錯誤與aldryn_bootstrap3：字段定義與模型的關係「...」，這是未安裝，或者是抽象的

Question

當我在我的virtualenv運行migrate.py，我收到以下錯誤：

$ 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. 
aldryn_bootstrap3.Boostrap3ImagePlugin.file: (fields.E300) Field defines a relation with model 'Image', which is either not installed, or is abstract. 
aldryn_bootstrap3.Bootstrap3CarouselSlideFolderPlugin.folder: (fields.E300) Field defines a relation with model 'Folder', which is either not installed, or is abstract. 
aldryn_bootstrap3.Bootstrap3CarouselSlidePlugin.image: (fields.E300) Field defines a relation with model 'Image', which is either not installed, or is abstract. 
aldryn_bootstrap3.Bootstrap3CarouselSlidePlugin.link_file: (fields.E300) Field defines a relation with model 'File', which is either not installed, or is abstract. 
aldryn_bootstrap3.Bootstrap3FilePlugin.file: (fields.E300) Field defines a relation with model 'File', which is either not installed, or is abstract. 

我已在我的settings.py中添加aldryn_bootstrap3到INSTALLED_APPS。

Answer 1

Aldryn Bootstrap3取決於django-filer。您應該install it first：

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

你所得到的錯誤（字段定義與模型「文件」的關係，這是未安裝，或者是抽象）告訴你一些模型依賴於其他模型Django找不到。

具體而言，在這種情況下，Aldryn Bootstrap3型號取決於在django-filer中定義的型號File，Image和Folder。

爲了解決這個問題，我不得不添加'filer'到INSTALLED_APPS：http://django-filer.readthedocs.org/en/latest/installation.html#configuration
