DJANGO，获取当前用户名，用户组名，用户组权限

样例，为下一步自定义用户权限作一下代码准备：

def get_context_data(self, **kwargs):
        if self.request.user.is_authenticated():
            current_user_set = self.request.user
            print current_user_set
            current_group_set = Group.objects.get(user=current_user_set)
            print current_group_set
            print current_user_set.get_group_permissions()
            context = super(DeployVersionListView, self).get_context_data(**kwargs)
