should be called "signatures" (plural) or "signature" (singular). Also, note that when accessing values in the params
hash, we usually use symbols, not strings, so [:index]
instead of ["index"]
. This should put you on the right track.

put "/signatures/:index" do update_signature(params[:index], params[:signature]) end
