Ruby on rails Google maps for Rails-未定义的方法'gmaps'；用于rake任务中的（对象）

当我运行一个rake任务，其中涉及启用了gmaps4rails的模型时，我得到了这个错误，如果我对该模型进行注释，使其不可作为gmappable，它将正确完成

任务：TOP=>填充：扫描

解决方案1：

acts_as_gmappable :process_geocoding => false

解决方案2：

创建模型实例时，请执行以下操作：

@scan.instance_eval do
  def process_geocoding
    true
  end
end

您的模型中是否有“gmaps”专栏或方法？抱歉-此网站没有发送电子邮件通知-我邀请您参加一个项目以查看一些代码-如果您有时间检查，我们可以在此处发布更新为什么需要？这是与Ruby 1.9或Ruby不兼容吗
