Deliver_later 使用 sidekiq rails

Question

我尝试使用 sidekiq 执行 Deliver_later，但收到错误消息。

这是我的设置

* execute redis
redis-server

* execute sidekiq
bundle exec sidekiq -q default -q mailers

* Gemfile
gem 'sidekiq'


* application.rb
config.active_job.queue_adapter = :sidekiq


#send email
 UserMailer.account_activation(@user).deliver_later

我不知道如何解决这个问题。 这是错误信息

Answer 1

我猜你是按照《ruby on rails tutorial》这本书，如果我们用deliver_now运行代码，结果会正确，但是如果我们用deliver_later运行代码，就会显示错误顶部。 阅读活动工作指南后，我知道活动工作使用 GlobalID，这使得将实时 Active Record 对象传递给您的工作而不是类/ID 对成为可能。

在《ruby on rails教程》一书中，activation_token属性是虚拟属性

class User < ApplicationRecord
  attr_accessor :activation_token
end

活动作业使用用户对象作为参数，用户对象将作为例外发送，但虚拟属性会丢失，方法如下：

1. 保留activation_token 属性或
2. 单独传输activation_token属性

class UserMailer < ApplicationMailer
  def account_activation(user, activation_token)
    @user = user
    @activation_token = activation_token
    mail to: user.email, subject: "user activation"
  end
end

UserMailer.account_activation(user, user.activation_token).deliver_later

<p><%= link_to "active link", edit_account_activation_url(@activation_token, email: @user.email) %></p>

Answer 2

这是错误

2016-11-18T17:13:50.414Z 41513 TID-oxh5ccnb8 WARN: ActionView::Template::Error: No route matches {:action=>"edit", :controller=>"account_activations", :email= >"chandleryang76@gmail.com", :id=>nil} 缺少必需的键：[:id]

您的邮件视图出错了。在某个地方你有这样的东西

edit_account_activation_path(@activation)

其中@activation 为零。因此错误。没有对象，编辑路径无效。

Answer 3

邮件视图有错误。 您需要检查以 nil 形式传递的 @activation 对象。

Answer 4

如果您正在使用 sidekiq，请不要稍后使用 Deliver，因为该作业永远不会执行，而是使用 perform_in() 并使用内部的方法 deliver_now 调用工作人员
