Question

我有以下网址：

主urls.py：

url(r'^accounts/profiles/', include('accounts.urls', namespace = 'accounts')),

accounts/urls.py

url(r"^(?P<email>[\w.@+-]+)/$", views.UserDetailView.as_view(), name='detail'),

我已创建UserDetailView以查看用户的数据

User = get_user_model()

class UserDetailView(UserProfileDataMixin, generic.DetailView):

    template_name = 'accounts/user_detail.html'
    queryset = User.objects.all()

    def get_object(self):
        return get_object_or_404(
                    User,
                    email__iexact=self.kwargs.get("email")
                    )

    def get_context_data(self, *args, **kwargs):
        context = super(UserDetailView, self).get_context_data(*args, **kwargs)
        user = self.request.user
        following = UserProfile.objects.is_following(self.request.user, self.get_object())
        context['following'] = following
        context['recommended'] = UserProfile.objects.recommended(self.request.user)
        return context

当我执行请求的用户登录时访问/accounts/profiles/luisa@gmail.com/ URL时，请求为O.K

[08 / Sep / 2017 23:56:20]＆＃34; GET /accounts/profiles/luisa@gmail.com/ HTTP / 1.1＆＃34; 200 23577

但是，我希望匿名用户或未经身份验证的用户加入此视图，这些用户未在我的应用程序中注册。当匿名用户访问/accounts/profiles/luisa@gmail.com/网址时，我收到此消息：

TypeError: 'AnonymousUser' object is not iterable
[09/Sep/2017 00:00:50] "GET /accounts/profiles/luisa@gmail.com/ HTTP/1.1" 500 151513

我的自定义管理器方法is_following()是：

def is_following(self, user, followed_by_user):
    user_profile, created = UserProfile.objects.get_or_create(user=user)
    if created:
        return False
    if followed_by_user in user_profile.following.all():
        return True
    return False

和recommended（）方法：

def recommended(self, user, limit_to=10):
    print(user)
    profile = user.profile
    # my profile

    following = profile.following.all()
    # profile of the people that I follow

    following = profile.get_following()
    # TO avoid recommend myself

    # Exclude the users recommendations which I already follow 
    qs = self.get_queryset().exclude(user__in=following).exclude(id=profile.id).order_by("?")[:limit_to]
    return qs

如何允许匿名用户访问我的UserDetailView？

Answer 1

首先创建一个LoginRequired类。

from django.contrib.auth.decorators import login_required
from django.views.generic import View
from django.utils.decorators import method_decorator


class LoginRequired(View):
    """
    Redirects to login if user is anonymous
    """
    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super(LoginRequired, self).dispatch(*args, **kwargs)

然后：

class UserDetailView(LoginRequired,UserProfileDataMixin, generic.DetailView):

＆＃39; AnonymousUser＆＃39; object不可迭代 - 匿名和经过身份验证的用户访问视图
