Rails延迟工作不起作用 [英] Rails delayed job not working
本文介绍了Rails延迟工作不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的延迟工作不起作用。我正在尝试使用应该每15分钟运行一次的延迟作业为rake文件创建后台任务。我已将rake任务复制到rake文件中，并将其在控制器中设置为方法。我需要一份延迟的工作，因为heroku每1小时只会做一次cron。
My delayed job is not working. I am trying to create an background task for a rake file using a delayed job that should run every 15 minute. I have copied my rake tasks in my rake file and set them in my controller as methods. I need an delayed job because heroku only makes a cron every 1 hour.
这是我的应用程序控制器：
Here is my Application controller:
class ApplicationController < ActionController::Base
require 'delayed_job'
require 'Mechanize'
require 'pp'
protect_from_forgery
def iqmedier
agent = WWW::Mechanize.new
agent.get("http://www.iqmedier.dk")
form = agent.page.forms.first
form.submit
agent.page.link_with(:href => "/Publisher/Stats").click
form = agent.page.forms.first
form.submit
@stats = agent.page.search('//tr')[-2]
@existing = Reklamer.find(:first, :conditions => {:dato => @stats[0]})
if @existing.nil?
Reklamer.create!(:virksomhed => 'Iqmedier', :dato => @stats[0], :unik_klik => @stats[1], :klik => @stats[2], :unik_vis => @stats[3], :vis => @stats[4], :leads => @stats[5], :ordre => @stats[6], :cpc => @stats[7], :earn => @stats[8])

推荐答案
如果我正确理解了您要执行的操作，那么您应该具备以下条件：
If I understand correctly what you're trying to do, then you should have the following:
scraper.rb
require 'mechanize'
class Scraper
def perform
[:iqmedier, :euroads, :mikkelsen, :orville].each{|a| send(a)}
end
def iqmedier
# some code
end
def mikkelsen
# some code
end
def orville
# some code
end
end
在您的控制器中：
require 'delayed_job'
class MyController < ApplicationController
def runall
Delayed::Job.enqueue(Scraper.new, :run_at => 5.minutes.from_now)
end
end
要从Rails外部添加作业，您可以编写类似的内容，然后使用railsRunner运行它：
For adding jobs from outside of rails, you can write something similar and then run it with rails runner:
require 'scraper'
Delayed::Job.enqueue Scraper.new
Delayed::Job.enqueue Scraper.new, :run_at => 15.minutes.from_now
Delayed::Job.enqueue Scraper.new, :run_at => 30.minutes.from_now
Delayed::Job.enqueue Scraper.new, :run_at => 45.minutes.from_now
