Of course that's possible and in fact it's the only way to "go live". You don't want to develop in your live server, do you? And it's true for any platform, not just django. If I understood your question correctly, you need a system to push your development code to live. Use a version control system: git, svn, mercurial etc. Identify environment specific code like setting/config files etc. and have separate instances of them for each environment. Create a testing/staging/PP environment which has live data or live-like data and deploy your code there before pushing it to live. To avoid any downtime during deployment process, usually a symbolic link is created which points to the existing code folder. When a new release is to be pushed, a new folder is created with new code, after all other dependencies are done (like setting and database changes) and the sym link is pointed to the new folder.

As a fledgling Django developer, I was wondering if it was customary, or indeed possible, to create a site with Django then transfer the complete file structure to a different machine where it would "go live". Thanks, ~Caitlin

You could use GIT or Mercurial - or other version control system. To put the site structure on a central server. After that you could deploy the site for example with fabric to multiple servers. For deployment process you should consider using for example virtualenv to isolate the project from global python packages and requirements.

I am scraping a web page with Scrapy. I wrote my spider and it works just fine, it scrapes a list of Items on a page (let's call it this the Main page). In the Main page every Item I consider has a link that leads to the detail Item page (let's call it this way) where detailed information about every item is found. Now I want to scrape the details pages too, but the spider would be different, there are different information to be found in different places. Is it possible to tell scrapy to look for links in a particular place and then scrape those pages linked with another spider I am going to define? I hope my explanation was clear enough. Thanks

If you're not looking for single sign-on, then likely you want to either do the work in the view, and if you need the session to persist, store it in the (local django) session object; or outsource it to something like celery, and again, keep anything you need to keep track of in the session object.

I've been using PyCharm for the past year and am very satisfied with the features included, coming from Visual Studio myself. It has got what you are requesting and more. It is not free, but there is a trial version. In my opinion money well spent. It has also got some Django support, but I've never used it myself.

generally each of your django PROJECTS (django-admin startproject) has its own server, project is the directory containing all your apps and contains the manage.py. each app ususally doesn't because a project is composed of apps. For developing django includes a development server you can run using runserver python manage.py runserver 0.0.0.0:8080

Simplifying development process for Django

As a Django developer i can assure you that it grows on you and becomes easier to understand the development environment. You should remember that settings.py is probably going to be where your thoughts will be for quite a while in the start; the good part is that its only once, after you got it up and running you'll only touch settings.py to add new modules or change some configuration but its unlikely. I believe there are hosts that integrate with git so that should not be a problem since you will probably just git clone your project's url into the host (and not forget to enable/configure wsgi) To leave the settings.py out of the mess, you will tell git not to track the file with: git rm file; and then when you add your files for commit you do it with git add -u so it refers only to your tracked files. I'm not sure if i was clear enough. (probably not) But, i hope i could help you in some way.

I'm a freelance editor and tutor as well as a fiction writer and artist looking to transition to the latter on a full-time basis. Naturally, part of that transition involves constructing a website; a dynamic site to which new content in various forms can be added with ease. Now, I've always intended to learn how to program, and I simply haven't the money to hire someone else to do it. So, having had a good experience with my brief dabblings in Python, I decided I'd go with Django for building my site. I set up a Fedora Virtualbox for a development environment (as I didn't want to jump through hoops to make Windows work) and went to town on some Django tutorials. Everything went swimmingly until life intervened and I didn't touch the project for three weeks. I'm in a position to return to it now, but I've realized two things in the process. First, I'm having to do a fair bit of retracing of my steps just to find where certain files are, and second, I don't know how I'd go about deploying the site after I'm done building it. My intention is to get the cheapest Linode and host off that until some theoretical point in the future where I required more. I suspect that re: the file organization issue, that's just something I'll become more familiar with over time, though if there are any tricks I should be aware of to simplify the structure of my overall Django development space, I'm eager to know them. However, what about deployment? How viable is it to, with sufficient knowledge, automate the process of pushing the whole file structure of a site with Git? And how can I do that in such a way that it doesn't tamper with the settings of my development environment?

I have a minor issue using py.test for my unit tests. I use py.test to run my tests and output a junitxml report of the tests. This xml report is imported in jenkins and generates nice statistics. When I use a test class which derives from unittest.TestCase, I skip expected failures using: @unittest.skip("Bug 1234 : This does not work") This message also shows up in jenkins when selecting this test. When I don't use a unittest.TestCase class, e.g. to use py.test parametrize functionality, I skip expected failures using: @pytest.mark.xfail(reason="Bug 1234 : This does not work", run=False) But then this reason is not actually displayed in jenkins, instead it will say: Skip Message expected test failure How can I fix this?

You could do a very simple kivy app, that would start a service (inside which you would do your "server" side, with a small engine like flask or bottle, but i guess cherryPy should work too), and in the main.py of the "kivy" app, don't import kivy, just import webbrowser and start a browser window to localhost:your port. This will use the android browser. edit: oh, services are android only for now, apparently ios 7 supports them too, but kivy-ios hasn't been updated to make use of them.

My application has an html-based front-end and uses python logic on the back-end. This application needs to run offline, not connected to the internet, so by "back-end" here I don't mean a server running remotely, but rather python logic running side-by-side in the same app as the browser/html engine. For Windows or Mac desktop apps, I build a Chromium Embedded Framework application, and then launch a sub-process which runs a CherryPy python application built using py2exe (or py2app). The client and the server then communicate using normal http. I'd like to achieve the same thing on both iOS and Android. I've researched several alternatives, but nothing seems to do quite what I need. Kivy is close, but as far as I can tell it doesn't offer a browser/html front-end, but rather provides its own layout engine on top of OpenGL. It has an extension mechanism, but that seems to be more about extending the python side, not the front-end side. On the other hand, I could start with PhoneGap and then add a python library as an extension (possibly using Kivy's mobile library build of python). Or for that matter I could just write a regular C++ app that embeds a browser and uses a python library build. On the third hand, I've played with using various python-to-javascript converters to get the back-end logic into something that can work with PhoneGap directly, but that approach gets pretty difficult given all of the python logic I have -- some of it just doesn't convert so easily. Do you know of apps that are displaying html and running python logic in the same app?

Writing an "interactive" client with Twisted/Autobahn Websockets

python,websocket,twisted,autobahn

Why do you need a thread to launch protocolInstance.sendMessage() ? This can be done in a normal reactor loop. The core of a twisted is reactor and it gives a much easier look at things when you consider twisted itself reactive - meaning it does something as a reaction (response) to something else. Now I assume that the thread you are talking about, also gets created and made in calling sendMessage because of certain events or activity or status. I can hardly imagine a case where you would just need to send a message out of the blue without any reason to react. If however there is an event which should trigger sendMessage, there is no need to invoke that in thread: just use twisted mechanisms for catching that event and then calling sendMessage from that particular event's callback. Now on to your concrete example: can you specify what "whenever I need" means exactly in the context of this question? An input from another connection? An input from the user? Looping activity?

Maybe I'm missing something here in the asynchronous designs of Twisted, but I can't seem to find a way to call the sendMessage() method "externaly". By this I mean, sending messages without being solely at the callback methods of Twisted/AutobahnWebsockets (like at onOpen or when receiving data from server at onMessage()) Of course I could launch a thread and call my_protocol_instance.sendMessage("hello") but that would defeat every purpose of the asynchronous design right? In a concrete example, I need to have a top wrapper class which opens the connection and manages it, and whenever I need I call my_class.send_my_toplevel_message(msg). How can I implement this? Hope I've been clear on my explanation. Thanks

I would do it in django. Have two DateFields in your model, both that could be blank and null. On the first time someone views your page (with both dates unset), create a view for the template request that sets the one of the DateFields to today = datetime.date.today() and the other to today + datetime.timedelta(8) to be 8 days after the current date. Save your updated model and then display that model in the template.

Django is set up to have projects that are collections of reusable, self contained apps. Each has its own model.py because they're tied closely to the views and templates for that app but may not be needed for the rest of the project.

Ususally you will start writing one app. Once in a time, you will recognize that there are features which are not very tightly related (e.g. user management or different sub-parts). Additionally, your models.py will start to be lengthy and want to have a clearer structure. This is the point in time where you start splitting your project in independent sub-parts - the apps. Still, they will work with the same database. And even better: some friendly guys might have built apps whih you can include in your project - each bringing teir models and - of course - interacting with your database. If everything in yourproject is closely related, there is no need for different apps.

I have an App that worked well on both GAE and test server till a few days ago. It connects to a remote site, logs in and browse pages and input information automatically. The remote site is using dynamic URLs to follow the session, each page gives the link for next call. The program is very basic : urllib2.urlopen then regexp to extract the next url key then new call to urllib2.urlopen and so on. Now my app works still perfectly on test server but fails when deployed on GAE : I have a series of calls to urllib2.open and most of the time, the remote site says it has lost the session already on the second call but 1/10th I could go to the third call and once GAE has gone successfully to the fourth call. This seems to point out that it is not a security issue with the remote site (which has not changed) nor a question of redirect and cookies I have read in other posts. Users reported to me that it worked well till the 14th of Sept 13 and the failure was reported to me on the 20th. Was there a change in the handling of URLfetch in GAE recently? I've just spent 2 days on the problem with no tangible clue. It may be a question of IP address? The remote server could control the session with the IP adress and the dynamicURL together and I can imagine that GAE does not garantee that in a same call to GAE, all calls to URLlib are handled by the same machine? This could explain why sometimes it works for two or three successive URLs. I do not know enough GAE internal mechanism to confirm. Thank you in advance for your ideas.

I have a similar problem and I could solve it by doing the following. Note this is just for the HTML output. Create an index.rst field with just the following: ====================== Javadoc of the API XXX ====================== As I am using the extension "sphinx.ext.autosectionlabel", this becomes a "level 1" section. Modify the Make file so, once the HTML is generated, it replaces the index.html of the section "Javadoc of the API XXX" with the Javadoc of my API. After this change, on the toctree I have a link to "Javadoc of the API XXX" and when you click it, you see the Javadoc. I know is not the proper way of doing it, but it is the only that I have come up with after many Google searches.

How do you include html docs generated by other tools such as nose, coverage, and pylint reports into Sphinx documentation. Should they go into the _static directory? and if so, how do you link to them? I am trying to build a concise package of all of the code development tool documentation into a .pdf or html.

Im building this app (using Unity3d) for a city hall and I need to split the content from the actual app since content must be easily changeable without having to update the app itself. I want to host the content on a server and use http get/post messages to retrieve the data. I also need to have a web editor (kinda like a CMS) so that the client can change the content himself. In the editor I would just have a list of "rooms", where each "room" would be one of three types (i.e. text screen, slideshow or audio). Depending on what type the room is, different parameters should be visible and editable. What language you suggest I write the server in? (the server that the app would contact in order to obtain the up-to-date content) Python i'm guessing here? What would be the easiest way to build the browser editor? Javascript and django?

I suggest that instead of creating your own templating language (which is what this task amounts to), you use one of the many which already exist, and use that to perform the necessary operations. Try Jinja2, Django Templates, or Cheetah to see what you fancy. There are also many others.

Just to be clear this is not a scraping question. I'm trying to automate some editing of similar HTML files. This involves removing content between tags. When editing HTML files locally, is it easier to open() the file then dump the content line by line into a string so it's easier to apply a regular expression? Thanks

For users of our Django app that receive their emails through gmail they are finding that emails are getting grouped into conversations that shouldn't be. I'm not sure what gmail expects in an email to consider it unique enough to not group as a conversation but when I send plain text emails with DIFFERENT subjects using send_mail or even try a multipart/alternative with EmailMultiAlternatives with an html body gmail still assumes they are part of the same conversation. Obviously this creates confusion when our application sends emails with different subjects and bodies to the same user and they are all grouped and gmail only shows the subject of the first message in the conversation. I have 100% confirmed by looking at the raw original email messages to make sure the emails are different subjects and bodies. I just want to know if I can change anything in how django creates the email message so it can play nice with gmail conversations. I am using python 2.7.4, and can replicate the "issue" with Django 1.4 and 1.5.

Do I need celery when I am using gevent?

18,992,940

python,django,celery,gevent

In short you do need a celery. Even if you use gevent and have concurrency, the problem becomes request timeout. Lets say your task takes 10 minutes to run however the typical request timeout is about up to a minute. So what will happen if you trigger the task directly within a view is that the server will start processing it however after a minute a client (browser) will probably disconnect the connection since it will think the server is offline. As a result, your data can become corrupt since you cannot be guaranteed what will happen when connection will close. Celery solves this because it will trigger a background process which will process the task independent of the view. So the user will get the view response right away and at the same time the server will start processing the task. That is a correct pattern to handle any scenarios which require lots of processing.

I am working on a django web app that has functions (say for e.g. sync_files()) that take a long time to return. When I use gevent, my app does not block when sync_file() runs and other clients can connect and interact with the webapp just fine. My goal is to have the webapp responsive to other clients and not block. I do not expect a zillion users to connect to my webapp (perhaps max 20 connections), and I do not want to set this up to become the next twitter. My app is running on a vps, so I need something light weight. So in my case listed above, is it redundant to use celery when I am using gevent? Is there a specific advantage to using celery? I prefer not to use celery since it is yet another service that will be running on my machine. edit: found out that celery can run the worker pool on gevent. I think I am a litle more unsure about the relationship between gevent & celery.

I would comment with this, but I don't have enough reputation. So - I'm not sure why you can't log into your server, but are you sure that you don't have delimiters? Because if you're using \x01 as a delimiter in FIX, the tag-values pairs will usually just be displayed as "all mashed together," but the hex dump of it reveals otherwise (coming from personal experience). Also, you might be getting downvoted because you haven't provided much context. If you provided the relevant bit of code or what your FIX output looks like, that might help.

I am working on a Django project that was created by another developer on a different machine. I see that in the root of the application, there is a .virtualenv directory. Is it possible to simply setup this project locally on my Windows machine using the project settings and Python version (the app uses 2.7), so that I can run it like a local Django application so debugging is feasible? I have access to the development web server and have copied the full source of the app down to my Win7 machine but cannot seem to get things setup correctly to run the app locally so I can debug. I currently have Python 2.7, 2.7.5 and 3.3.2 installed on my local dev machine. I would call myself pretty new to Django and Virtualenv. If anyone has any guidance on how I can get my environment straitened out so I can run the app with debugging, I would be very thankful. Thank you in advance.

you cant the best you can do is encrypt it with a reversible encryption ... but then you need to store the key somewhere ... eventually you will have some plain text somewhere (or encoded at best) that will allow decryption ... you could store the hash and do a query against a db that maps hashes to pw's but you still have the password in plaintext somewhere ... you cannot login with just a hash anywhere ... (because the hash ends up getting hashed and then no longer matches the expected hash) an option may be to use rainbow tables to find something that results in an identical hash and use that instead ... but if they are adding salts or anything you are once again out of luck

A button click in my app calls a view which does a few database changes and then redirects to a new views which renders html. When the user typically clicks on the link, he accidentally clicks on in twice to thrice in a couple of seconds. I want to block the view call if the same call was made less than 10 seconds ago. Of course I can do it by checking in the database, but I was hoping to have a faster solution by using some decorator in django.

Python program on server - control via browser

Django is a good candidate for the website, however: It is not a good idea to run heavy functionality from a website. it should happen in a separate process. All functions should be asynchronous, I.E. You should never wait for something to complete. I would personally recommend writing a separate process with a message queue and the website would only ask that process for statuses and always display a result immediatly to the user You can use ajax so that the browser will always have the latest result. ZeroMQ or Celery are useful for implementing the functionality. You can implement functionality in C pretty easily. I recomment however that you write that functionality as pure c with a SWIG wrapper rather that writing it as an extension module for python. That way the functionality will be portable and not dependent on the python website.

I have to setup a program which reads in some parameters from a widget/gui, calculates some stuff based on database values and the input, and finally sends some ascii files via ftp to remote servers. In general, I would suggest a python program to do the tasks. Write a Qt widget as a gui (interactively changing views, putting numbers into tables, setting up check boxes, switching between various layers - never done something as complex in python, but some experience in IDL with event handling etc), set up data classes that have unctions, both to create the ascii files with the given convention, and to send the files via ftp to some remote server. However, since my company is a bunch of Windows users, each sitting at their personal desktop, installing python and all necessary libraries on each individual machine would be a pain in the ass. In addition, in a future version the program is supposed to become smart and do some optimization 24/7. Therefore, it makes sense to put it to a server. As I personally rather use Linux, the server is already set up using Ubuntu server. The idea is now to run my application on the server. But how can the users access and control the program? The easiest way for everybody to access something like a common control panel would be a browser I guess. I have to make sure only one person at a time is sending signals to the same units at a time, but that should be doable via flags in the database. After some google-ing, next to QtWebKit, django seems to the first choice for such a task. But... Can I run a full fledged python program underneath my web application? Is django the right tool to do so? As mentioned previously, in the (intermediate) future ( ~1 year), we might have to implement some computational expensive tasks. Is it then also possible to utilize C as it is within normal python? Another question I have is on the development. In order to become productive, we have to advance in small steps. Can I first create regular python classes, which later on can be imported to my web application? (Same question applies for widgets / QT?) Finally: Is there a better way to go? Any standards, any references?

the idea is that, say a developer has a set of tests to run against locahost:8000 and he has hardcoded that in his tests. When we setup a proxy in a browser, the browser handles the proxy so that users only care about typing localhost:8000 instead of localhost:proxy_port. Browser actually sends request and receives response from the proxy port. Can we simulate such so that the tests don't have to change to localhost:proxy_port (and the proxy server knows to route to port 8000). instead, the developer can continue to run as localhost:8000 in his tests, but when he's running his tests, the request automatically goes through the proxy server. PS: Also without changing the port of the server. Since the assumption is that the port 8000 is running as application server and changing it to another port can break other things! So saying "change proxy server port to 8000 and my webapp server to 80001" doesn't solve the whole problem.

Looking to quantify the performance overhead of NewRelic monitoring in python django app

19,128,804

0

python,django,newrelic

For the Python agent and monitoring of a Django web application, the overhead per request is driven by how many functions are executed within a specific request that are instrumented. This is because full profiling is not being done. Instead only specific functions of interest are instrumented. It is therefore only the overhead of having a wrapper being executed for that one function call, not nested calls, unless those nested functions were in turn ones which were being instrumented. Specific functions which are instrumented in Django are the middleware and view handler function, plus template rendering and the function within the template renderer which deals with each template block. Distinct from Django itself, you have instrumentation on the low level database client module functions for executing a query, plus memcache and web externals etc. What this means is that if for a specific web request execution only passed through 100 instrumented functions, then it is only the execution of those which incur an extra overhead. If instead your view handler performed a large number of distinct database queries, or you have a very complicated template being rendered, the number of instrumented functions could be a lot more and as such the overhead for that web request will be more. That said, if your view handler is doing more work, then it already would generally have a longer response time than a less complex one. In other words, the per request overhead is not fixed and depends on how much work is being done, or more specifically how many instrumented functions are invoked. It is not therefore possible to quantify things and give you a fixed per request figure for the overhead. That all said, there will be some overhead and the general target range being aimed at is around 5%. What generally happens though is that the insight which is gained from having the performance metrics means that for most customers there are usually some quite easy improvements that can be found almost immediately. Having made such changes, response times can quite quickly be brought down to be below what they were before you started monitoring, so you end up being ahead of where you were to start with when you had no monitoring. With further digging and tuning, improvements can be even much more dramatic. Pay attention to certain aspect of the performance metrics being provided and you can also better tune your WSGI server and perhaps better utilise it and reduce the number of hosts required and so reduce your hosting costs.

I am working on a large Django (v1.5.1) application that includes multiple application servers, MySQL servers etc. Before rolling out NewRelic onto all of the servers I want to have an idea of what kind of overhead I will incur per transaction. If possible I'd like to even distinguish between the application tracking and the server monitoring that would be ideal. Does anyone know of generally accepted numbers for this? Perhaps a site that is doing this sort of investigation or steps so that we can do the investigation on our own.

Truncate Django CMS Placeholder

As you've seen, you can't truncate a placeholder, as a placeholder's job is simply to render content plugins that are added to it. Your only viable option is to truncate the field in the render template of the plugin, or to add a separate field on your model that can store the truncated text. Such a field could be populated automatically using a post_save signal handler.

I'm creating my own Django CMS blog plugin. I'm using a placeholder to hold the full content of the blog entry and I'm trying to figure out how to automatically create an excerpt from this placeholder. If it were simply a text field I know I could use "|truncatechars:15" in the template, but I don't know how to do this for a placeholder. Is there something I can use in the template or in the 'views.py' in order to truncate the placeholder? Thanks in advance.

from my understanding you can't zip files directly on s3. you would have to download the files you'd want to zip, zip them up, then upload the zipped file. i've done something similar before and used s3cmd to keep a local synced copy of my s3bucket, and since you're on an ec2 instance network speed and latency will be pretty good.

My Django app handles multiple subdomains like "first.domain.com", "second.domain.com" etc. My SESSION_COOKIE_DOMAIN is ".domain.com" to handle multiple subdomains. So when I access my app from first.domain.com or second.domain.com, I can see the same session cookie from both subdomains. So my question is; is it possible to set SESSION_COOKIE_DOMAIN to "first.domain.com" when it's being accessed from "first.domain.com" and "second.domain.com" when it's being accessed from "second.domain.com" ?

I need to make a Web Crawling do requests and bring the responses complete and quickly, if possible. I come from the Java language. I used two "frameworks" and neither fully satisfied my intent. The Jsoup had the request/response fast but wore incomplete data when the page had a lot of information. The Apache HttpClient was exactly the opposite of this, reliable data but very slow. I've looked over some of Python modules and I'm testing Scrapy. In my searches, I was unable to conclude whether it is the fastest and brings the data consistently, or is there some other better, even more verbose or difficult. Second, Python is a good language for this purpose? Thank you in advance.

How to use a library that imports memcache in App Engine

python,google-app-engine

To further clarify jayhendren's answer - if you are planning to use GAE's memcache service, you must use from google.appengine.api import memcache you cannot use an open source memcache library. The only scenario where you could use the standard python memcache lib is if you were running your own memcache service somewhere (e.g. on Compute Engine) and you wanted to connect out to that over a socket. I'm guessing you're not doing that. Assuming you want to use GAE's built in memcache service: since there are differences between the API defined by GAE's memcache lib and the standard python memcache libs, you will have to make some minor changes to memorised so that it can successfully talk to the GAE memcache library. For the most part though the developer facing functionality is the same as the standard python lib. If you get it working, let us know!

Alexa (via AWS) charges to use their API to access Alexa rankings. The charge per query is micro so you can get hundreds of thousands of ranks relatively cheaply. I used to run a few search directories that indexed Alexa rankings over time, so I have experience with this. The point is, you're being evil by scraping vast amounts of data when you can pay for the legitimate service. Regarding PageRank... Google do not provide a way to access this data. The sites that offer to show your PageRank use a trick to get the PageRank via the Google Toolbar. So again, this is not legitimate, and I wouldn't count on it for long-term data mining, especially not in bulk quantities. Besides, PageRank counts for very little these days, since Google now relies on about 200 other factors to rank search results, as opposed to just measuring sites' link authority.

This would be a separate function that I would call in Python (ideally) and pass in the paramaters of the URL and how long I wanted to get the average over, measured in days and then I could just use that information to weight my results! I think it could be fun to work on, but I also feel that this may be easy to do with some trick of the APIs some guru might be able to show me and save me a few sleepless weeks! Can anyone help?

Debian: From the file manager, click on Connect To server, connect to ssh by giving login credentials which will open your remote project on your file manager itself. Or you can go to the server using ssh via terminal and edit your project via command line text editor. IDE: If you are working with IDE such as Aptana or PyCharm, you can load the project from the server itself by login credentials.

When accessing a setting defined by your app in your apps' defaults, I'd suggest if settings.name: - the default is defined by you already. On the other hand, when writing an external app - I'd suggest if hasattr(settings, 'name'): - you can't expect your apps users will define all the defaults.

Please chime in if there are other methods but the ones I see most often are these two and they both exist in the django source. if settings.DEBUG: and if hasattr(settings, 'POSTGIS_VERSION'): The later has the advantage of having a default but in cases where a default would be an error (something is missing) is it better to use the first version? What's the rule on defaults, when should you put it in the settings.py file and when should you include it directly in the source like above?

But how can I find out what the original base of the URL is? I don't care about interactions with the links, but do want them to appear correct. Assume a site 'example.com/blog/new/i.html' i scrape that has 2 resources < link src="/style/style.css" > < link src="newstyle.css" >. Now if i set base as 'example.com/blog/new/i.html' wont the first one break

I've installed Nginx + uWSGI + Django on a VDS with 3 CPU cores. uWSGI is configured for 6 processes and 5 threads per process. Now I want to tell uWSGI to use processes for load balancing until all processes are busy, and then to use threads if needed. It seems uWSGI prefer threads, and I have not found any config option to change this behaviour. First process takes over 100% CPU time, second one takes about 20%, and another processes are mostly not used. Our site receives 40 r/s. Actually even having 3 processes without threads is anough to handle all requests usually. But request processing hangs from time to time for various reasons like locked shared resources, etc. In such cases we have -1 process. Users don't like to wait and click the link again and again. As a result all processes hangs and all users have to wait. I'd add even more threads to make the server more robust. But the problem is probably python GIL. Threads wan't use all CPU cores. So multiple processes work much better for load balancing. But threads may help a lot in case of locked shared resources and i/o wait delays. A process may do much work while one of it's thread is locked. I don't want to decrease time limits until there is no another solution. It is possible to solve this problem with threads in theory, and I don't want to show error messages to user or to make him waiting on every request until there is no another choice.

Every process is effectively a thread, as threads are execution contexts of the same process. For such a reason there is nothing like "a process executes it instead of a thread". Even without threads your process has 1 execution context (a thread). What i would investigate is why you get (perceived) poor performances when using multiple threads per process. Are you sure you are using a stable (with solid threading support) uWSGI release ? (1.4.x or 1.9.x) Have you thought about dynamically spawning more processes when the server is overloaded ? Check the uWSGI cheaper modes, there are various algorithm available. Maybe one will fit your situation. The GIL is not a problem for you, as from what you describe the problem is the lack of threads for managing new requests (even if from your numbers it looks you may have a too much heavy lock contention on something else)

In general, this will not make your application slower, however it can potentially slow you down your instance start-up time, but it generally isn't a problem unless you have very large complicated apps. The instance start up time comes into play whenever GAE spins up a new instance for you. For example, if your app is unused for a long period and you start it up once in a long while, or for example, if your app is very busy and need a new instance to handle the load. python loads your modules as needed. So if you launch an instance, and the request goes to main.py, then main.py and all the modules associated with it will get loaded. If your app is large, this may take a few seconds. Let's just say for example it takes 6 seconds to load every module in your app. That's a 6 second wait for whoever is issuing that request. Subsequent requests to that loaded instance will be quick. It's possible to break down your handlers to separate modules. If handler for \a requires very little code, then having \a in a separate file will reduce the response time for \a. But when you load \b that has all the rest of the code, that would take a while to load. So it's possible to take that 6 second load and potentially break it up into a few requests that may take 2 seconds. This type of optimization really depends on the libraries you need to load with each request. You generally want to do this later on, when you run into the problems, rather than design your layout for this purpose up front, since it's pretty difficult to predict. App Engine warmup requests also help alleviate this problem.

Running web.py as a service on linux

python,centos,web.py

In general, there are two parts of this. The "remote and event-based" part: Service used remotely over network needs certain set of skills: to be able to accept (multiple) connections, read requests, process, reply, speak at least basic TCP/HTTP, handle dead connections, and if it's more than small private LAN, it needs to be robust (think DoS) and maybe also perform some kind of authentication. If your script is willing to take care of all of this, then it's ready to open its own port and listen. I'm not sure if web.py provides all of these facilities. Then there's the other part, "daemonization", when you want to run the server unattended: running at boot, running under the right user, not blocking your parent (ssh, init script or whatever), not having ttys open but maybe logging somewhere... Servers like nginx and Apache are built for this, and provide interfaces like mod_python or WSGI, so that much simpler applications can give up as much of the above as possible. So the answer would be: yes, you still need Nginx or the likes, unless: you can implement it yourself in Python, or you are using the script on localhost only and are willing to take some risks of instability. Then probably you can do on your own.

I've used web.py to create a web service that returns results in json. I run it on my local box as python scriptname.py 8888 However, I now want to run it on a linux box. How can I run it as a service on the linux box? update After the answers it seems like the question isn't right. I am aware of the deployment process, frameworks, and the webserver. Maybe the following back story will help: I had a small python script that takes as input a file and based on some logic splits that file up. I wanted to use this script with a web front end I already have in place (Grails). I wanted to call this from the grails application but did not want to do it by executing a command line. So I wrapped the python script as a webservice. which takes in two parameters and returns, in json, the number of split files. This webservice will ONLY be used by my grails front end and nothing else. So, I simply wish to run this little web.py service so that it can respond to my grails front end. Please correct me if I'm wrong, but would I still need ngix and the like after the above? This script sounds trivial but eventually i will be adding more logic to it so I wanted it as a webservice which can be consumed by a web front end.

is there A chance to destroy a session via scripts(like python) before the IE/Chome exit? Not using browser options

19,262,430

python,security,session,cookies,browser

No. The server has no idea when a browser closes. Because the connection between the browser and the server is stateless, when a user closes a tab or shuts down the whole application, the server is unaware of it. It doesn't even destroy the session when you "manually close the browser or clean cookies". The Session does not expire until it times out. Sessions can be destroyed programatically (I suspect, I don't use Python), for example, when a user clicks the "Log Out" button you should be destroying their session programatically, but if they just close the tab... you can't. Using session cookies and having relatively short session timeouts in what you should be doing. Session cookies will be orphaned by the browser when the user closes a tab or the app, so even if they open it right back up, they will need to reauthenticate. And having a short session timeout means that their sessions will not be sitting idle, taking up memory, and waiting to be hijacked on your server.

I found the solution, you have to manually add a folder in /django/conf/locale/ with the language extension you want. Actually you can just copy past the en (english) folder and name it after the missing language (in my case mt). In this folder you can also edit the file formats.py to localize the dates, numbers etc. Restart django and your language will be natively supported.

One way is with straight django and raw sql. But it will look ugly. If you spend the time going through the pain of getting GeoDjango up and running you'll find it well worth the effort, as performing queries such as "find all locations within 5 miles" become very easy to implement.

I am working on a project that involves a spatial model, just 2 coordinates points with latitude and longitude - no areas, boundaries, lines etc. Can I get away just by using plain django or should I use GeoDjango? Do I need GeoDjango to do spatial queries (find all locations within 5 miles etc.)? Also, should I consider using MongoDB for the data storage? The other models should be fairly standard: users, relationships, events... basically pretty structured things that would fit nicely in a standard DB?

I am currently trying to make a once static page into a dynamic page. The customers does not want to change the url to not have the .html at the end of the url. So, as an example the current static page is /foo/bar.html which is located in my public folder, no problem. I can easily make it /foo/bar, but once I have a period pylons no longer excepts the route. current code:map.connect('foo', '/foo/bar.html',controller=controller , action='foo')

There is a python module, pyPDF, that can also be used to slice-and-dice PDF's. This could be used if you had already exported you Assets using the native program (example printing an AutoCAD drawing as a PDF, from within AutoCAD itself). Acrobat is pretty good at magically guessing how this should be done when using those difficult Proprietary applications with specialized formats. The disadvantage (from an automation point-of-view): is that now we probably need to script AutoCAD to output the PDF in an organized way, so that we can pass it on to pyPDF. (Or we do these kinds of things by hand, but that is not very scalable).

I am trying to embed various PDF documents into my ReportLab canvas. It seems that maybe you can hack in support for SVG (but I really need PDF). If you want pure python, the proper way is to pay for the commercial ReportLab-PLUS addons, which includes PageCatcher, a mighty powerful artwork/PDF toolset. Im not ready for the PLUS upgrade just yet, but I have one other potential solution: Adobe Acrobat. I use Acrobat quite often, but I have never attempted to automate it (using python+COM I suppose). I dont want to just slam PDFs together, because it will ruin indexing and Table Of Contents generated by ReportLab. What I would need to do is set some type of placeholder in ReportLab that simply takes up space, yet, it would need to leave some type of identifier for Acrobat to look for and replace. I will plan to fill in entire pages in Acrobat. Any idea how I can create this placeholder from the ReportLab side? It almost seems like I would want to embed metadata in the PDF that gives Acrobat exact instructions for the insertion. I also suppose adding actual entities could work, and then Acrobat will need to remove them or cover them up. I am try to merge AutoCAD drawings, Vector illustrations, and assorted reStructuredText snippets (using rst2pdf).

I'm working with a somewhat large set (~30000 records) of data that my Django app needs to retrieve on a regular basis. This data doesn't really change often (maybe once a month or so), and the changes that are made are done in a batch, so the DB solution I'm trying to arrive at is pretty much read-only. The total size of this dataset is about 20mb, and my first thought is that I can load it into memory (possibly as a singleton on an object) and access it very fast that way, though I'm wondering if there are other, more efficient ways of decreasing the fetch time by avoiding disk I/O. Would memcached be the best solution here? Or would loading it into an in-memory SQLite DB be better? Or loading it on app startup simply as an in-memory variable?

Fast encrypt, slow decrypt method for NDB Datastore

python,google-app-engine,encryption

It sounds like conventional cryptographical methods should meet your needs, e.g. AES256. When it comes to crypto you should try to innovate as little as possible. Use well-established and well-trusted methods -- when "rolling your own" it's very easy to make mistakes, and you don't get the benefit of peer review from the academic cryptography community. Make sure to benchmark how long the encryption with the strong algorithm of your choice actually takes before doing work to address the issue of the encryption blocking the request. Would a few hundred milliseconds' delay really be a problem? If it turns out encryption is too slow, you still shouldn't compromise on the quality of your encryption algorithm. A better solution to this would be to perform the encryption in a background thread and continue with the request immediately. Allot an ID in your database to the resource that is to be inserted in encrypted form, but don't bother with an intermediate, intentionally "mild" form of encryption before the "real" encryption. This layer would only be providing a false sense of security. If a user attempts to access a resource that has not yet been encrypted, return an error indicating that the resource is still being processed (or that the encryption has failed, if applicable). Make sure that there's no possibility of the encryption process failing or being delayed in a way that results in unencrypted data being kept around for longer than it should. If encryption can't succeed in a timely manner (because of disks being full / power failure / cosmic rays), the insertion must simply be allowed to fail and the unencrypted data must not be kept.

I have unencrypted web request data (not under my jurisdiction) that I would like to quickly save into the Datastore so as not to slow down the request process. The sensitive data occasionally is required to be opened by system users via the web. When a user makes such a request, it will require them to complete a reCAPTCHA before the decryption process starts and an event is logged regarding their behavior. Decryption time could suitably be up to 1 minute long for a string of between 10 and 20 characters. Is there an encryption algorithm usable on GAE which is slower to decrypt than encrypt that would be suitable in this case? I'm contemplating another method to alleviate the encryption time: temporarily store the data mildly encrypted with MD5 & hash quick encryption method, while a scheduled job iterates over any records not flagged as properly encrypted and economically applies very strong encryption (it would be acceptable for the user to be alerted that encryption has not yet finished if they tried to access the data immediately after input) Assuming the above method is feasible, then I assume I can encrypt the pants out of the data for a few minutes, rendering it extremely costly to try to decrypt if data is compromised but system is not.

Is it wise to rely on HTTP_REFERER in a web app?

python,web.py,http-referer

thefourtheye is right that you can't rely on REFERER. But that doesn't mean you can't use it. As a security measure (e.g., to prevent deep linking), it's laughably useless. But for convenience features, there's nothing wrong with it. Assume, say, a third of your users won't supply it. Is your navigation good enough without it? Is the benefit in making things a little nicer for 2 in 3 users worth it? Sometimes the answer is yes. Keep in mind that some proxies or user agents will intentionally send you garbage. If the REFERER is the same as the current page, or is not part of your app at all, don't use it. Also, ask yourself whether what you really want here is a redirect to REFERER, or JS window.history.back(). The former is a poor substitute for the latter if that's what you're intending it for (although it can occasionally be useful as a fallback for people who can't run JS).

As per the official Django documentation Projects vs. apps What’s the difference between a project and an app? An app is a Web application that does something – e.g., a Weblog system, a database of public records or a small poll app. A project is a collection of configuration and apps for a particular website. A project can contain multiple apps. An app can be in multiple projects.

A project refers to the entire application and all its parts. An app refers to a submodule of the project. It's self-sufficient and not intertwined with the other apps in the project such that, in theory, you could pick it up and plop it down into another project without any modification. An app typically has its own models.py (which might actually be empty). You might think of it as a standalone python module. A simple project might only have one app. For your example, the project is the whole website. You might structure it so there is an app for articles, an app for ranking tables, and an app for fixtures and results. If they need to interact with each other, they do it through well-documented public classes and accessor methods. The main thing to keep in mind is this level of interdependence between the apps. In practice it's all one project, so there's no sense in going overboard, but keep in mind how co-dependent two apps are. If you find one app is solving two problems, split them into two apps. If you find two apps are so intertwined you could never reuse one without the other, combine them into a single app.

Extract header/footer from PDF (programmatically)

python,pdf,document

Page headers and footers are not (at least not necessarily) located in some content part separate from the rest of the page content. Thus, in general there is no way to reliably extract headers and footers from PDFs. It is possible, though, to try and use heuristics which look at the whole PDF contents and try to guess what parts are headers and/or footers. If the PDFs you want to analyze are fairly homogeneous, e.g. all produced by the same publisher and looking alike, this might be feasible. The more divers your source PDFs are, though, the more complex your heuristics likely will become and the less accurate the results will be.

I thought this would be simple thing to figure out but I have not been able find any examples. I just want to run a function whenever a user logs in to the Django Admin.

I would probably go with - Apache2(mod_wsgi) + Nginx(Proxy) . Where Nginx will be serving the static content and directing the dynamic content request to Apache2 server . This will improve the performance of your application .

We want to write our Webapps in Python for High-Traffic use (800 req/sec), but we don't know which Webserver and module are the best one. We actually think Apache2 + mod_wsgi is a good option, but maybe Apache2 + FastCGI or Nginx + mod_wsgi oder FastCGI could be better. Any Ideas?

There are two possible answers to your question. If you have no need for running multiple copies of Python running different modules, you can simply change all instances of the string "Python27" in your PATH to "Anaconda" (assuming you want to run the Anaconda Python) as suggested in the comments. Alternately, if you want to run different combinations of modules in two copies of the same version of Python, you can segregate/partition the modules you install into Anaconda/default Python versions. If you install using Windows installer, just make sure both versions of Python are in the registry (they should be by default) and the install wizard should allow you to choose where you want to install it. You can also individually install modules from their source code, adding them to "C:\Python27\Lib" or "C:\Anaconda\Lib" depending on the environment in which you want to use them.

When I try and import BeautifulSoup into IPython Notebook I get an error message: ImportError: No module named BeautifulSoup. The package is installed and works perfectly in IDLE. When I check system version, it returns 2.7.5 |Anaconda 1.7.0 (64-bit)| (default, Jul 1 2013, 12:37:52) [MSC v.1500 64 bit (AMD64)]. This would seem to be the same version of python I run in IDLE, though minus the Anaconda. How can I fix this problem?

This is for users in Google Apps for Business or Education. Using the Reports API in the Admin SDK I can see when the admin changed another user's password, but I cannot find an API that will tell me when a user has changed their password. I have changed mine twice in the past couple days and it does not come up in Reports API any where. Thanks for the help.

Error while executing django sphinx

In for sphinx-doc (i have never used django-sphinx) it would never work to run make html inside the build folder. You need to go one folder level up so that the folders build and source ar visible. Most likely you will see the Makefile file here as well. Try to change directories and run make html again.
