sidekiq

问题 I get the following error when loading a sidekiq queue: RuntimeError: Circular dependency detected while autoloading constant FileProcessor /Users/johnmcauley/.rvm/gems/ruby-2.2.2/gems/activesupport-4.2.0/lib/active_support/dependencies.rb:492:in `load_missing_constant' /Users/johnmcauley/.rvm/gems/ruby-2.2.2/gems/activesupport-4.2.0/lib/active_support/dependencies.rb:184:in `const_missing' /Users/johnmcauley/.rvm/gems/ruby-2.2.2/gems/activesupport-4.2.0/lib/active_support/dependencies.rb:526

问题 We are in need of a queuing system in our Ruby On Rails 4 web application what are the differences and why would/wouldn't you pick Sidekiq over RabbitMQ ? 回答1: It's quite different things with different usage. Sidekiq is full-featured solution for job queueing and processing, while RabbitMQ is just a message broker where you can build your own stuff upon it. 来源： https://stackoverflow.com/questions/34525941/sidekiq-vs-rabbitmq

问题 I have several scheduled jobs running like this: MyWorker.perform_at(3.hours.from_now, 'mike', 1) I am wondering, if later, say an hour later, I feel like I want to cancel this job, how would I go about doing that? 回答1: I've recently written a bit of code to handle this, it's available in my branch of the sidekiq-status gem. You can view it, or use it here: https://github.com/Robinson7D/sidekiq-status (You would have to use that as the git: information in the gemfile, currently, until the

问题 How can I run sidekiq as daemon on Ubuntu? If I run bundle exec sidekiq -D I get invalid option: -D , is there any way to run it without some other controller, like god, upstart...? 回答1: there's an option to Daemonize sidekiq, just pass -d option commit 回答2: Running as daemon won't restart the sidekiq if it crashes unexpectedly. One alternate way could be to run sidekiq as a service (An upstart job). If the system is rebooted than also the upstart job will run sidekiq. Here is the complete

问题 Does anyone know how to find sidekiq's pidfile to gracefully shut it down? Running ps ax | grep sidekiq and then running sidekiqctl stop <pid from grep> consistently gives a no such pidfile error? Cntl-C and Cntl-D also seem to have no effect. Closing the process window and reopening a new window doesn't kill the process as it appears to be running as a daemon. The only consistent fix I've found is rebooting. 回答1: Use this to kill sidekiq forcefully. ps -ef | grep sidekiq | grep -v grep | awk

问题 I'm trying to use a sidekiq worker, which more or less saves a image file to database (using carrierwave). There are few files to save, which are a keyframes extracted from a video file. That's what that worker is about. My image uploader has a few versions defined and looks as follows: class KeyframeUploader < CarrierWave::Uploader::Base # ... # Keyframe thumbnail sizes version :small do process resize_to_fill: [180, 180], if: :square? process resize_to_fill: [320, 180], if: :not_square? end

问题 faced with an issue where @user.reset_token returns nil. app/views/user_mailer/password_reset.html.erb <%= link_to "Reset password", edit_password_reset_url(@user.reset_token, email: @user.email) %> Reset_token is declared in User model, whereby this problem happens when I try to use a sidekiq worker. Refer to code below. app/models/user.rb class User < ActiveRecord::Base attr_accessor :reset_token def User.new_token SecureRandom.urlsafe_base64 end def send_password_reset_email

问题 I have a sidekiq worker that fires after an object is saved: class Post < ActiveRecord::Base attr_accessible :description, :name, :key after_save :process def process ProcessWorker.perform_async(id, key) if key.present? end def secure_url key.match(/(.*\/)+(.*$)/)[1] end def nonsecure_url key.gsub('https', 'http') end end The worker looks like the following (it's not complete yet... just testing): class ProcessWorker include Sidekiq::Worker def perform(id, key) post = Post.find(id) puts post

问题 I'm building a Tinder style app where users can swipe through events. Currently, I have a background job that is being fired any time a user swipes an event. With users swiping through 20 events per minute, I'm creating a ton of background jobs: worker.rb class Worker include Sidekiq::Worker def perform(user_id, newly_voted_event_id) user = User.find(user_id) event = Event.find(newly_voted_event_id) events_to_rerank = event.similar.unvoted(user_id) events_to_rerank.each do |e| e.rank(user_id)

问题 Jobs in sidekiq are suppose to check if they have been cancelled, but if I have a long running job, I'd like for it to check itself periodically. This example does not work : I've not wrapped the fake work in any sort of future within which I can raise an exception -- which I'm not sure is even possible. How might I do this? class ThingWorker def perform(phase, id) thing = Thing.find(id) # schedule the initial check schedule_cancellation_check(thing.updated_at, id) # maybe wrap this in
