InvalidBasesError при запуске миграции в Django

Question

Я пытаюсь найти django-cms.

Я сделал новый проект (после этих шагов). Но когда я делаю django migrateЯ получаю следующую проблему:

>>>python manage.py migrate
Operations to perform:
  Synchronize unmigrated apps: treebeard, menus, sekizai, cms, djangocms_admin_style
  Apply all migrations: sessions, reversion, auth, admin, contenttypes, sites, djangocms_picture
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  Applying djangocms_picture.0001_initial...Traceback (most recent call last):

This can happen if you are inheriting models from an app with migrations (e.g. contrib.auth)
 in an app with no migrations; see https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies for more

Вот мой INSTALLED_APPS:

INSTALLED_APPS = (
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.auth',
    'django.contrib.sites',
    'djangocms_admin_style', # for the admin skin. must be before 'django.contrib.admin'                             
    'django.contrib.admin',
    'cms', # django CMS itself                                                                                       
    'treebeard', # utilities for implementing a tree (replaces mptt)                                                 
    'menus', # helper for model independent herarchical website navigation                                           
    'sekizai', # for JS and CSS management.                                                                          
    'reversion', # to versionize content                                                                             
    #'djangocms_file',                                                                                               
    #'djangocms_picture',
    #'djangocms_video',                                                                                              
    #'djangocms_link',                                                                                               
    #'djangocms_text_ckeditor', # django text plugin                                                                 
)

Эта ошибка возникает, когда я раскомментирую одну из последних строк. Зачем? Как я мог это исправить?

Answer 1

Я нашел решение здесь.

Вы должны изменить MIGRATION_MODULES в настройках вашего проекта, удалив _django из некоторых значений. Связанная страница упоминает cms а также menus, но я должен был удалить его из djangocms_link а также djangocms_text_ckeditor тоже.
