Hi,

I'm doing the tutorial and tried to set up my own 404 handler, following
the hints in the tutorial.
However, here the tutorial is not clear:

- where exactly does Django look for the handler404 name?
- should I assign a new object to django.conf.urls.defaults.handler404, or
create the name handler404 inside the views module?
- I did not create a 404.html, how come Django does not complain about
that? (quote: The default 404 view will use that template for all 404
errors.)

An example of setting up your own 404 handler would help a lot (I still
have not managed, so now it feels like I missed a point somewhere).
By the way, the tutorial is excellent in all other aspects!

Replying to [ticket:10934 mnieber]:

> - where exactly does Django look for the handler404 name?

According to the third paragraph of
[[http://docs.djangoproject.com/en/dev/topics/http/views/#the-404-page-
not-found-view the 404 doc]], Django looks in your `urls.py`.

> - should I assign a new object to django.conf.urls.defaults.handler404,
or create the name handler404 inside the views module?

This is also addressed in that same paragraph. You just define a variable
`handler404` and you're set.

> - I did not create a 404.html, how come Django does not complain about
that? (quote: The default 404 view will use that template for all 404
errors.)

AFAIK, django doesn't provide a default `404.html`. If you didn't create
one, you should get a 'template not found' error - that is, if you trigger
a 404, AND disable `DEBUG` or `TEMPLATE_DEBUG` in your settings (not sure
which).

If this isn't the case, then this is a bug with django's template loading
system which should be addressed in a separate ticket.
