The error is saying you have no arguments to the {% url %} tag. Make sure
that req.id is actually resolving to an integer value.
Templates are fun when they mask missing values like that. You already have
it displayed earlier in the template. Comment out the {% url %} tag and see
if a number is displayed in your template.
