Remote method for album?

I haven't actually tried it yet. . . trying to come up with something that fits the context & makes sense. I find the static "CoffeeShop.status" example confusing, as I think most people would assume as I did: that the method checks the status of a particular coffeeshop (instance), whereas in fact it just checks whether the current time is between a hardcoded range.

Instance methods require a bit more configuration (maybe?) but they are much easier to understand the purpose of IMO.

/albums/123/complete 👉 75

Anyway here it is! Alternately it could just be a "say Hi" type method, but I think for the slides if we're going with "band app" from start to finish it would be confusing to introduce a new, different model while introducing model features.

I am wondering if it wouldn't be easier (at least in the slides) to push remote methods further back, after attendees can see the basic scaffolded stuff in action, see relationships, see how far you can get without customizing.

'use strict';

module.exports = function(Album) {
/**
 * reports how complete an album record is based on not-empty fields
 * returns number between 0 and 100
 * @param {Function(Error, number)} callback
 */
  Album.prototype.percentComplete = function(callback) {
    var numFields = 5;
    var fieldsComplete = 1; // assume title is complete

    if (this.year) fieldsComplete++;
    if (this['record-label']) fieldsComplete++;
    if (this.artwork) fieldsComplete++;
    if (this.tracks.length && this.tracks.length > 0) fieldsComplete++;

    callback(null, Math.round((fieldsComplete / numFields) * 100));
  };

  Album.remoteMethod('percentComplete', {
    isStatic: false,
    description: 'Get % of album fields completed',
    http: {
      path: '/complete',
      verb: 'get',
      status: 200
    },
    returns: {root: true, type: 'number'},
  });
};
