Mongoid OR查询语法 [英] Mongoid OR query syntax

问题描述

必须对此进行很多询问，但文献记录很少.在 http://mongoid.org/en/mongoid/docs/querying中没有提及. html

This must be asked alot but it is very poorly documented. There is no mention at http://mongoid.org/en/mongoid/docs/querying.html

我正在尝试检查用户是否存在(下面是AND查询)，如何将其更改为OR类型的查询

I'm trying to check whether a user exists (below is an AND query), how can I change it to an OR type query

Username.where(:username=>@username, :email=>@email)

(电子邮件或用户名必须匹配).

(Either the email or the username must match).

我发现了一些非常复杂的在线方法，包括发送直接javascript(从): http://omarqureshi.net/articles/2010-6-17-using-or-in-mongoid

I have found some pretty complicated ways online including sending a direct javascript (from): http://omarqureshi.net/articles/2010-6-17-using-or-in-mongoid

肯定要有一个简单的清晰语法才能正确执行此操作?

Surely there must be a simple clear syntax to do this correctly?

推荐答案

是的，以前有更好的记录.试试这个:

Yeah, this used to be documented better. Try this:

Username.any_of({:username => @username},
                {:email => @email})
