ruby-on-rails-3.2

问题 Currently, I have a Rails 3.2.9 Engine which is using sass-rails . When I generate a controller with a couple actions, the assets are also generated (i.e., javascript and CSS). However, both the Javascript and SASS are *.js and *.css files. They're not CoffeeScript ( *.js.coffee ) or SASS ( *.css.sass ).
