Given a model: class Person validates_lenght_of :name, :maximum => 50 end I have some view code that shows a countdown and enforces this maximum. However I hard coded the number 50 into that view code. Is there a way to extract this number from the model? Something like: Person.maximum_length_of_name I tried this: Person.validators_on(:name) => [#<ActiveRecord::Validations::UniquenessValidator:0x000001067a9840 @attributes=[:name], @options={:case_sensitive=>true}, @klass=Trigger(id: integer, name: string, created_at: datetime, updated_at: datetime, user_id: integer, slug: string, last_update_by: integer)>, #<ActiveModel::Validations::PresenceValidator:0x000001067a6c30 @attributes=[:name], @options={}>, #<ActiveModel::Validations::LengthValidator:0x000001067a3f08 @attributes=[:name], @options={:tokenizer=>#<Proc:0x00000101343f08@/Users/sjors/.rvm/gems/ruby-1.9.2-p0/gems/activemodel-3.0.6/lib/active_model/validations/length.rb:9 (lambda)>, :maximum=>50}>] The information is in there, but I don't know how to extract it:
