在GET中隐藏password字段，而不是在Django REST框架中隐藏POST，其中serializ中的depth=1

Question

我有两个模型：用户和用户摘要。UserSummary具有User的外键。我刚刚注意到，如果我在UserSummarySerializer内设置depth= 1，那么输出中将包含密码字段。它是散列的，但最好还是排除这个字段。在

为了隐藏password字段，我在序列化程序中显式设置了user字段，如下所示：

class UserSerializer(serializers.ModelSerializer):
    """A serializer for our user profile objects."""

    class Meta:
        model = models.User
       extra_kwargs = {'password': {'write_only': True}}
        exclude = ('groups', 'last_login', 'is_superuser', 'user_permissions', 'created_at')

    def create(self, validated_data):
        """Create and return a new user."""

        user = models.User(
            email = validated_data['email'],
            firstname = validated_data['firstname'],
            lastname = validated_data['lastname'],
            mobile = validated_data['mobile']
        )

        user.set_password(validated_data['password'])
        user.save()

        return user


class UserSummarySerializer(serializers.ModelSerializer):
    user = UserSerializer()

    class Meta:
        model = models.UserSummary
        fields = '__all__'
        depth = 1

这种方法的缺点是，在创建新用户时，POST请求中的字段密码不再可用。在

如何隐藏UserSummary的GET请求上的password字段，而在User的POST请求中显示它？在

Answer 1

class UserSerializer(serializers.ModelSerializer):

    class Meta:
        model = User

    def to_representation(self, obj):
        rep = super(UserSerializer, self).to_representation(obj)
        rep.pop('password', None)
        return rep

Answer 2

这里的诀窍是在“fields”元组中包含“password”字段，以便密码同时显示在“GET”和“POST”中，然后添加“extra_kwargs”以强制“password”字段仅以“POST”形式出现。代码如下：

class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email',
              'is_active', 'is_staff', 'is_superuser', 'password',)

        # These fields are displayed but not editable and have to be a part of 'fields' tuple
        read_only_fields = ('is_active', 'is_staff', 'is_superuser',)

        # These fields are only editable (not displayed) and have to be a part of 'fields' tuple
        extra_kwargs = {'password': {'write_only': True, 'min_length': 4}}

当您将所有函数序列化器都设置为一个时，这很复杂，在这种情况下，我将创建一个UserCreateSerializer：

class UserCreateSerializer(serializers.ModelSerializer):
    """A serializer for our user profile objects."""

    class Meta:
        model = models.User
        extra_kwargs = {'password': {'write_only': True}}
        fields = ['username', 'password', 'email', 'firstname', 'lastname', 'mobile'] # there what you want to initial.

    def create(self, validated_data):
        """Create and return a new user."""

        user = models.User(
            email = validated_data['email'],
            firstname = validated_data['firstname'],
            lastname = validated_data['lastname'],
            mobile = validated_data['mobile']
        )

        user.set_password(validated_data['password'])
        user.save()

        return user

然后您可以在您的UserCreateAPIView中使用UserCreateSerializer。在
