Delayed::Web for Delayed::Job

A rails engine that provides a simple web interface for exposing the Delayed::Job queue.

Requirements

• Ruby 2.2.x, 2.3.x
• Rails 3.2.x, 4.0.x, 4.1.x, 4.2.x, 5.0.x, 6.x
• Delayed::Job 3.0.x, 4.0.x
• ActiveRecord or Mongoid

Installation

Put this in your Gemfile.

gem 'delayed-web'

Run bundler.

bundle install

Run the installation generator.

rails generate delayed:web:install

This will install an initializer into config/initializers/delayed_web.rb, mount the engine at /jobs in config/routes.rb and add the stylesheets to the list of precomiled assets in application.rb (If assets are enabled).

Routes

The installation script will automatically add routes into your app, like this.

# config/routes.rb
Rails.application.routes.draw do
  mount Delayed::Web::Engine, at: '/jobs'
end

This will mount the following routes.

GET /
GET /jobs
GET /jobs/:id

Authentication

Out of the box Delayed::Web doesn't make any assumptions about authentication. It's possible to take advantage of rails routing constraints or rack middleware.

An example using Devise's authenticated constraint.

# config/routes.rb
authenticated :user, -> user { user.admin? } do
  mount Delayed::Web::Engine, at: '/jobs'
end

An example using Rack::Auth::Basic.

# config/routes.rb
Delayed::Web::Engine.middleware.use Rack::Auth::Basic do |username, password|
  username == ENV['USERNAME'] && password == ENV['PASSWORD']
end

Backend

The installation script will automatically set the backend you're using for Delayed::Job, like this.

# config/initializers/delayed_web.rb
Rails.application.config.to_prepare do
  Delayed::Web::Job.backend = 'active_record'
end

Currently supported backends are 'active_record' and mongoid'. Patches are always welcome.

Asset Pipeline

The installation script will automatically add the engine's assets to your application's list of precompiled assets.

# config/application.rb
config.assets.enabled = true
config.assets.precompile << 'delayed/web/application.css'

This step is skipped if your project is configured not to use the asset pipeline.

I18n

If you want to translate flash messages, titles, or sentences you can set your own I18n translations to override defaults one:

en:
  delayed/web:
    views:
      id: ID
      status: Status
      created_at: Created At
      run_at: Run At
      attempts: Attempts
      last_error: Last Error

🇬🇧 English, 🇪🇸 Spanish, 🇫🇷 French, 🇩🇪 German, and 🇧🇷 Portuguese are supported. You can find the full list here.

Developing Locally

After you've cloned the repository, run bundler.

bundle install

Make sure the specs are passing.

rake

Run the dummy rails app.

cd spec/dummy
rails s

Go to http://localhost:3000.

The dummy rails app uses Delayed::Web::Job::Double as its backend. It is an in-memory double of a real Delayed::Job.
