I have following code:
'''app_A/models.py:'''
{{{
class AbstractModel1(Model):
class Meta:
abstract = True
class AbstractModel2(Model):
model1 = ForeignKey('Model1')
class Meta:
abstract = True
}}}
'''app_A/models.py:'''
{{{
from .abstract import AbstractModel1, AbstractModel12
class Model1(AbstractModel1):
pass
class Model2(AbstractModel12):
pass
}}}
'''app_B/models.py:'''
{{{
from app_A.abstract import AbstractModel1, AbstractModel2
class Model1(AbstractModel1):
pass
class Model2(AbstractModel12):
pass
}}}
in Django 1.8, the `app_B.Model2.model1` would point to `app_B.Model1`,
but in Django 1.9.2 it points to `app_A.Model1` so my code no longer
works.
