Rails : how to change resourceful actions parameters

Question

For standard rails resourceful actions (say communications controller )

  index
  create
  show
  update

show has parameter id

get /communications/:id

route

Is it possible I can have

   get /communications/:username 

for show action?

Thanks for any help.
