貓鼬多對多關系

Question

我是初學者Node.JS和Mongoose程序員。 到目前為止，我已經創建了一個非常簡單的博客，其中包含3個模型-文章，用戶，類別，並且一切正常。 現在，我想創建評論。 因此，我希望每個用戶都可以發表評論，每個文章也都可以發表評論。 我該怎么做以及如何在控制器中表示邏輯以進行交互：

let articleSchema = mongoose.Schema (
{
    author: {type: ObjectId, ref: 'User'},
    title: {type: String, required: true },
    content: {type: String, required: true },
    category: {type: ObjectId, ref: 'Category', required: true},
    date: {type: Date, default: Date.now() },
}
);

let userSchema = mongoose.Schema(
{
    email: {type: String, required: true, unique: true},
    passwordHash: {type: String, required: true},
    fullName: {type: String, required: true},
    salt: {type: String, required: true},
    articles: [{type: ObjectId, ref: 'Article'}],
    roles: [{type: ObjectId, ref: 'Role'}]
}
);

let categorySchema = mongoose.Schema (
{
    name: {type: String, required:true},
    articles: [{type: ObjectId, ref: 'Article'}]
}
);

創建將引用作者和文章的評論架構：

let commenSchema = mongoose.Schema (
{
    author: {type: ObjectId, ref: 'User', required: true},
    content: {type: String, required: true },
    article: {type: ObjectId, ref: 'Article', required: true},
    date: {type: Date, default: Date.now() },
});
