default_scope for MySQL to PostgreSQL project migration. The id sort order is not == when compared to MySQL and many specs are failing, even some relating to Gem models.

sorted_by_id.rb

# Needed because I also have Gem models that are throwing errors not just my models. I'd like to have one simple mixin or monkey patch.
# without mucking with ActiveRecord::Base too much.

module SortedById
  extend ActiveSupport::Concern
  included do
    default_scope order('id ASC')
  end
end
ActiveRecord::Base.send(:include,SortedById)


# Oh Noes!!!
#ruby/1.9.1/gems/activerecord-3.2.11/lib/active_record/model_schema.rb:148:in `reset_table_name': undefined method `abstract_class?' for Object:Class (NoMethodError)
#from /Users/hankbeaver/blinqmedia/blinq_ad_manager/local/ruby/1.9.1/gems/activerecord-3.2.11/lib/active_record/model_schema.rb:104:in `table_name'

Maybe a cleaner solution:

class ActiveRecord::Base
  def self.default_scope
    order(:id)
  end
end

I tried a monkey patch as a well as creating my own base class that extends ActiveRecord::Base. The former, still threw the abstract_class? exception and the latter could not introspect the table name of the model anymore and asked for me to self.table_name = ?. Trying another route. Thanks!
