在流星中发布具有多个嵌套子文档的复合

Question

我正在使用meteor.js。我有三个收藏板，阵容

Boards : 
 {
 "_id": ObjectId("su873u498i0900909sd"),
  "locked": NumberInt(0),
 "board_name": "Legends",
  "description": "legends of the world",
   "apartments":  [{id:ObjectId("su873u498i0900909sd"),"val":'sdfs','lineup':[ObjectId("su873u498i0900f09sd"),ObjectId("su873u498i0900f09sd")]},{id:ObjectId("s78898973u498i0900909sd"),"val":'sdfs','lineup':[ObjectId("su873u498i0900f09sd"),ObjectId("su873u498i0900f09sd")]}],
  "cost": NumberInt(1),
 "image": "1389249002691_indexhj.jpeg",
"creator": ObjectId("52ce317994acdcee0fadc90c")
}


 lineup:
 {
  "_id": ObjectId("su873u498i0900f09sd"),
 "uid": ObjectId("su873u498i0900909sd"),
  sname:"hjjj"
 }

我如何使用发布合成来迭代板中的公寓字段，然后使用公寓中的阵容从阵容集合中查找数据

Answer 1

您要做的是加入数据，您可以在Meteor.publish的服务器上通过基于{lineup _id来查询apartments 1}}，然后使用here所述的transform函数。
