使用带有 def 的 mixin

Question

我在 generic.views 上使用这个 Accessmixin：

class OrganisorAndLoginRequiredMixin(AccessMixin):
    """Verify that the current user is authenticated and is an organisor."""
    def dispatch(self, request, *args, **kwargs):
        if not request.user.is_authenticated or not request.user.is_organisor:
            return redirect("home")
        return super().dispatch(request, *args, **kwargs)

我想在 def 上使用它。我试过这个，但我有以下错误。

@OrganisorAndLoginRequiredMixin()
def AgentUpdateView(request, pk):
    obj = Agent.objects.filter(pk=pk).first()
    if obj is None:
        return render(request, "404.html", {
            "Instance": pk
        })
    else:
        form = AgentModelForm(instance=obj.user)

错误： TypeError: 'OrganisorAndLoginRequiredMixin' 对象不可调用

Answer 1

您需要为此使用class based view：

from django.views.generic.edit import UpdateView


class AgentUpdateView(OrganisorAndLoginRequiredMixin, UpdateView):
    model = Agent
    template_name = 'template.html'
    form_class = AgentModelForm
