Python Django AttributeError，KeyError

这是我的

views.py

def new_note(request):
    form = NoteForm(request.POST, user=request.user)
    . . .
    return render(request, 'newNote.html', {'note_form': NoteForm, 'registered': registered})

class NoteForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        # self.user = kwargs.pop('user', None)
        self.user = kwargs.pop('user')
        # self.validate = kwargs.pop('validate', False)
        super(NoteForm, self).__init__(*args, **kwargs)
        groups = StudentGroup.objects.filter(id_nauczyciela=self.user.pk)
        # print(self.user.pk)
        self.fields['id_groups'].queryset = groups

    note_name = forms.CharField(label="Note name", required=True)

    class Meta:
        model = Note
        fields = ('id_groups', 'id_students', 'note_name')

这是我的

forms.py

def new_note(request):
    form = NoteForm(request.POST, user=request.user)
    . . .
    return render(request, 'newNote.html', {'note_form': NoteForm, 'registered': registered})

class NoteForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        # self.user = kwargs.pop('user', None)
        self.user = kwargs.pop('user')
        # self.validate = kwargs.pop('validate', False)
        super(NoteForm, self).__init__(*args, **kwargs)
        groups = StudentGroup.objects.filter(id_nauczyciela=self.user.pk)
        # print(self.user.pk)
        self.fields['id_groups'].queryset = groups

    note_name = forms.CharField(label="Note name", required=True)

    class Meta:
        model = Note
        fields = ('id_groups', 'id_students', 'note_name')

id\u组

是ModelChoseField

在这段代码中，我尝试获取记录的用户id

当我尝试使用它时，我得到了错误

KeyError'user'

，当我将

self.user=kwargs.pop（'user'）

更改为

self.user=kwargs.pop（'user'，None）

我得到了这样的错误

AttributeError:“非类型”对象没有属性“pk”

我绝对肯定

self.user.pk

返回的值是我所期望的

我的问题是如何处理这类错误？

您的渲染完全忽略了您提供的表单

return render(request, 'newNote.html', {'note_form': NoteForm, 'registered': registered})

应该是

return render(request, 'newNote.html', {'note_form': form, 'registered': registered})

这将解决您遇到的原始密钥错误问题，更改代码时发现的问题将需要不同的错误处理

self.user = kwargs.pop('user', None)
# self.validate = kwargs.pop('validate', False)
super(NoteForm, self).__init__(*args, **kwargs)

if self.user is not None:
    groups = StudentGroup.objects.filter(id_nauczyciela=self.user.pk)
    # print(self.user.pk)
    self.fields['id_groups'].queryset = groups
