如何在rails job中访问rails helper方法current_user？

Question

我在Rails作业中有以下代码:

class MessageBroadcastJob < ApplicationJob
  queue_as :default

  def perform(message)
   ActionCable.server.broadcast "room_channel", message: render_message(message),msg: message, user: current_user
  end

  private
  def render_message(message)
    ApplicationController.renderer.render(partial: 'messages/message', locals: { message: message})
   end
end

正如你所看到的,我想传递current_user,但我无法访问设计Rails帮助方法.

ActiveJobs中没有设计辅助方法,你可以做的是将current_user id传递给perform方法,并在那里获取用户,例如

def perform(message, current_user_id)
  current_user = User.find(current_user_id)
  ActionCable.server.broadcast "room_channel", message: render_message(message),msg: message, user: current_user
end
