Django：将views.py分割成多个文件 [英] Django: split views.py in several files

问题描述

我的views.py变得太大了，很难找到正确的视图。那么如何将它分割成几个文件，然后导入呢？是否涉及任何速度损失？我可以使用models.py吗？

解决方案

在Django中，一切都是一个Python模块（* .py）。您可以创建一个包含 __ init __。py 的视图文件夹，您仍然可以导入视图，因为这也实现了一个Python模块。但是一个例子会更好。

您原来的 views.py 可能如下所示：

  def view1（arg）：
 pass 
 
 def view2（arg）：
 pass 
  

使用以下文件夹/文件结构，它将工作相同：

  views / 
 __init__.py 
 viewsa.py 
 viewb.py 
  / pre> 
 
 
  viewsa.py ：
  def view1（arg）：
 pass 
  
  viewsb.py ：
  def view2（arg）：
 pass 
  
  __ init __。py ：
 从viewa导入视图1 
 from viewsb import view2 
  
 快速的解释将是：当您从视图中输入 import view1  Python将寻找view1 
 
 
 
  views.py ，这是什么第一（原件）案例中的笔
 
 
 
 
  views / __ init __。py 第二种情况。这里， __ init __。py 能够提供view1方法，因为它导入它。
 
 
 
使用这种解决方案，您可能无需更改 import 或 urlpattern  s参数 urls.py  
 
 
 
如果每个新视图文件中有很多方法，您可能会发现对使视图/ __ init __。py 中的导入使用 * ，如下所示：
  from viewsa import * 
 from viewsb import * 
  
我实际上不知道速度问题（但我怀疑有什么）。
 
 
 
对于模型可能有点困难。 
 
My views.py has become too big and it's hard to find the right view. So how do i split it in several files and then import it? Does it involve any speed loss? Can i do the same with models.py?
解决方案
In Django everything is a Python module (*.py). You can create a view folder with an __init__.py inside and you still will be able to import your views, because this also implements a Python module. But an example would be better.

Your original views.py might look like this :
def view1(arg):
    pass

def view2(arg):
   pass
With the following folder/file structure it will work the same :
views/
   __init__.py
   viewsa.py
   viewsb.py
viewsa.py :
def view1(arg):
    pass
viewsb.py :
def view2(arg):
    pass
__init__.py :
from viewsa import view1
from viewsb import view2
The quick explanation would be: when you write from views import view1 Python will look for view1 in 

views.py, which is what happens in the first (original) case 
views/__init__.py, which is what happens in the second case. Here, __init__.py is able to provide the view1 method because it imports it.
With this kind of solution, you might have no need to change import or urlpatterns arguments in urls.py

If you have many methods in each new view file, you might find it useful to make the imports in views/__init__.py use *, like this:
from viewsa import *
from viewsb import *
I actually don't know about speed issues (but I doubt there are any).

For Models it might be a bit difficult.
