thanks for the tip! - here's what the eventual code looks like.
<repeat with="&fields.split(',')">
<td style="text-align:center; font-weight: bold;">
<%= "$#{total_price}" if this.gsub(/,/,'').strip ==
'total_price' %>
</td>
</repeat>
Notice the total_price, summed by the table. Rather than summing the
entire database, which wouldn't take in to account filters/pagination,
could take a long time, and would probably be better off in
controller...
<prepend-tr:>
<% logger.warn "This: #{this.inspect}"
total_price = total_price + this.total_price %>
<hidden-id-field/>
</prepend-tr:>
I suppose I should put the with fields thing on to the lighthouse..?
Cheers & Thanks,
--Peter
