heroku - postgres - 运营商不存在

我决定给heroku一个尝试（以节省时间），但我发现他们使用我知之甚少的PostgreSQL。 geocoder gem在MySQL中效果很好，但是PostgreSQL正在抛出一个错误。heroku - postgres - 运营商不存在

我觉得这个错误是说拉特没有定义？

你需要将其强制转换：

37.358151 - lat::numeric

我该怎么做？ – OneChillDude 2013-08-20 23:40:17

我有一个类似的错误。这是由我在我的迁移中指定的外部id作为字符串而不是整数。

要解决它，我改变了：

create_table :these_objects do |t| 
    t.string:user_id 
end

到

create_table :these_objects do |t| 
    t.integer :user_id 
end

SQLite在开发过程中从未抱怨过它，但Postgres做过。 – LikeMaBell 2012-01-12 16:24:57

SQLite的类型系统相当宽松，PostgreSQL的不是。解决方案是（如您所说）在任何地方和理想情况下使用适当的类型，并在您部署的同一数据库之上进行开发。 – 2012-01-12 19:00:12

我有同样的问题。您可能会将您的纬度和经度字段设置为字符串，因此您需要检查您的移动文件中是否包含经纬度字段。

create_table :place do |t| 
    t.text :name 
    t.float :latitude 
    t.float :longitude 
    t.timestamps 
end
