Ruby on Rails-Ruby on Rails web apps

Example

Using the `rails generate scaffold Post title:string body:text` command

Scenario

In a blog application, scaffolding can generate the model, views, and controller for a 'Post' resource. This command creates all the necessary files and boilerplate code to start managing posts in the application, significantly speeding up development time.

Example

Defining a model with `class Post < ApplicationRecord`

Scenario

Active Record is the ORM layer in Rails. It maps database tables to Ruby classes, allowing developers to interact with the database using Ruby code. For instance, in a forum application, creating, reading, updating, and deleting user posts can be done through the Post model, abstracting away direct SQL queries.

Example

Defining routes with `resources :posts` in `config/routes.rb`

Scenario

Routing in Rails is used to connect incoming requests to the appropriate controller actions. In an e-commerce application, routes can be defined to handle various actions like viewing products, adding items to a cart, and checking out, ensuring that the correct controller and action are called for each URL.
