## Resource

In this lesson, you’ll learn about: Ruby on Rails internals and how its integrated components process a web request from start to response1. Rails as a “Framework of Frameworks”Ruby on Rails is built as a collection of tightly integrated components: Routing system Controllers ORM (database layer) View rendering engine Asset management 🔹 Key Idea Rails combines multiple subsystems into one unified development ecosystem2. Request Lifecycle (High-Level Flow)User request → Router → Controller → Model → View → Response👉 Key Insight Every web request travels through a structured pipeline inside Rails3. Action Pack & Routing (Entry Point)🔹 What it does Handles incoming HTTP requests🔹 Key components: Router → maps URL to controller action Controllers → process request logic 🔹 RESTful routing: Standard URL patterns for resources Example: /posts → index /posts/1 → show 👉 Key Insight Routing connects the outside world to internal application logic4. Controllers (Application Logic Layer)🔹 Responsibilities: Receive requests Interact with models Prepare data for views 🔹 Data passing: Uses instance variables (e.g., @user) 👉 Key Insight Controllers act as the decision-making layer in MVC5. Active Record (ORM & Data Layer)🔹 What it is Rails’ built-in ORM system🔹 Core functions: Maps Ruby objects to database tables Handles CRUD operations automatically 🔹 Key FeaturesDatabase Migrations Version-controlled schema changes Validations Ensure data integrity before saving Callbacks Trigger logic during lifecycle events (create, update, delete) 👉 Key Insight Active Record eliminates the need to write raw SQL in most cases6. Models (Business Logic + Data Rules)🔹 What models do: Represent database entities Enforce rules and relationships 👉 Key Insight Models combine data + logic into a s…
