Backbone: Create collection from JSON

rated 0 times [ 56] [ 6] / answers: 1 / hits: 29213 / 13 Years ago, mon, january 16, 2012, 12:00:00

I'm attempting to load JSON (from php's json_encode) into a Backbone JS collection. I've simplified the problem to:

var myJSON = '[{ id:1,name:some name,description:hmmm}]';



var myCollection = new MyCollection(myJSON, { view: this });

And:

MyObject = Backbone.Model.extend({



  id: null,

  name: null,

  description: null

});



MyCollection = Backbone.Collection.extend({ 

model: MyObject,

initialize: function (models,options) { }

});

Error:

Uncaught TypeError: Cannot use 'in' operator to search for 'id' in

My JSON certainly appears to be in the right format, am I missing something obvious? I have attempted using simply id: 1 as opposed to id with the same result.

Your JSON is still in string format. Pass it to JSON.parse before assigning it:

var myJSON = JSON.parse('[{id:1,name:some name,description:hmmm}]');
