Module: Plutonium::Interaction::Concerns::WorkflowDSL

Extended by:
ActiveSupport::Concern
Defined in:
lib/plutonium/interaction/concerns/workflow_dsl.rb

Overview

DO NOT USE

Provides a Domain Specific Language (DSL) for defining workflows in interactions.

This module allows interactions to define a series of steps that can be executed in sequence, with optional conditions for each step.

Examples:

class MyWorkflow < Plutonium::Interaction::Base
  include Plutonium::Interaction::Concerns::WorkflowDSL

  workflow do
    step :validate_input, ValidateInputInteraction
    step :process_data, ProcessDataInteraction, if: ->(ctx) { ctx[:data_valid] }
    step :send_notification, SendNotificationInteraction
  end

  private

  def execute
    execute_workflow(attributes.to_h)
  end
end

Defined Under Namespace

Classes: WorkflowBuilder
