如何使用 Django RF 修补 Django 的用户模型?

Question

我有包含phone，profile_photo和Django默认用户模型的一些字段，如first_name，last_name，email的用户配置文件模型，我正在尝试更新其中一些字段。

models.py

class UserProfile(models.Model):
user = models.ForeignKey(User, verbose_name="User")
phone = models.CharField(max_length=16, verbose_name="Phone")
profile_photo = models.ImageField(null=True, blank=True, upload_to=user_directory_path, verbose_name="Profile Photo")

serializers.py

class UserSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ('url', 'first_name', 'last_name', 'email')
class UserProfileSerializer(serializers.ModelSerializer):
user = UserSerializer(partial=True)
class Meta:
model = UserProfile
fields = '__all__'
def create(self, validated_data):
user_profile = UserProfile.objects.create(**validated_data)
return user_profile

views.py

class UserProfileViewSet(viewsets.ModelViewSet):
queryset = UserProfile.objects.all()
serializer_class = UserProfileSerializer
authentication_classes = (TokenAuthentication,)
@detail_route(methods=['PATCH'], url_path='update-partial')
def user_profile_update_partial(self, request, pk=None):
profile = UserProfile.objects.get(id=pk)
serializer = self.get_serializer(profile, data=request.data, partial=True)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_202_ACCEPTED)
else:
return Response(status=status.HTTP_400_BAD_REQUEST)

如果我使用此@detail_route发送profile_photo、phone、first_name或last_name数据，我只能更新电话和profile_photo字段。profile_photo数据未发送时也收到错误请求错误。

如何使用PATCH方法实现partial_update？

Answer 1

class UserProfileViewSet(viewsets.ModelViewSet):
queryset = UserProfile.objects.all()
serializer_class = UserProfileSerializer
authentication_classes = (TokenAuthentication,)
def partial_update(self, request, *args, **kwargs):
profile = self.get_object()
serializer = self.get_serializer(profile, data=request.data, partial=True)
if serializer.is_valid():
user_serializer = UserSerializer(profile.user, data=request.data, partial=True)
if user_serializer.is_valid():
user_serializer.save()
serializer.save()
return Response(serializer.data, status=status.HTTP_202_ACCEPTED)
else:
return Response(data=user_serializer.errors, status=status.HTTP_400_BAD_REQUEST)
else:
return Response(data=serializer.errors,status=status.HTTP_400_BAD_REQUEST)

Q1：如何实施PATCH方法？

A1：覆盖partial_update方法。

Q2：如何更新first_name或last_name？

A2：使用另一个名为UserSerializer的序列化程序更新它。(如果要更新密码，则需要使用make_password方法创建编码密码，然后再将原始密码保存到数据库)
