Rails4验证唯一性范围检查两个以上的条件

Question

我在模型

中对我的电子邮件进行了以下验证

:uniqueness => { :scope => :company_id, :message => "Email has already been taken" }

如何为验证唯一性提供两个范围条件

：uniqueness =＆gt; {：scope =＆gt; :company_id and :status => 0，：message =＆gt; “已经收到电子邮件”}

Answer 1

试试这个

:uniqueness => { :scope => [:company_id, :status], :message => "Email has already been taken"}, if: Proc.new { |obj| obj.status == 0 }
