What is the best way to modify this so that it only displays select
columns?
Coming from perl it seems natural to use a regex on the end like "if
column.name =~/column1|column2/". But is there a cleaner way in ruby?
<% for column in Affiliate.content_columns %>
<td><%=h affiliate.send(column.name) %></td>
<% end %>
i cant see exactly how you want this to be cleaner, you can go through the column list in your controller and decide which fields you want to display, then put these in a list.
