ruby
module ApplicationService
  class Base < Servactory::Base
    configuration do
      input_error_class ApplicationService::Errors::InputError

      internal_error_class ApplicationService::Errors::InternalError

      failure_class ApplicationService::Errors::Failure
    end
  end
end
ruby
module ApplicationService
  module Errors
    class InputError < Servactory::Errors::InputError; end
    class OutputError < Servactory::Errors::OutputError; end
    class InternalError < Servactory::Errors::InternalError; end

    class Failure < Servactory::Errors::Failure; end
  end
end

Collection mode ​

ruby
module ApplicationService
  class Base < Servactory::Base
    configuration do
      collection_mode_class_names([ActiveRecord::Relation])
    end
  end
end

Hash mode ​

ruby
module ApplicationService
  class Base < Servactory::Base
    configuration do
      hash_mode_class_names([CustomHash])
    end
  end
end

Helpers for input ​

Custom helpers for input are based on the must and prepare options.

Example with must ​

ruby
module ApplicationService
  class Base < Servactory::Base
    configuration do
      input_option_helpers(
        [
          Servactory::Inputs::OptionHelper.new(
            name: :must_be_6_characters,
            equivalent: {
              must: {
                be_6_characters: {
                  is: ->(value:) { value.all? { |id| id.size == 6 } },
                  message: lambda do |input:, **|
                    "Wrong IDs in `#{input.name}`"
                  end
                }
              }
            }
          )
        ]
      )
    end
  end
end

Example with prepare ​

ruby
module ApplicationService
  class Base < Servactory::Base
    configuration do
      input_option_helpers(
        [
          Servactory::Inputs::OptionHelper.new(
            name: :to_money,
            equivalent: {
              prepare: ->(value:) { Money.from_cents(value, :USD) }
            }
          )
        ]
      )
    end
  end
end
