Populating Select Elements' Options Values with "lookup" data stored in your settings.json file in your Meteor apps

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.

Don't Neglect the Superhero's Superhero (After Meteor Man, of course)

I am in the process of morphing from a software developer into a portrayer of Mark Twain. My monologue (or one-man play, entitled "The Adventures of Mark Twain: As Told By Himself" and set in 1896) features Twain giving an overview of his life up till then. The performance includes the relating of interesting experiences and humorous anecdotes from Twain's boyhood and youth, his time as a riverboat pilot, his wild and woolly adventures in the Territory of Nevada and California, and experiences as a writer and world traveler, including recollections of meetings with many of the famous and powerful of the 19th century - royalty, business magnates, fellow authors, as well as intimate glimpses into his home life (his parents, siblings, wife, and children).

Peripatetic and picaresque, I have lived in eight states; specifically, besides my native California (where I was born and where I now again reside) in chronological order: New York, Montana, Alaska, Oklahoma, Wisconsin, Idaho, and Missouri.

I am also a writer of both fiction (for which I use a nom de plume, "Blackbird Crow Raven", as a nod to my Native American heritage - I am "½ Cowboy, ½ Indian") and nonfiction, including a two-volume social and cultural history of the U.S. which covers important events from 1620-2006: http://www.lulu.com/spotlight/blackbirdcraven
