小编use*_*152的帖子

我想用rails运行一个简单的MYSQL查询

Select movie-title, movie-director from moving order by rating desc limit 5;

我不想要所有开销创建模型.我只想运行查询.

做这个的最好方式是什么？
我甚至无法连接

这是我的控制器代码

ActiveRecord::Base.establish_connection ({
:adapter => "mysql2",
:host => "some-rds.amazon.com",
:username => "root",
:password => "root",
:database => "blah"})

这将生成此错误ActiveRecord :: ConnectionNotEstablished

谢谢
