ActiveRecord

Translations on ActiveRecord models (on class-level)

    class Post < ActiveRecord::Base
      validates_presence_of :country_id, :message => _('Select one fool!')
    end

Someting like this did never work with GetText and can never work since at the point the class is loaded neither text_domain nor locale should be set
(no user has logged in yet). The only reason it will blow up now when using FastGettext
is that FastGettext will complain when no `text_domain/locale` is set whereas GetText gave no feedback and merrily returned the msgid.

GetText means fast_gettext or ruby-gettext? *ruby-gettext and gettext_rails work using N_() *

    class Post < ActiveRecord::Base
      validates_presence_of :country_id, :message => N_('Select one fool!')
    end

There are 2 possible solutions I found:

1. use validate do and add the message dynamic
2. use Rails I18n framework, by adding

    activerecord:
      errors:
        models:
          post:
            presence: "Select one fool!"

to all config/locales/xxx.yml and remove the :message=>xxx part.
(my preferred solution since it is very simple and reduces logic)

---

Third possible solution would be to enable procs as custom messages:

    validates_length_of :archives, :minimum => 1,
      :message => proc {_('Gadget requires at least one archive ')}

Get my monkey patch to enable this!
