Did you mean to require id = params[:id]? That means it can only ever
find the one with that id, and then only if its time fields fit.
Also note that this method would be better as a scope method of the
Tee model, though that is not the cause of the error.

Have you checked that params[:id] actually contains a value? Have a
look in development.log to see what params are being passed in. Also
have a look at the Rails Guide on debugging and find out how to use
ruby-debug to break into your code and examine data and follow flow.
It is an invaluable technique when you cannot work out what is going
on.
