Question

RORアプリケーション内のオブジェクトを破棄しようとしています。

しかし、私は次のエラーを取得する：

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "mailboxer_conversation_opt_outs" does not exist

私はこれは私が私のアプリの中にはありません。このmailboxer_conversation_opt_outsテーブルに関連している推測しています。

私はRailsの4.2を使用しています：

mailboxer (0.13.0) 
    carrierwave (>= 0.5.8) 
    foreigner (>= 0.9.1) 
    rails (>= 3.2.0) 

は私が何とか逃し移行ファイルはありますか？

とにかく、実際のオブジェクトがメッセージを送信できないうちに、どのように私のオブジェクトがこのテーブルに接続されますか？

ありがとうございます。

Answer 1

以前のバージョンのメールボックスを使用しているようです。

は新しいものに移行しよう：

ドキュメントから撮影

$ rails generate mailboxer:namespacing_compatibility 
$ rails generate mailboxer:install -s 
$ rake db:migrate 

：https://github.com/mailboxer/mailboxer#upgrading

Answer 2

Is there a migration file I somehow missed?

はい、itsnikolay's answerおよびドキュメントのUpgradingセクションを参照してください。

Anyway, how come my object is connected to this table while the actual object cannot send messages?

モデルクラスはおそらくまだあなたのActiveRecordクラス、お使いのモデルのdeclares several extra associationsにMailboxer::Models::Messageableモジュールが含まれてacts_as_messageableメソッドを呼び出しています。 Mailboxerのアップグレードを気にせず、モデルをMailboxerから完全に切断したい場合は、acts_as_messageable行を削除するだけで、関連付けに失敗した場合でもレコードを破棄することができます。
