gemを使用して Postgres Hstore を追加しようとした Rails 3.2.11 アプリがありactiverecord-postgres-hstoreます。アプリは PG-9.1.9 db を使用した開発では動作しますが、PG-9.1.8 db を使用した運用サーバーでは次のエラーが発生します。uninitialized constant ActiveRecord::Coders::Hstore (NameError)

ログ ファイルは次のとおりです。

Rails 4 以降

Rails 4 を使用している場合はactiverecord-postgres-hstore、ActiveRecord 4 がHStore型サポートを提供するため、gem は必要ありません。

変化する

class Book < ActiveRecord::Base
  serialize :properties , ActiveRecord::Coders::Hstore
  serialize :bookmark_count , ActiveRecord::Coders::Hstore
end

に

class Book < ActiveRecord::Base
  # You don't need it anymore
  # serialize :properties , ActiveRecord::Coders::Hstore
  # serialize :bookmark_count , ActiveRecord::Coders::Hstore
end
