RubyMine

RubyMine provides specialized tooling for Ruby and Rails. It excels at navigating the "Magic" of Rails (views to controllers, routes to actions).

When to Use

• Ruby on Rails: It connects the dots that text editors miss.
• RSpec / Cucumber: Visual test runner and step definition navigation.
• Debugging: ruby-debug-ide integration is seamless.

Core Concepts

Rails Project View

Groups Models, Views, and Controllers logically.

ERB / Slim / Haml

Full support for template languages.

Gem Management

GUI for Gemfile and bundle install.

Best Practices (2025)

Do:

• Use "Go to Route": Search standard Rails routes and jump to controller actions.
• Use RuboCop: Integrated linter.
• Model Dependency Diagram: Visualize your ActiveRecord associations (has_many, belongs_to).

Don't:

• Don't guess functionality: Ctrl+Click method names to see where they are defined (even metaprogrammed ones sometimes).
