#full_messages ⇒ Object

Redefine the ActiveRecord::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| "#{aa.label} (#{aa.group_label}) is required" }
which gives an error message like:
Rate (Accuracy) is required
