Rails - Aug 2006 - Getting an array of ids from form checkboxes?

Is it possible to set up a list of checkboxes so that the form  
parameters are given in an array  (eg  {"delete_list" => [3,6,7]})
?

At the moment I''m using
<%= check_box_tag "delete_list[#{post.id}]" %>

...which gives parameters looking like {"delete_list" =>
{"3" => "1",
"6" => "1", "7" => 1}}, which seems
unnecessarily ugly...

Any suggestions?

Try this (tweaked as needed):

   <% @posts.each do |post| %>
     <%= check_box_tag "delete_list[]", post.id %>
   <% end %>

You should end up with params[:delete_list] being an array of the
boxes you''ve checked.
