Moongose模式引用的是旧的已删除模式

Question

我是Mongoose的新手，在尝试向架构中添加属性时遇到了很多麻烦。我忘了在架构中添加一些密钥，现在当我尝试更新架构时，返回的文档是我删除的旧架构

我尝试在架构上使用add（）方法，但该方法无效。我还尝试将配置文件制作成自己的Schema，并让其他UserInfoSchema像profile [ProfileSchema]一样引用它，但该配置无法正常工作。删除数据库无效。

我想添加

profile: {
     website: String,
     bio: String
}

到下面的架构代码

const userInfoSchema = new Schema({
    username: String,
    display_image: String,
    posts: [{
        post_id: String,
        post_caption: String,
        image: String,
        image_id: String,
        comments: [{
            username: String,
            user_id: String,
            date: { type: Date, default: Date.now },
            comment: String,
            user_display_image: String
        }],
        timestamp: String,
        items: [{
            category: String,
            name: String,
            price: String,
            stores: Array,
            online_link: String,
            description: String
        }]
    }],
    other_posts: [{ post_id: String, image: String }],
    followers: [Array],
    boards: [{
        id: String,
        name: String,
        display_image: String,
        user: String,
        images: [{
            username: String,
            post: {
                image: String,
                image_id: String
            }
        }]
    }],
    "notifications": [],
    "posts_liked": [{
        username: String,
        id: String,
        post_id: String
    }],
    "feed": [{
        username: String,
        id: String,
        post_id: String
    }]


});

谢谢
