问Rails: ActiveRecord在同一个模型上多次执行无意义查询

EN

在我的应用程序中，我已经覆盖了一些current_user设计方法。其思想是，如果存在某些cookie，则使用该cookie中的id检查组织，并返回该组织的所有者，而不是常规用户：

  def current_user
    user = warden.authenticate(scope: :user)
    return nil if user.nil?

    if user.admin? && cookies.key?('mock_admin_login')
      organization = Organization.includes(:creator).find(cookies.encrypted[:mock_admin_login])
      return organization.creator
    end
    user
  end 

所有操作都是正确的，但是当我查看我的控制台时，我注意到组织查询被多次执行：

虽然这似乎不是什么大事，但每次调用current_user方法时，服务器都会花费30到40 is来执行此操作。为什么这个查询被调用了那么多次而不是一个，我如何修复它？
