Question

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浮点值的lat和lng列编码的ActiveRecord对象。现在我试图简单地搜索距离给定原点100公里范围内的场地（Venue activerecord）：

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
    from /usr/local/lib/ruby/gems/2.1.0/gems/geocoder-1.2.3/lib/geocoder/sql.rb:14:in `[]'

有人会帮忙吗？

你可以直接在Lat＆amp; Long的方法中使用Geokit - from docs。 F.e： :origin => [37.792,-122.393]. 在您的情况下Venue.within(100, origin: [-27.12,124.2141])

为什么要使用Geokit :: LatLng.new？

TypeError：没有使用geokit-rails将Symbol隐式转换为Integer进行搜索
