The makemigrations management command has a problem with migrations dir

[japrogramer@…]

When the migration folder does not have an init
​http://codepad.org/U2nGptor

File "/home/archie/git/django/django/db/migrations/writer.py", line 150, in path basedir = os.path.dirname(migrations_module.__file__)
AttributeError: 'module' object has no attribute '__file__'

the problem lies with makemigrations.py line 134-36 they are checking to see if an init file exists in the migrations dir but it checks using a line that depends on the existence of __init__.py. line 130 , writer.path, following to see where this code comes from led me to line 149 and 150 which need there to be an init file for __file__ to be an attribute there ..
tl;dr
makemigrations checks for an init file using os.path.isdir but with a call that depends on an __init__.py for it treats it as a module before it knows if it is a module

I created an app with an empty migrations folder and ran makemigrations, but did not get an error.

$ mkdir polls/migrations
$ python manage.py makemigrations polls
Migrations for 'polls':
  0001_initial.py:
    - Create model Poll
    - Create model Choice

Could you clarify the steps to reproduce?

I got this problem for some unknown reason. I resolved it by deleting the migrations folder and running makemigrations again

I got this problem too. Could it because I'm on Python 3.

Delete the migrations folder, solve the problem.

I got this because I'd created a new migrations folder, but forgot to make it a Python package (no __init__.py) while I was migrating an app from South.

Ran in to this problem today on 1.7b4 and python 3.3. Same result on python 3.4.1.

The "makemigrations" command fails if the migrations folder is empty. It succeeds as soon as I created init.py in the folder. See this gist:
