Object.destroy генерирует ArgumentError: неверное количество аргументов (1 для 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 файл User.first.destroy (на консоли), я получаю: ArgumentError: неверное количество аргументов (1 для 0).

Подробности: 

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)

Кажется, проблема в bullet драгоценном камне. Посмотрите на первую строку вашей трассировки стека. Проблема внутри этот метод . Это, вероятно, origin_has_cached_counter? звонок, на который он жалуется.

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

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