Installation

gem 'active_interaction-extras'

Basic Usage

# app/services/application_interaction.rb
class ApplicationInteraction < ActiveInteraction::Base
  include ActiveInteraction::Extras::All
end

Filters

These new filters are added automatically when gem is loaded.

Anything

Anything filter accepts as you guest it - anything.

class Service < ActiveInteraction::Base
  anything :model
end

UUID

class Service < ActiveInteraction::Base
  uuid :id
end

Filter Extensions

You can load all filter extensions with:

# config/initializers/active_interaction.rb
require 'active_interaction/extras/filter_extensions'

Hash: auto strip

This small extensions allows to accept full hashes without explicit strip option.

class Service < ActiveInteraction::Base
  hash :options_a, strip: false # (Before) Accept all keys
  
  hash :options_b # (After) Accept all keys
  
  hash :options_c do # (Before and After) Accept only specified keys
    string :name
  end
end

Object: multiple classes

This extension allows using object filter with multiple classes.

class Service < ActiveInteraction::Base
  object :user, class: [User, AdminUser]
end

Extensions

Filter Alias

class Service < ActiveInteraction::Base
  include ActiveInteraction::Extras::FilterAlias
  
  hash :params, as: :user_attributes

  def execute
    user_attributes == params # => true
  end
end

Halt

class Service < ActiveInteraction::Base
  include ActiveInteraction::Extras::Halt

  def execute
    other_method
    puts('finished') # this won't be called
  end

  def other_method
    errors.add :base, :invalid
    halt! if errors.any?
    # or
    halt_if_errors!
  end
end

ModelFields

class UserForm < ActiveInteraction::Base
  include ActiveInteraction::Extras::ModelFields

  anything :user

  model_fields(:user) do
    string :first_name
    string :last_name
  end

  def execute
    model_fields(:user)                   # => {:first_name=>"Albert", :last_name=>"Balk"}
    any_changed?(:first_name, :last_name) # => true
    given_model_fields(:user)             # => {:first_name=>"Albert"}
    changed_model_fields(:user)           # => {:first_name=>"Albert"}
  end
end

user = OpenStruct.new(first_name: 'Sam', last_name: 'Balk')

UserForm.new(user: user).first_name # => 'Sam'
UserForm.run!(user: user, first_name: 'Albert')

RunCallback

class Service < ActiveInteraction::Base
  include ActiveInteraction::Extras::RunCallback

  after_run do
    # LogAttempt.log
  end

  after_successful_run do
    # Email.deliver
  end

  after_failed_run do
    # NotifyAdminEmail.deliver
  end

  def execute
  end
end

StrongParams

class UpdateUserForm < ActiveInteraction::Base
  include ActiveInteraction::Extras::StrongParams

  string :first_name, default: nil, permit: true
  string :last_name, default: nil

  def execute
    first_name # => 'Allowed'
    last_name  # => nil
  end
end

UpdateUserForm.new.to_model.model_name.param_key # => 'update_user_form'

form_params = ActionController::Parameters.new(
  update_user_form: {
    first_name: 'Allowed',
    last_name: 'Not allowed',
  },
)

Service.run(params: form_params)

# OR
form_params = ActionController::Parameters.new(
  first_name: 'Allowed',
  last_name: 'Not allowed',
)

Service.run(form_params: form_params)

Transaction

class UpdateUserForm < ActiveInteraction::Base
  include ActiveInteraction::Extras::Transaction

  run_in_transaction!

  def execute
    Comment.create! # succeeds

    errors.add(:base, :invalid)
  end
end

UpdateUserForm.run
Comment.count # => 0

Jobs

You no longer need to create a separate Job class for the each interaction. This Job extension automatically converts interactions to background jobs. By convention each interaction will have a nested Job class which will be inherited from the parent interaction Job class (e.g. ApplicationInteraction::Job).

ActiveJob

class ApplicationInteraction < ActiveInteraction::Base
  include ActiveInteraction::Extras::ActiveJob

  class Job < ActiveJob::Base
    include ActiveInteraction::Extras::ActiveJob::Perform
  end
end

class DoubleService < ApplicationInteraction
  integer :x

  def execute
    x + x
  end
end

DoubleService.delay.run(x: 2) # queues to run in background
DoubleService.delay(queue: 'low_priority', wait: 1.minute).run(x: 2)

In ActiveJob mode delay method accepts anything ActiveJob set method does. (wait, wait_until, queue, priority)

Sidekiq

You can use sidekiq directly if you need more control. Sidekiq integration comes with default GlobalID support.

class ApplicationInteraction < ActiveInteraction::Base
  include ActiveInteraction::Extras::Sidekiq

  class Job
    include Sidekiq::Worker
    include ActiveInteraction::Extras::Sidekiq::Perform
  end
end

class DoubleService < ApplicationInteraction
  job do
    sidekiq_options retry: 1 # configure sidekiq options
  end

  integer :x

  def execute
    x + x
  end
end

DoubleService.delay.run(x: 2) # queues to run in background
DoubleService.delay(queue: 'low_priority', wait: 1.minute).run(x: 2)

In Sidekiq mode delay method accepts anything sidekiq set method does (queue, retry, backtrace, etc). Plus two additional wait and wait_until.

# Advance usage: retry based on given params
class DoubleService < ApplicationInteraction
  job do
    sidekiq_options(retry: ->(job) {
      params = deserialize_active_job_args(job)
      params[:x]
    })
  end

  integer :x

  def execute
    x + x
  end
end
# Advance usage: Rescue the job but not service
class DoubleService < ApplicationInteraction
  job do
    def perform(*args)
      super
    rescue StandardError => e
      params = deserialize_active_job_args(args)
      params[:x]
    end
  end

  integer :x

  def execute
    raise
  end
end

DoubleService.run # => RuntimeError
DoubleService.delay.perform_now(x: 2) # => returns 2

Rspec

class SomeService < ActiveInteraction::Base
  integer :x
end

RSpec.describe SomeService do
  include ActiveInteraction::Extras::Rspec

  it 'works' do
    expect_to_execute(SomeService,
      with: [{ x: 1 }]
      return: :asd
    )

    result = SomeService.run! x: 1

    expect(result).to eq :asd
  end

  it 'lists all mocks' do
    # allow_to_run
    # allow_to_execute
    # allow_to_delay_run
    # allow_to_delay_execute

    # expect_to_run / expect_not_to_run / expect_to_not_run
    # expect_to_execute
    # expect_to_delay_run / expect_not_to_run_delayed / expect_to_not_run_delayed
    # expect_to_delay_execute
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
