简单要实现的功能是：如果用户提交了一个表单，触发保存方法后就执行发送邮件通知。

controller代码：

if @work.save Usermailer.workcreated_email(@work).deliver_now format.html {redirect_to @work, notice: "Work Created"} format.js {} else format.html {render 'new'} format.js {} end

usermailer.rb:

class Usermailer < ApplicationMailer default from: "chaniel_test@163.com" def workcreated_email(work) @work = work mail(to: work.project.user.email, subject: "Work Item Posted") end end

console 报错：

Usermailer#workcreated_email: processed outbound mail in 31.5ms Completed 500 Internal Server Error in 127ms (ActiveRecord: 3.1ms) ActionView::MissingTemplate (Missing template usermailer/workcreated_email with "mailer".
