Explain
Rails follows the MVC (Model-View-Controller) architecture for clean separation of concerns.
It includes built-in tools for database migrations, routing, templating, and testing.
Rails promotes convention over configuration, reducing boilerplate code.
Supports RESTful design patterns by default.
Used for rapid development of web applications, APIs, and scalable enterprise platforms.
Core Features
Active Record for database interactions
Action Pack for controllers and views
Action Mailer for sending emails
Routing system for RESTful resources
Built-in support for caching, sessions, and security
Basic Concepts Overview
Models - represent data and business logic
Controllers - handle requests and responses
Views - templates for HTML rendering
Routes - map URLs to controller actions
Migrations - manage database schema changes
Project Structure
app/models - database models
app/controllers - controllers for request handling
app/views - templates for rendering
config/routes.rb - route definitions
db/migrate - database migrations
Building Workflow
Generate Rails app using `rails new`
Define models, controllers, and views
Set up routes and RESTful resources
Run migrations and seed database
Test app and run development server
Difficulty Use Cases
Beginner: static web page with basic CRUD
Intermediate: API with authentication and database
Advanced: E-commerce or SaaS platform
Expert: Scalable enterprise application with microservices
Architect: Integrate Rails with front-end frameworks and background jobs
Comparisons
Rails vs Django: both full-stack, Rails is convention-heavy, Django more explicit
Rails vs Flask: Rails is full-stack, Flask is micro-framework
Rails vs FastAPI: Rails sync-first, full-stack; FastAPI async-first API-focused
Rails vs Express.js: Rails full-stack Ruby framework; Express minimalist Node.js framework
Rails vs Phoenix: Rails uses Ruby, Phoenix uses Elixir and offers concurrency advantages
