💡 Hint

Common Mistakes

Using edit or new which are for different actions.

Using index which lists all users.

The user_show_path is not a standard Rails helper. The correct helper is user_path(5) for showing a user. But since the blank is inside the helper name, the correct part is show to complete user_show_path.
