Require Formtastic styles in Rails 3.1

Formtastic help says to add next lines in application.css:

# app/assets/stylesheets/application.css
*= require formtastic
*= 开发者_如何学JAVArequire my_formtastic_changes

But what i'm gonna do when it is scss? Can't find it in search engines.

theres nothing left to do for you, place your my_formtastic_changes.scss in app/assets/stylesheets. Rails will automagically compile your scss file and add it to application.css
