DbRef 与猫鼬 - 猫鼬-dbref 还是填充?

问题描述

我有以下两个架构:

公司活动:

var companyEventSchema = new Schema({
    name : String,
    description
    date : Date,
    attendees : [ { type : Schema.ObjectId, ref : 'Member' } ],
]});

和会员

var memberSchema = new Schema({
    name : String,
    emailAddress: String,
    password :String,
    created: { type: Date, default: Date.now }
});

我从 companyEventSchema 中引用 Member 的方式是否正确?我正在尝试做一些很长的 dbref 行.

Is the way i've ref'd Member from companyEventSchema correct?I'm trying to do something a long the lines of a dbref.

我看到有一个单独的项目...mongoose-dbref

I saw theres a separate project for that though... mongoose-dbref

然而，猫鼬文档说上面提供了类似dbref的功能"

However, the mongoose docs say the above provides "dbref like functionality"

哪个更有效?

推荐答案

你只需要使用一个实际的 DBRef(和 mongoose-dbref)用于字段可以包含引用可能多个集合中的文档的 ObjectId 的情况.DBRef 是 ObjectId、集合名称和可选数据库名称的元组.

You only need to use an actual DBRef (and mongoose-dbref) for the case where a field can contain ObjectIds that reference documents in potentially more than one collection. A DBRef is a tuple of an ObjectId, a collection name, and an optional database name.

Mongoose ref: 字段仅包含一个 ObjectId，并且 Mongoose 架构定义了 ObjectIds 引用的一个集合.

Mongoose ref: fields, however, contain just an ObjectId and it's the Mongoose schema that defines what one collection the ObjectIds reference.

因此 Mongoose ref: 字段效率更高，应始终使用，除非您需要 DBRef 提供的多集合引用支持.

So Mongoose ref: fields are more efficient and should always be used unless you need the multi-collection reference support that DBRef provides.
