流星SimpleSchema插入嵌套对象

Question

I have the following collection which has a nested object address which is defined using the Collection2 Meteor Package. I am unable to insert the data for this nested object...

Sample data

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
}];

Collection definition

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);

Routine

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

The Problem

The console logs out the location address details object fine but, my MongoDb collection of inserted documents is empty for address? I've tried a multitude of things, including doing an update after the initial insert (which is far from ideal).

Can anyone explain why this nested object isn't being inserted and what is required to fix it?

Thanks

Use the publish-counts package to subscribe a count in meteor:

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

Once you've subscribed to 'getLocationCounts', you can call Counts.get('locations-counter') to get the value of the counter, reactively.

This function will always return an integer, 0 is returned if the counter is neither published nor subscribed to.

// 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);
    });
}
