The No-No SQL Way of populating Select Elements' Options Values

In a previous tip here, I showed how you can insert values into a MongoDB ("No SQL") Collection and then read them out using Meteor's Spacebars template language to populate a Select elements' Options values. This tip is similar but, instead of storing the data in and retrieving it out of a MongoDB Collection, it is stored/retrieved from a .json file. Here are the steps to do that:

First, put some data into a file, perhaps named settings.json, that resides directly beneath your project folder:

{"public" : { "uccampus": [ {"name":"UC Santa Cruz"}, {"name":"UC Berkeley"}, 
{"name":"UC Davis"}, {"name":"UC Irvine"}, {"name":"UC Los Angeles"}, 
{"name":"UC Merced"}, {"name":"UC Riverside"}, {"name":"UC San Diego"}, 
{"name":"UC San Francisco"}, {"name":"UC Santa Barbara"} ] }}
}

Second, add a helper for the Template in which the Select element resides, like so:

Template.tblTravelerInfo2.helpers({
    uccampus: function(){
        return Meteor.settings.public.uccampus;
    }
});

Third, add this to the HTML for that Select element (instead of things like "<option value="dp">Duckbilled Platypus</option>"):

{{#each uccampus}}
  <option>{{name}}</option>
{{/each}}

Note: When using this code, and running your Meteor app from its directory in the console, it is not enough to simply enter "meteor run" or "meteor". You need to enter "meteor --settings settings.json" (where "settings.json" is the name of the file containing the json data); and the said json file must reside directly beneath your project's folder - not in a subfolder.
