Question

我将所有模型存储在一个名为models的文件夹中，它对我来说很好。但是admin.py存在一些问题，我应该在哪里存储这个文件？在模特文件夹内或app文件夹中？当我试图将模型插入管理面板时，我收到了错误。

错误：

将对象分成模块到包等是完全没问题的。您只需要记住，Django默认只在包的根中查找admin.py和models.py文件。这里的解决方案是显式导入所需的文件，这是首先编译的__init__文件的好地方。

所以，例如（Django 1.4设置，关于Django结构的更多信息here）：

/project_root
    /project
        __init__.py
        settings.py
        urls.py
    /app
        __init__.py
        admin.py
        models.py
    manage.py

可以转换为：

/project_root
    /project
        __init__.py
        settings.py
        urls.py
    /app
        __init__.py  # <- import statements
        /admin
            admin_foo.py
            admin_bar.py
        /models
            model_foo.py
            model_bar.py
    manage.py

然后在您的应用文件夹中的__init__.py内添加：

from .models.model_foo import Foo
from .models.model_bar import Bar
from .admin.admin_foo import FooAdmin
from .admin.admin_bar import BarAdmin

由于安装的应用程序如何定义内容，您不应忘记将app_label属性添加到模型Meta类中：

class Foo(models.Model):
    # fields...
    class Meta:
        app_label = 'app'


class Bar(models.Model):
    # fields...
    class Meta:
        app_label = 'app'
