DHH's style emphasizes clarity over cleverness and convention over configuration. Use seven RESTful controller actions, keep models fat with business logic, place private methods under a private keyword, favor explicit naming, and apply modern Ruby syntax throughout your codebase.

Rails controllers following DHH's approach implement the seven RESTful actions (index, show, new, create, edit, update, destroy) with minimal logic. Move business logic to models, keep controllers thin as routers, and use clear, predictable naming conventions for actions and routes.

Organize private methods by placing them below a private keyword declaration at the end of the class. This signals intent, improves readability, and follows Rails conventions. Group related private methods together and use descriptive names that clarify their purpose.

Fat models hold business logic and domain knowledge directly in the model class. Concerns act as facades for shared, reusable behavior across multiple models. DHH's style favors fat models for clarity, using concerns selectively for truly shared cross-model functionality rather than premature abstraction.

Yes. DHH's style integrates with modern Ruby syntax including keyword arguments, safe navigation operators, and contemporary Rails patterns. The approach values explicit, readable code over syntactic cleverness, adapting naturally as Ruby and Rails evolve.

Refactor Rails code to this style during active feature development, controller rewrites, or model restructuring. Focus on clarity wins first: simplifying controller logic, reorganizing private methods, and improving naming. Avoid wholesale rewrites of working code; apply principles incrementally as you touch each file.
