我想知道如何有条件地放弃在ActionMailer操作本身中发送邮件.
- class SomeMailer < ActionMailer::Base
- ...
- def some_emails
- some_models = Model.where(:a => 1)
- if !some_models.blank?
- mail(...)
- else
- # What to add here?
- # render :nothing => true doesn't work
- end
- end
- end
现在通过SomeMailer.some_emails.deliver调用这个！返回
ArgumentError：发送消息所需的发送方(Return-Path,Sender或From)
解决方法
而是把你的条件放在你打电话给SomeMailer.some_emails.deliver的地方！
