Question

我使用Resque w / Redis在Rails 4上。

我的问题：如何在我的后台作业中使用当前在application_controller中定义的控制器方法？

这是我定义的当前方法：

def push_to_google(token, message)
  if token.present?
    gcm = GCM.new("843jf9384fj839f848j890fj3")
    registration_ids = ["#{token}"] # an array of one or more client registration tokens
    options = {data: {notification: "#{message}"}}
    response = gcm.send(registration_ids, options)
  end
end

我想在我的delayed_notifications中定义的后台作业中使用：

class DelayedNotifications
  @queue = :notifications_queue

  def self.perform(registration_id, user_name)
    push_to_google(registration_id, "New message from #{user_name}.")
  end
end

当然，我的工作目前无法解决此错误：

undefined method 'push_to_google' for DelayedNotifications:Class

提前感谢您的帮助。

将push_to_google提取（移动）到ApplicationHelper，并在ApplicationHelper和ApplicationController中添加DelayedNotifications。

更改后，您的application_helper.rb应为：

module ApplicationHelper
  # other methods

  def push_to_google(token, message)
    if token.present?
      gcm = GCM.new("843jf9384fj839f848j890fj3")
      registration_ids = ["#{token}"] # an array of one or more client registration tokens
      options = {data: {notification: "#{message}"}}
      response = gcm.send(registration_ids, options)
    end
  end
end

application_controller.rb：

class ApplicationController < ActionController::Base
  include ApplicationHelper

end

delayed_notifications.rb：

class DelayedNotifications
  include ApplicationHelper

  @queue = :notifications_queue

  def self.perform(registration_id, user_name)
    push_to_google(registration_id, "New message from #{user_name}.")
  end
end

使用Resque后台作业的控制器方法
