django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet with Django’s user database authentication from Apache

[Binoy U]

Hello,

I have created a django project with only one application. I haven't made any changes in the application. Only added the application to the settings and updated static and media urls.

Migration is done and super user was created.

I have configured apache(version:2.4.29) and mod_wsgi(4.5.17) according to Authenticating against Django’s user database from Apache.

But getting the following error in apache error log.

Traceback (most recent call last):
  File "/home/User1/Documents/test/check_apache/check_apache/wsgi.py", line 13, in <module>
    from django.contrib.auth.handlers.modwsgi import check_password
  File "/home/User1/Documents/test/lib/python3.6/site-packages/django/contrib/auth/handlers/modwsgi.py", line 5, in <module>
    UserModel = auth.get_user_model()
  File "/home/User1/Documents/test/lib/python3.6/site-packages/django/contrib/auth/__init__.py", line 165, in get_user_model
    return django_apps.get_model(settings.AUTH_USER_MODEL, require_ready=False)
  File "/home/User1/Documents/test/lib/python3.6/site-packages/django/apps/registry.py", line 197, in get_model
    self.check_apps_ready()
  File "/home/User1/Documents/test/lib/python3.6/site-packages/django/apps/registry.py", line 132, in check_apps_ready
    raise AppRegistryNotReady("Apps aren't loaded yet.")

Please find files below wsgi.py

import os
import mod_wsgi

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'check_apache.settings')
from django.contrib.auth.handlers.modwsgi import check_password
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Error is triggered from from django.contrib.auth.handlers.modwsgi import check_password.

apache config file 000-defaults.conf

Authentication is enabled on the media url. So I hope the apache configuration is working fine. I have create a github repository if you would like to check.

I got this issue from a bigger project with many application and other django modules. But I could still reproduce the same issue with this simple project. Can you please help me to resolve this issue, thanks in advance!

Hello there,

That looks like a Django bug to me as auth.get_user_model() should only be performed

from within the check_password() function as it will certainly crash at the module level.

You should file a bug report so it gets addressed[0].

Best,

Simon

Hello again :)

Someone pointed out to me that it might be a documentation issue that requires

that you import check_password only after calling get_wsgi_application().

For example, your wsgi.py module would look like

import os
import mod_wsgi

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'check_apache.settings')

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

from django.contrib.auth.handlers.modwsgi import check_password

In all cases a bug report should be filled to either adjust the documentation or the calls to

get_user_model() in django.contrib.auth.handlers.modwsgi.

Best,

Simon

Hello Simon,

Thank you for the reply. I have changed it as you mentioned and it's working now. I will raise an issue to update the documentation.
