Extensions Since 2.0.0

You can expand the basic functionality by adding your own extensions.

It is recommended to create extensions in the app/services/application_service/extensions directory. Also, as a recommendation, create extensions in their own directory.

Example of implementation

Connecting

You can add extensions using the with_extensions method.

app/services/application_service/base.rb

require_relative "extensions/status_active/dsl"

module ApplicationService
  class Base
    include Servactory::DSL.with_extensions(
      ApplicationService::Extensions::StatusActive::DSL
    )
  end
end

Extension code

app/services/application_service/extensions/status_active/dsl.rb

module ApplicationService
  module Extensions
    module StatusActive
      module DSL
        def self.included(base)
          base.extend(ClassMethods)
          base.include(InstanceMethods)
        end

        module ClassMethods
          private

          attr_accessor :status_active_model_name

          def status_active!(model_name)
            self.status_active_model_name = model_name
          end
        end

        module InstanceMethods
          private

          def call!(**)
            super

            status_active_model_name = self.class.send(:status_active_model_name)
            return if status_active_model_name.nil?

            is_active = inputs.send(status_active_model_name).active?
            return if is_active

            fail_input!(
              status_active_model_name,
              message: "#{status_active_model_name.to_s.camelize.singularize} is not active"
            )
          end
        end
      end
    end
  end
end

Usage

module PostsService
  class Create < ApplicationService::Base
    input :user, type: User

    make :something
    
    private

    def something
