Question

我编写了一个Django项目，并使用默认的Groups和Permissions。

当我列出或检索组时，数据如下：

{
    "id": 2,
    "name": "group02",
    "permissions": [
        22,
        23,
        24
    ]
}

我看不到permissions名称，users属于Group个实例。

如何优化此项以满足我的要求？

如果你想在dajngo shell中看到结果，那么你可以试试这个：User.objects.values('id','username','groups','groups__permissions')

如果您使用Django Rest Framework，则可以使用ModelSerializer，如下所示;

from django.contrib.auth.models import Group,Permission,User


class GroupSerializer(serializers.ModelSerializer):
    permissions = serializers.StringRelatedField(many=True)
    class Meta:
        model = Group
        fields = ('id','name','permissions')


class UserSerializer(serializers.ModelSerializer):
    groups = GroupSerializer(many=True)

    class Meta:
        model = User
        fields = ('id', 'username', 'groups')

预期输出：

[
    {
            "id": 49,
            "username": "jerinpetergeorge",
            "groups": [
                {
                    "id": 2,
                    "name": "NewGroup",
                    "permissions": [
                        "activity | activity | Can change activity"
                    ]
                },
                {
                    "id": 1,
                    "name": "test",
                    "permissions": [
                        "activity | activity | Can add activity",
                        "activity | activity | Can change activity",
                        "activity | activity | Can delete activity"
                    ]
                }
            ]
        },

    {
        ...
        ...
    }
]

如何在Django中自定义组？
