Rails 5 Active Job和Sidekiq不发送邮件

Question

因此，我对sidekiq和activejob还是陌生的，我知道我不需要后台处理在创建帐户时发送的邮件，但是我真的很想了解这一切是如何工作的，最好的学习方法就是这样做。 ..

我设置了以下作业，邮件程序和控制器操作，但是，当我创建一个新帐户时，该操作失败并显示错误：（为简洁起见，我发布了整个堆栈）

e_owner: processed outbound mail in 1.3ms

我的工作，邮件程序和控制器操作在此处：

    class WelcomeEmailJob < ApplicationJob
      queue_as :default

      def perform(account_id)
        @account = Account.find(account_id)
        WelcomeNotificationMailer.welcome_owner(@account).deliver_now
      end
    end

    class WelcomeNotificationMailer < ApplicationMailer

      def welcome_owner(account_id)
        account = Account.find(account)
        mail to: @account.owner.email, subject: 'Welcome to the PATROLVAULT family!'
      end

    end

class AccountsController < ApplicationController
      def create
        @account = Account.new(account_params)

        if @account.valid?
          Apartment::Tenant.create(@account.subdomain)
          Apartment::Tenant.switch!(@account.subdomain)
          @account.save

          WelcomeEmailJob.perform_now(@account.id)

          redirect_to login_url(subdomain: @account.subdomain), :flash => { notice: 'Account created successfully. Please check your email.' }
        end
      end
end

我已经坚持了一段时间，我敢肯定我看不到它。

提前感谢你的帮助！ 如果您需要更多信息，请告诉我。

Answer 1

在某种程度上，该应用程序运行太快。 在将帐户持久保存到数据库之前，将调用“欢迎电子邮件”作业。 您应该将作业移至模型中的after_create_commit挂钩。 即：

在您的/app/models/account.rb

class Account < ApplicationRecord
  after_create_commit :send_welcome_email

  ...

  def send_welcome_email
    WelcomeNotificationMailer.welcome_owner(self).deliver_now
  end
end

编辑：如果您想使其成为后台作业，只要正确配置了sidekiq（您有“邮件程序”队列），就可以调用deliver_later而不是deliver_now ，这应该可以解决问题
