Question

我尝试将多个应用程序分组到“app”文件夹中，以便更好地进行管理。但是当我第一次迁移时，我得到了以下错误。

./manage.py makemigrations

Traceback (most recent call last):

    app_label, model_name = model.split(".")
ValueError: too many values to unpack

我为分割的模型添加了一个print语句，输出为：

auth.User
auth.Group_permissions
auth.User_groups
auth.User_user_permissions
app.ticketmgr.BasePriority

似乎“app.ticketmgr.BasePriority”有一个额外的“点”。实际上，应用程序名称是“ticketmgr”，但放在“app”文件夹中以便更好地管理。我可以知道如何使迁移工作吗？是否有任何额外的设置来支持将几个应用程序放在“app”文件夹中？下面是我的app文件夹，里面有2个应用程序（comm，ticketmgr）。

|____app
| |______init__.py
| |____comm
| | |______init__.py
| | |____admin.py
| | |____apps.py
| | |____migrations
| | | |______init__.py
| | |____models.py
| | |____role_required.py
| | |____tests.py
| | |____views.py
| |____ticketmgr
| | |______init__.py
| | |____admin.py
| | |____apps.py
| | |____forms.py
| | |____migrations
| | | |____0001_initial.py
| | | |______init__.py
| | |____models.py
| | |____tests.py
| | |____views.py

Answer 1

不需要更多。只需将"app.ticketmgr", "app.comm"添加到INSTALLED_APPS。

Answer 2

BasePriority未出现在您的项目目录中。也许它是一个模特？

已安装的应用行应为：

app.ticketmgr

由于BasePriority不存在，django获得3个参数，而不是app_label，model_name所需的2个参数。＆＃34; BasePriority＆＃34;是第三个参数，除了。
