Ruby on rails Mysql2:：对象的结果

如何将Mysql2:：Result转换为某个对象？ 我使用：

我需要将这个结果映射到某个对象，或者像这样的smthg。

谢谢。

我的理解是，您可以在任何模型上执行类似的sql查询，它将作为该模型的实例返回数据。仔细阅读。这是文档中的示例。请注意，is返回一个Post对象：

Post.find_by_sql "SELECT p.title, c.author FROM posts p, comments c WHERE p.id = c.post_id"
> [#<Post:0x36bff9c @attributes={"title"=>"Ruby Meetup", "first_name"=>"Quentin"}>, ...]

---

谢谢，我如何将两个或多个参数传递给find_by_sql方法？问题已解决。find_by_sql（[sql，'2011-04-06'，1]）我在回答中添加了一个示例。

Post.find_by_sql "SELECT p.title, c.author FROM posts p, comments c WHERE p.id = c.post_id"
> [#<Post:0x36bff9c @attributes={"title"=>"Ruby Meetup", "first_name"=>"Quentin"}>, ...]

irb(main):015:0> y Location.find_by_sql(["select address, name from locations where name = :name and address = :address", {:address => "Arts Court 2 Daly Ave, Ottawa, ON", :name => "Studio B"}])
