Well, I'm a newbie in rails and habtm worked just fine for my simple
application.
Jason you pointed me in the right direction and after a quick search I did
it.
My working code is the following (in case somebody needs it):
<%= check_box_tag "foo[bar_ids][][#{bar.id}]",
tag.id, @foo.bars.include?(bar) %>
<label for="foo_bar_ids__<%= bar.id %>"><%= bar.Name
%></label>
David, thank you for your answer too.
