Check only rooms

Question

In one of my rail models, I have this check :only_integer:

validates :number, presence: true, numericality: { only_integer: true }

This check also allows for inputs such as [phone]with +-signs.

Which check should be used only for input permissions without + -just numbers?

Answer 1

The documentation for only_integermentions this regular expression:

/\A[+-]?\d+\z/

This means that you can simply use:

validates :number, format: { with: /\A\d+\z/, message: "Integer only. No sign allowed." }
