I build a similar link, but send it in an email (to a support desk
person). I use this (adjusted for your context)
A(" (GET BROCHURE)", _href="http://oursupport.com"; + URL("download", args=
row.brochure))
This sends a link to the download() controller from the sample default.py
(adjusted to do some logging), with the appropriate file as an argument.
