从基于类的通用视图获取request.session [英] Get request.session from a class-based generic view

问题描述

有没有办法从基于类的视图中获取 request.session ？

Is there a way to get request.session from inside a class-based view?

例如，我有django.views.generic的

For instance, I have

from django.views.generic.edit import FormView

class CreateProfileView(FormView):
    def form_valid(self, form):
        # --> would like to save form contents to session here

        return redirect(self.get_success_url())

我可以想到的唯一的事情是覆盖 as_view 添加

The only thing I can think of would be override as_view by adding

def as_view(self, request, *args, **kwargs):
    self.session = request.session
    super(CreateProfileView, self).as_view(request, *args, **kwargs)

到课堂。但这似乎是丑陋的。有另外一种方法吗？

to the class. But that seems ugly. Is there another way?

推荐答案

您可以访问 self.request 从课堂内的任何地方（因此 self.request.session ）

You have access to self.request from anywhere within the class (and therefore self.request.session)

https://docs.djangoproject.com/en/dev/topics/class-based-views / generic-display /＃dynamic-filtering

这个工作的关键部分是当基于类的视图是被称为，各种有用的东西都存储在自己身上;以及请求（self.request），它包括根据URLconf捕获的位置（self.args）和基于名称的（self.kwargs）参数。

The key part to making this work is that when class-based views are called, various useful things are stored on self; as well as the request (self.request) this includes the positional (self.args) and name-based (self.kwargs) arguments captured according to the URLconf.
