# If you want to make the regex dry/not repeat for every model. Create a module in your lib folder say:
module RegexValidations
  def self.alphanumeric_underscore
    { with: /\A[\w\_]+\z/ }
  end
end


# And in your model include it and say:
include RegexValidations
validates :description, presence: true, format: RegexValidations.alphanumeric_underscore
