レールが私の掃除機を見つけることができないのはなぜですか？

Question

私は私のコントローラで持っている：

class FormulariosController < ApplicationController 
    cache_sweeper :campanha_sweeper, :only => [:show] 

    # actions 
end 

私は/掃除アプリの内側と、それは動作しませんでしたというディレクトリを作成しようとしました、私はそこにあった（/キャッシュフォルダを作成するために、モデルの内側に試してみました例としてこれを使ったブログ）、それはうまくいかなかった。

マイスイーパーは、次のようになります。

class CampanhaSweeper < ActionController::Caching::Sweeper 
    observe Campanha 

    def after_update(campanha) 
    expire_cache_for(campanha) 
    end 

    private 
    def expire_cache_for(campanha) 
    expire_page(:controller => 'formularios', :action => 'show') 

    ap "Expired cache for formularios#show in formulariosweeper" 
    end

なぜそれが動作しませんでしたか？また、（レンダリング方法の）ビューのみのキャッシュを期限切れにする方法はありますか。私はその場でビューを生成しています。ビュー/ formularios/a.html.rbにあるビューのキャッシュを期限切れにすることができれば非常に便利です。

私は、それは簡単です。私はフォームを使ってビューを生成し、そのビュー（またはそのコード）を更新したいときにプロダクションになると、ビューがキャッシュのために更新されないため、フォームを更新するたびに手動でキャッシュをリセットする必要があります。

ありがとうございました。

ディレクトリ（またはこれまでにスイーパコードを入力した場所）をautoload_pathsに追加しましたか？application.rb？
