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

Hello Iliana,

this is due to the definition of app_label = 'actstream' on your proxy model. This tells Django that this model should belong to another app. Hence the migrations involving that model are added to the actstream app's migrations.
