I figured out a weird way to do this a while back but decided it was a
bad idea. It works, though:
models_a.py:
from django.db import models
class A(models.Model):
text = models.TextField()
number = models.IntegerField()
class Admin:
pass
models_b.py:
from django.db import models
class B(models.Model):
phone = models.PhoneNumberField()
class Admin:
pass
models.py:
from django.db import models
from models_a import A
from models_b import B
class ref_a_to_b(models.Model):
a = models.ForeignKey(A, edit_inline=True)
ref_to_b = models.ForeignKey(B, core=True)
class ref_b_to_a(models.Model):
b = models.ForeignKey(B, edit_inline=True)
ref_to_a = models.ForeignKey(A, core=True)
You could also not have these as edit_inline and have a separate form
in the admin for dealing with the relations.
