Should I use get_user_model() when I have a custom user model?

Question

Django

Hello, such a question appeared after I rewrote the user model for the project.

The question is: It's
good to use get_user_model() when establishing relationships between models. The same situation, as far as I know, is the case with forms (in metaclasses).
But, what if I have a written model for the project, which will be the link everywhere? Is this feature worth using?

Answer 1

it's okay if you use it,
but in general, get_user_model() should be used if you are writing a library for Django - because it is not known if the user model will be overridden in the project where this library will
be installed, but if you use type hinting, function cannot be used, you have to do:

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from ... import User


def some_func(user: 'User') -> 'User':
    ...
