Why not just hard-code %url_params? Often it will be a lot more obvious to
see what you're actually passing on.
$url_params{foo} = $db_row->{whatever};
I used to think making everything very dynamic was a good idea. I don't
anymore. There's a bunch of cases where being specific can make the code
easier to read and less exposed to bugs.
