如何在django中编写自定义装饰器？ [英] How to write a custom decorator in django?

问题描述

问题 -

@is_premium_user
def sample_view:
          .......
          ......

我希望只有高级用户该网站。

如何在我的项目中的各种应用程序中使用这个装饰器？

I want certain views accesible to only the premium users of the website.
And how can I use this decorator across various applications in my project?

推荐答案

你不必为自己编写自己的装饰器作为 user_passes_test 已经包含在Django中。

You don't have to write your own decorator for this as user_passes_test is already included in Django.

还有一个代码片段一个延伸这个装饰器的href =http://djangosnippets.org/snippets/1703/ =nofollow noreferrer> group_required_decorator ）非常适合你的用例。

And there's a snippet (group_required_decorator) that extends this decorator and which should be pretty appropriate for your use case.

如果你真的想写自己的装饰器，那么有很多好的文档在网上。

If you really want to write your own decorator then there's a lot of good documentation on the net.

而且，（重新）使用装饰器只是将装饰器放在路径上的一个模块中，您可以从任何其他模块导入。

And well, to (re-) use the decorator just put your decorator in a module on your path and you can import it from any other module.
