Would you duplicate the validation's regex, or reference a constant?
View option_1.rb
class User
field :username, :type => String
validates :username, :format => { :with => /\A[[:print:] ]{3,20}\Z/ }
end
class ScoreCard
belongs_to :user
field :username, :type => String
You can’t perform that action at this time.
