Question

Я начал получать следующую ошибку при работе.

Я пытался проверить, есть ли у кого-то проблема, и в некоторых сообщениях говорилось, что для "config.eager_load" установлено значение true.Однако этот способ уже задан в рабочей среде.

Проблема начинается, когда код пытается проверить, авторизован ли пользователь для чтения здания в строке «authorize!: Read, @building».

class DocumentableCountController < ::Frontend::ApplicationController
  before_action :redirect_if_no_building

  def index
    authorize! :read, @building

    ...
  end

  ...

Вызывает следующий метод изнутри, где возникает ошибка, которая находится в строке "@current_ability || = Ability.new (заинтересованных лиц)".

module Frontend
  class ApplicationController < ::ApplicationController
    ...
    def current_ability
      stakeholder = current_admin || current_user

      @current_ability ||= Ability.new(stakeholder)
    end
  end
end

Выдает ошибку:

RuntimeError: Circular dependency detected while autoloading constant Ability

Ожидается, что этой ошибки не будет.

Дополнительная информация

Следующий код является классом ":: ApplicationController", унаследованным интерфейсом модуля выше..

class ApplicationController < ActionController::Base
  include HasFrontendPartner
  include RescuesNotFound

  protect_from_forgery with: :exception

  rescue_from CanCan::AccessDenied do |exception|
    respond_to do |format|
      format.html { redirect_to "/403", notice: exception.message }
      format.json { render json: { error: exception.message }, status: 403 }
    end
  end
end
