link_to "eat chocolate", :controller => 'user', :action=>'eat_chocolate', :id=> user

add the following line to your routes.rb file.

match 'user/eat_chocolate/:id' => 'user#eat_chocolate', :as => :eat_chocolate_user

Look up named routes for more info.

In some cases it will be better to use GET.

Using match will accept ALL http verbs GET PUT POST DELETE meaning that somebody could potentially mis-use your application. If all you're doing is showing something in a #show action, you should use this instead

get 'user/eat_chocolate/:id' => 'user#eat_chocolate', :as => :eat_chocolate_user
