Loading Backbone.Relational using Use! plugin

问题:

Backbone Relational is not an AMD compliant library, so I've gone ahead and found the use plugin to ensure underscore and backbone are both loaded as dependencies. Here is my config file

require.config({
  baseUrl: '../global/js',
  paths: {
    use: 'libs/utilities/use',
    jquery: 'libs/jquery/jquery-min',
    underscore: 'libs/underscore/underscore-min',
    backbone: 'libs/backbone/backbone-optamd3-min',
    text: 'libs/require/text',
    relational: 'libs/backbone/backbone-relational'
  },
  use:  {
    "relational": {
        deps: ["backbone","underscore"]
    }
  }
 });

I've also gone ahead and augmented the Backbone Relational library

(function(Backbone, _) {
  "use strict";

  Backbone.Relational = {
        showWarnings: true
  };

})(this.Backbone, this._);

Finally, I am calling relational within a model

 define([

    'jquery',
    'underscore',
    'backbone',
    'mediator',
    'relational'

    ], function($, _, Backbone, Mediator){

I am getting an error of cannot set property Relational of undefined. Meaning Backbone is not available. What am I missing?

回答1:

Backbone and underscore are not AMD compatible.

Upgrade warning: versions 1.3.0 and higher remove AMD (RequireJS) support.

To use (sic) the use plugin you do not need the AMD versions of underscore/backbone. You do need to wrap them though accordingly, i.e. in your require config have:

    use: {
        backbone: {
            deps: ["use!underscore", "jquery"],
            attach: "Backbone"
        },

        underscore: {
            attach: "_"
        },

        relational: {
            deps: ["use!underscore", "use!backbone"]
        }
        ....
    }
