Uncaught TypeError: undefined is not a function rails3/backbone/js

Question

I just started delving into javascript to make project more responsive and I am working through a backbone.js example.

Answer 1

Ran into the same problem, and then I figured out that I haven't included underscore.js anywhere. So I wrote a simple backbone.js file:

/*
 *= require backbone/underscore-min.js
 *= require backbone/backbone-min.js
 */

and stored it under vendor/assets/javascripts along with the Backbone and Underscore files:

vendor/assets/javascripts/
├── backbone
│   ├── backbone-min.js
│   └── underscore-min.js
└── backbone.js

---

My application.js.coffee looks something like this one now:

#= require backbone
#= require query
