Admin 404s on users

[mail....@gmail.com]

I just know there's a simple explanation for this, but my brain is
fried.

My admin area decided today it was going to start throwing a 404 error
for every user.

When I go to the admin, under "Auth" and click "users" all is well. I'm
presented with a list of users.

When I try to click one of the users - any of the users - it 404s. Even
if I click on my own user name.

Try setting DEBUG=True and reading the 404 error page.

It doesn't give me anything to go on:

Page not found (404)
Request Method: GET
Request URL: http://gretschpages.com/admin/auth/user/1/

You're seeing this error because you have DEBUG = True in your Django
settings file. Change that to False, and Django will display a standard
404 page.

I had a similar problem the other day. I had made a mistake on one of
my fields of another model, which was edited inline via the User Model.

Are you saying you broke your model?

Mine validate.

Or am I misunderstanding?

Try running "manage.py syncdb" to install any permissions that might
be missing. I think an ObjectDoesNotExist exception is being raised
somewhere, causing the 404. I seem to recall having a similar problem
once, where the PermissionDoesNotExist exception was causing a 404.

Yes, I broke the model that was being edited by the USER model. From
memory mine also validated OK, because the problem lay with some of the
data in the DB - not the actual structure of the model. That's why I
was able to see a complete USER list and only got the error when I
clicked on the individual record.

Syncdb didn't appear to do anything.

Adrian, I think you're right about ObjectDoesNotExist, and I think
something in my database is off... any Ideas how to track it down?

Grasping at straws here, but I've been running lots of comparison sql
statements looking for any disparities or oddities, things like:
Select user_id from auth_user_groups where user_id not in (select id
from auth_user)
and I notice that user 1 (admin, superuser, me) isn't in
auth_user_groups. That's normal, right?

This is just killing me... I can't figure out why the admin is flaking
on auth. I've noticed it freaks out on auth_users and auth_user_groups,
but nothing else, not even gp_users, which extends auth_users.

Also, I commented out all apps in settings.py except the "default"
django ones, and it still happened.

Anyone got any more ideas? I kind of need user admin!

Hey Tim,

"svn update" your code, assuming you're using the Django development
version. Then, making sure DEBUG=True, try loading the admin user page
again. You will get a more useful error message. Let's cross our
fingers that the error message will help you debug what's wrong.

Ah ha!

DoesNotExist at /admin/auth/user/1/
ContentType matching query does not exist.

Request Method: GET
Request URL: http://gretschpages.com/admin/auth/user/1/

Exception Type: DoesNotExist
Exception Value: ContentType matching query does not exist.
Exception Location:
/home2/baxter/lib/python2.4/django/db/models/query.py in get, line 213

I'm not exactly sure what it means, but it's DEFINITELY more helpful.
Perhaps I should look at my content-type table?

Still no go... what the hell is it looking for?

Run this code:

"""
from django.contrib.contenttypes.management import create_contenttypes
from django.db.models import get_apps
for app in get_apps():
create_contenttypes(app, created_models=None, verbosity=2)

I got it!

I had a mismatch between content_types and permissions. Not sure how it
happened, but it's fixed!

Thanks to everyone, espeically Adrian, for your help. I feel like I can
actually use the admin again!
