Gon gem — get your Rails variables in your js

If you need to send some data to your js files and you don't want to do this with long way trough views and parsing - use this force!

Usage

app/views/layouts/application.html.erb

<head>
  <title>some title</title>
  <%= gon_variables %>
  <%= javascript_include_tag 'http://code.jquery.com/jquery-1.6.min.js' %> <!-- include jquery -->
  <%= include_gon_js %> <!-- http://gaziev.com/files/gon.js -->
  ...

In action of your controller you put something like this:

@your_variable = 123
Gon.your_variable = @your_variable
Gon.your_other_variable = 345 + @your_variable

In javascript file for view of this action write call to your variable:

alert(Gon.your_variable)
alert(Gon.your_other_variable)

Installation

Puts this line into Gemfile then run $ bundle:

gem 'gon', '0.1.0'

Or if you are old-school Rails 2 developer put this into config/environment.rb and run $ rake gems:install:

config.gem 'gon', :version => '0.1.0'

Or manually install gon gem: $ gem install gon
