gem gmaps4rails =>(2.1.1)
db table
:latitude, :float
:longitude, :float

嗨！每次我保存纬度＆＃39;和经度＆＃39;属性进入db保存的数据略有不同或完全不同。例如：

示例：13 Rue Jules-Verne，蒙特利尔，QC：纬度：45.507147 经度：-75.63314

https://maps.google.ca/maps?q=13+Rue+Jules-Verne,+Montreal,+QC&hl=en&sll=45.507147,-75.63314&sspn=0.007925,0.019741&oq=13,+rue+Jules-Verne+mo&hnear=13+Rue+Jules-Verne,+Montreal,+Quebec+H2R&t=m&z=16

Answer 1

您使用的lat long值可能与您提交的地址不同。地理编码器获取一个地址并将其转换为lat long，这可能会覆盖lat而不是你的总和

gmaps4rails：纬度和经度无法在数据库中正确保存
