Best practice to handle global 500 errors in Django?

okay, now I understand how Http404 works. So you have to define this Http500 exception somewhere, and catch it in middleware.

I have a django app running with MySQL and Redis as backend I have a function called redis_helper() to do redis queries. But sometimes Redis crash and needs sometime to bootup, so I need to return a friendly HTTP 500 error message. The problem is, django only defines Http404(Exception) class in django/http/__init__.py, not Http500(), so I have to manually add try ... except in every view function where redis_helper() was involved. It feel a bit ugly and repeating work. Are there any convenient way to raise server 500 error not using return HttpResponseServerError() in view functions? If I have to write Http500 class myself which file is the best place to write it? Regards and thank you!

A few tipps without knowing your code: 'debug_toolbar.middleware.DebugToolbarMiddleware' should be your last or second to last middle ware entry (not 100% sure how it works out with the flatpagefallback middleware) 'debug-toolbar' as last in the list of INSTALLED_APPS Double check if the toolbar's assets are loaded Make sure all toolbar settings are set. (DEBUG_TOOLBAR_CONFIG, INTERNAL_IPS) etc. The error should be something in there. I know of other problems related getting the toolbar displayed on flatpages so if you only checked on flatpages I suggest you try it on another module.

Hey, I've been using Django 1.2.1 for some time now and came across Django Debug Toolbar just the other day. It looks really useful and I'm really eager to try some stuff out. I installed exactly how the readme said. Step by Step. I put the middleware at the end just in case things get caught up but I'm using quite standard middleware (common, sessions, auth and csrf). However, it won't show up on any of my pages. I've tried moving the middleware but to the same effect. It seems as if I've installed something wrong. But, when I load up the Admin Section of django, the toolbar springs up. I'm not sure what I'm doing wrong. Can the content of my pages effect the toolbar coming up? It's outputting in the mime text/html... Anyway, any help is greatly appreciated. Thanks in advance. Here's my Settings.py: pastebin.com/Hu8TgANt

python,django,virtualenv

Since the question was about easy_install, it's useful to know that (with setuptools v2.1) you can specify version numbers with easy_install like you can with pip. Thus: $ easy_install django==1.3 will install django 1.3. This was important for my problem (which Google directed me here to solve), when I needed to install an old version of pip with easy install. Obviously "just install pip and do it there" doesn't work for that problem.

I just broke my environment because of django 1.3. None of my sites are able to run. So, i decided to use virtualenv to set virtual environment with different python version as well as django. But, seems like if i download the package and install using "sudo python setup.py install" this does not get added to my virtual environment, but my original environment. I tried "easy_install django" in virtual environment virtualenv_name/bin folder, and it worked, but the problem is django1.3 was chosen automatically and got added. I want to install django 1.2.5, is there a way that i can install easily to my virtual env?

To do that, I need to get the 5 user with the higher score than that user and 5 user with lower score than that user, and also the position of that particular user in the database. I could use the cursor() method to get the encoded cursor. But, I cannot get the 5 Entity before the user's identity and even so, I cannot get the position of the user in the database. Maybe I can use the offset to do the query, but How to get the offset of an Entity?

Flask is a new and a very active project with good documentation and guidelines for new development and plugins. Its community is quite large and Armin (the lead) is an A grade programmer. Hence it is definitely the better contender. Web.py is an older and more mature project which is more a library than a framework. It's what we use for the Internet Archives Open Library website. The documentation is spotty but the code is rock solid and it's over the years accrued a lot of useful utilities into it. The final decision is yours but for a new project, I'd go with Flask.

MySQL&django hangs on huge session delete

python,mysql,django

I am not MySQL expert, but I guess MySQL locks the table for the deleting and this might be MySQL transaction/backend related. When deleting is in progress MySQL blocks the access to the table from other connections. MyISAM and InnoDB backend behavior might differ. I suggest you study MySQL manual related to this: the problem is not limited to Django domain, but generally how to delete MySQL rows without blocking access to the table. For the future reference I suggest you set-up a session cleaner task which will clear the sessions, let's say once in a day, from cron so that you don't end up with such huge table.

If your table is MyISAM, DELETE operations lock the table and it is not accessible by the concurrent queries. If there are many records to delete, the table is locked for too long. Split your DELETE statement into several shorter batches.

I assume you have not read the MongoEngine claim. MongoEngine is a Document-Object Mapper (think ORM, but for document databases) for working with MongoDB from Python. This basically say it all. In addition: your claim that Pymongo would deliver objects is wrong....well in Python everything is an object - even a dict is an object...so you are true but not in the sense of having a custom class defined on the application level. PyMongo is the low-level driver wrapping the MongoDB API into Python and delivering JSON in and out. MongoEngine or other layers like MongoKit map your MongoDB-based data to objects similar to native Python database drivers + SQLAlchemy as ORM.

South creates a table in your database to track migrations that have been applied. The table is south_migrationhistory. You probably want to either drop the table (and re-sync your db) or delete it's contents. I imagine at the moment south thinks that it's applied migration that it hasn't, which may be confusing things.

I'm in the classic position of the novice coder, where in hindsight I'd do many things differently if I were starting my project over. I used South relatively early in my project, ran into some problems due to my lack of knowledge, and abandoned it, removing it from installed apps, and syncing the DB. I then learned enough SQL to make the basic changes I needed, and have made many small changes since. I'd like to take another stab at South to see if I could reorganize my code to reflect better coding practices. I've searched the South site, with help from stackoverflow, and found a guide from the creator for removing all traces of South and starting again-- remove from installed apps, use the manage.py tool to reset the south table in the db, and recursively delete the migrations subdirectories. But even though I've not been using south for a long time now (it hasn't been in my installed apps), this left my DB in an nonfunctional state-- not really sure why since I didn't get any error messages. Can anyone explain to a database novice what lingering impact south would have had on my database?

I know for a fact that you can call all your Java libraries using JRuby. You can use the ruby programming language on your front and back end via Rails (Rails is a framework written in ruby). The difference between MRI (Matz Ruby) and JRuby is that JRuby runs on the JVM, whereas MRI has its own VM which is different from the JVM. By running on the JVM, you gain access to a whole lot of Java libraries.

It looks like wp_install() gets called inside of /wp-admin/install.php during step 1, and after form data has been validated. If you submit ?step=1& ... (all of the other required form fields) it should result in calling wp_install. So yes, you should be able to use urllib(2) for this.

As the author of django-rest-framework it'd be great to pick your brains about which bits of functionality could do with fleshing out. :) (obv i've got some thoughts of my own and areas I'm planning to work on, but be really good to get some user perspective) Your absolutely right about the API browser not being limited to any particular framework. To me that's the big deal with DRF and I'd love to see more API frameworks take a similar approach. One of the supposed benefits of RESTful APIs is that they should be self-describing, and it seems counter-intuitive to me that so many of the Web APIs we build today are not Web browseable. Oh, and totally agree with jsw re. testing Web APIs in django, I wouldn't use the framework's browsable API to replace automated tests.

I'm writing a set of REST services for a Django project. I've been using django-rest-framework for a while. Because of its limited functionality I had to switch to django-piston which I quite enjoy. However, django-rest-framework had one really nice feature - it was able to display an admin-like interface for testing the created services from the browser. It's just terrific for debugging purposes. It's very simple: one form is displayed for each HTTP method like "GET", "POST", etc. Along with that a drop-down list of available content types and a text field for putting in the data to be sent. As I view it, this isn't really a feature in any way directly connected with a particular REST framework. It isn't even necessarily about Django. It could all be achieved just using HTML + JS, or an external website. My question is: What do you use for manual testing / debugging web services? Could you point me to some HTML snippet or a Django app that would do the described thing?

I made several tests in Selenium IDE and saved it as a test suite in the HTML format which works fine for importing back into selenium IDE. Now however I would like to expand these tests using python and when I click export test suite and choose python I get this error Suite export not implemented for the chrome://selenium-ide/content/formats/python-rc formatter How can I enable this option in selenium IDE? Note I also have found an additional plugin for Firefox that allows batch conversion of tests but still does not allow export of the entire test suite as one file. I realize I could combine these files by hand but in the future I would like to have this option in my workflow. Thank you. p.s Running Firefox 3.6 on fedora 14

I had the exact same problem - only with later versions of the different softwares: Python 3.3.2 and Django 1.5.1 under Eclipse with PyDev 2.7.5. I solved the problem differently: I simply copied the complete Django 1.5.1 folder into the Python "Resources" folder /System/Library/Frameworks/Python.framework/Versions/3.3/Resources/Django-1.5.1 and applied the interpreter again. This worked right away, letting me create a Django project from within the eclipse. Hope this helps. Frank

I have python 2.6.1 installed with django 1.3 and PyDev 2.0. I am able to import django and print the version from commandline. However, when I try to create a Django project with pydev or even import django I get an error. When creating the django project, I get "Django not found." error. I have tried removing and adding the pythong interpreter to rescan the site-packages. I see that django is not available in the Libraries section. I have even tried adding the folder manually and applying the setting. Am I missing something? Thanks

Capture google app engine logging output

The default logger sends logging output to stderr. Use your shell's method of redirecting stderr to a file (in tcsh, (dev_appserver.py > /dev/tty) >& your_logfile.txt, your shell may vary.) You can also use the logging module in python to change the logger to send directly to a file if you detect it's running locally (os.environ['SERVER_SOFTWARE'].startswith('Dev'))

How can one view the Google App Engine logs outside the Admin console? I'm developing, so using dev_appserver.py/the Admin Console and would like to see the logs as the records are emitted. I'd like to monitor the logging output in a console with standard Unix tools e.g. less/grep/etc, but there doesn't seem to be an option to direct the logging from the dev_appserver.py command, and I can't open a new file in GAE (e.g. a FileHandler), so file handlers won't work, and I think using a socket/udp handler would be a bit of overkill (if it's even possible). I'm hopeful there are other options to view the log. Thanks for reading.

I am doing this to mainly display small user profile pictures with their friends' usernames on the users homepage. Its going to be a list of 9 of their friends.

Mechanize and Javascript

Basically if you want something that deals with javascript then you need a real javascript engine, these invariably involve automating a real browser (I'm including headless ones in this). Java’s HtmlUnit doesn't do a very good job as it doesn't use a javascript engine from an actual browser. Phantom JS sounds ideal (as newz2000 points out) however I find that when manipulating pages with javascript it can be very difficult to debug your script if you can't actually see the page you're dealing with. This leads to solutions such as Selenium Webdriver which has a full python API to automate various browsers, however you must run a java jar and it actually launches the browser, so not the pure python solution you're after (but I think this is as close as you can get).

I want to use Mechanize to simulate browsing to a web page with active JavaScript, including DOM Events and AJAX, and so far I've found no way to do that. I looked at some Python client browsers that support JavaScript like Spynner and Zope, and none of them really work for me. Spynner crashes PyQt all the time, and Zope doesn't support JavaScript as it seems. Is there a way to simulate browsing with Python only (no extra processes) like WATIR or libraries that manipulate Firefox or Internet Explorer while supporting Javascript fully as if actually browsing the page?

web2py: Restrict user to only rows created by the user

This shouldn't be handled by web2py. Your database is supposed to handle user permissions for this, so you will need to look in the documentation for the db backend you are using. Also, if everyone has a separate user account on your front end that all connect to a single database user, then you won't be able to control the permissions at all without a bunch of independent "security" code added on top of and around your database. For instance, a table in the database that looks at a field supplied by web2py when it connects to determine the "user" and then set the hand coded privileges accordingly. Databases have users for this very reason.

I would like have additional settings tied to each user in my application (beyond, is_staff, is_admin etc etc). Basically I'd like to have different settings to customize their user experience (ie: don't show tooltips, how many rows to display in results tables, other flags for turning things on or off). Are there best practices for adding these types of settings, or example model to do this without touching the django user object (in the past when i needed a quick user property, i just added it to my django source code, but obviously know that this is a horrible idea). So when someone sucessfully logs in, I would grab the settings for the user and add them to the session. I wasn't sure if there was a pretty way, or best practice for doing this.

I have a virtualenv at /opt/webapps/ff/ with its own Python installation. I have WSGIPythonHome set to /opt/webapps/ff in my Apache config file (and this is definitely getting used in some capacity, because if I set it to a slightly different existing directory and restart Apache I get a 504). But if I e.g. assert False in a view somewhere to bring up the Django debug page, I see that settings.PYTHON_BIN is /usr/bin rather than /opt/webapps/ff/bin. How do I get Apache/mod_wsgi to use my virtual environment's Python binary? I thought setting WSGIPythonHome was the way to do this, but it only seems to affect which site-packages dir is used, not which binary is used. Thanks.

Here's my suggestion: modify your program to include a button for doing the transformation. When you click it, it should take the contents of the clipboard, do whatever transformation you want, and put the result back on the clipboard. Once you do that, to use it you select the text from the widget, use the keyboard to copy it to the clipboard, press the button on the GUI, then click back in the widget and use the keyboard to paste. Alternately, your program can just poll the clipboard every couple of seconds, do the transformation and put the results back (make sure your automatic polling ignores any changes caused by itself). With that you can do a select-all, copy, wait a couple seconds, then paste. This is pretty trivial to do in both Tkinter and wxPython, and I would guess it is equally trivial with most other GUI toolkits.

I am not sure how to accurately describe my problem , and right now i have a total mess in my head , so please deal with it and correct me if i am wrong , and i will be for sure. MAIN GOAL: Is to built a real time line chart , which updates itself without web page reloading based on data , which comes from stdout . So it basically must be python script , which gets every second value , and based on this values continues to draw line in a line chart . 1) Well basic tags in my head right now are : Javascript / AJAX , cgi , python http web server , SVG (Vector graphics). So basically the biggest problem , which i dont understand is how to continuesly transfer stdout values to the webpage . Should i write my own python http web server , somehow pass values and with javascript or ajax + SVG draw the chart . Or writing a http web server is a stupid idea and i can somehow make it work without it ? Any other suggestions , or pointing me to some tutorials or arcticles are welcome . Because right now i am very confused , especially on the part of continuesly passing values to webpage. Thx in advance. Hope you will be able to point me somewhere =)

That is, not YOUR project's directory but where python actually runs from. Not sure if that's it but it worked for me!!

I have two systems running the same set of Django unittests. Some of the tests use the @unittest.expectedFailure decorator. On one system, these are running fine and reporting at the end of the test run OK (expected failures=10, unexpected successes=2). On the other system, the same tests error, but raise _ExpectedFailure and _UnexpectedSuccess without tracebacks. Has anyone seen this behavior before? Is it a configuration issue? Both systems are running Python 2.7, Django 1.3, and have unittest and unittest2 installed.

This is not an issue only on Django or python, it's a thing of cloud and software engineering.

I believe Django is very good and I will use it my self in a similar project, my issue is not Django but the IaaS, the infrastructure where I will run this on. If you are still worried if Python is the answer then you can research about, Ruby on Rails, and asp .Net, even perl, php, stuff like that. To me, Python is definitely the answer.

As others suggested it is not a bad idea to view the file in a browser. Store it in utf-8 (like open('x.html','w').write(x.encode('utf-8'))), as most browsers are well equipped to handle utf-8. In the browser, you may need to change View->Character Encoding to Utf-8. You will need Arabic fonts on your machine, so the browser can use these to display the characters. Having written this, any file viewer/editor that is capable of decoding utf-8 and has access to the fonts can do this for you (e.g. vim works fine on my machine).

I have crawled some webpages using Python. I ripped off the html tags and only stored some content of those pages as repr(s). Most of those pages are not in English. Now how can I view the crawled content in its original language? For example, the crawler wrote only one line of some Arabic text to a txt file: u'\u0639\u0644\u0649' But when I open the txt file in text editer or browser it looks exactly as above, so it's basically not human readable.. Is there some easy way to render and display the string in Arabic? Thanks,

Is there a way, so that in the Restaurant admin, I have Menu as a tabular inline, with a link to go edit that menu (in it's own admin page, not inline) so that there I can display the submenus inline with the menu admin. Each submenu has a link to edit that submenu item (in it's own admin page, not inline) so that there I can display the dishes inline. THanks.

The random querystring idea is a good way to make sure the swf is downloaded everytime, but that might not be what you really want to do. Especially if your swf is large in size and it only occasionally needs to update. What I would do is have a service that outputs the most recent version number of my swf. You'll have to come up with a version scheme that works for you (could be an svn build number for instance). When the swf build number changes, the new swf gets downloaded to the web browser. This would be accomplished by having your old swf make a service call early in the load process, if it finds a swf build number newer than its own, it would make a javascript call to the web browser causing the swf to be reloaded, appending a new value onto the source url (using the random querystring technique). The javascript call would be made using ExternalInterface.call (in Actionscript). With this approach you can have your swf be cached until a newer swf is available for download, which will save your users bandwidth and load/bandwidth of your server.

I have a application developed in flex deployed on server. In the application data is filled by user and saved in cookies so as to be available even when the user closes the application. However if new version of application is released the user can still access the older version saved in the cahe. How can it be assured that whenever a new version of application is released the application is loaded from the server and not from the cache and at the same time data saved in the older version (in cookies) can also be accessed in the new version. Any pointers of accomplishing it using html, flex or python will high helpful. Thanks

Well, it is a sort of validation constraint, so maybe add a validator to the title field that in reality does not bother about the title, but checks the user etc.? (I think a field validator is passed enough information to pull this off, if not, overriding the post_validate method or listening to the corresponding event should work.) If you try this, bear in mind that post_validate is already called while the user is editing (ie on moving focus out of a field).

I'd either do what Lutger suggested (and maybe write a log parser to strip out just the SQL), or I'd run my migration against a test database with logging enabled on the test DB. Of course, if you can run it against the test database, you're just a few steps away from validating the migration. If it passes, run it again against production.

Parsing lines from a live streaming website in Python

858

0

python,stream,live,urllib

You'll have to periodically re-download the website. Don't do it constantly because that will be too hard on the server. This is because HTTP, by nature, is not a streaming protocol. Once you connect to the server, it expects you to throw an HTTP request at it, then it will throw an HTTP response back at you containing the page. If your initial request is keep-alive (default as of HTTP/1.1,) you can throw the same request again and get the page up to date. What I'd recommend? Depending on your needs, get the page every n seconds, get the data you need. If the site provides an API, you can possibly capitalize on that. Also, if it's your own site, you might be able to implement comet-style Ajax over HTTP and get a true stream. Also note if it's someone else's page, it's possible the site uses Ajax via Javascript to make it up to date; this means there's other requests causing the update and you may need to dissect the website to figure out what requests you need to make to get the data.

I'm trying to read in info that is constantly changing from a website. For example, say I wanted to read in the artist name that is playing on an online radio site. I can grab the current artist's name but when the song changes, the HTML updates itself and I've already opened the file via: f = urllib.urlopen("SITE") So I can't see the updated artist name for the new song. Can I keep closing and opening the URL in a while(1) loop to get the updated HTML code or is there a better way to do this? Thanks!

Yes, this is correct approach. To get changes in web, you have to send new query each time. Live AJAX sites do exactly same internally. Some sites provide additional API, including long polling. Look for documentation on the site or ask their developers whether there is some.

No. size=120 is something you could pass as the 2nd argument to the get_serving_url method. =s120 would be something that you append to the URL returned by get_serving_url. The effect is the same: larger images are scaled down, but smaller images are not scaled up.

In my server process, it looks like this: Main backend processes: Processes Huge list of files and , record them inside MySQL. On every 500 files done, it writes "Progress Report" to a separate file /var/run/progress.log like this "200/5000 files done" It is multi-processed with 4 children, each made sure to run on a separate file. Web server process: Read the output of /var/run/progress.log every 10 seconds via Ajax and report to progress bar. When processing a very large list of files (e.g. over 3 GB archive), the processes lock up after about 2 hours of processing. I can't find what is going on. Does that mean that /var/run/progress.log caused an I/O deadlock?

I'm writing a syndication client, with the aim being to have a client for devices, and a web site that has the same functionality. I shall develop the website using Django - this is already decided; the client shall be written in python with both a CLI and a PyQt4 GUI. I have been writing the clinet first, and it's fairly database-heavy, as everything is cached to enable it to be read while offline. It struck me today that it would make sense to use Django models for my application, to reduce the repetition of effort between the client and the website. My question is how easy it is to seperate this, and how much of Django I will need in my client to use Django's models. AFAIK I should not need to run the server, but what else is needed? I had an idea of generating the same html for my client as the website, but showing it withing Qt widgets rather than serving pages for a browser. Has anyone tried this sort of thing before? I'm starting on this already, but it would be good to get a warning of potential dead-ends or things that will create a maintainance nightmare...

I wonder why you would handle registration like that. The usual way to handle registration is: Write the user info to the database, but with an 'inactive' label attached to the user. Send an email to the user. If the user confirms the registration, then switch the user to 'active'. If you don't want to write to the database, you can write to a cache (like memcache, redis), then when the user confirms the registration, you can get the user info from the cache and write it to the database.

Yes, absolutely. You just need to have each client create an App Engine account with an application to which you have administrator access. You can adjust the settings on the application to forbid downloads of your code by the other administrators if that's appropriate for your agreement with the client. This also allows the clients to be billed directly for their instances' usage, and makes it completely impossible for data to leak between different clients' instances. Using multiple applications for multiple clients who are licensing your application almost certainly does not violate part 4.4 of the TOS, although don't take this as legal advice.

sqlalchemy identity map question

python,sqlalchemy,identity-map

So this all depends on how you setup your sqlalchemy connection. Normally what you do is to manage each wsgi request to have it's own threadlocal session. This session will know about all of the goings-on of it, items added/changed/etc. However, each thread is not aware of the others. In this way the loading/preconfiguring of the models and mappings is shared during startup time, however each request can operate independent of the others.

The identity map and unit of work patterns are part of the reasons sqlalchemy is much more attractive than django.db. However, I am not sure how the identity map would work, or if it works when an application is configured as wsgi and the orm is accessed directly through api calls, instead of a shared service. I would imagine that apache would create a new thread with its own python instance for each request. Each instance would therefore have their own instance of the sqlalchemy classes and not be able to make use of the identity map. Is this correct?

Starting with Python 2.6 you can apply the decorators to classes as well. There is no builtin pattern for callable classes because there are too many ways to implement them, but essentially the trick would be to override __call__ on the class and to have a wrapper decorator that instanciates the class. I was planning on having a class-based-view extension but so far nobody came up with some good behavior for it :)

Offloading the work to some other external process is really the right thing to do, and once you've done it, it's not likely to be the last time you do it. Celery/RabbitMQ is a decent solution, and the nice thing is they're already there. Recent RabbitMQ releases have a decent web-based management app and a decent management API that'll make babysitting pretty easy, and celery works pretty well in Django apps. You can do this with subprocess or threading, but to be honest, I think that's a bad habit to get into. Unfortunately, they're the most straightforward ways to do what you want to do if you don't want to offload things. If you wanted to go completely 'ghetto async email' you could have your app just dump emails to files in a directory and have a cron job check the directory for files in that directory every minute, and send them off as emails, but really that's a lot more work than rabbit/celery. I say just go with rabbit/celery. It's not as much work as it seems, and it's worth it going forward.

I have a django site. Certain actions by the end user send email to the rest of users in a group. When the number of users gets to be > 20 it can add 1-3 seconds to the request cycle, which I don't like. I'd like to be able to send the email from a non-blocking function. I know RabbitMQ and Celery in conjunction can solve this, but with 200 users that seems like over-engineering and it adds two more applications I have to install, understand, and babysit. I've done some research, and it appears that both threading.Thread and subprocess would be ways to wrap a non-blocking call. Am I missing an obvious way to do this? Are there downsides to using either the threading.thread or subprocess approach? Thanks, Ted

Multi tier architecture implementation on Python

This architecture really makes no sense. You're using Django, a full-stack web framework, for the front end, but not using it for the database. And you're using Pyramid, another full-stack web framework, for the web service side, thus ensuring that you duplicate all the business logic. Much as I am an advocate of Django, I would say it has no place in your architecture. It looks like the only thing you're really using it for is URL routing and templates, both of which Pyramid does itself fine - you can even use Jinja2, which is based on Django's template language, as the template language in Pyramid if you like. Doing it this way means that you can share the business logic between the front-end and web service code, since you'll almost certainly find that a lot of it will be the same. I must say also that I don't understand the division into tiers, which you have described as separate from the front-end/web service division. To me, the web service is the second tier. It makes no sense to have a further division.

I need to create web application, which can be reached by user as regular web site and as XML-RPC web service. Also web site should have mobile version. I'm planning to use next technologies: Django (for web frontends (regular and mobile)). Pyramid (for web service). SQLAlchemy, Memcached (for persistence level) Later other projects can reach this data and providing logic, so I think it is better to make two tiers. I see it in next way: Tier 1. Main logic service level. This level will provide API for frontend applications (Django powered web site, for example). Tier 2. Different mostly end client applications (web site, API for remote client devices). For communication between this tiers I'm planning to use XML-RPC protocol. In this case it will be easy to scale it and add new front end application or connect another projects to this (I believe it). I have main question, -- what can I use to make it easy build first tier? Maybe there is some framework good for that? And what do you think about this whole architecture. Because I'm filling that I'm thinking in Java terms developing in Python. Maybe there is some another idioms in Python world for such situations. Thanks for you time and help. P. S.

You should checkout the Turbogears framework as it is composed of several popular components: ORM with sqlalchemy, pylons for logic and support for WSGI, permits support for several templating engines for the frontend... endless.

Your web server would provide the PDF back to the user. You need to pick a framework, install the components, write the unit tests, write the code, debug the code and transition the code to production. It's hard (given the question) to determine what part of this you actually need help with.

Delete duplicates from GoogleAppEngine Model?

Quick? Probably not. If you did want to delete dupes, my approach would be to write a remote_api script. Query the model for all entities, sort by title, and fetch batches of 100. Keep a local Python dictionary of titles. If you encounter a new title, add it to the dictionary. If you encounter a known title, add the entity to a delete batch, and flush the deletes before moving on to the next query batch. Probably an excessive amount of work when you can just wipe out your datastore and re-import instead.

I have two Google App Engine Models. I ran my cron's a few times and now there are duplicate entries in my datastore. If it was easy to just delete my entire datastore and upload my data again I would. BUT it took 4 hours to upload last time so I am wondering is there a quick way of deleting entries with duplicate names in the "title" field within the model?

how to combine django and wordpress based on ubuntu and nginx

If you can get away with running Django and Wordpress as separate apps, you can just use nginx to handle which requests go to which app. For example, if the CMS portion you'd like Wordpress for is only a blog, you could have nginx send example.com/blog/ to wordpress, and anything else to django.

I'm working with the BeautifulSoup python library. I used the urllib2 library to download the HTML code from a page, and then I have parsed it with BeautifulSoup. I want to save some of the HTML content into a MySql table, but I'm having some problems with the encoding. The MySql table is encoded with 'utf-8' charset. Some examples: When I download the HTML code and parse it with BeautifulSoup I have something like: "Ver las \xc3\xbaltimas noticias. Ent\xc3\xa9rate de las noticias de \xc3\xbaltima hora con la mejor cobertura con fotos y videos" The correct text would be: "Ver las últimas noticias. Entérate de las noticias de última hora con la mejor cobertura con fotos y videos" I have tried to encode and decode that text with multiple charsets, but when I insert it into MySql I have somethig like: "Ver las Ãºltimas noticias y todos los titulares de hoy en Yahoo! Noticias Argentina. EntÃ©rate de las noticias de Ãºltima hora con la mejor cobertura con fotos y videos" I'm having problems with the encoding, but I don't know how to solve them. Any suggestion?

How to set up Apache server via an FTP account

django,apache,apache2,mod-python

If you only have user level access to the machine (ie: you don't have root), then you won't be able to control what web server runs and you can only control its settings to a limited regard. You will have to consider contacting your provider or looking for a different hosting package if the server doesn't meet you needs. Typically, if it is a hosting server, the administrators will already have web server software like Apache running. You simply just have to upload what you would like to have displayed (typically to a directory called "public_html" or something like that), and it will display when someone visits your site. Hopefully they support things like Django, otherwise you might need to look at other options. Your hosting provider is most likely to have specific and the most relevant instructions for how to upload your website.

The result which is from third-party website will be analyzed in my app. Then show the result of analyze to user. But there are some problems between my app and third-party website, so I want to change the framework of my app. user key in keywords in forms. store the keywords which in forms as cookie. automatically download one javascript which in my app (website), and run the javascript in user's computer. the javascript will get result from third-party website, and then sent the result to my app. my app will analyze the result (from third-party website) and then show the result of analyze to user. I want to know how can I do this, or what keyword should I search in Google.

There is no direct one-to-one step or howto available for migrating PHP+Zend to Python+Django as both are different, different languages and different design models. So, migration is not easy. For other comparison questions you have asked, the answer is it depends upon the use case. But just in case you are comparing for the project which you are going to undertake, go ahead with the one you are more familiar with and if you planning to start, then the answer will depend upon the camp you are asking. PHP camp will say start with PHP and it's framework and Python camp will say start with Python and Django. So, this is subjective too.

I plan on doing this by utilising javascript location.replace() within a wrapping doRefresh() javascript function. The problem I have is that I do not know how to call the javascript function from within my main event loop within the Python code. Is there a way to directly call the method? or Is there a way to indirectly call the method say via a button's onClick and a mimic screen tap? Thanks.

From my observation, the get_by_id() failed because it couldn't query the datastore. Btw, the setting of datastore is Master/Slave Replication.

If Model.get_by_id(id) returns None, this indicates that you've supplied an invalid ID, not that the method itself is unreliable. It's not inconceivable that this method could fail in the event of a system outage, but if it did, your call would throw a datastore exception, not return an empty result.

If by forwarding you mean HTTP redirection, you can check the Referer header. If you mean DNS resolving (e.g. distinguishing between your application being invoked via your own domain and .appspot.com one), there is SERVER_NAME environment variable (os.environ["SERVER_NAME"]) that stores the domain (e.g. www.example.com) used to issue the request.

What does INSTALLED_APPS setting in Django actually do?

yes. INSTALLED_APPS helps django to sync the database, run tests, get the urls to work and more related issues. Maybe your installed apps still works because the main one calls the others with imports, a django app is nothing more that a simple python module that is imported when called in the settings file, that's why you get a invalid syntax error after you run the development server because an import won't work with invalid syntax.

Use the safe filter only if you html-escape the data first. Otherwise you should use escape. If you want your users to be able to input data with html tags you could try to sanitize the input to prevent users from using <iframe>, <script>, etc, but allow other tags to be white-listed, and then mark it as safe.

I have a form with a jwysiwyg editor. Looking at it, it can use basic-formatting html tags using the formatting buttons like SO's. Upon submitting the form, I notice its saved into the database as-is, whereas if I enter stuff like <iframe> ... </iframe> into the editor I notice that it is html-encoded inside the table. Now, when I need to output whatever the user has submitted, can I safely use {{ output|safe }} to display the formatted text? Is this reasonably secure enough or how should I rectify?

I've been trying (unsuccessfully, I might add) to scrape a website created with the Microsoft stack (ASP.NET, C#, IIS) using Python and urllib/urllib2. I'm also using cookielib to manage cookies. After spending a long time profiling the website in Chrome and examining the headers, I've been unable to come up with a working solution to log in. Currently, in an attempt to get it to work at the most basic level, I've hard-coded the encoded URL string with all of the appropriate form data (even View State, etc..). I'm also passing valid headers. The response that I'm currently receiving reads: 29|pageRedirect||/?aspxerrorpath=/default.aspx| I'm not sure how to interpret the above. Also, I've looked pretty extensively at the client-side code used in processing the login fields. Here's how it works: You enter your username/pass and hit a 'Login' button. Pressing the Enter key also simulates this button press. The input fields aren't in a form. Instead, there's a few onClick events on said Login button (most of which are just for aesthetics), but one in question handles validation. It does some rudimentary checks before sending it off to the server-side. Based on the web resources, it definitely appears to be using .NET AJAX. When logging into this website normally, you request the domian as a POST with form-data of your username and password, among other things. Then, there is some sort of URL rewrite or redirect that takes you to a content page of url.com/twitter. When attempting to access url.com/twitter directly, it redirects you to the main page. I should note that I've decided to leave the URL in question out. I'm not doing anything malicious, just automating a very monotonous check once every reasonable increment of time (I'm familiar with compassionate screen scraping). However, it would be trivial to associate my StackOverflow account with that account in the event that it didn't make the domain owners happy. My question is: I've been able to successfully log in and automate services in the past, none of which were .NET-based. Is there anything different that I should be doing, or maybe something I'm leaving out?

@Hugo was right in that it was a settings.py problem. But I didn't had that problem when running through the Django environment. But when I wanted to run unit tests one by one (By using Pydev's run as unittest) it failed to run. What I needed to do was to add the Django settings module information, so for now what I'm doing is adding the following lines to my unit tests: from django.core import management; import BookIt.settings as settings; management.setup_environ(settings) This loads my Django project settings and allow me to run as regular unittest. If anyone has better suggestion on how to configure this more cleanly in Pydev please let me know.
