#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 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'

Переопределяет метод ActiveModel::Errors.full_messages. Сообщения об ошибках для атрибутов теперь не имеют префикса с названием атрибута если в сообщении об ошибке первым символом указан “^”.

Так, например,

validates_acceptance_of :accepted_terms, :message => 'нужно принять соглашение'

даст сообщение

Accepted terms нужно принять соглашение

однако,

validates_acceptance_of :accepted_terms, :message => '^Нужно принять соглашение'

даст сообщение

Нужно принять соглашение

Returns all the full error messages in an array.

class Company
  validates_presence_of :name, :address, :email
  validates_length_of :name, :in => 5..30
end

company = Company.create(:address => '123 First St.')
company.errors.full_messages # =>
  ["Name is too short (minimum is 5 characters)", "Name can't be blank", "Address can't be blank"]
