如何使用Django-Rest-Framework序列化用户组

Question

我正在尝试使用Django REST框架获得用户组,但只有我得到的是名为"groups"的空字段.

这是我的UserSerializer:

class UserSerializer(serializers.ModelSerializer):    
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'is_staff', 'groups')

任何想法如何获得用户组数据？

提前致谢

Answer 1

您必须指定它是嵌套关系:

class GroupSerializer(serializers.ModelSerializer):    
    class Meta:
        model = Group
        fields = ('name',)

class UserSerializer(serializers.ModelSerializer):    
    groups = GroupSerializer(many=True)
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'is_staff', 'groups',)

像这样的东西应该有效。

from django.contrib.auth.models import Group


class UserSerializer(serializers.ModelSerializer): 
    groups = serializers.SlugRelatedField(
        many=True,
        read_only=True,
        slug_field='name',
     )  
 
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'is_staff', 'groups',)
