#full_messages ⇒ Object

Redefine the ActiveModel::Errors::full_messages method: Returns all the full error messages in an array. 'Base' messages are handled as usual. Non-base messages are prefixed with the attribute name as usual UNLESS (1) they begin with '^' in which case the attribute name is omitted. E.g. validates_acceptance_of :accepted_terms, :message => '^Please accept the terms of service' (2) the message is a proc, in which case the proc is invoked on the model object. E.g. validates_presence_of :assessment_answer_option_id, :message => Proc.new { |aa| "#ActiveModel::Errors.aaaa.label (#ActiveModel::Errors.aaaa.group_label) is required" } which gives an error message like: Rate (Accuracy) is required
