Question

我有一个mongodb文档“ team”，我想通过Nodejs-mongoose应用程序将Teammate推送到一个数组。

队友是具有一些附加属性的人员参考。假设额外的属性仅在Team文档中相关，因此我不想将其存储在person文档中。

问题是：推送未将所有预期的属性添加到团队文档中的队友数组。

预期的行为：人员对象引用，人员名称，人员roleInTeam和注释数据将添加到“团队”文档中的“队友”数组中。

相反，在更新/推送之后，Teammates数组仅包含人员参考及其名称。

我猜问题出在$ push语句周围，但是找不到正确的语句。请帮忙：）谢谢！

更新/推送后的结果小组文档：

{
"_id": {
    "$oid": "5b596eefa8b2793a642938be"
},
"teamTitle": "Team1",
"teammates": [
    {
        "_id": {
            "$oid": "5b596f13a8b2793a642938bf"
        },
        "name": "Leader John"
    },
    {
        "_id": {
            "$oid": "5b5970eba66ced0e580444fb"
        },
        "name": "Tester John "
    }
],
"date": {
    "$date": "2018-07-26T06:49:19.683Z"
},
"__v": 0
}

预期结果将是这样：

    ...
    "teammates": [
        {
            "_id": {
                "$oid": "5b596f13a8b2793a642938bf"
            },
            "name": "Leader John",
            "roleInTeam": "Leader",
            "comment": "Blackbelt tech lead"
        },
    ...

现在这是我的代码（我跳过了app.js，在这里不重要）

这是团队模式：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const TeamSchema = new Schema({
  teamTitle: {
    type: String,
    required: true
  },  
  teammates: [
                {
                    teammate: {
                    type: Schema.Types.ObjectId,
                    ref: 'persons'
                    },
                    name: {
                      type: String,
                      required: true                    
                    },
                    roleInTeam: {
                    type: String,
                    required: true
                    },
                    comments: {
                    type: String
                    }                    
                }
            ],
  date: { 
    type: Date,
    default: Date.now
  } 
});

module.exports = Team = mongoose.model('team', TeamSchema);

以下是在团队中引用的Person模式：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const PersonSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true 
  },
  date: {
    type: Date,
    default: Date.now
      }  
});

module.exports = Person = mongoose.model('persons', PersonSchema);

这是可以执行推送的api代码：

const express = require('express');
const router = express.Router();
const mongoose = require('mongoose');
const Team = require('../../models/Team');
const Person = require('../../models/Person');

// @route   POST api/team/teammate
// @desc    Add one teammate to the team if not exists
router.post(
  '/teammate',  
  (req, res) => {

    const errors = {};

    //new teammate data
    const newTeammate = Person({
      _id:  mongoose.Types.ObjectId(),
      name: req.body.name,
      email: req.body.email     
    });

     Team.findOne({ "teammates.name": newTeammate.name}).then(team => 
      {
          if (team) {
            errors.name = 'There is a teammate with identical name';
            res.status(400).json(errors);
          } else 
            {
                newTeammate.save().then(newTeammate => {
                if (newTeammate) {                

                  Team.findOneAndUpdate(
                    { _id: req.body.id }, 
                    { $push: {  teammates: newTeammate, name: newTeammate.name, roleInTeam: req.body.roleInTeam, comment: req.body.comment  } }, 
                    { new: true }
                  ).then(team => res.json(team));
                }
              }).then(console.log('Teammate added'));               

            }                      
       });
  }
);

module.exports = router;
