Rails應用程序：允許用戶在未登錄的情況下進行購買

Question

我試圖刪除我的Rails應用程序中的註冊/登錄要求，以便用戶進行預訂，但未能這樣做。我很新，我不確定我想做什麼其他更改，但錯過了，任何幫助將不勝感激，謝謝！

工作代碼（與註冊/登錄的要求）

class CourseController < ApplicationController 
     before_filter { @account_menu = :courses } 
     before_filter :authenticate_user!, :except => ['show', 'find', 'messages', 'chat_threads', 'new'] 

     before_filter lambda { 
     if current_profile.try(:learner?) 
      flash[:alert] = "You cannot access these pages" 
      redirect_to '/' 
     end 
     }, :only => [:new, :edit, :cancel, :start, :complete] 

     before_filter lambda { 
     if current_profile.teacher? 
      flash[:alert] = "You cannot access these pages" 
      redirect_to '/' 
     end

我試圖刪除要求註冊/登錄如下所示。我沒有做到這一點，因爲點擊書籍按鈕將我帶回主頁而不是書籍視圖。

    before_filter { @account_menu = :courses } 
    before_filter :authenticate_user!, :except => ['show', 'find', 'messages', 'chat_threads', 'new', 'book']

    if current_profile.try(:learner?) 
     flash[:alert] = "You cannot access these pages" 
     redirect_to '/' 
    end 
    }, :only => [:new, :edit, :cancel, :start, :complete] 

    before_filter lambda { 
    if current_profile.try(:teacher?) 
     flash[:alert] = "You cannot access these pages" 
     redirect_to '/'

    }, :only => [:book, :wish_list, :wish, :unwish, :cancel_booking, :pending]

對不起，如果需要更多的信息，我會很樂意重新裝修。

處理此問題的標準方式是爲創建該用戶的用戶帳戶，沒有任何個人詳細信息，但保留它們「登錄」到此用戶帳戶。通過這種方式，他們可以在頁面上持久化，可以填滿他們的籃子，稍後再回到同一臺計算機等。

後來，當您真正需要他們的個人詳細信息時，可以說「在我們進入下一步之前，您需要寄存器」。然後，您可以將個人詳細信息添加到您之前爲其創建的帳戶中，然後執行電子郵件驗證或任何您想要執行的操作。

通過這種方法，您最終會得到大量「不完整」的用戶帳戶，而這些用戶從不打算註冊，而且您可以安排一個計劃任務來刪除所有超過一週的用戶帳戶例。
