Add default_scope to sort by :id for MySQL -> PostgreSQL migration, working version Rails 3.1.x

sorted_by_id.rb

# Add to initializer

module SortedById
  extend ActiveSupport::Concern
  included do
    default_scope order('id ASC')
  end
end
Rails.application.eager_load!
models = ActiveRecord::Base.subclasses.collect {|ea| ea.name}
models.each do |mod|
  Module.class_eval(mod).send(:include,SortedById)
end

Was there a reason you didn't declare the default_scope on ActiveRecord::Base ?

   ActiveRecord::Base.class_eval do
      default_scope order('id ASC')
   end
