为#<User:0x设计可邀请的重新排队作业失败-未定义的方法`invitation_instructions

Question

Ruby on Rails项目，我正在运行Resque来处理电子邮件(特别是设计和设计可邀请的)。Devise电子邮件发送正常(通过API通过邮戳gem发送)，但devise_invitable电子邮件在使用undefined method invitation_instructions for #User:0x0xxxxxx Did you mean? invitations_count的Resque中失败。

当通过默认的设计邮件程序发送时，一切正常，但与我的自定义邮件程序失败。我想添加一个内联附件，因此需要一个自定义邮件程序。

自定义Devise Mailer：

class DeviseMailer < Devise::Mailer
    helper  :application

    include Devise::Controllers::UrlHelpers
    include Devise::Mailers::Helpers
    include DeviseInvitable::Mailer

    default template_path: 'devise/mailer'
    default from: sender@example.com
    layout  'mailer_devise'

    before_action :add_inline_attachment!

    def reset_password_instructions(record, token, opts={})
        super
    end

    def invitation_instructions(record, token, opts={})
        @token = token
        devise_mail(record)#, record.invitation_instructions || :invitation_instructions, opts)
      end

    private

    def add_inline_attachment!
        attachments.inline['logo.png'] = File.read(Rails.root.join('app/assets/images/logo.png'))
    end
end

摘要：

def reset_password_instructions -工作正常

def invitation_instructions -失败，出现未定义的方法错误

Answer 1

我最终因为其他原因迁移到了Sidekiq。下面是我更新后的Devise Mailer类，运行良好。不需要定义invitation_instructions方法，因为before_action回调正在附加内联图像，这就是我在开始时要做的。

class DeviseMailer < Devise::Mailer
  helper  :application
  include Devise::Controllers::UrlHelpers
  include Devise::Mailers::Helpers
  include DeviseInvitable::Mailer

  default template_path: 'devise/mailer'
  default from: ENV['EMAIL_NAME']
  layout  'mailer_devise'

  before_action :add_inline_attachment!

  private

  def add_inline_attachment!
    attachments.inline['logo.png'] = File.read(Rails.root.join('app/assets/images/logo.png'))
  end
end
