Admin page on django is broken

Question

I\'ve set up a django project with an admin page. It worked perfectly for the first couple weeks of development, didn\'t use the admin page for a while, and when I came bac

Answer 1

You can do the following:

• Enter your mysql (or other database console)
• USE YourDATABASE;
• SELECT * from auth_user;
• watch is_staff and is_superuser item
• UPDATE auth_user SET is_staff = "1" where username = "root";

Then you can login again!

Answer 2

Are you using a custom user model and forgot add it in settings.py? That is what just happened to me.

# Substituting a custom User model

AUTH_USER_MODEL = "app_custom_auth.User"

Answer 3

This problem may be related to the Authentication Backends. Please check your settings files for the AUTHENTICATION_BACKENDS parameter.

Try the following value:

AUTHENTICATION_BACKENDS = (
    ('django.contrib.auth.backends.ModelBackend'),
)

Answer 4

I had the same issue, but AUTHENTICATION_BACKENDS flag on settings file was not the problem for me. Using Django Rest Framework somehow i had modified the password without calling set_password therefore bypassing hashing the password. That's why it was showing the invalid login.

I was able to detect the issue by running simple test in order to test the user creation by a similar test:

from django.test import TestCase

from django.contrib import auth
from .models import *

class AuthTestCase(TestCase):
    def setUp(self):
        self.u = UserProfile.objects.create_user('test@dom.com', 'iamtest', 'pass')
        self.u.is_staff = True
        self.u.is_superuser = True
        self.u.is_active = True
        self.u.save()

    def testLogin(self):
        self.client.login(username='test@dom.com', password='pass')

It is also worth mentioning that I was creating a custom user named UserProfile

Answer 5

Try this; in tests.py:

from django.contrib import auth

class AuthTestCase(TestCase):
    def setUp(self):
        self.u = User.objects.create_user('test@dom.com', 'test@dom.com', 'pass')
        self.u.is_staff = True
        self.u.is_superuser = True
        self.u.is_active = True
        self.u.save()

    def testLogin(self):
        self.client.login(username='test@dom.com', password='pass')

Then run the test with python manage.py test <your_app_name>.AuthTestCase. If this passes, the system is working, maybe look at the username and password to make sure they are acceptable.
