django: failing tests from django.contrib.auth

Question

When I run my django test I get following errors, that are outside of my test suite:

AssertionError: 302 != 200

Could anyone explain me, what am I doing wrong or what I should set to get those tests pass?

Answer 1

Looks like you haven't got the 'user' key available in your context, or even no context at all...

In your settings.py do you have the following?

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.media",
    "django.core.context_processors.request",

     etc ....
)

Indeed, do you have TEMPLATE_CONTEXT_PROCESSORS at all? IIRC django-admin.py startproject doesn't actually include these in the default settings.py

Hope that helps

Answer 2

If you have Python 2.6.5, you need this patch: http://code.djangoproject.com/changeset/11821 .

Otherwise, did you import django.contrib.admin? There are certain templates that need to exist for django.contrib.auth 's tests (your code shouldn't be affected if they are not there) to work, and django.contrib.admin happens to provide them.

Answer 3

I have managed to reproduce the test results you are seeing by doing the following:

MIDDLEWARE_CLASSES = (
    'django.middleware.cache.UpdateCacheMiddleware',
    .... <your middleware classes> ....
    'django.middleware.cache.FetchFromCacheMiddleware',
)

If you have these lines, try removing them and re-running the unit test. I do not however have a solution for this.
