Rails "неопределенная локальная переменная или метод" для attr, который даже не связан

2 голосов
/ 05 августа 2009

Я в растерянности здесь. При работе в режиме Dev (скрипт / сервер) я выдает ошибку «undefined local variable or method 'id' for #<InsertModelNameHere:0x7f19bdb87dc8>» в случайное время, когда пытаюсь составить список записей для ряда моих моделей. Если я обновляю страницу, она работает нормально, и я предполагаю, что вижу ее только в dev, потому что все перезагружается для каждого запроса. Может быть, состояние гонки или что-то происходит? Я даже не ссылаюсь на атрибут «id» (устаревшая таблица, которая использует другое соглашение об именах ключей) в представлениях, где это является проблемой. Один из моих коллег сообщил мне, что rails создаст атрибут «id» на основе хотя первичный ключ определен в модели.

Ниже приведен код для представления, сообщения об ошибке и трассировки стека. Я бегу по рельсам 2.3.3.

<h2 class="textCenter">To Do List</h2>

Вы установили primary_key на Todo? 

class Todo
  set_primary_key 'pk_todo_id'

end

Я думаю, что это может быть вашей проблемой. Дайте мне знать, что происходит.

Удачи!

Я собираюсь вернуться к 2.3.2, так как не могу правильно применить этот патч. Я собираюсь предположить, что это проблема, тем более что она специфична для 2.3.3. Спасибо всем за помощь.
