== DESCRIPTION:

Live validator is a Rails Guilded (http://github.com/midas/guilded/tree/master) component that will reflect ActiveRecord validations and use them to live validate forms. Live validator uses the Live Validation (http://www.livevalidation.com) JavaScript library to accomplish this task. It also uses an ActiveRecord extension authored by Michael Schuerig to mre easily reflect on the ActiveRecord valdiations.

== FEATURES:

• Validate Rails XHTML forms without submitting form to server.
• Declare validations once in ActiveRecord model's. If JavaScript is enabled, the validation will happen live. Otherwise, the validation will happen normally, with a submission to the server.
• The error message defined in the validation macro will be used in live validation
• The following ActiveRecrod validations are currently implemented and working: validates_presence_of (:message), validates_numericality_of (:less_than, :less_than_or_equal_to, :equal_to, :greater_than, :greater_then_or_equal_to, :only_integer, :notANumberMessage, :notAnIntegerMessage, :wrongNumberMessage, :tooLowMessage, :tooHighMessage), validates_length_of / validates_size_of (:maximum, :minimum, :is, :within, :in, :too_long, :too_short, :wrong_length), validates_confirmation_of (Only works for 2 fields, no more nor less.), validates_acceptance_of (:message), validates_inclusion_of (:message), validates_exclusion_of (:message)
