python - Django AttributeError:“str”对象没有属性“model”

我有以下表格；

class RemoveMemberForm(Form):
    member = forms.ModelChoiceField(queryset="",
                                  empty_label='Choose a Member',
    )

以及以下观点；

class StationHome(View):
    def get(self, request, pk):
        station = Station.objects.get(pk=pk)
        channels = Channel.objects.filter(station=station)
        members = station.members.all()
        form1 = AddMemberForm()
        form2 = RemoveMemberForm()
        form2.fields['member'].queryset = station.members.all()
        return render(request,
                      "home_station.html",
                      {"station":station,
                       "form1":form1,
                       "form2":form2,
                       "channels":channels,
                       "members":members,
                   },
                  )

class MemberRemove(View):
    def post(self, request, pk):
        form = RemoveMemberForm(request.POST)
        if form.is_valid():
            Station.objects.get(pk=pk).members.remove(
                form.cleaned_data['member']
            )
            return HttpResponseRedirect(reverse("home_station",
                                        kwargs={'pk':pk},
                                    )
                            )

我要做的是让第二个视图删除所选成员并重定向到第一个视图。But instead I'm stuck at AttributeError at /station/2/removemember, the URL corresponding to the second view, 'str' object has no attribute 'model'

最佳答案

This is because you specified:

queryset=""

以你的形式。改为使用queryset（例如queryset=Member.objects.all()）。
