所以我对sidekiq和activejob很新，我知道我不需要在创建帐户时发送邮件的背景工作，但我真的想了解这一切是如何工作的，最好的学习方法是做...
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它失败并显示错误:(为简洁起见，我已发布整个堆栈）

我的工作，邮件和控制器操作在这里：
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，我确信这是我无法看到的。
预先感谢您的协助！如果您需要更多信息，请与我们联系。
答案 0 :(得分：4)
应用程序在某种程度上过快了。在将帐户持久保存到数据库之前，正在调用欢迎电子邮件作业。您应该将作业移动到模型中的after_create_commit挂钩。即：
在/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：如果你想让它成为一个后台工作，只要你的sidekiq配置正确（你有一个'邮件程序'队列），你可以打电话给deliver_later而不是deliver_now那个应该做的伎俩
