In the RoR book by Dave following code is there in list.rhtml
<% for column in Product.content_columns %>
<td><%=h product.send(column.name) %></td>
<% end %>
Where is this method named ''send'' defined. I also looked at
the
documentation for ActiveRecord::Base but couldn''t find any info
regarding ''send''.
Thanks.
