rjv is a set of helpers that can inject any variables from rails to your javascript code.

Add this code at the bottom of your layout file (before closing body tag).

== rjv_tags

Now you can inject variables in your views:

- set_var 'someVar', 'someValue'

In javascript this variable will be available as:

console.log(app.vars.someVar)
