Mongoose - 如何向 ObjectId 引用的数组添加额外的键？

Question

var conversationSchema = new Schema({
    created: { type: Date, default: Date.now },
    updated: { type: Date, default: Date.now },
    recipients: [{ type: Schema.ObjectId, ref: 'User' }],
    messages: [ conversationMessageSchema ]
});
mongoose.model('Conversation', conversationSchema);

在上面的示例中，您将如何在收件人数组中添加额外的属性，例如...状态？

I.E.收件人：

[{ _id: { 
    type: Schema.ObjectId, 
    ref: 'User'
  }, 
  status { 
    type: String
  } 
}]

像这样^?

谢谢

你可以这样做

 var conversationSchema = new Schema({
    created: { type: Date, default: Date.now },
    updated: { type: Date, default: Date.now },
    recipients: [
      name:{ type: Schema.Types.ObjectId,  ref: 'User' },
      status { type: String}
    ],
    messages: [ conversationMessageSchema ]
});
mongoose.model('Conversation', conversationSchema);
