Object.destroy генерирует ArgumentError: неправильное количество аргументов (1 вместо 0)

У меня есть простая модель, где

class User < ActiveRecord::Base
  has_many :comments, dependent: :destroy
  has_many :answers, dependent: :destroy
end

Когда я пытаюсь удалить с помощью User.first.destroy (на консоли), я получаю: ArgumentError: неправильное количество аргументов (1 вместо 0).

Детали:

u.destroy
Comment Load (0.2ms)  SELECT "comments".* FROM "comments" WHERE "comments"."user_id" = 4
SQL (14.6ms)  DELETE FROM "comments" WHERE "comments"."id" = ?  [["id", 4]]
SQL (0.1ms)  DELETE FROM "comments" WHERE "comments"."id" = ?  [["id", 5]]
SQL (0.0ms)  DELETE FROM "comments" WHERE "comments"."id" = ?  [["id", 6]]
ArgumentError: wrong number of arguments (1 for 0)

Камень bullet кажется проблемой. Посмотрите на первую строку вашей трассировки стека. Проблема заключается в этом методе. Вероятно, это вызов origin_has_cached_counter?, на который он жалуется.

Спасибо! Я не помнил, что пуля была установлена ​​мной ... и я думал, что это ошибка ядра рельсов. - person matreyes; 22.03.2012

Вы забыли => в своей модели и поставили :, которого там не должно быть ;) Должно быть так:

class User < ActiveRecord::Base
  has_many :comments, :dependent => :destroy
  has_many :answers, :dependent => :destroy
end

нет, все в порядке. В ruby ​​1.9 dependent: такой же, как :dependent => Проблема была в пуле гема, теперь все работает. Спасибо. - person matreyes; 22.03.2012
