Django restframework，extra_kwargs不工作

Question

我有自定义用户模型。我已经为用户注册创建了一个api。以下是我的序列化器。

class UserSerializer(serializers.ModelSerializer):
    email = serializers.EmailField(
        required=True,
        validators=[
            UniqueValidator(queryset=get_user_model().objects.all())
        ]
    )
    password = serializers.CharField(min_length=8)

    class Meta:
        model = get_user_model()
        fields = ('email', 'password')
        extra_kwargs = {'password': {'write_only': True}, }

    def create(self, validated_data):
        email = validated_data.pop('email')
        password = validated_data.pop('password')
        user = get_user_model().objects.create_user(email, password, **validated_data)
        return user

以下是我的观点：

class Registration(generics.CreateAPIView):
    serializer_class = UserSerializer
    queryset = get_user_model().objects.all()

有两个输入email和password。 password字段以write_only字段的形式给出。但是在创建用户之后，api会返回哈希密码。如何防止返回密码？

如果使用extra_kwargs尝试这样做，则无需在序列化程序中明确声明该字段：

class UserSerializer(serializers.ModelSerializer):
    email = serializers.EmailField(
        required=True,
        validators=[
            UniqueValidator(queryset=get_user_model().objects.all())
        ]
    )

    class Meta:
        model = get_user_model()
        fields = ('email', 'password')
        extra_kwargs = {'password': {'write_only': True, 'min_length': 8}}
