django - 禁用在 django rest 框架中创建嵌套对象

Question

你好，

你能帮我怎么做禁止创建嵌套对象 ?

我有这样的序列化程序:
(员工拥有团队的外键)

class TeamSerializer(serializers.ModelSerializer):
    class Meta:
        model = Team
        fields = ('id', 'name')
class EmployeeSerializer(serializers.ModelSerializer):
    class Meta:
        model = Employee
        fields = ('id', 'name', 'surname', 'team')
        depth = 1

或者可以是:

class EmployeeSerializer(serializers.ModelSerializer):
    team = TeamSerializer()
    class Meta:
        model = Employee
        fields = ('id', 'name', 'surname', 'team')

当我发布 json 时(创建员工)

{
    name: "name",
    surname: "surname",
    team: {
           id: 1,
           name: "Web Team"
          }
}

对象员工创建，但对象团队...
有什么方法可以禁用与员工一起创建团队对象吗？
我只想创建员工并将选定的团队(当前在数据库中)设置为员工

在 GET (list) 上，我希望能够检索
数据如:

{
 name: "name",
 surname: "surname",
 team: {
    id: 1,
    name: "Web Team"
 }

不是这样的

{
 name: "name",
 surname: "surname",
 team: 1
}

有没有办法在 django rest 框架中做到这一点(我也使用 angular)

问候

更新

目前的序列化程序:

class TeamSerializer(serializers.ModelSerializer):
    class Meta:
        model = Team

class EmployeeSerializer(serializers.ModelSerializer):
    team = TeamSerializer()

    class Meta:
        model = Employee

我不能使用 serializers.RelatedField() 因为它只返回 unicode 我需要“id”和“name”(我想)

这是我的 POST json: ( Restangular.all('employee').post(data) )

data: {
        name: "emp1",
        photo: "",
        skype: "",
        surname: "qweqwe",
        team: {
              id: 1,
              name: "Web",
        }
}

和 DRF 返回 json:

employee: {
    id: 2,
    name: "emp1",
    photo: "",
    skype: "",
    surname: "qweqwe",
    team: {
        id:3, <-- NEW ID!
        name: "Web"
    }   
}

所以是的，我确信创建了新的团队对象。所以现在怎么办 ？:)

Answer 1

我发现 ModelSerializer.to_native()和 ModelSerializer.from_native()在最新版本的 DRF 中不存在。我从公认的解决方案中提出了以下内容:

class PlayerSerializer(serializers.ModelSerializer):
    class Meta:
        model = Player
        fields = ('id', 'name', 'team')

    def to_internal_value(self, data):
        # If team is not a dict, such as when submitting via the Browseable UI, this would fail.
        try:
            data['team'] = data['team']['id']
        except TypeError:
            pass
        return super(PlayerSerializer, self).to_internal_value(data)

    def to_representation(self, instance):
        return ReadPlayerSerializer(instance).data


class ReadPlayerSerializer(serializers.ModelSerializer):
    team = TeamSerializer()

    class Meta(PlayerSerializer.Meta):
        pass

实际上，似乎 from_native现在是 to_representation , 和 to_native是不是 to_internal_value
