Override Django User Manager to only return active users in requests

Requires a method for calling User.objects.filter/get to return user objects with is_active equal to True.

I tried to define a user manager and monkey patch it on a user model, for example:

 class CustomUserManager(UserManager): def get_query_set(self): return super(CustomUserManager, self).get_query_set(). filter(is_active=True) User.objects = CustomUserManager() User.objects_all = UserManager()

But when I try to make a call to User.objects.get (), I get:
AttributeError: 'NoneType' object has no attribute '_meta'

Before I go any further, I want to say that I know that fixing a monkey like this is very bad in terms of maintainability - it will mean that it will be revised later, but now we need a quick fix.

Here's the full stack trace if someone wants this as well:

Do I need to apply a filter to a user model? Why don't you try to subclass this model instead ?, and the manager code for this.

 class CustomUserManager(UserManager): def get_query_set(self): return super(CustomUserManager, self).get_query_set(). filter(is_active=True) class MyUser(User): objects = CustomUserManager() # get an active user which username is 'foo' MyUser.objects.get(username='foo')

or use a proxy model

Found the answer in this post . Since his question is specific, and mine is general, I do not consider them duplicate, but the answer to his question also answers my questions.
