Meteor SimpleSchema 插入嵌套对象

Question

我有以下集合，其中有一个嵌套对象 address，它是使用 Collection2 Meteor 包定义的。我无法为这个嵌套对象插入数据...

示例数据

var addresses = [{
    "venue": "Kirkstall Abbey",
    "street": "Kirkstall Lane",
    "city": "Leeds",
    "county": "West Yorkshire",
    "postcode": "LS6 3LF"
},{ 
    "venue": "Headingley High School",
    "street": "",
    "city": "Leeds",
    "county": "West Yorkshire",
    "postcode": "LS6 7QR"
}];


var locations = [{
    "name": "Kirkstall Abbey",
    "address": addresses[0],
    "image": null,
    "active": true
},{
    "name": "Headingley",
    "address": addresses[1],
    "image": null,
    "active": true
}];

集合定义

ClassLocation = new Mongo.Collection("class-location");

Schemas.ClassLocation = new SimpleSchema({
    name: {
      type: String,
      optional: true
    },
    address: {
      type: Object
    },
    image: {
      type: String,
      optional: true
    }
    active: {
      type: Boolean,
      optional: true
    }
});

ClassLocation.attachSchema(Schemas.ClassLocation);

日常

if(ClassLocation.find().count() === 0) {
  _.each(locations, function (location) {
    console.log(location.address);
    ClassLocation.insert(location);
  });
}

问题

控制台可以很好地注销位置地址详细信息对象，但是，我的 MongoDb 插入文档集合的地址是空的？我已经尝试了很多事情，包括在初始插入后进行更新（这远非理想）。

谁能解释为什么这个嵌套对象没有被插入以及需要什么来修复它？

谢谢

使用publish-counts包在meteor中订阅一个计数：

// server: publish the current size of a collection
Meteor.publish('getLocationCounts', function() {
    Counts.publish(this, 'locations-counter', ClassLocation.find());
});

订阅 'getLocationCounts' 后，您可以调用 Counts.get('locations-counter') 以被动地获取计数器的值。

此函数将始终 return 一个整数，如果计数器既未发布也未订阅，则 return 为 0。

// client: get the count value reactively
var exists = (Counts.get('locations-counter')=== 0);
if(exists) {
    _.each(locations, function (location) {
        console.log(location.address);
        ClassLocation.insert(location);
    });
}
