Fresh install of cmsplugin-filer gives migration error, nonexistent parent node (u'filer', u'0001_initial')

[irslambouf]

Hello, did fresh install or cmsplugin-filer with pip install cmsplugin-filer added:

INSTALLED_APPS = (
    ....
    'filer',
    ...
    'cmsplugin_filer_file',
    'cmsplugin_filer_folder',
    'cmsplugin_filer_link',
    'cmsplugin_filer_image',
    'cmsplugin_filer_teaser',
    'cmsplugin_filer_video',
    ...
)

and

MIGRATION_MODULES = {
    'filer' : 'filer.migrations', 
     ...
    'cmsplugin_filer_file': 'cmsplugin_filer_file.migrations_django',
    'cmsplugin_filer_folder': 'cmsplugin_filer_folder.migrations_django',
    'cmsplugin_filer_link': 'cmsplugin_filer_link.migrations_django',
    'cmsplugin_filer_image': 'cmsplugin_filer_image.migrations_django',
    'cmsplugin_filer_teaser': 'cmsplugin_filer_teaser.migrations_django',
    'cmsplugin_filer_video': 'cmsplugin_filer_video.migrations_django',
}

try to run ./manage.py migrate, or makemigrations filer or runserver

and getting error:

Removed 'filer' : 'filer.migrations', migrated and then added it back. This gave following traceback:

Did ./manage.py dbshell and dropped all filer related tables, re-run migrations, and now works.

@irslambouf latest filer version is 0.9.11 which has improved Django 1.7 support If this should happen again with 0.9.11 please feel free to reopen this issue
