Rails アプリケーションを 3.2.13 から 4.0.0 にアップグレードした後、移行コマンドが失敗し、「バージョンは Active Record によって定義されています」と表示されます。
MySQLデータベースを見てみると、schema_migrationsテーブルと"version"という名前のカラムがあり、ActiveRecordメソッドと競合しているようです。
誰かがこの問題を解決する考えを持っていますか?
私のGemfileの一部
- アクションメーラー (4.0.0)
- アクションパック (4.0.0)
- actionpack-action_caching (1.0.0)
- actionpack-page_caching (1.0.0)
- アクティブモデル (4.0.0)
- アクティブレコード (4.0.0)
- activerecord-deprecated_finders (1.0.3)
- アクティブサポート (4.0.0)
- mysql2 (0.3.13)
エラー
テーブルを持たないクリーンなデータベースでテストしましたが、増分移行も失敗します。
コマンドを実行すると、テーブル schema_migrations が生成され、列 "version" がレコードなしで表示されますが、:users テーブルが作成されます。したがって、schema_migrations.version は :users の移行バージョンを適切に設定しています。
