Question

我正在尝试发现django-cms。

我做了一个新项目（these steps之后）。但是当我做mime时，我会遇到以下问题：

django migrate

这是我的INSTALLED_APPS：

>>>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):

django.db.migrations.state.InvalidBasesError: Cannot resolve bases for [<ModelState: 'cms.PageUser'>, <ModelState: 'cms.PageUserGroup'>]
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

当我取消注释最后一行时，会发生此错误。为什么？我怎么能解决这个问题？

Answer 1

我找到了解决方案here。

您必须在项目设置中更改MIGRATION_MODULES，从某些值中删除_django。链接的网页提及cms和menus，但我必须将其从djangocms_link和djangocms_text_ckeditor中移除。

在Django中运行迁移时出现InvalidBasesError
