rails-generators

Rails generators use Thor to define custom scaffolding logic. Create a generator class inheriting from Rails::Generators::Base, set source_root to your templates directory, define public methods to render ERB templates, and invoke the generator with `rails generate your_generator_name`. This automates boilerplate for models, controllers, migrations, and tests.

Yes. Define options using `class_option` to accept runtime parameters, create ERB templates in your templates folder, and use `template` and `create_file` methods to render them. This lets you generate namespaced features, API patterns, and full-stack code that follows your architectural standards.

Generators support hook-based composition for test frameworks. Define conditional template rendering based on test framework detection, invoke generator hooks at key points, and provide framework-specific templates. This ensures generated code includes appropriate test setup for your chosen testing tool.

Production-ready generators support Rails 8 conventions and can generate services, models, controllers, and API endpoints. Define generator methods to scaffold services with proper namespacing, create corresponding templates for business logic, and ensure migrations and tests are generated alongside.

Organize generators in lib/generators using namespace directories that match your feature structure. Define source_root per generator, use nested class names to create hierarchical generator commands, and support option flags for customization. This enables consistent, composable feature generation across your Rails project.

Yes. Generators execute multiple public methods in sequence to create models, migrations, tests, and documentation files from templates. Use `invoke` to call other generators, chain `template` calls, and conditionally create files based on options, producing complete feature scaffolding in one command.
