Thanks Nathan! i forgot about == operator! (i'm fucking noob, 2hours
ago i didn't know about haml :D)
For second example we can use both == and | operators and get a
reasonable way of doing that with haml.
- content_for :onload_scripts do
== $('#search_items').autocomplete(' |
#{url_for(:controller => '/items', :action =>
'search').to_json}, { |
selectFirst: false, |
minChars: 2
});
Though your way is also nice, thanks again!
