在Django中，如何为每个函数写一个？ [英] In Django, how do I write a this for every function?

问题描述

每当有人加载页面时，我想在控制台中打印Hello。

Whenever someone loads a page, I want to print "Hello" in console.

我不想为我所有的100个视图添加装饰器。太傻了
我想要这个装饰器自动添加到我的视图。
Hmm ...

I don't want to add a decorator to all my 100 views. That's silly. I sort of want this decorator to automatically be added to my views. Hmm...

推荐答案

中间件： http://docs.djangoproject.com/en/dev/topics/http/middleware/#writing-your-自己的中间件

定义一个中间件类，覆盖上面定义的一个函数，打印Hello，返回适当的对象（根据文档）并将中间件类添加到您的settings.py

Define a middleware class, override one of the functions defined above, print "Hello", return the appropriate object (according to docs), and add the middleware class to your settings.py

class PrintHelloMiddleware(object):
    def process_response(self, request, response):
        print "Hello"
        return None

# settings.py
MIDDLEWARE_CLASSES = ( # ... usual middleware
                       'path.to.my.middleware.PrintHelloMiddleware',
                      )
