Description (last modified by Tim Graham)

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
