Related items in Meteor

Question

I have groups and items and the items are related to specific groups. At the "detail page" of a group I want to see all the items belonging to the specific group.

I've tried this

Router.route('/group/:_id', {
  name: 'group',
  template: 'group',
  waitOn: function () {
    return this.subscribe("groups", this.params._id);
  },
  data: function () {
    return {
      group: Groups.findOne(this.params._id);
      items: Items.find({groupId: this.params._id}),
    }
  }
});

But what should waitOn look like if it should both wait for the specific group AND the items belonging to the group?

You can return an array of subscriptions to wait on:

waitOn: function () {
    return [
        Meteor.subscribe("groups", this.params._id),
        Meteor.subscribe("items", this.params._id)
    ]
}

Yup. I really wish the Iron Router docs would just create an example code section with this because it's not at all obvious from the docs. – fuzzybabybunny Dec 17 '14 at 08:37

You can either have another publish function

 Meteor.publish('relatedItems', function (groupId) {
   return Items.find({groupId: groupId});
 });

and wait for the two subscriptions

 waitOn: function () {
   return [
     Meteor.subscribe("groups", this.params._id),
     Meteor.subscribe("relatedItems", this.params._id)
   ];
 },

or you can add to your existing publication like this:

 Meteor.publish('groups', function (groupId) {
   return [
      Groups.find({_id: groupId}),
      Items.find({groupId: groupId}),
   ];
 });
