It is stated at https://docs.djangoproject.com/en/1.4/topics/db/queries
/#how-are-the-backward-relationships-possible in the third paragraph that
"the first time any model is loaded" Django iterates `INSTALLED_APPS` and
populates backrefs. Either this is plain wrong, or the text needs
clarification.
1. I create a minimal two-app project where app2.Model2 has a reference to
app1.Model1 and both `app1` and `app2` are in `INSTALLED_APPS`
2. I create a Model1: `Model1.objects.create()`
3. I write and run a script:
{{{#!python
from app1.models import Model1
m = Model1.objects.get().model2s.all()
}}}
4. and get
{{{#!python
Traceback (most recent call last):
File "f.py", line 8, in <module>
Model1.objects.get().model2s.all()
AttributeError: 'Model1' object has no attribute 'model2s'
}}}
If I add `import app2.models`, it'll work.
