推荐答案

INSTALLED_APPS适用于非模型应用程序.模型是应用程序中的类，通常位于/«app_name»/models.py 中.

The INSTALLED_APPS is for apps not for models. Models are classes that live within your app, usually in /«app_name»/models.py.

我认为您误解了Django项目的结构.尝试完成一个教程示例.

I think you have misunderstood how a Django project is structured. Try working through a tutorial example.

典型结构:

/«project»/«app_name»/models.py

和设置中:

INSTALLED_APPS = [ ... '«app_name»' ... ]

您的路径将包含基础项目目录，因此您可以在需要的位置导入应用.

Your path will contain the base project directory, so you can import your app where you need it.

并使用它们:

from «app_name».models import *

尽管始终最好不要导入 import * ，而是为要导入的类命名.

Although it is always best not to import *, instead, name the classes you wish to import.

要在评论中回答问题:

如果您不喜欢将所有模型存储在一个文件中的想法(即使这样做很正常)，则可以创建一个称为模型的模块.为此，请创建一个名为/«project»/«app_name»/models 的目录，并在其中放入 __ init __.py (将其声明为模块)，然后创建您的文件在那里.然后，您需要将文件内容导入 __ init __.py 中的模块.您应该阅读有关Python模块的知识，以了解这一点.

If you don't like the idea of storing all your models in one file (even though it is normal to do this), you can create a module called models. To do this, create a directory called /«project»/«app_name»/models, inside it put __init__.py (to declare it as a module) and then create your files inside there. You then need to import your file contents into the module in __init__.py. You should read about Python modules to understand this.

要回答第二个评论问题:

要在admin中查看模型，您应该创建一个管理文件带有模型管理对象.

To view models in admin, you should create an admin file with model admin objects.

最后:

请通读教程，以确保您对Django有透彻的了解.否则，您会浪费自己的时间！

Please read through the tutorials to ensure you have a thorough understanding of Django. Otherwise you're wasting your own time!
