#26445 new Bug

Can't set password on User during migration that depends on contrib.auth

I have an app with migrations that depend on the contrib.auth migrations. In one of my own migrations I want to create User objects and set their password. When trying to set a password for User object either through .set_password() or directly on creation through e.g. .create_superuser() I get this error:

AttributeError: 'User' object has no attribute 'set_password'

Attached is a test project. Create a virtual env with Django 1.9 and run ./ migrate in it to see the error.

It seems like the password related methods are not available on the User object, only in the default manager, which I gather is not available in migrations. Is this intentional?

It is expected behaviour that these methods are not available in your migrations. The reason is shortly explained in Historical models: arbitrary code can't be serialized, so there is no general way to make the historical methods available in your migrations.

To avoid this problem you can use the make_password function directly and set the hashed password on your user:

from django.contrib.auth.hashers import make_password

user.password = make_password('password')

Was it a mistake to add use_in_migrations = True to the UserManager if it's not actually usable?
