Given your data, looks like you don't need to customize the collection. Just add the view tag below it. On a side note, you might want to take look through the dryml guide at some point as copying the whole show-page def isn't the dryest way to proceed. http://cookbook.hobocentral.net/manual/dryml-guide You can extend the tag instead and just replace/add the bits you need to change. By the way, this is not a requirement, just a suggestion that will make dryml pleasanter to work with in the long run. As an example, if adding the sum is the only change to make you could do: <extend tag="show-page" for="Proyecto"> <old-show-page merge> <after-collection:> Total: <view field="plan_operativos.sum(:cant)" /> </after-collection:> </old-show-page> </extend> Or even add app/views/proyectos/show.dryml if this is your only show-page for proyecto: <show-page> <after-collection:> Total: <view field="plan_operativos.sum(:cant)" /> </after-collection:> </show-page> -- You received this message because you are subscribed to the Google Groups "Hobo Users" group.
