It is telling you the line that the problem is (line 27 in
user_controller.rb, which is a bit odd, I would have expected it to be
called users_controller.rb not user_controller.rb), and the error
tells you that you are calling gsub, but the object you are calling it
on is a number instead of a valid object that understands the method
gsub. Have a look at that line. Then if you cannot see the problem
have a look at the Rails Guide on debugging for suggestions on how to
debug your code.
