[Patch][CLA] dojox/app: Support loading of models per MID

[Paul Christopher]

As already discussed on the mailing list (see ​http://dojo-toolkit.33424.n3.nabble.com/dojox-app-How-to-separate-model-definition-into-a-file-tp3995281.html), it would be nice if models could be loaded/instantiated by providing a MID. So you can write in the appconfig.json file:

...
"views": {
    "home": {
        "dependencies": [...],
        "template": "./home/view.html",
        "controller": "./home/controller.js",
        "model": {
            "names": {
                 "modelLoader": "dojox/app/utils/mvcModel",
                 "type": "dojox/mvc/ModelRefController",
                 "params":{
                     "mid": "./home/model.js"
                 }
            }
        }
    },
...

Whereas ./home/model.js is an AMD module that returns a class or a singleton:

define([
	"dojo/_base/declare",
	"dojo/Stateful"
], function(declare, Stateful){

             // Return a class. Could also return a singleton?
             return declare(Stateful, {
                  myprop1: 5,
                  myprops2: ...

                  _setMyProps3Attr: function (value) {
                      // A custom setter
                      ....
                      this._set('myProps3', value);
                  },

                  constructor: function(){
                      this.myprops3 = [1, 2, 3, 4];		
                  }
             });
});

Thanks for the patch, but it is too late to add new function to 1.9, so this will have to wait. The good news is that you can easily add your own custom model to your app to do this without having to wait for the update in dojox/app.
