Say you have an Events model that contains information about the event. But what about things like slugs, titles and meta description that would go into the html?

You can get a set of books associated with a publisher with p.book_set.all(), but what do you need to do to get a set of authors associated with a publisher (through the books ...
I have an admin view which contains four foreign keys each with a few thousand entries. It is slow to appear in the browser. If I change the django model to eliminate the select boxes by adding raw_id_fields things become nice and snappy. So the slowness is due to the population of the select drop downs and also this is a known issue s...

My questions are: what are some successful methods ...

I am also not sure if my webhost would be cool with it. What I'd ...

I'm building a website using Ubuntu, Apache, and Django. I'd like to block people from filling out and submitting a particular form on my site more than once. I know it's pretty much impossible to block a determined user from changing his IP address, deleting his cookies, and so on; all I'm looking for is something that will deter the ca...
Short version: Is there a simple, built-in way to identify the calling view in a Django template, without passing extra context variables? Long (original) version: One of my Django apps has several different views, each with its own named URL pattern, that all render the same template. There's a very small amount of template code that...

How do I get the choices field values and not the key from the form? I have a form where I let the user select some user's emails for a company. For example I have a form like this (this reason for model form is that it's inside a formset - but that is not important for now): class Contacts(forms.ModelForm): def __init__(self, *args...

To put it simply a string which is returned from the view might look like this: test = "\"Foo bar\"" return render_to_response('index.html', {'test': test}) And is displ...
