ActiveRecord 在 Windows 上使用 mysql 命名管道

Question

是否可以通过命名管道从 ruby​​/ActiveRecord 连接到 mysql 数据库。 操作系统是 Windows。

谢谢。

Answer 1

经过几次尝试并查看了我的 .net 连接调用后，我终于可以正常工作了。

我在独立脚本中使用 activerecord。

这是有效的调用：

ActiveRecord::Base.establish_connection(
    :adapter => "mysql",
    :host => ".",
    :username => "root", 
    :password => "root", 
    :database => "test",
    :socket => "mysql_test")

请注意，默认情况下，mysql服务器自带的配置工具会配置一个名为“mysql”的socket。我已将其更改为 mysql_test 以验证我确实正在检查命名管道。

干杯。

这不行

Ruby 版本：1.9.1 mysql版本：5.0

编写的代码是：

    require "rubygems"
    require "active_record"
    puts "1"
    class Source < ActiveRecord::Base
        puts "2"
        establish_connection(
                :adapter => "mysql",
                :host => "localhost",
                :username => "root",
                :password => "root@123",
                :database => "TrafficTracker"
            )
    end
    puts "3"
    traffic_source = Source.find(1)
    puts "4"
    puts traffic_source.source_name

上面的代码打印到 3 并在 Source.find(1) 处中断并出现错误：
