How to organize authorization in Django with multiple applications?

Question

Django

There is a project with two applications - for issuing pages (browser view) and for api (mobile application). Both must use the same user model. What is the (ideologically) correct way to do this? Start a separate application for users? But what to insert into it besides the actual model?
I know that you can simply add users to the model of one of the first two applications, and simply import it in the second, but it seems that this is somehow ugly - after all, the applications are equal, and the model will be in one of them.

Answer 1

#myuserapp/models.py
class MyUser(AbstractUser):
....


#app1/models.py
from myuserapp.models import MyUser

class MyThingInApp1(models.Model):
     user = models.ForeignKey(MyUser)
....


#app2/models.py

from myuserapp.models import MyUser

class MyThingInApp2(models.Model):
     user = models.ForeignKey(MyUser)
