| There are 2 main problems with the code below: | |
| 1) It appears that fetch is getting called twice somehow | |
| 2) The fetched JSON is not parsing into the OfferClass objects. | |
| I have a server that returns the following JSON at /offerClasses | |
| [ {"id":1,"name":"Introductory"}, {"id":2,"name":"Loyalty"} ] | |
| Coffee file | |
| =========== | |
| window.app = | |
| models: {} | |
| views: {} | |
| class app.models.OfferClass extends Backbone.Model | |
| class app.models.OfferClasses extends Backbone.Collection | |
| model: app.models.OfferClass | |
| url: "/offerClasses" | |
| class app.views.OfferClassesView extends Backbone.View | |
| initialize: -> | |
| @model.bind "reset", @render | |
| render: => | |
| @model.each @addToDropDown | |
| @ | |
| addToDropDown: (offerClass) => | |
| $(@el).append($("<option></option>"). | |
| attr("value",offerClass.get("id")). | |
| text(offerClass.get("name"))) | |
| head.ready -> | |
| model = new app.models.OfferClasses() | |
| view = new app.views.OfferClassesView model: model, el: $('#offer-class-list') | |
| model.fetch() | |
| HTML file | |
| ========= | |
| <html> | |
| <head> | |
| <title>Offer Entry</title> | |
| <script type="text/javascript" language="JavaScript" | |
| src="http://cdnjs.cloudflare.com/ajax/libs/headjs/0.96/head.min.js"> | |
| </script> | |
| </head> | |
| <body> | |
| <div id="offer-type-section"> | |
| Offer Class: <select id="offer-class-list" /> | |
| </div> | |
| </body> | |
| <script> | |
| head.js( | |
| "http://cdnjs.cloudflare.com/ajax/libs/jquery/1.7/jquery.min.js", | |
| "http://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.2.2/underscore-min.js", | |
| "http://cdnjs.cloudflare.com/ajax/libs/json2/20110223/json2.js", | |
| "http://cdnjs.cloudflare.com/ajax/libs/backbone.js/0.5.3/backbone-min.js", | |
| "../lib/all_code.js" | |
| ); | |
| </script> | |
| </html> |
Updated with working code! Thanks Brian.

I forked the CS and hacked it a bit. I haven't tested it, I made it more idiomatic: https://gist.github.com/1472549
