When navigating to: http://localhost:3000/users/12
Whats a good way of avoiding the error: "Couldn't find User with
ID=12", which happens when i try to display a page of user_id 12 that
doesnt exist in the database.
Instead of showing the error. id like to show a page that says: "This
user does not exist"
Someone suggested using rescue_from. Is this the best solution for
this? Or are there better alternative approaches?
