からアップグレードしようとしていますRuby 1.9.3 to Ruby 2.1.2 (Rails 4.0)。RVMを使用しています。

Ruby 2.1.2 をインストールし、指定を含めて Gemfile を更新し、"gem 'paper_trail', '~> 3.0.5'"RVM で Ruby 2.1.2 に切り替え、新しい gemset を作成し、それに切り替えました。

次に、バンドルのインストールを行いました。

Rails サーバーを実行しようとすると、次のエラーが表示されます。

実行しようとしました: bundle exec rails generate paper_trail:install

移行ファイルが既に存在することを示していました (PaperTrail は 1.9.3 で動作していました)。それで、もう一度実行しました: bundle exec rails generate paper_trail:install -s

正常に完了しましたが、同じ問題があります。

config/initializers/paper_trail.rb:

# the following line is required for PaperTrail >= 3.0.3 with Rails
PaperTrail::Rails::Engine.eager_load!

module PaperTrail
  class Version < ActiveRecord::Base
    attr_accessible :captain
  end
end `

アイデア？役立つその他の情報はありますか？

編集: 初期化ファイル内の paper_trail 3.0.3 への参照にもかかわらず、gem はバージョン 3.0.5 です (gem リストを実行して確認)。エラー トレース内の 3.0.3 への参照は、Rspec 用です。

私はイニシャライザでやった：

module PaperTrail  
  module Rails  
    class Engine < ::Rails::Engine 
      paths['app/models'] << 'lib/paper_trail/frameworks/active_record/models'  
    end 
  end 
end

そして、これを置くことをお勧めします：

PaperTrail::Rails::Engine.eager_load!`

初期化子の最後の文字列として。
