Django: How to create a model from a definition in another module

Question

Lets say I have this Django setup:

appA - models.py
     - views.py
     - etc...

global - models.py

What I want is import the models from global.models in appA.models so that they are treated as a normal appA models by syncdb and south.

global.models:

from django.db import models
class Foo(models.Model):
    #django model stuff

appA.models: try 1:

from global.models import *

>>manage.py schemamigration appA --auto
>>does not see Foo

try 2:

from global.models import Foo

class Foo(Foo):
    pass

>>manage.py schemamigration appA --auto
>>Error: One or more models did not validate:
>>appA.Foo: 'foo_ptr' has a relation with model <class 'global.models.Foo'>, which has either not been installed or is abstract.

What is the correct way to accomplish this?

from .models import Foo

class Foo(models.Model):
    #stuff

    class Meta:
        abstract = True

>>manage.py schemamigration appA --auto- >>Deleted model appA.Foo >>Created 0005_auto__del_foo.py. You can now apply this migration with: ./manage.py migrate runengine – RickyA Mar 18 '13 at 12:48
why not make your Foo as an abstract? – catherine Mar 18 '13 at 12:50

global is a python statement, you should not use it to name one of your package. Try using a different name, and don't forget to put a __init__.py file in the directory to turn it into a python package.
