我有一个Mongoose Schema（约会），有两个reffield（发送者和接收者） . 两者都引用相同的Schema（用户） . 我试图使用mongoose-paginate插件填充这两个字段 .

约会架构片段 .

var paginate = require('mongoose-paginate');

var AppointmentSchema = new Schema({
  dateCreated: {type: Date, default: Date.now},
  sender: {type: ObjectId, ref: 'User'},
  receiver: {type: ObjectId, ref: 'User'},
  message: String,
  
  .........................
  
AppointmentSchema.plugin(paginate);

var Appointment = mongoose.model('Appointment', AppointmentSchema);
module.exports = Appointment;

用户架构片段 .

var UserSchema = new Schema({
  username: String,
  name: {
    first: String,
    middle: String,
    last: String
  },
  
  ..................
  
var User = mongoose.model('User', UserSchema);

module.exports = User;

mongoose paginate查询 .

Appointment.paginate({}, request.query.page, request.query.limit,
    function(error, pageCount, appointments, itemCount) {
      if (error) {
         return console.log('ERRRRRRRRRR'.red);
      } else {
        console.log(appointments);
        return response.render('message/inbox',
        {
          pageTitle: "Trash",
          messages: appointments,
          pageCount: pageCount,
          itemCount: itemCount,
          currentPage: currentPage
        });
      }
    }, {columns: {}, populate: 'receiver', populate: 'sender', sortBy: {title: -1}});

这工作正常但我想填充发送者和接收者字段 . 请问我该怎么做 . 我尝试在JSON中传递字段但是没有用 .

node.js express mongoose mongoose-populate

    我只是将一系列字段传递给 populate ，它就像一个魅力 .

    Appointment.paginate({}, request.query.page, request.query.limit,
    function(error, pageCount, appointments, itemCount) {
      if (error) {
         return console.log('ERRRRRRRRRR'.red);
      } else {
        console.log(appointments);
        return response.render('message/inbox',
        {
          pageTitle: "Trash",
          messages: appointments,
          pageCount: pageCount,
          itemCount: itemCount,
          currentPage: currentPage
        });
      }
    }, {columns: {}, populate: ['receiver', 'sender'], sortBy: {title: -1}});
