How can I localize this problem?

Answer 1

What's happening...
I have no idea tbh. It is worth noting a few things though, that the url, should call a method in the User Auth ModelAdmin at django/contrib/auth/admin called user_change_password. It has the following signature:
def user_change_password(self, request, id, form_url=""):
which is why the error is being raised, because somehow extra_context is being passed to it.
There is also a way for you to change the logged on users password, which does accept a extra_context kwarg. My best guess is that one of the apps has overwritten the standard auth ModelAdmin and done it not quite right. Certainly everything works fine with a fresh django 3.0.7 project.
How can I localize this problem?
I would remove all of your additional apps. Hopefully this will fix the problem. If it doesn't then this becomes more interesting. But if it does, I would add them back in one by one until it breaks, and then you'll figure out which additional app is breaking things.
maybe you even can help me cope with it.
There's a few things I can think of that you could do if you just want to change the password. You can change user details via the shell:
python manage.py shell
Then the following will enable you to change a password:
from auth.models import User
user = User.objects.get(id=1) # Or whatever user you want
user.set_password('my_new_password')
user.save()
This should do the trick. Even easier still, there is a management command that does it (but for this you will need to know the current password). You can simply run:
manage.py changepassword *username*

I had this issue (though in Django 2.2). It started after I took the advice from another Stack Overflow post on adding extra_context to every admin page. This seems harmless, but breaks the "change password" form. In the end I deleted the 'extra_context' changes to urls.py and added the extra_context ONLY to the admin forms I needed using the ModelAdmin add_view and change_view methods.
# New Layer Form
def add_view(self, request, form_url='', extra_context={}):
extra_context['CATALOG_TECHNOLOGY'] = settings.CATALOG_TECHNOLOGY
return super(LayerAdmin, self).add_view(request, form_url, extra_context)
# Edit Layer Form
def change_view(self, request, object_id, extra_context={}):
extra_context['CATALOG_TECHNOLOGY'] = settings.CATALOG_TECHNOLOGY
return super(LayerAdmin, self).change_view(request, object_id, extra_context=extra_context)
