在 GET 中隐藏密码字段，但在 Django REST Framework 中隐藏密码字段，其中序列化程序中的 depth=1

Question

我有 2 个模型：User 和 UserSummary。UserSummary 有一个 User 的外键。我只是注意到，如果我depth= 1在 内设置UserSummarySerializer，则密码字段将包含在输出中。它被散列，但最好还是排除这个字段。

为了隐藏密码字段，我刚刚在序列化程序中明确设置了用户字段，就像这样：

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

这种做法的缺点是，在创建新用户时，POST 请求中不再提供字段密码。

如何password在 UserSummary 的 GET 请求中隐藏该字段，但在 User 的 POST 请求中显示它？

Answer 1

这里的技巧是在“字段”元组中包含“密码”字段，以便密码显示在“GET”和“POST”中，然后添加“extra_kwargs”以强制“密码”字段仅出现在“POST”中形式。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}}

当您将所有功能序列化器都放在一个时，这很复杂，我会UserCreateSerializer在这种情况下创建一个：

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

然后你可以UserCreateSerializer在你的UserCreateAPIView.

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
