Refinery Admin extension solving Globalize + Crudify issues

admin_controller_decorator.rb

# Extension to Refinery Admin controller to avoid 2 problems:
#
# 1) Edit locale propagates through requests as Thread.current[:globalize_locale] is never reset to nil
# 2) Crudify's find filter is pepended before de globalize filter. This way, if you're editing in a non-default locale and the update url comes with a slug in that locale it won't be found (in fact, it does work in some circunstances)

::Refinery::AdminController.class_eval do

  # We should reset globalize so we don't propagate Globalize locale between requests
  def reset_globalize
    Thread.current[:globalize_locale] = nil
    I18n.locale = params['switch_locale'].to_sym unless params['switch_locale'].nil?
    globalize!
  end

  # We should prepend the globalize filter after crudify or else we would search for a slug before the locale is loaded
  def self.crudify *args
    super *args
    prepend_before_filter :reset_globalize
  end
