was already scraped and return None or scrape the new item accordingly.

Please help me solve following case: Imagine a typical classified category page. A page with list of items. When you click on items you land on internal pages.Now currently my crawler scrapes all these URLs, further scrapes these urls to get details of the item, check to see if the initial seed URL as any next page. If it has, it goes to the next page and do the same. I am storing these items in a sql database. Let say 3 days later, there are new itmes in the Seed URL and I want to scrap only new items. Possible solutions are: At the time of scraping each item, I check in the database to see if the URL is already scraped. If it has, I simply ask Scrapy to stop crawling further. Problem : I don't want to query database each time. My database is going to be really large and it will eventually make crawling super slow. I try to store last scraped URL and pass it on in the beginning, and the moment it finds this last_scraped_url it simply stops the crawler. Not possible, given the asynchronous nature of crawling URLs are not scraped in the same order they are received from seed URLs. ( I tried all methods to make it in orderly fashion - but that's not possible at all ) Can anybody suggest any other ideas ? I have been struggling over it for past three days. Appreciate your replies.

Move data from Raspberry pi to a synology diskstation to present in a webpage

I'm not experiment on this topic but what I would do is setup a database in between (on the Synology rather than on the Raspberry Pi). Let's call your Synology server, and Raspberry Pi a sensor client. I would host a database on the server, and push the from the sensor client. The data would be pushed either using an API through webservices or a more low level if you need it faster (some code needed on server side for this) or, since the client computer is under your control, it could directly push in the database. Your concrete choice between database, webservice or other API depends on: How much data have to be pushed? How fast data have to pushed? How much do you trust your network? How much do you trust your sensor client? I've never used it but I suggest you use SQLAlchemy for connecting to the database (from both side). If in some use case the remote server can be down, the sensor client would store sensor data in some local file and push them when the server come back online.

I'm looking for ideas, on how to display sensor data in a webpage, hosted by a Synology Diskstation, where the data comes from sensors connected to a Raspberry pi. This is going to be implemented in Python. I have put together the sensors, and have these connected to the Raspberry. I have also the Python code, so I can read the sensors. I have a webpage up and running on the Diskstation using Python. But how do I get the data from the rasp to the Diskstation. The reading is just done, when the webpage is displayed. Guess some kind of WebServices on the Rasp ? I have looked at Pyro4, but doesn't look like it can be installed at the Diskstation. And I would prefer not to install a whole WebServer Framework on the rasp. Do you have a suggestion ?

Sorry, you can't do that. You will need to re-authorize the user. I agree that it would be nice to incrementally add scopes, but you will still need to show an authorization page, so I think you won't gain much doing that.

What is the best way to add/expand/remove scopes when the application has an existing grant? Revoke and reauthorize?

your form will be more complicated than a simple ModelForm . maybe you could subclass ModelForm and populate a new DateTimeField for each DateTimeField in the model... as for the making of the query... it will be a work too. think about hardcode the extra DateField if you want to filter for only one Model

Store file on server for a short time period

15,587,348

python,webapp2,temporary-files

I would suggest using a client-created UUID on the server, and when the server stores it, send back an error (forcing a retry) to the client. Under most circumstances, the UUID will be completely unique and won't collide with anything already stored. If it does, the client can pick a new name and try again. If you want to make this slightly better, wait a random number of milliseconds between retries to reduce the likelihood of collisions being repeated. That'd be my approach to this specific, insecure, short-term storage problem. As for removal, I'd leave that in the responsibility of the server to remove them at intervals, basically checking to see if any file is greater than 5 minutes old and removing them. As long as in-process downloads leave the file open, it shouldn't interrupt. If you want to leave the client in control, you will not have an easy way to enforce deletion when the client is offline, so I'd suggest keeping a list of the files in date order and delete them: in a background thread as necessary if you expect to be running a long time at startup (which will require persisting these to disk) at shutdown (doesn't require persisting to disk) However, all of these mechanisms are prone to leaving unnecessary files on the server if you crash or lose the persistent information, so I'd still recommend making the deletion the responsibility of the server.

You're probably right, PostGIS/GeoDjango is probably overkill, but making your own Django app would not be too much trouble for your simple task. Django offers a lot in terms of templating, etc. and with the built in admin makes it pretty easy to enter single records. And GeoDjango is part of contrib, so you can always use it later if your project needs it.

For my app, I need to determine the nearest points to some other point and I am looking for a simple but relatively fast (in terms of performance) solution. I was thinking about using PostGIS and GeoDjango but I think my app is not really that "geographic" (I still don't really know what that means though). The geographic part (around 5 percent of the whole) is that I need to keep coordinates of objects (people and places) and then there is this task to find the nearest points. To put it simply, PostGIS and GeoDjango seems to be an overkill here. I was also thinking of django-haystack with SOLR or Elasticsearch because I am going to need a strong, strong text search capabilities and these engines have also these "geographic" features. But not sure about it either as I am afraid of core db <-> search engine db synchronisation and hardware requirements for these engines. At the moment I am more akin to use posgreSQL trigrams and some custom way to do that "find near points problem". Is there any good one?

On search screens, users can sort the results by clicking on a column header. Unfortunately, this doesn't work for all columns. It works fine for regular fields like name and price that are stored on the table itself. It also works for many-to-one fields by joining to the referenced table and using the default sort order for that table. What doesn't work is most functional fields and related fields. (Related fields are a type of functional field.) When you click on the column, it just ignores you. If you change the field definition to be stored in the database, then you can sort by it, but is that necessary? Is there any way to sort by a functional field without storing its values in the database?

This is answered, but to explain a little further - the local datastore, by default writes to the temporary file system on your computer. By default, the temporary file is emptied any time you restart the computer, hence your datastore is emptied. If you don't restart your computer, your datastore should remain.

lxml's transform methods allow you to profile a transformation, and obtain the results as an XML document which shows how many times a pattern/mode/named-template was used. It should be possible to then perform an XPath across the XSL files to obtain all the comparative patterns/modes/named-templates and compare the two lists to see which templates are most/least used.

I have javascript files in my static folder. Django finds and loads them perfectly fine, so I don't think there is anything wrong with my configuration of the static options. However, sometimes when I make a change to a .js file and save it, the Django template that uses it does NOT reflect those changes -- inspecting the javascript with the browser reveals the javascript BEFORE the last save. Restarting the server does nothing, though restarting my computer has sometimes solved the issue. I do not have any code that explicitly deals with caching. Has anyone ever experienced anything like this?

It is sent in the clear, then the server hashes it. You would need to use https to prevent eavesdropping.

When you login to django, does the password get hashed and then transmitted or is it transmitted in the clear and the server does the hashing? This is within the context of not using https.

How to access the file shared between different accessors?

Your best bet might be to ditch the use of a file and use sockets. The Java program generates and caches the output until a Python script is listening. The Python script then accepts the data, and handles it. Alternatively, you could use IPC signalling between the two processes, although this seems a lot more messy than sockets, IMHO. Otherwise, a .lock file seems like your best bet.

I have code written on Java which writes all data to the file and then I have python script which handles this data. They run completely separately and python script can be run by schedule but it also removing handled records from the file. The question is in implementation for the access to the file when java code from first process will try to write something and python code from second process will try to remove handled record? First thought was to have .lock file physically created when one of the processes updating the file but perhaps there are some other solutions to consider? Thank you.

Make sure that both the Java and Python methods close the file when they are done. One possibility is to convert your Python script to Jython. If both processes are running in the JVM then you should be able to use standard Java concurrency techniques to make sure you do not have both threads modifying the file simultaneously.

One mechanism would be to have the producer roll the file to a new name (maybe with HHMMSS suffix) every so often, and have the consumer only process the file once it has been rolled to the new name. Maybe every 5 minutes? Another mechanism would be to have the consumer roll the file itself and have the producer notice that the file has rolled and to re-open the original file name. So the consumer is always consuming from output.consume and the producer is always writing to output or something. Every time a line is written to the file, the producer makes sure that output exists. When a consumer is ready to read the file, he renames output to output.consume or something. The producer notices that the file output no longer exists so he reopens it for output. Once the output file is re-created the consumer can process the output.comsume file.

How do I install Mezzanine as a Django app?

If you are like me, you will find that the FAQ is sorely lacking in its description of how to get Mezzanine working as an app. So here is what I did (after a painful half day of hacking) to get it integrated (somewhat): Download the repo and copy it into your project Run setup.py for the package cd to the package and run the mezzanine command to create a new app (mezzanine-project <project name>), let's say you use the name blog as your <project_name>. In either the local_settings.py or settings.py file, set the DATABASES dict to use your project's database. Run the createdb command from the mezzanine manage.py file Now it's time to start the hack-fest: In your project's settings.py file, add blog to INSTALLED_APPS Add some configuration variables to settings.py that Mezzanine is expecting: PACKAGE_NAME_FILEBROWSER = "filebrowser_safe" PACKAGE_NAME_GRAPPELLI = "grappelli_safe" GRAPPELLI_INSTALLED = False ADMIN_REMOVAL = [] RATINGS_RANGE = range(1, 5) TESTING = False BLOG_SLUG = '' COMMENTS_UNAPPROVED_VISIBLE = True COMMENTS_REMOVED_VISIBLE = False COMMENTS_DEFAULT_APPROVED = True COMMENTS_NOTIFICATION_EMAILS = ",".join(ALL_EMAILS) COMMENT_FILTER = None Add some middleware that Mezzanine is expecting: ```` ... "mezzanine.core.request.CurrentRequestMiddleware", "mezzanine.core.middleware.RedirectFallbackMiddleware", "mezzanine.core.middleware.TemplateForDeviceMiddleware", "mezzanine.core.middleware.TemplateForHostMiddleware", "mezzanine.core.middleware.AdminLoginInterfaceSelectorMiddleware", "mezzanine.core.middleware.SitePermissionMiddleware", Uncomment the following if using any of the SSL settings: "mezzanine.core.middleware.SSLRedirectMiddleware", "mezzanine.pages.middleware.PageMiddleware", .... ```` Add some INSTALLED_APPS that Mezzanine is expecting: .... "mezzanine.boot", "mezzanine.conf", "mezzanine.core", "mezzanine.generic", "mezzanine.blog", "mezzanine.forms", "mezzanine.pages", "mezzanine.galleries", "mezzanine.twitter", .... Add references to the template folders of mezzanine to your TEMPLATE_DIRS tuple os.path.join(BASE_PARENT, '<path to mezzanine>/mezzanine/mezzanine'), os.path.join(BASE_PARENT, '<path to mezzanine>/mezzanine/mezzanine/blog/templates'), Finally, if your like me, you'll have to override some of the extends paths in the mezzanine templates, the most obvious being in "blog_post_list.html" which just extends base.html, instead you want it to extend the mezzanine specific base file. So go to that file and replace the {% extends "base.html" %} with {% extends "core/templates/base.html" %}.

Datastore vs spreadsheet for provisioning Google apps

If you use the Datastore API, you will also need to build out a way to manage users data in the system. If you use Spreadsheets, that will serve as your way to manage users data, so in that way managing the data would be taken care of for you. The benefits to use the Datastore API would be if you'd like to have a seamless integration of managing the user data into your application. Spreadsheet integration would remain separate from your main application.

In my company we want to build an application in Google app engine which will manage user provisioning to Google apps. But we do not really know what data source to use? We made two propositions : spreadsheet which will contains users' data and we will use spreadsheet API to get this data and use it for user provisioning Datastore which will contains also users' data and this time we will use Datastore API. Please note that my company has 3493 users and we do not know too many advantages and disadvantages of each solution. Any suggestions please?

Just in case, did you run the command renice -20 -p {pid} instead of renice --20 -p {pid}? In the first case it will be given the lowest priority.

I am using ubuntu. I have some management commands which when run, does lots of database manipulations, so it takes nearly 15min. My system monitor shows that my system has 4 cpu's and 6GB RAM. But, this process is not utilising all the cpu's . I think it is using only one of the cpus and that too very less ram. I think, if I am able to make it to use all the cpu's and most of the ram, then the process will be completed in very less time. I tried renice , by settings priority to -18 (means very high) but still the speed is less. Details: its a python script with loop count of nearly 10,000 and that too nearly ten such loops. In every loop, it saves to postgres database.

Making a web app which allows the user to view the server desktop

To allow the user to interact with the desktop in real-time, you need to run the application in the users web browser. Interaction with a webserver would just be too slow to do anything meaningful. I do not know about any way to execute Python in a web browser, so I would rule it out. Some of your options for client-sided code execution are: Javascript (the recent addition of Canvas and WebSocket made it suitable for this kind of problem) Java Applets (felt out of favor recently due to security problems) ActiveX (IE- and Windows only, very rarely used in a public context nowadays) Flash (a popular but dying technology)

I did a pretty fair bit of scouring, yet could not find anything useful which answers my questions. Either that or I am asking the wrong questions. I am trying to make a web application which gives a user a graphical view of the server desktop. I have understood that somewhere in here X engine has to be invoked and I have also understood that this is not something that php can accomplish primarily because its a language which processes before sending requests, please correct me if I am wrong in this regard. You may say that what I am trying to accomplish is something akin to what teamviewer does only on the web. My dilemma is whether I should be using python or java for this task, both would be pretty apt for the task, but which one would be better? Please give your suggestions

You can check the IP easily by doing a ping from the command line to the domain name, as in "ping appspot.com". With this you will obtain the response from the real IP. Unfortunately this IP will change over time and won't make your GCM service work. In order to make it work you only need to leave the allowed IPs field blank.

I think Jinja makes sense for building this, in particular because it contains a full-on lexer and parser. You can leverage those to derive your own versions of this that do what you need.

I'd like to do somehow the contrary to what a template is used for: I want to write templates and programmatically derive a representation of the different tags and placeholders present in the template, to ultimately generate a form. To put it another way, when you usually have the data and populate the template with it, I want to have the template and ask the user the right data to fill it. Example (with pseudo-syntax): Hello {{ name_of_entity only-in ['World', 'Universe', 'Stackoverflow'] }}! With that I could programatically derive that I should generate a form with a select tag named 'name_of_entity' and having 3 options ('World', 'Universe', 'Stackoverflow'). I looked into Jinja2, and it seems I can reach my goal using it and extending it (even if it's made to do things the other way). But I am still unsure how I should do in some cases, eg.: if I want to represent that {{ weekday }} has values only in ['Mo', 'Tu', ...] if I want to represent in the template that the {{ amount }} variable is accepting only integers... Is Jinja a good base to reach these goals? If yes, how would you recommend to do that?

Noob questions about upload & security

Since you have app in C:\myap you need to run appcfg.py update C:\myap. It's just a path to you app on your machine. In windows command line. For example, "C:\Program Files (x86)\Google\google_appengine\appcfg.py" update C:\myap No, appcfg uses SSL while uploading. It's safe. If you mean to call application uploading - it's not really safe. I don't know why you need this. You can add app developers in App Engine admin console, so they will be able to deploy application from their accounts.

I have the myapp.py and app.yaml in my windows C:\myap directory. The docs say to use: appcfg.py update myapp/ to upload the app. I've downloaded/installed Python and the Google python kit. Sorry, for these noobish questions, but: Is the myapp/ listed above refer to c:\myapp on my windows machine? Or is it the name of my app on the google side? How/where do I type the appcfg.py to upload my directory? Are there any security issues associated with using my gmail account and email address? I'd like anybody from Second Life to be able to call this from in-world. There will be about a dozen calls a week. Are they going to have to authenticate with my email/password to use it? Thanks for any help you can provide!

Why do Python MVC web frameworks use views.py to contain route functions?

python,model-view-controller,web-frameworks

A view, from the django's perspective is what content is presented on a page. And the template is the how it is presented. A django view is not exactly a controller equivalent. The controller in some of those other frameworks is how the call of a function happens. In django, that is a part of the framework itself. Technically, there is nothing preventing you from renaming your views into controllers.- The URL routing scheme takes either the function or the string to the function. As long as you can send the appropriate string to the function (or the function itself), you can call your view whatever you want. However, for the reason stated in the paragraph above and for the fact of meeting the expectations of the other people that work on django, you should not really have files called controller.py. It's just a matter of getting used to. Hang in there for a bit.

I've developed many applications using the MVC pattern in Zend and Symfony. Now that I'm in Pythonland, I find that many frameworks such as Flask, Django and Pyramid use a file called views.py to contain functions which implement the routes. But, these "views" are really controllers in other MVC frameworks I've used before. Why are they called views in Python web frameworks? And, can I change them to controller.py without tearing a hole in the Python universe?

Trigger Django module on Database update

A better way would be to have that application that modifies the records call yours. Or at least make a celery queue entry so that you don't really have to query the database too often to see if something changed. But if that is not an option, letting celery query the database to find if something changed is probably the next best option. (surely better than the other possible option of calling a web service from the database as a trigger, which you should really avoid.)

I want to develop an application that monitors the database for new records and allows me to execute a method in the context of my Django application when a new record is inserted. I am planning to use an approach where a Celery task checks the database for changes since the last check and triggers the above method. Is there a better way to achieve this? I'm using SQLite as the backend and tried apsw's setupdatehook API, but it doesn't seem to run my module in Django context. NOTE: The updates are made by a different application outside Django.
