proxy model inheritance generates a migration file in a third party app

[Iliana Toneva]

 
Hello,

I am using a third party app actstream 
 
(https://github.com/justquick/django-activity-stream) and 
am creating a proxy for one of the original actstream models :

# myapp/models.py
from actstream.models import Action

# Subclass Action model and apply my own manager 
class MyAction(Action):
objects = MyActionManager()

class Meta:
proxy = True
app_label = 'actstream'


The issue that I am having is that when I run './manage.py makemigrations', 
that creates a migration file 0002_myaction.py and adds it to the third party 
app migrations (instead of adding it to myapp/migrations):


*Migrations for 'actstream':*

  *0002_myaction.py*:

- Create proxy model MyAction


# actstream/migrations/0002_myaction.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import migrations, models


class Migration(migrations.Migration):

dependencies = [
('actstream', '0001_initial'),
]

operations = [
migrations.CreateModel(
name='MyAction',
fields=[
],
options={
'proxy': True,
},
bases=('actstream.action',),
),
]

Is there a way to prevent this behavior and force './manage.py 
makemigrations' to create a migration file in myapp/migrations/ instead? 

Many thanks,
Iliana
