Python 如何在django中自定义onetomany关系的序列化程序数据

我为图像模型定义序列化程序，并在调用后序列化程序时调用它以立即提供数据。这个操作没有问题，但我并没有按照我的要求提供json数据

现在我把它给你，就这样

{
        "pk": 0,
        "author": {
            "id": 0,
            "email": "",
            "username": "",
            "profile": "url",
            "following": 0,
            "followers": 0
        },
        "title": "",
        "text": "",
        "view": 0,
        "images": [
            {
                "image": "url"
            },
            {
                "image": "url"
            },
            {
                "image": "url"
            },
            {
                "image": "url"
            }
        ],
        "like_count": 0,
        "comment_count": 0,
        "liker": [
            0,
            0
        ],
        "tag": null,
        "created_at": "2020-10-06T21:46:48.039354+09:00"
    },

我想要这个

{
            "pk": 0,
            "author": {
                "id": 0,
                "email": "",
                "username": "",
                "profile": "url",
                "following": 0,
                "followers": 0
            },
            "title": "",
            "text": "",
            "view": 0,
            "images": [
                url,
                url,
                url,
                url
            ],
            "like_count": 0,
            "comment_count": 0,
            "liker": [
                0,
                0
            ],
            "tag": null,
            "created_at": "2020-10-06T21:46:48.039354+09:00"
        },

json将如何以我想要的方式出现？这是我的密码

序列化程序.py

您希望在

后序列化程序中使用而不是
图像序列化程序
：

类后序列化程序（serializers.ModelSerializer）：
...
images=serializers.SlugRelatedField（many=True，read\u only=True，slug\u field='image'））

我尝试了，但出现了错误“Image”对象没有属性“url”我的答案被编辑，
slug\u字段
应该是“Image”我尝试了，但出现了错误“Image”对象没有属性“url”我的答案被编辑，
