Django項目與管理面板問題

Question

我將所有模型存儲在一個名爲models的文件夾中，它對我來說工作正常。但是，admin.py存在一些問題，我應該在哪裏存儲此文件？在模型文件夾或應用程序文件夾內？當我試圖插入模型到管理面板時，我得到了一個錯誤。

錯誤：

這是完全正常的對象分成模塊到包等你只需要記住的Django只查找默認情況下一個包的根目錄下有admin.py和models.py文件。這裏的解決方案是明確導入所需的文件，這是一個很好的地方，它是首先編譯的__init__文件。

例如， （Django的1.4設置，在Django的結構here更多信息）：

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

可以轉換爲：

/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 

然後在你__init__.py您的應用程序文件夾裏面添加：

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

而且由於安裝的應用程序如何定義事物，因此您不應該忘記將app_label屬性添加到模型Meta類中：

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


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