如何在基于 django 类的视图上使用 permission_required decorator

我不太明白新的CBV是怎么工作的.我的问题是，我需要在所有视图中登录，并且在其中一些视图中需要特定的权限.在基于函数的视图中，我使用视图中的@PERMISSION_REQUIRED()和LOGIN_REQUIRED属性执行此操作，但我不知道如何在新视图上执行此操作.Django 的文件里有没有解释这一点的章节？我什么也没找到.我的代码中有什么错误？

我try 使用@method_decorator，但它返回"TypeError at /spaces/prueba/ _wrapped_view() takes at least 1 argument (0 given)"

以下是代码(GPL):

from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required, permission_required

class ViewSpaceIndex(DetailView):

    """
    Show the index page of a space. Get various extra contexts to get the
    information for that space.

    The get_object method searches in the user 'spaces' field if the current
    space is allowed, if not, he is redirected to a 'nor allowed' page. 
    """
    context_object_name = 'get_place'
    template_name = 'spaces/space_index.html'

    @method_decorator(login_required)
    def get_object(self):
        space_name = self.kwargs['space_name']

        for i in self.request.user.profile.spaces.all():
            if i.url == space_name:
                return get_object_or_404(Space, url = space_name)

        self.template_name = 'not_allowed.html'
        return get_object_or_404(Space, url = space_name)

    # Get extra context data
    def get_context_data(self, **kwargs):
        context = super(ViewSpaceIndex, self).get_context_data(**kwargs)
        place = get_object_or_404(Space, url=self.kwargs['space_name'])
        context['entities'] = Entity.objects.filter(space=place.id)
        context['documents'] = Document.objects.filter(space=place.id)
        context['proposals'] = Proposal.objects.filter(space=place.id).order_by('-pub_date')
        context['publication'] = Post.objects.filter(post_space=place.id).order_by('-post_pubdate')
        return context
