collectiveidea/awesome_nested_set

This system is the Awesome Nested Set gem, a Ruby library that manages hierarchical tree structures within ActiveRecord models using the nested set pattern. It provides core capabilities for creating, moving, pruning, and validating nodes in a tree hierarchy, ensuring data integrity through transactional operations and retry logic for database conflicts. The library is designed for broad compatibility, supporting Rails versions from 5.2 to 8.1 and multiple database adapters including PostgreSQL, MySQL, and Oracle.

7 changes.

The project modernized its gem infrastructure to support Rails 8.1, replacing legacy Rake and Test::Unit tasks with Bundler and RSpec 3. It refactored the library into a modular structure, removed obsolete view helpers, and significantly expanded the test suite to cover multiple database adapters and edge cases.

4 changes.

This period focused on updating the Awesome Nested Set library to version 3.9.0 to address ordering issues and ensure compatibility with newer Rails versions. The work also involved establishing the project's gemspec and development dependencies, alongside expanding test coverage by adding support models and verifying the nested\_set\_options helper.

4 changes.

The nested set model logic was refactored into distinct behavioral modules to improve maintainability and align deletion and movement operations with Rails standards. Comprehensive test coverage was added for hierarchical operations and transaction retry logic to ensure reliability. Support was expanded to include testing across a wide range of Rails versions from 5.2 to 8.1.

The unused \awesome\_nested\_set\_tasks.rake\ file has been deleted from the project, cleaning up the task directory.

The gem now supports Rails 8.1, extending compatibility to the latest framework versions (up to 8.1.0) alongside Rails 7.2, 7.1, 7.0, 6.1, 6.0, and 5.2. To facilitate testing across these versions, the project has adopted the Appraisals tool, which defines specific Gemfiles for each supported Rails version and includes necessary dependencies for Rails 7.0. The build and release infrastructure has been updated to use Bundler for gem helper tasks and RSpec for testing, replacing the previous Rake-based test and RDoc generation tasks. Additionally, legacy Rails plugin hooks (init.rb, install.rb, uninstall.rb) have been removed, and the project now uses a standard Gemfile.lock ignore pattern in .gitignore.

The nested set model logic has been reorganized into distinct modules (Movable, Prunable, Rebuildable, Relatable, Transactable, Validatable) to improve code clarity and maintainability. This refactoring introduces specific behavioral changes: moving nodes now supports \:root\ as a target for \move\_to\_child\_of\, and \move\_to\_child\_with\_index\ now correctly handles moving nodes to specific positions within a sibling list. Deletion behavior for \dependent: :restrict\_with\_error\ and \dependent: :restrict\_with\_exception\ has been aligned with Rails standards, ensuring proper error handling and transaction abortion. Additionally, the \scope\_for\_rebuild\ method now correctly handles NULL values in scope columns using SQL \IS NULL\ comparisons, and the \rebuild!\ process maintains consistent ordering by primary key.

The \awesome\_nested\_set\_helper.rb\ file, which provided view helpers like \nested\_set\_options\_for\_select\ for generating select options from nested set trees, has been removed. The main library file (\awesome\_nested\_set.rb\) has been refactored to use a modular structure, requiring \awesome\_nested\_set/awesome\_nested\_set\ and utilizing \ActiveSupport.on\_load\ for injection, replacing the previous inline module definitions. This change removes the automatic inclusion of view helpers in all views and updates the internal architecture to align with modern Rails patterns.

Added test coverage for User model hierarchical operations; Added test fixtures for nested set models and behaviors; Added test support models for nested set scenarios; Added tests for the nested\_set\_options helper; Added tests for transaction retry logic; Expanded test database schema and configuration for comprehensive coverage; Migrate test suite from RSpec 2 to RSpec 3 and modernize test infrastructure; Removed placeholder unit test file.

The awesome\_nested\_set gem has been updated to version 3.9.0. This release includes various fixes and improvements to the nested set functionality, such as handling nil left/right values, fixing ordering issues, and ensuring compatibility with newer Rails versions. The library continues to provide efficient tree structure management for ActiveRecord models.

The gemfiles directory now includes dedicated Appraisal configurations for Rails 5.2, 6.0, 6.1, 7.0, 7.1, 7.2, 8.0, and 8.1, enabling the library to be tested and used across these specific framework versions. The Rails 7.0 gemfile explicitly adds dependencies for base64, bigdecimal, drb, and mutex\_m, while the other versions rely on the gemspec for core dependencies and specify compatible database adapters (sqlite3, mysql2, pg).

gemfiles · high confidence

The project introduces its primary gemspec and Gemfile, defining the library as 'awesome\_nested\_set' with a runtime dependency on ActiveRecord versions 4.0.0 through 8.1.x. Development dependencies are established for testing and appraisal, including rspec-rails (4.0.0 to \<8.0), database\_cleaner, and rake (\~\> 13), while specifying a minimum Ruby version of 2.0.0.
