从基于类的通用视图中获取 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

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())

我唯一能想到的就是通过添加

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)

上课.但这看起来很丑陋.还有别的办法吗?

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

推荐答案

您可以从班级内的任何位置访问 self.request(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

使这项工作的关键部分是当基于类的视图被调用时，各种有用的东西都存储在 self 上；以及请求 (self.request) 这包括根据 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.
