How does this skill help with testing?

The skill provides standardized RSpec patterns to verify that transitions work as expected, ensure guards block invalid moves, and confirm that callbacks trigger correctly.

What happens if a transition fails?

The skill demonstrates how to use both 'soft' transitions that return false and 'bang' methods (e.g., event!) that raise AASM::InvalidTransition for robust error handling.

Can I use guards to prevent certain transitions?

Yes, AASM Coder implements guards which are methods or blocks that must return true for a transition to occur, providing a safety layer for business rules.

What is the primary benefit of using AASM in Rails?

AASM provides a clean, declarative DSL to manage the various states of an object, preventing invalid state transitions and centralizing business logic.

Does it support multiple state machines on one model?

Yes, it can configure AASM to use specific columns, allowing for multiple independent state machines within a single ActiveRecord model.

開発者ツール

Implements robust state machines and workflow management in Ruby on Rails using the AASM gem.

概要

The AASM Coder skill streamlines the implementation of finite state machines within Ruby on Rails applications. It provides expert guidance on defining states, events, and transitions, ensuring that complex business logic remains organized and maintainable. By leveraging this skill, developers can easily incorporate advanced features such as conditional guards, lifecycle callbacks, and comprehensive RSpec testing patterns, making it an essential tool for managing object lifecycles in order processing, publishing workflows, or user onboarding systems.
