I need help understanding what the advantage of using an asynch framework is. Suppose I want to develop a simple chat web app. Why cant I write python code in the Django framework that does long polling where I dont send a response back the server until someone enters a new msg. What does Twisted provide that gives it an advantage for re...
I'm using Django Contact Form on a website to allow visitors to send emails. Currently, it's escaping characters, so single and double quotation marks are converted to ' and " respectively. The emails would be more readable if quotation marks were displayed as ' and ". I understand why I should never put unescaped input from ...

When viewing the admin change list for a model, is it possible to make the columns that correspond to foreign keys links to their respective pages? A simple example is I have a Foo object which contains Bar as a foreign key. If I'm viewing the admin change list for Foo (and have it set to include Bar in the display_list columns), the m...
Hi all, I have problem about django template-db query relationship. For example, I created two tables in db (e.g. Menu & Submenu). Submenu, as you can guess, has a ForeignKey relationship with Menu. On the template side how can Ido db-query according to this relationship. I want to have a link for Menu such as: {% for menu in menu_li...
For reasons it's not worth getting into, the object Model of the django application I am working on is now "wrong" insofar as a number of relations that are 1 to Many are represented as Many to Many. The application functions correctly and is most of the way through QA. It has never been deployed. My design OCD makes me want to refact...
According to the documentation, if DEBUG is set to False and something is provided under the ADMINS setting, Django will send an email whenever the code raises a 500 status code. I have the email settings filled out properly (as I can use send_mail fine) but whenever I intentionally put up erroneous code I get my 500.html template but no...

Suppose JavaScript is disabled on the user's browser, TinyMCE won't load and the user could pass <script...
Just started with Django but hit a bit of a wall - I decided to experiment with writing a simple blog engine while referring to the django-basic-apps library. In blog/urls.py, I have this entry to map to the actual post by date, e.g. blog/2009/aug/01/test-post urlpatterns = patterns('', url(r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<d...
I am using Lighttpd + FastCGI + Django on a dev machine. I start FastCGI server via manage.py's command line option. Problem is that I do make changes to sources quite often and I need to get FastCGI to pick up those changes automatically, just as "./manage.py runserver" does. Is there a command-line option for that, perhaps, or any ot...

I'm using a Vote model which can be generically linked to several different models (to allow you to vote on different things). In some of my code I use annotations to count up the total number of votes and the positive number of votes for a queryset. I've noticed that if I place a vote on a certain item, then the other types of models ...
