But 0 passes this regex -- it's one digit. If you wanted to ensure
that you had n or more digits, you would use a regex like this:
^\d{2,}$
to match two or more digits.
Or, you could check to see if the first digit was larger than a 0 if
that first digit cannot ever be 0:
^[1-9]\d*$
That will match 1, but not 0, and also 10, 11, 12 ...

This is one simple way to check this: puts "f123" to field.
"f123".to_i => 0
"123f".to_i => 123
But in Rails validation, "f123" is validates too.
