The ?instit_id=3 is there because in the link you have specified
:instit_id => instit.id thereby requesting instit_id to be included as
a parameter

The fact that it is complaining about a missing template suggests that
it has successfully gone to the shownames action and is trying to

for the view file. Can you supply the full path and filenames for the
controller and view files please?
