Actually, here it is better to use [0-9] for number as \d allows plus
and minus signs as well as point.
The same for spaces it is better to use [ -] to allow only those
characters.
And not restricting the validation on create.

Here, on the contrary it is better to use \d. And if you use
before_validation_on_create, and before_validation_on_update, it
should work.
