(Reformatted description, please use the preview button and WikiFormatting.)

The problem is you are using the latest-development-level docs with a released level of the code, which does not have some of the recent changes introduced in trunk. Specifically, csrf_token does not exist in 1.1.1 or earlier. You can fix the problem you see by just deleting it from your template.

The 1.1 level of the tutorial part 4 is here:

(The problem of there being no link to the 1.1.1 docs is covered by #12155.)

Hmm, this response is what I read about the traps, which is fine except I'm using django-trunk - updated this morning:

Then I followed the dev instructions and am still getting errors, although they are new ones:

Traceback (most recent call last):

  File "/usr/lib/pymodules/python2.6/django/core/servers/", line 279, in run
    self.result = application(self.environ, self.start_response)

  File "/usr/lib/pymodules/python2.6/django/core/servers/", line 651, in __call__
    return self.application(environ, start_response)

  File "/usr/lib/pymodules/python2.6/django/core/handlers/", line 230, in __call__

  File "/usr/lib/pymodules/python2.6/django/core/handlers/", line 46, in load_middleware
    raise exceptions.ImproperlyConfigured, 'Middleware module "%s" does not define a "%s" class' % (mw_module, mw_classname)

ImproperlyConfigured: Middleware module "django.contrib.csrf" does not define a "CsrfViewMiddleware" class

From the dev instructions I've taken the new MIDDLEWARE_CLASS 'django.middleware.csrf.CsrfViewMiddleware' but otherwise have followed tutorial instructions (ie, I'm using the RequestContext section of part 3 in teh csrf instructions...)

It sounds like you're not following the tutorial exactly. If you're following the tutorial, you shouldn't need to delve into the CSRF documention at all - you should only need to follow the steps that the tutorial gives you. Also, django.middleware.csrf.CsrfViewMiddleware clearly does exist in trunk, as does the csrf_token template tag.

I don't know exactly what is going wrong with your particular setup; until we know there is a specific problem with the tutorial, this isn't something that should be in Trac. Please follow this up on Django-users and explain exactly what you have done; if it turns out that there is a problem with the tutorial, we can open a new ticket.

fwiw, the tutorial _doesn't_ work. Feel free to test yourself. I have been advised by #django irc to move back to stable.

comment:5 Changed 7 years ago by datakid

I apologise for being a pedant - please ignore this last comment.

comment:6 Changed 7 years ago by lukeplant

In case you didn't find your problem yet, I notice that the directory that contains your SVN checkout (~/source/django-trunk) does not appear in your tracebacks (which contain /usr/lib/pymodules/python2.6/django/...). This indicates that your SVN checkout is not being used i.e. it's not at an appropriate place on your PYTHONPATH. I recommend virtualenv for sorting this kind of thing out.
