NoMethodError:未定义的方法`deliver_now' [英] NoMethodError: undefined method `deliver_now'

问题描述

我的控制器中有这个:

  def create
    @user = User.new(user_params)
    if @user.save
      UserMailer.account_activation(@user).deliver_now
    ....
  end

而且我不断收到此错误:

And I keep getting this error:

NoMethodError: undefined method `deliver_now' for #<ActionMailer::MessageDelivery:0x007ffa6646eb60>

知道为什么没有找到 Deliver_now 方法吗?

Any ideas why it's not finding the deliver_now method?

推荐答案

deliver_now 已在 rails 4.2.beta2 中引入.您可能使用的是早期版本.

deliver_now has been introduced in rails 4.2.beta2. You are probably using earlier version.
