使用 SentientUser 配置 Cucumber

Question

我有一个使用 SentientUser gem 向我的模型提供当前用户的应用程序。最重要的是，我使用默认范围来确保用户只能访问他们拥有的数据。所以对我来说，一个典型的模型看起来像这样：

class Location < ActiveRecord::Base
  validates_presence_of :name, :time_zone, :address

  belongs_to :account
  belongs_to :address

  accepts_nested_attributes_for :address

  default_scope :conditions => { :account_id => User.current.account }
end

当我运行 rake cucumber 时，我在 default_scope 行上收到一个关于帐户为零的错误。我的猜测是，当 Cucumber rake 任务运行时，它无法访问正确的应用程序控制器来注入 current_user 方法，因此 SentientUser 无法获取当前用户？我得到的错误是：
