Rails 5: Ошибка создания образа Generatere Paperclip Migration Project

/ 13 октября 2018

Я получаю сообщение об ошибке при попытке создать миграцию с помощью скрепки.Я использую версию 5.1.0, она работала раньше, но теперь я получаю эту ошибку в командной строке.Я не уверен, в чем причина.

Я также использую active_admin, возможно, есть конфликт?

Сообщение об ошибке сообщает вам, в чем именно заключается проблема.

legnth не является допустимой опцией проверки рельсов.простая опечатка.

изменить на: 

 validates :title, presence: true, length: { maximum: 50 }
...
