使用結束作爲列名

Question

我堅持認爲沒有列名一些不幸的選擇，一軌2.1應用程序。例如，一個事件有一個開始和結束日期。而不是使用start_at和end_at原設計採用start和end。當然這導致

def end 
    read_attribute(:end) || 1.hour.from_now 
    end 

我很驚訝這甚至解析。這是合法的紅寶石？真正的問題是，當運行一個backgroundrb作業來發送提醒郵件時，erb正在'堆棧層面太深'爆炸。模板是

<%= [@event.name, @event.when_pretty, @event.location, @event.association, 
@event.notes].reject(&:blank?) * "\n" %> 

如果我在控制檯deliver_reminder沒有錯誤，但是當deliver_reminder後臺作業過程中被調用時，出現錯誤。

問：我應該重構刪除end方法，或在堆棧錯誤是由別的原因引起的？

Answer 1

原來的問題是一個名爲association庫方法，當我改變了調用associated_object（這是所謂的由協會＃協會），堆棧錯誤不再發生。
