Rails Admin - неопределенный метод `'для многократной загрузки Carrierwave

Я не могу редактировать некоторые записи в Rails Admin после нескольких загрузок файлов с помощью Carrierwave.

Я думаю, что все правильно, когда я загружаю файлы, все идет хорошо, но если я пытаюсь редактироватьпосле сохранения записи возникает ошибка:

Модель проекта: 

mount_uploaders :images, ProjectImageUploader

У меня была такая же проблема, и мне помогло добавление этих методов в модель: 

  attr_accessor :delete_images
  after_validation do
    uploaders = images.delete_if do |uploader|
      if Array(delete_images).include?(uploader.file.identifier)
        uploader.remove!
        true
      end
    end
    write_attribute(:images, uploaders.map { |uploader| uploader.file.identifier })
  end

  def images=(files)
    appended = files.map do |file|
      uploader = _mounter(:images).blank_uploader
      uploader.cache! file
      uploader
    end
    super(images + appended)
  end
...
