Question

我创建了以下架构：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var Player = require('./player');

var gameSchema = new Schema({

  created_at: Date,
  nrOfCards: String,
  players: [{
          sticks: String,
          player: {
              type: mongoose.Schema.Types.ObjectId,
              ref: 'Player'
          }
      }],

});

var Game = mongoose.model('Game', gameSchema);

保存部分工作正常，保存的对象可能如下所示：

    "_id": "57dd11aca0c36114588fd250",
    "nrOfCards": "3",
    "__v": 0,
    "players": [
      {
        "_id": "57d415e527c20f3ed2416e05",
        "age": "33"
      },
      {
        "_id": "57d417df2186d53f3d49c996",
        "age": "73"
      },
      {
        "_id": "57d41d85ec315d4234010c7d",
        "age": "20"
      }
    ]
  },

在保存了一个对象之后，我希望在填充了player-field的情况下返回它。这是我的尝试：

   app.post('/api/games', function(req, res) {

        Game.create({
            players : req.body.activePlayers,
            nrOfCards: req.body.nrOfCards,
        }, function(err, game) {
            if (err) {
              res.send(err);
            } else {
              Game.findOne(game)
                  .populate('players.player')
                  .exec(function (err, newgame) {
                    if (err) return handleError(err);
                    console.log(newgame);
                      res.json(newgame);
                  });
            }
        });
    });

认为.populate('players.player')应该可以解决这个问题，但我只是接收了包含_id player #div1{ height:50px; overflow:hidden; } #div1:hover{ height:300px; -moz-transition: .4s all ease-in-out; -ms-transition: .4s all ease-in-out; -webkit-transition: .4s all ease-in-out; -o-transition: .4s all ease-in-out; }的未填充字段。

小贴士表示赞赏。谢谢！

使用

player: { type: Schema.Types.ObjectId, ref: 'Player' }

进入您的架构。
