Ruby on Rails Splitting or Slicing list into columns -
@locations = location.all #current listing @locations = location.slice(5) or location.split(5)
with ruby i'm trying split list 4 columns, limiting each column 5 each; neither slicing or splitting seems work. idea of might doing wrong? appreciated.
you want use in_groups_of:

here's ryan bates' example usage railscast:
<table> <% @tasks.in_groups_of(4, false) |row_tasks| %> <tr> <% task in row_tasks %> <td><%= task.name %></td> <% end %> </tr> <% end %> </table>
