delayed-job

问题 I've been trying to figure out how to send delayed mail using delayed_job with rails 3. I've tried pretty much every combination of feasible possibilities I can think of - I can get the mail to run in the background, I just can't get it to delay the sending to a future time. The delayed_jobs table in the db clears the tasks, the log says 'sent', the delayed_job task processor picks up the task & says sent without failure...but the mail is either: sent immediately, or simply doesn't arrive if

问题 Delayed::Job's auto-retry feature is great, but there's a job that I want to manually retry now. Is there a method I can call on the job itself like... Delayed::Job.all[0].perform or run, or something. I tried a few things, and combed the documentation, but couldn't figure out how to execute a manual retry of a job. 回答1: To manually call a job Delayed::Job.find(10).invoke_job # 10 is the job.id This does not remove the job if it is run successfully. You need to remove it manually: Delayed:

问题 Hey we have a library class (lib/Mixpanel) that calls delayed job as follows: class Mixpanel attr_accessor :options attr_accessor :event def track!() .. dj = send_later :access_api # also tried with self.send_later .. end def access_api .. end The problem is that when we run rake jobs:work: we get the following error: undefined method `access_api' for #<YAML::Object:0x24681b8> Any idea why? 回答1: Delayed_job always autoloads ActiveRecord classes, but it doesn't know about other types of

问题 I'm building an application that allows for large amounts of photo uploads at once, and wanted to know what the best setup would be to tackle this. This is what I am using so far: Jquery File Upload: allows users to drag and drop images CarrierWave: Processes images and resizes them with ImageMagick Amazon S3: CarrierWave uploads images to Amazon S3 through Fog Heroku: for hosting I'd like to allow users to be able to drag and drop a large amount of images onto a page, and then navigate to

问题 I'm developing a Rails 3.2.16 app and deploying to a Heroku dev account with one free web dyno and no worker dynos. I'm trying to determine if a (paid) worker dyno is really needed. The app sends various emails. I use delayed_job_active_record to queue those and send them out. I also need to check a notification count every minute. For that I'm using rufus-scheduler. rufus-scheduler seems able to run a background task/thread within a Heroku web dyno. On the other hand, everything I can find

问题 I'm using delayed_job (tried both tobi's and collective_idea's) on site5.com shared hosting, with passenger as rails environment. I managed to make jobs done. However, it seems the plugin ignores any changes in a job class source code after first run. I have restarted the server on every change ( touch tmp/restart.txt ) but it still ignores it. Example: file: lib/xx_job.rb class XxJob def perform Rails.logger.info "XX START" TempTest.delete_all i = 0 10.times { i+=1 TempTest.create(:name =>

问题 I have deployed rails app on two EC2 instances. I have scheduled on Job with rufus-scheduler to run every 24 hours to send some emails. But scheduler is running separately on two instances. I need run scheduler on only one instance. So can you please help with this issue? Thanks 回答1: Let's assume you've followed https://github.com/jmettraux/rufus-scheduler#so-rails You could modify the initializer in this way: # # config/initializers/scheduler.rb require 'rufus-scheduler' s = Rufus::Scheduler

问题 In delayed_jobs it is possible to run a worker for a specific queues. I can't seem to find any examples/documentation on how to run a worker and exclude a specific queue. I am trying to have 1 worker for super high priority stuff and 1 that handles the rest. Is the only way to achieve this by specifying what queues relate to what worker? Is there no way to spawn a worker that runs all queues except queue_x? 来源： https://stackoverflow.com/questions/46073051/exclude-queue-from-delayed-job-worker

问题 Edit: I'm using Rails 3.2.17 and Ruby 2.0.0p0 I've been having some issues with ActionMailer timing out on sending mail; See ActionMailer Timing out After increasing the default Unicorn timeout to 2min (for testing) It completes in about 45 sec. I thought the best way to handle this would be to use Delayed Job , however, when DJ runs the deliver method it's timing out too. Stack trace below. Is DJ the right tool for the job? Do I need to increase the timeout for DJ (I thought that I had read
