Try:
= link_to_unless_current('Contact', contact_index_path) do
- link_to 'Contact', contact_index_path, :class => 'active'
Note the '-' instead of '=' in the second line. It means that that
line should be executed, but the result shouldn't be appended to the
page. This is equivalent to the ERB you included above and the first
(single line) haml version.
