Question

我刚安装了[README.md][1]文件中提到的两个宝石。我有一个查询字符串，我想直接从localhost连接到数据库..有可能吗？

class Timelapse < ActiveRecord::Base
  establish_connection({
    :adapter  => "sqlserver",
    :host     => "myhostname.net",
    :username => "myusername",
    :password => "mypassword",
    :database => "mydbname"
  })
end

我去rails c试图做Timelapse.first并收到错误

使用这些Gem

这样连接

setp： - 1 gem＆＃39; tiny_tds＆＃39; gem＆＃39; activerecord-sqlserver-adapter＆＃39;

并使用git activerecord-sqlserver-adapter

进行检查

步骤：-2 发展：港口：1433 模式：dblib 适配器：sqlserver host：当dataserver为空时使用＃数据库：用户名：密码：超时：0

默认端口：1433＃默认为1433 默认模式：dblib 数据服务器：超时：5000 超时：0 - 没有超时天蓝色：真实的 dsn：

将SQL-Server直接连接到联机数据库rails activerecord-sqlserver-adapter
