Question

Recently I splitted an app into two separate ones because I had 15+ models in it. I had got the “circular import error”. To solve this I tried writing this:

from django.db import models

class App1Model(models.Model):
    app2model = models.ForeignKey(app2.App2Model)

The error I’m getting is: “NameError: name ‘app2’ is not defined”. But app2 is correctly added into installed apps and into the path.

project
    -app1
        --models.py
    -app2
        --models-py

Answer 1

ForeignKey can take a string as an argument, i.e. models.ForeignKey('app2.App2Model'). Of course, you should try to design your code to avoid any circular dependencies in the first place.
