Django AttributeError:'str'对象没有属性'model'

Question

我有以下表格;

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

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.但相反,我坚持AttributeError at /station/2/removemember,对应于第二个视图的URL,'str' object has no attribute 'model'

Answer 1

这是因为你指定了:

queryset=""

在你的形式.请改用查询集(例如queryset=Member.objects.all()).
