我已经使用地理编码器安装了 geokit-rails gem，并使用正确的 API 密钥和设置正确加载了我的配置。我已经正确构造了具有编码的 ActiveRecord 对象lat和lng具有浮点值的列。现在我试图简单地搜索在给定原点 100 公里范围内的场地（场地活动记录），如下所示：

Venue.within(100, origin: Geokit::LatLng.new(-27.12,124.2141))

然而我一直收到错误：

TypeError: no implicit conversion of Symbol into Integer

有人会帮忙吗？

You could use Geokit within method with Lat&Long directly - from docs. F.e: :origin => [37.792,-122.393]. In your case Venue.within(100, origin: [-27.12,124.2141])

Why do you use Geokit::LatLng.new for this?
