私はレール初心者です。

移行を書いたばかりですが、実行しようとするrake db:migrate --traceとこのエラーが発生します。

(in /home/dkerschner/hsp-agent)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment

私はどこから来るdeviseを使用しようとしていますt.authenticatable20100129183653_change_agent_staff.rb

class ChangeAgentStaff < ActiveRecord::Migration
  def self.up
    change_table :agent_staff do |t|
      t.authenticatable
      t.timestamps
    end
  end

  def self.down

  end
end

これは私を夢中にさせています！私は何を間違っていますか？

以前にこれを再作成しようとしましたが、移行では問題ありません。問題は他の場所にあり、アプリを別の場所でエラーにすることができるかどうかを確認することをお勧めします。スクリプト/サーバーを起動して、それらのページを表示できるかどうか、またはエラーが生成されるかどうかを確認します。

アプリケーションはどのくらい進んでいますか？それがかなり新しい場合（そして、有効なRails 2.3.5がインストールされていることがわかっている場合）、最初から始めてみることをお勧めします。deviseを使用して認証を設定し、コマンドを文書化します。次に、失敗するまでに入力したすべてのコマンドとコードを投稿すると、問題をより適切に診断できるようになります。

複製しようとしたので、これを設定する方法が多すぎたため、これを求めています-デバイスジェネレータを使用するか、手動で、最初からデバイスを使用するか、ユーザーモデルがすでに作成された後にそれを追加するか作成した。

編集：現時点では、change_tableにdeviseのt.authenticableはありません。参照する列を手動で追加する必要があります。
