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。

感谢。

Answer 1

经过几次尝试并查看我的.net连接通话后，我终于开始工作了。

我在独立脚本中使用activerecord。

此处有效的通话：

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服务器附带的配置工具会配置一个名为“mysql”的套接字。我已将其更改为mysql_test以验证我确实要查看命名管道。

干杯。

这不起作用

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）中断，错误：
