Mongo模型可以自我参考吗 [英] Can a Mongo model self reference

问题描述

我有一个这样的模型:

var userSchema = new mongoose.Schema({
  _id: { type: Schema.ObjectId },
  email: { type: String, unique: true },
  ipAddress: { type: String },
  referals: [{
    type: mongoose.Schema.Types.ObjectId, ref: 'User'
  }],
  redeem_token: {type: String, unique: true}
});

var User = mongoose.model('User', userSchema);

这可以工作吗?该用户需要参考其他用户.这是为了跟踪注册推荐人.然后，我想使用.Populate，并在引荐中扩展用户[]

Can this work? The user, needs to have a reference to other users. It's to track signup referrals. I want to then use .Populate and expand the users in the referals[]

推荐答案

我正在使用猫鼬.这对我有用，我只是使用this作为对模型的引用. 我有一个Comment模型.评论中的回复也可以为Comment.

I'm using Mongoose. This works for me, I'm simply using this as a reference to the model. I have a Comment model. Comments can have a reply that is also Comment.

    var Comment = new mongoose.Schema({
      id: { type: ObjectId, required: true },
      comment:    { type: String },
      replies:    [ this ],
    });
