Requirements

  • Ruby 3.0.2

Working with Bundler and RBENV

This project manages RBENV and manages dependencies via Bundler.

You must first install RBENV. Then install Ruby 3.0.2 via RBENV ``` shell script rbenv install 3.0.2

You'll now notice that this project (as well as other App47 ones) contains a .ruby-version file, which is executed upon opening the project's root directory in a terminal (and IDE's like RubyMine). The .ruby-version file simply states `2.7.0` which tells RBENV to ensure the Ruby version to use for this project is 2.7.0.

Please note, your Ruby `3.0.2` version might need bundler installed:
``` shell script
gem install bundler -v 2.5.4

To set up this project's dependencies, which are defined in the file, Gemfile, you should first run ``` shell script bundle install 


## Development

Your `RubyMine` environment should be setup now, however to verify all is well, please run the test suite
``` shell script
bundle exec rake test

Deployment

The web47core project is a gem that will be deployed via Ruby Gems. When an update is ready, the following steps should be followed

  1. Build the gem gem build web47core.gemspec
  2. Post the gem to the DevOps channel in slack, ask for it to be added to the S3 repo.

Usage

Importing the gem

To use the web47core gem in a project, first add the gem to your Gemfile in one of two ways

Using the gem from Ruby Gems

gem 'web47core'

If you need the gem immediately or need to pull from development branch, you can use the git repo

gem 'web47core', git: '[email protected]:App47/web47core.git', branch: :master

or from the develop branch

gem 'web47core', git: '[email protected]:App47/web47core.git', branch: :develop

Please do not ship to production code using the git repo, as the production servers will not have keys to pull from the web47core repo.

Remove the following files

  1. StandardModel - Includes the common set of includes, Mongoid, Auditable, AutoClearCache, etc.
  2. CdnUrl - Provide CDN URLs of your classes URLs when cdn_url is configured in system configuration
  3. AutoClearCache - Clears your objects cache out of Rails.cache using the object's id
  4. Formable - Consolidated into StandardModel, was used to provide common form operations for mongoid documents
  5. EmailNotification
  6. EmailTemplate
  7. Notification
  8. NotificationTemplate
  9. SlackNotification
  10. SmsNotification
  11. Template
  12. App47Logger and App47LoggerTest
  13. Emailable or EmailAble and EamailbleTest, be sure to change Emailable to EmailAble
  14. RedisConfiguration and RedisConfgurationTest
  15. Searchable and SearchableTest, be sure to change Searchable to SearchAble
  16. TimezoneAble and TimezoneAbleTest
  17. CronJobServer and CronJobServerTest
  18. JobCronTab and JobCronTabTest
  19. CronTab
  20. SecureFields
  21. Job
  22. JobLog
  23. CommandLogLog
  24. TrimJobs #### Models ##### Concerns
  25. StandardModel - Includes the common set of includes, Mongoid, etc.
  26. CoreSystemConfiguration - Base system configuration to be included in the app's SystemConfiguration Object
  27. CoreAccount - Base account object that is related to notifications and the ilk. ##### System Configuration Define a SystemConfiguration class in your project and import the core concern.
class SystemConfiguration
  include StandardModel
  include CoreSystemConfiguration

  # Include your additional system configuration fields and methods
  field :google_sso_client_id, type: String
end

Configuration has been broken out, or modularized as of 2.0.10, so if the project uses AWS, SMTP, Slack, Switchboard, Twilio or Zendesk within SystemConfiguration, then you will also need to include those configurations in the Project's SystemConfiguration, for example

class SystemConfiguration
  include StandardModel
  include CoreSystemConfiguration
  include ZendeskConfiguration
  include TwilioConfiguration
  include SwitchboardConfiguration
  include DelayedJobConfiguration

  # Include your additional system configuration fields and methods
  field :google_sso_client_id, type: String
end
Account

Define a Account class in your project and import the core concern.

class Account
  include StandardModel
  include CoreAccount

  # Include your additional system configuration fields and methods
  has_many :users
end
Cron

Cron infrastructure for running jobs every minute, hour, day, week, month or some combination

  1. Remove config/initializers/job_cron_tabs.rb that was previous used to ensure cron tabs, they will be loaded automatically now
  2. Remove the Delayed::Backend::Mongoid::Job class definition, not the settings from config/initializers/delayed_job.rb, these are included in this gem now.
  3. Cron jobs should extend from Cron::Job now and specify cron_tab_entry within the class. ruby module Cron class MyJob < Job cron_tab_entry :daily def perform # do your work end end end Allowed values of cron_tab_entry are
  4. :always Run every minute
  5. :hourly Run every hour
  6. :daily Run every day
  7. :weekly Run every week on Sunday
  8. :monthly Run every month on the first day of the month
  9. '*/5 1,3 * 2 *' Run according to unix crontab entry format. This would run every tuesday on the 1st and 3rd hour, for any minute divisible by 5, so 0, 5, 10, 15, etc..

Before starting the server, you need to run the database command 

db.cron_tabs.updateMany({_type: 'JobCronTab'}, {$set: {_type: 'Cron::JobTab'}});

Abilities

Update abilities to new class names CronTab, JobCronTab, CronJobServer to Cron::Tab, Cron::JobTab, Cron::Server

Routes

The following routes should be added to the correct namespace for your applicaiton

    #
    # Cron job servers and Cron Tabs
    # index - show both cron tabs and servers
    # edit - edit a cron tab
    # update - update a cron tab
    # destroy - destroy a server
    # demote - demote a server
    # run_now - run a cron tab
    #
    resources :cron, only: %i[edit update destroy index] do
      member do
        get :run_now
        get :demote
      end
    end
    #
    # System configuration
    #
    resource :system_configurations, only: %i[edit update show] do
      get :sync
    end
    #
    # Delayed jobs
    #
    resources :delayed_jobs, only: %i[index show destroy] do
      collection do
        get :resubmit_all
        get :destroy_all
      end
      member do
        get :resubmit
      end
    end

Controllers

CronController

Update the CronController with something like below, and remove the views and any localization you might have made.

# frozen_string_literal: true

#
# Manage all crontabs in the system Configuration
#
class CronController < AdminController
  load_and_authorize_resource :cron_tab, only: %w[run_now update edit], id_param: :id, class: 'Cron::Tab'
  load_and_authorize_resource :cron_server, only: %w[demote destroy], id_param: :id, class: 'Cron::Server'
  include ::CoreCronController
  rescue_from Mongoid::Errors::DocumentNotFound, with: :document_not_found_error
end

To start or stop the cron server, run the bundler command:

bundle exec cron_server start

or 

bundle exec cron_server stop
DelayedJobController

Update the DelayedJobController with something like below, and remove the views and any localization you might have made.

# frozen_string_literal: true

#
# Manage access to delayed jobs for the admin UI
#
class DelayedJobsController < AdminController
  include ::CoreDelayedJobsController
  load_and_authorize_resource class: 'Delayed::Backend::Mongoid::Job'
  rescue_from Mongoid::Errors::DocumentNotFound, with: :document_not_found_error
end

To start or stop the delayed jobs, run the bundler command:

bundle exec delayed_job start

or

bundle exec delayed_job stop
Delayed Job Management

Since 2.1.0, there is now a built in Delayed Job monitor that will monitor delayed jobs and auto restart them if they exceed the max allowed time for a job to run. To configure this, update the delayed job initializer to add the TimeKeeper plugin.

Delayed::Worker.plugins += [Delayed::Plugins::TimeKeeper]

This will add a few now cron jobs as well as objects to the project, you can view these by adding the following routes near the delayed jobs area

resources :delayed_job_workers, only: %i[index destroy]
resources :delayed_job_metrics, only: %i[index destroy]

with the following two controllers

# frozen_string_literal: true

#
# Manage access to metrics
#
class DelayedJobMetricsController < BaseStackUiController
  rescue_from Mongoid::Errors::DocumentNotFound, with: :document_not_found_error
  include ::CoreDelayedJobMetricsController
end

and

# frozen_string_literal: true

#
# Manage access to workers
#
class DelayedJobWorkersController < BaseStackUiController
  rescue_from Mongoid::Errors::DocumentNotFound, with: :document_not_found_error
  include ::CoreDelayedJobWorkersController
end

lastly, add the following three objects to ability to allow access

  Delayed::Jobs::Worker,
  Delayed::Jobs::Metric,
  Delayed::Jobs::Run
StatusController

Remove controller, views and localizations

SystemConfigurationsController

Update the SystemConfigurationsController with something like below, and remove the views and any localization you might have made.

# frozen_string_literal: true

#
# Manage the system configuration page
#
class SystemConfigurationsController < AdminController
  include ::CoreSystemConfigurationsController
  load_and_authorize_resource :system_configuration
end

~/bin Directory

Remove the delayed_job, delayed_job.sh and cron_server.sh files

Notification Templates

Move any notification templates from ~/app/assets/templates to ~/lib/templates
