Hi,
I have multiple checkboxes in a table each one representing an item.
They are like this:[...]
<td><%= check_box "incidencias_ids", incidencia.id %></td>
<td><%=h incidencia.cliente.nombre %></td>
[...]
Try check_box_tag "incidencias_ids[]", incidencia.id
There's more about why this works (ie what the [] are about) in the
guide on form helpers at guides.rubyonrails.org.
