基于Django类的通用视图和身份验证 [英] Django Class-Based Generic Views and Authentication

问题描述

我对Django很新（从1.3开始）。在构建应用程序时，我从第一天开始使用新的基于类的通用视图，使用内置类的组合，并在需要添加到上下文之间进行子类化。

现在我的问题是，我需要回到我的意见，让他们只能访问登录的用户。所有我发现的文档显示了如何使用旧的功能通用视图，而不是基于类的。

这里是一个示例类：

  class ListDetailView（DetailView）：
 context_object_name =list
 
 def get_queryset（self）：
 list = get_object_or_404（List，id__iexact = self.kwargs ['pk']）
 return List.objects.all（）
 
 def get_context_data（self，** kwargs）： 
 context = super（ListDetailView，self）.get_context_data（** kwargs）
 context ['subscriber_list'] = Subscriber.objects.filter（lists = self.kwargs ['pk']）
返回上下文
  

如何向django新的基于类的视图添加身份验证？

解决方案

还有一个认证mixin的选项，您将从中导出您的视图类。因此，请使用这个来自lid3t.com的mixin ：

  class LoginRequiredMixin（object）：
 
 @method_decorator（login_required）
 def dispatch（self，* args，** kwargs）：
 return super（LoginRequiredMixin，self）.dispatch（* args，** kwargs）
  

然后你可以创建新的认证需要的意见如下：

  from django.views.generic import DetailView 
 
 class MyDetailView （LoginRequiredMixin，DetailView）：
 .... 
  

，无需其他添加。感觉非常像不重复自己。

I am pretty new to Django (starting with 1.3). In building an app, I went with the new class-based generic views from day one, using a combination of the built in classes and subclassing them where I needed to add to the context.

Now my problem is, I need to go back to my views, and have them accessible only to logged in users. ALL the documentation I have found shows how to do this with the old functional generic views, but not with class-based.

Here is an example class:

class ListDetailView(DetailView):
    context_object_name = "list"

    def get_queryset(self):
        list = get_object_or_404(List, id__iexact=self.kwargs['pk'])
        return List.objects.all()

    def get_context_data(self, **kwargs):
        context = super(ListDetailView, self).get_context_data(**kwargs)
        context['subscriber_list'] = Subscriber.objects.filter(lists=self.kwargs['pk'])
        return context

How do I add authentication to django's new class-based views?

解决方案

There's also the option of an authentication mixin, which you would derive your view class from. So using this mixin from brack3t.com:

class LoginRequiredMixin(object):

    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super(LoginRequiredMixin, self).dispatch(*args, **kwargs)

you could then create new "authentication required" views like this:

from django.views.generic import DetailView

class MyDetailView(LoginRequiredMixin, DetailView):
    ....

with no other additions needed. Feels very much like Not Repeating Oneself.
