Question

我以前在序列化器中验证模型的输入，但是不得不使用从AbstractUser继承的属性更改为模型中的验证。

我认为我目前有以下内容：

class SetUserProfileView(generics.UpdateAPIView):
    """
    Use this endpoint to change user profile.
    """
    serializer_class = settings.SERIALIZERS.user_update_profile
    permission_classes = [permissions.IsAuthenticated]

    def get_object(self):
        return self.request.user

    def patch(self, request):
        testmodel = self.get_object()
        serializer = self.serializer_class(testmodel, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return Response(data=serializer.data, status=status.HTTP_200_OK)
        return Response(data=serializer._errors, status=status.HTTP_400_BAD_REQUEST)

但是如果我为角色发送长度为零的字符串，它将返回状态200并且不会更新角色字段

尽管事实上在models.py中角色存在约束，该字段必须位于ROLE_CHOICES

如何使用模型中的验证来更新视图以验证模型中的数据正确？我找不到

型号：

class SeaUser(AbstractUser):
    ...
    SARGENT_PEPPER = 'SGT'
    COLENAL_MUSTARD = 'COL'
    OTHER = 'OTH'
    ROLE_CHOICES = (
        (SARGENT_PEPPER, _('sargent')),
        (COLENAL_MUSTARD, _('colenal')),
        (OTHER, _('Other')),
    )
    role = models.CharField(_('Role'), max_length=3, choices=ROLE_CHOICES, default=CREW)

role必须是3个值之一。我用以下方法对此进行测试：

def test_update_user_no_role(self):
    payload = {"first_name": "foo",
        "last_name": "bar",
        "role": "",
        "preferred_timezone": "UTC"
    }
    response = self.request_update_user(payload)
    modified_user = self.user_model.objects.get(username=self.user_details['username'])

    print('mofified role: ', modified_user.role)

    self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST)
    self.assertEqual(self.user.role, modified_user.role)

序列化器：

class SeaUserCreateSerializer(UserCreateSerializer):
    class Meta:
        model = User
        fields = ('id',...,'role', 'gdpr',..)

    def validate_gdpr(self, value):
        if not validate_user_gdpr(value):
            raise serializers.ValidationError("GDPR must be accepted.")
        return value

视图：

补丁请求中的零长度字符串尽管经过验证仍返回状态200
