Even better, just don't use uri_for if you don't have to. Relative uris
are your friend. They still work. The web still functions without
uri_for. :-)

If you are working on an index page, and you have create/edit/view links
that are relative to that page, just use html:

##default
[% FOREACH item in items %]
   <a href=3D"[% item.id %]">...</a>
[% END %]
