Rails 3.1. How to prevent Rails to use CoffeScript?

Question

How do I prevent Rails to enable CoffeeScript and use plain JavaScript instead?

Answer 1

Comment out gem 'coffee-script' in Gemfile

Answer 2

Just name your files .js instead of .js.coffee. This is a Tilt naming convention. Similarly, if you don't want to use SCSS, use .css instead of .css.scss. Or if you'd rather use the Sass syntax with semantic whitespace, use .css.sass.

By default, .js.coffee files are created by certain commands (notably generate controller) as long as gem 'coffee-script' is in the Gemfile, so you'll want to comment that out.

Answer 3

Comment out # gem "coffee-script" in your gemfile or just use .js vs .js.coffee files
