Basic Syntax

Locations = new Meteor.Collection2('Locations', {
	schema: {
		country: {
      type: String,
      label: 'Country',
      max: 50
    },
    city: {
      type: String,
      label: 'City',

// TravelController.show was commented out when using this controller
ShowTravelController = ApplicationController.extend({
	waitOn: function() {
		var id = this.params._id;
		return [Meteor.subscribe('singleTravelRequest', id)];
	},

	action: function() {
	  // tried this one too
		// this.waitOn = Meteor.subscribe('singleTravelRequest', this.params._id);
