Write a 404 (page not found) view
|
||||
=================================
|
||||
|
||||
When you raise :exc:`~django.http.Http404` from within a view, Django
|
||||
will load a special view devoted to handling 404 errors. It finds it
|
||||
by looking for the variable ``handler404`` in your root URLconf (and
|
||||
only in your root URLconf; setting ``handler404`` anywhere else will
|
||||
have no effect), which is a string in Python dotted syntax -- the same
|
||||
format the normal URLconf callbacks use. A 404 view itself has nothing
|
||||
special: It's just a normal view.
|
||||
|
||||
You normally won't have to bother with writing 404 views. If you don't set
|
||||
``handler404``, the built-in view :func:`django.views.defaults.page_not_found`
|
||||
is used by default. Optionally, you can create a ``404.html`` template
|
||||
in the root of your template directory. The default 404 view will then use that
|
||||
template for all 404 errors when :setting:`DEBUG` is set to ``False`` (in your
|
||||
settings module). If you do create the template, add at least some dummy
|
||||
content like "Page not found".
|
||||
|
||||
.. warning::
|
||||
|
||||
If :setting:`DEBUG` is set to ``False``, all responses will be
|
||||
"Bad Request (400)" unless you specify the proper :setting:`ALLOWED_HOSTS`
|
||||
as well (something like ``['localhost', '127.0.0.1']`` for
|
||||
local development).
|
||||
|
||||
A couple more things to note about 404 views:
|
||||
|
||||
* If :setting:`DEBUG` is set to ``True`` (in your settings module) then your
|
||||
404 view will never be used (and thus the ``404.html`` template will never
|
||||
be rendered) because the traceback will be displayed instead.
|
||||
|
||||
* The 404 view is also called if Django doesn't find a match after checking
|
||||
every regular expression in the URLconf.
|
||||
|
||||
Write a 500 (server error) view
|
||||
===============================
|
||||
|
||||
Similarly, your root URLconf may define a ``handler500``, which points
|
||||
to a view to call in case of server errors. Server errors happen when
|
||||
you have runtime errors in view code.
|
||||
|
||||
Likewise, you should create a ``500.html`` template at the root of your
|
||||
template directory and add some content like "Something went wrong".
|
||||
|
||||
Use the template system

Fortunately, there's a little bug in the ``polls`` application for us to fix

right away: the ``Poll.was_published_recently()`` method returns ``True`` if
|
||||
the ``Poll`` was published within the last day (which is correct) but also if
|
||||
the ``Poll``'s ``pub_date`` field is in the future (which certainly isn't).

the ``Poll``’s ``pub_date`` field is in the future (which certainly isn't).
|

You can see this in the Admin; create a poll whose date lies in the future;

you'll see that the ``Poll`` change list claims it was published recently.
