Question

我有一个 ProfileSerializer 是 ModelSerializer:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('first_name', 'last_name', 'email', 'password')

class ProfileSerializer(serializers.ModelSerializer):
    user = UserSerializer(required=True)

    def create(self, validated_data):
        user_data = validated_data.pop('user')
        user = User.objects.create_user(**user_data, username=validated_data.get('username'))
        profile = Profile.objects.create(user=user, **validated_data)
        return profile

    def update(self, instance, validated_data):
        instance.dob = validated_data.get('dob', instance.dob)
        instance.karma = validated_data.get('karma', instance.karma)
        instance.username = validated_data.get('username', instance.username)
        user_data = validated_data.pop('user')
        instance.user.first_name = user_data.get('first_name', instance.user.first_name)
        instance.user.last_name = user_data.get('last_name', instance.user.last_name)
        instance.user.email = user_data.get('email', instance.user.email)
        instance.user.username = instance.username
        new_password = user_data.get('password')
        if new_password:
            instance.user.set_password(new_password)
        instance.user.save()
        instance.save()
        return instance

    class Meta:
        model = Profile
        fields = '__all__'

而且，我有一个名为 DetailProfile 的视图，它是一个 RetrieveUpdateDestroyAPIView:

class DetailProfile(RetrieveUpdateDestroyAPIView):
    queryset = Profile.objects.all()
    serializer_class = ProfileSerializer
    lookup_field = 'username'
    lookup_url_kwarg = 'username'

问题是每当我发出 PUT 请求时，我都必须发送所有字段，包括密码。现在，我从 GET 请求中获得的密码是 hashed。因此，如果我在 PUT 请求中发送相同的 hashed 密码，密码将被替换为该字符串（看起来像这样 pbkdf2_sha2560000$v7HiZeWnhmQj$ftiQyZCjMJ6pa26P5w72wQZvn+goEB94/lKyJ8LeKrM=).

所以，我想发出 PATCH 请求而不发送密码。

您可以重写 put 方法并添加 partial 参数，这会启用部分更新逻辑：

class DetailProfile(RetrieveUpdateDestroyAPIView):
    queryset = Profile.objects.all()
    serializer_class = ProfileSerializer
    lookup_field = 'username'
    lookup_url_kwarg = 'username'

    def put(self, request, *args, **kwargs):
        kwargs['partial'] = True 
        return self.update(request, *args, **kwargs)

BTW 补丁请求也可用于 RetrieveUpdateDestroyAPIView。因此，如果您同时需要 PUT 和 PATCH，则可以在不覆盖 put() 方法的情况下使用它们。
