TypeError：沒有使用geokit-rails搜索將Symbol隱式轉換為Integer

Question

我已經在geocoder中安裝了geokit-rails gem，並使用正確的API密鑰和設置正確加載了我的配置。 我已經正確構造了ActiveRecord對象，該對象已使用浮點值對lat和lng列進行了編碼。 現在，我試圖簡單地搜索距給定起點100公里以內的場所（Venue activerecord）：

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

但是我一直收到錯誤：

TypeError: no implicit conversion of Symbol into Integer

有人幫忙嗎？

Answer 1

您可以通過docs直接在Lat＆Long的方法內使用Geokit。 Fe ：： :origin => [37.792,-122.393]. 在您的情況下， Venue.within(100, origin: [-27.12,124.2141])

為什么要為此使用Geokit :: LatLng.new？
