A RuboCop extension that enforces Rails best practices and coding conventions through automated linting.
RuboCop Rails is a plugin for the RuboCop static code analyzer that adds Rails-specific linting rules. It automatically checks Ruby on Rails code against the community Rails Style Guide and other best practices, identifying issues related to ActiveRecord, controllers, migrations, and more. It helps developers write consistent, idiomatic Rails code and catch potential problems early.
Ruby on Rails developers and teams who want to enforce coding standards and best practices across their codebase. It's particularly valuable for projects with multiple contributors or those aiming to maintain high code quality and consistency.
Developers choose RuboCop Rails because it provides a curated, authoritative set of Rails-specific linting rules that go beyond generic Ruby checks. Its deep integration with RuboCop allows for seamless adoption, autocorrection capabilities, and version-aware checking that adapts to different Rails releases.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Enforces comprehensive linting for ActiveRecord, controllers, migrations, and views based on the Rails Style Guide, automating community standards to reduce manual review burden.
TargetRailsVersion configuration adapts checks to specific Rails versions from 4.2+, preventing false positives for deprecated patterns and ensuring compatibility.
Supports automatic violation fixing and integrates with Rails generators via development.rb settings, immediately linting new code as shown in the README's configuration tip.
MigratedSchemaVersion setting excludes already-applied migrations from inspection, focusing linting on current changes without historical file noise.
Requires RuboCop 1.72+ for the plugin system; older projects must use the deprecated require method, complicating updates and setup consistency.
The recommended autocorrection with rubocop -A is labeled unsafe in the README and may introduce bugs in non-generated or complex code, necessitating manual oversight.
Multiple setup methods (config file, command line, rake task) and per-cop tuning in .rubocop.yml can be overwhelming, especially when combining with other RuboCop extensions.
