Django：我如何获得用户不在查看请求之外？ [英] Django: How can i get the logged user outside of view request?

问题描述

我有一个需要记录的用户信息的类方法（视图外）。如何在不将请求传递给该方法的情况下，如何检索登录的用户？不幸的是，我找不到一个很好的解决方案，它不合逻辑只是不存在这样做的方式，因为Django应该存储在登录用户的某个地方。否则（我相信）不可能使用 django.contrib.auth.decorators 中的 @login_required 装饰器。对吗？

I have a class method (outside of a view) who needs the logged user's information. How can i retrieve the logged in user without passing the request to the method? Unfortunately i can't find nowhere a nice solution and it's not logical just not exist such a way to do it, because Django should store somewhere the logged in user. Otherwise (i believe) it would be impossible to use @login_required decorator from django.contrib.auth.decorators. Right?

所以如果不可能为什么不这样做？为什么Django这样工作，如果我想要的唯一想法是登录用户，而不是请求中的所有信息？

So if it's not possible why it's not? Why Django works like this if the only think i want is the logged in user and not all the informations inside request?

提前感谢

推荐答案

关于装饰器，这是错误的。实际上装饰器用请求参数调用。

About decorators, it is wrong. Actually decorators called with request argument.

我相信更好的办法是将用户或请求对象传递给类的方法。但是还有其他访问请求的方法。

I believe better way is that passing user or request object to class's method. But there are other ways to access request.

这是我们使用的代码。您需要将这个中间件添加到MIDDLEWARES中。进口&调用get_request函数。

Here is the code that we use. You need to add this middleware to MIDDLEWARES. And import & calling get_request function.

from threading import current_thread

from .exceptions import RequestNotFound

_requests = {}


def get_request():
    t = current_thread()
    if t not in _requests:
         raise RequestNotFound('global request error')
    return _requests[t]


class RequestMiddleware(object):
    def process_request(self, request):
        _requests[current_thread()] = request
