Rails 电子邮件传递检查错误 - deliver_now

Rails Error Checking for Email Delivery - deliver_now

我应该如何包装 deliver_now 方法调用，以便我们可以在交付时发现错误？

@user = User.new(user_params)
if @user.valid?
  MyMailer.user_email(@user).deliver
  # hmmm....  how do we catch if the email is not sent?  
else
  ...
end

确保您在应用程序配置中设置了 config.action_mailer.raise_delivery_errors = true。然后您可以使用救援块捕获异常。像这样：

@user = User.new(user_params)
if @user.valid?
  begin
    MyMailer.user_email(@user).deliver
  rescue StandardError => e
    # do something with the messages in exception object e
    flash[:error] = 'Problems sending email'
  end
else
  ...
end
