ruby-on-rails Skill: Автоматизация разработки приложений

--- name: ruby-on-rails description: >- Comprehensive Ruby on Rails 8.1 best-practices skill covering MVC, Active Record, routing, views, background jobs, storage, security, testing, and performance. Use when the user mentions Rails, Ruby on Rails, ActiveRecord, ActiveJob, ActionMailer, ActionCable, Active Storage, rails generate, rails routes, Hotwire, Turbo, Stimulus, or asks to build, review, debug, or migrate a Rails application or API. --- # Ruby on Rails Best Practices Full-stack Rails 8.1 guide organized as modular rules. Covers MVC core patterns, Active Record, components (jobs, mailer, cable, storage), security, testing, performance, and debugging. ## ROUTING: Which rule file to load **IF working with models, database queries, associations, validations, or migrations:** → Read `rules/core-active-record.md` **IF working with routes, controllers, params, sessions, cookies, or filters:** → Read `rules/core-routing-and-controllers.md` **IF working with views, layouts, partials, ERB templates, or form helpers:** → Read `rules/core-views-and-forms.md` **IF working with background jobs, emails, or WebSocket channels:** → Read `rules/component-jobs-mailer-cable.md` **IF working with file uploads or cloud storage:** → Read `rules/component-active-storage.md` **IF dealing with security concerns (auth, CSRF, XSS, SQL injection, secrets):** → Read `rules/security-best-practices.md` **IF writing or fixing tests:** → Read `rules/testing-patterns.md` **IF optimizing performance or configuring for production:** → Read `rules/perf-caching-and-deployment.md` **IF debugging an error or unexpected behavior:** → Read `rules/debug-tools.md` **IF new to the MVC request cycle or need a top-level orientation:** → Read `rules/core-mvc-request-lifecycle.md` first ## Rule index | Topic | Description | File | |-------|-------------|------| | Sections overview | Categories and reading order | [rules/_sections.md](rules/_sections.md) | | MVC lifecycle | Request pipeline from router to response | [rules/core-mvc-request-lifecycle.md](rules/core-mvc-request-lifecycle.md) | | Active Record | Models, queries, associations, validations, migrations | [rules/core-active-record.md](rules/core-active-record.md) | | Routing & Controllers | RESTful routes, params, callbacks, sessions | [rules/core-routing-and-controllers.md](rules/core-routing-and-controllers.md) | | Views & Forms | ERB, layouts, partials, form helpers | [rules/core-views-and-forms.md](rules/core-views-and-forms.md) | | Jobs / Mailer / Cable | ActiveJob, ActionMailer, ActionCable | [rules/component-jobs-mailer-cable.md](rules/component-jobs-mailer-cable.md) | | Active Storage | File uploads, cloud storage | [rules/component-active-storage.md](rules/component-active-storage.md) | | Security | CSRF, XSS, SQL injection, secrets, auth | [rules/security-best-practices.md](rules/security-best-practices.md) | | Testing | Unit, integration, system tests | [rules/testing-patterns.md](rules/testing-patterns.md) | | Performance & Deploy | Caching strategies, Puma, concurrency | [rules/perf-caching-and-deployment.md](rules/perf-caching-and-deployment.md) | | Debug | byebug, web console, logging, common errors | [rules/debug-tools.md](rules/debug-tools.md) | ## Rule categories by priority | Priority | Category | Impact | Prefix | |----------|----------|--------|--------| | 1 | MVC core patterns | CRITICAL | `core-` | | 2 | Components | HIGH | `component-` | | 3 | Security | HIGH | `security-` | | 4 | Testing | HIGH | `testing-` | | 5 | Performance & Deploy | MEDIUM-HIGH | `perf-` | | 6 | Debug | MEDIUM | `debug-` | ## Coverage and maintenance - Coverage map: `rules/_coverage-map.md` - Source: https://guides.rubyonrails.org/ (Rails 8.1.2) - Update this skill when Rails version changes or when new guides are published. ## Rails CLI quick reference ```bash rails new myapp # new full-stack app rails new myapp --api # API-only mode rails generate model Post title:string body:text rails generate controller Posts index show rails generate migration AddAuthorToPosts author:references rails db:migrate rails db:rollback rails routes # list all routes rails console # interactive REPL rails test # run test suite rails server # start dev server (localhost:3000) ```
