I have an app which uses ActiveResource to get data from a non-Rails  
client. One of the things it has to do is display that data in a  
webpage, with subtotals by week. What’s an easy way to break up a  
collection of ARes instances by a column so I can then pump each group  
into a partial. The partial then displays the lines for that group, and  
a sub-total at the end.

The other way I could do it is to xml-ise the ARes records, generate the  
table, with groups and subtotals using XSLT, and then feed that as text  
into a render method. But that involves stepping outside Rails to format  
stuff.

Anyone have any ideas?

Thanks
