⚖️ Numericality Validation​

Validate that an attribute is a number, optionally restricting it to integers or range limits. This is useful for age, price, or quantity fields. Configure options like only_integer, greater_than, or less_than_or_equal_to.

class Product < ApplicationRecord
  validates :price, numericality: { only_integer: true, greater_than: 0 }
