everything seems correct, but whenever I do the following, I get TypeError: f is undefined in backbone 1.1.2, Also, when I debug, I saw that it was able to receive the correct response, yet when I do categories.toJSON() I get nothing:
var categories = new App.Lookup.CategoryCollection();
categories.url = 'index.php?r=lookupapi/categories';
categories.fetch();
App.Lookup.CategoryCollection = Backbone.Collection.extend({
model: App.Lookup.CategoryModel
});
App.Lookup.CategoryModel = Backbone.Model.extend({
});
What am I doing wrong here?
Update:
I use the development version as suggested by user972 and got the following error message:
TypeError: this.model is undefined
categories.fetch() is the one causing the error, it pointed to this function in backbone:
// Define how to uniquely identify models in the collection.
modelId: function (attrs) {
return attrs[this.model.prototype.idAttribute || 'id'];
},
But I still couldn't figure out why it is undefined.
Just out of curiosity, have you referenced the script files in the proper order? It seems more of from script loading error than the code based.
<script src="underscore-1.6.0-min.js"></script>
<script src="backbone-1.1.2-min.js"></script>
Other thing that might be of help is to use non-min version of backbone and try locating where it is crashing and why?
<script src="http://backbonejs.org/backbone.js"></script>
