How to write coffeescript inside html.haml/html.erb?

Question

Ruby on Rails

I can do this:
app/views/some_controller/some_action.html.haml

%h1 Заголовок
javascript:
     alert("Это js #{@some_var}");

And I want, but I can't:
app/views/some_controller/some_action.html.haml

%h1 Заголовок
coffescript:
     alert "Это кофе #{@some_var}"

Answer 1

Isn't there a colon in front of haml(:coffeescript)?
