链接2个mongoose模式

Question

我有两个模式,a Team和a Match.我想用它Team Schema来识别队中的队伍Match Schema.到目前为止,这是我的Team和Match JS文件.我想将Team Schema链接到我的Match Schema,以便我可以简单地识别主队或客队,这样我就可以在Match Schema中存储一个实际的Team对象.

这样我可以参考主队例如Match.Teams.home.name = England(这只是一个例子)

Team.js

'use strict';

var util = require('util');
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var validatePresenceOf = function(value){
  return value && value.length; 
};

var getId = function(){
  return new Date().getTime();
};

/**
  * The Team schema. we will use timestamp as the unique key for each team
  */
var Team = new Schema({
  'key' : {
    unique : true,
    type : Number,
    default: getId
  },
  'name' : { type : String,
              validate : [validatePresenceOf, 'Team name is required'],
              index : { unique : true }
            }
});

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

这就是我想用Match.js做的事情

'use strict';

var util = require('util');
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var TeamSchema = require('mongoose').model('Team');

var validatePresenceOf = function(value){
  return value && value.length; 
};

var toLower = function(string){
  return string.toLowerCase();
};

var getId = function(){
  return new Date().getTime();
};

/**
  * The Match schema. Use timestamp as the unique key for each Match
  */
var Match = new Schema({
  'key' : {
    unique : true,
    type : Number,
    default: getId
  },
  'hometeam' : TeamSchema,
  'awayteam' : TeamSchema
});

module.exports = mongoose.model('Match', Match);

您的解决方案：使用实际架构，而不是使用该架构的模型：

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

到

module.exports = {
    model: mongoose.model('Team', Team),
    schema: Team
};

然后直接var definition = require('path/to/js');使用而definition.schema不是模型
