python - aldryn_bootstrap3 : Field defines a relation with model '...' , 未安装或抽象的错误

Question

当我在我的 virtualenv 中运行 migrate.py 时，我收到以下错误:

$ python manage.py migrate aldryn_bootstrap3
CommandError: System check identified some issues:

ERRORS:
aldryn_bootstrap3.Boostrap3ButtonPlugin.link_file: (fields.E300) Field defines a relation with model 'File', which is either not installed, or is abstract.

我已将 aldryn_bootstrap3 添加到我的 settings.py 中的 INSTALLED_APPS。

Answer 1

Aldryn Bootstrap3 依赖 django-filer .你应该install it first :

INSTALLED_APPS = [
    ...
    'filer',
    'mptt',
    'easy_thumbnails',
    ...
]

你得到的错误(Field 定义了与模型"file"的关系，它要么没有安装，要么是抽象的)告诉你一些模型依赖于 Django 找不到的其他模型.

具体来说，在这种情况下，Aldryn Bootstrap3 模型依赖于在 django-filer 中定义的模型 File、Image 和 Folder。
