def success?
  valid? && errors.empty? # valid? ensures validations have run, errors.empty? catchs errors added during execution
end

#valid?(context = nil) ⇒ Boolean

Ensures all validations have run, then returns true if no errors were found, false otherwise. NOTE: Overriding ActiveModel::Validations#valid?, so as to not re-validate (unless reset! is called). SEE: www.rubydoc.info/gems/activemodel/ActiveModel/Validations#valid%3F-instance_method

Returns:

  • (Boolean)
