Overview

Welcome to `::Rails`

What's Rails?

::Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.

Understanding the MVC pattern is key to understanding ::Rails. MVC divides your application into three layers: Model, View, and Controller, each with a specific responsibility.

Model layer

The Model layer represents the domain model (such as Account, Product, Person, Post, etc.) and encapsulates the business logic specific to your application. In Rails, database-backed model classes are derived from ::ActiveRecord::Base. Active Record allows you to present the data from database rows as objects and embellish these data objects with business logic methods. Although most ::Rails models are backed by a database, models can also be ordinary Ruby classes, or Ruby classes that implement a set of interfaces as provided by the Active Model module.

View layer

The View layer is composed of "templates" that are responsible for providing appropriate representations of your application's resources. Templates can come in a variety of formats, but most view templates are HTML with embedded Ruby code (ERB files). Views are typically rendered to generate a controller response or to generate the body of an email. In Rails, View generation is handled by Action View.

Controller layer

The Controller layer is responsible for handling incoming HTTP requests and providing a suitable response. Usually, this means returning HTML, but ::Rails controllers can also generate XML, JSON, PDFs, mobile-specific views, and more. Controllers load and manipulate models, and render view templates in order to generate the appropriate HTTP response. In Rails, incoming requests are routed by Action Dispatch to an appropriate controller, and controller classes are derived from ::ActionController::Base. Action Dispatch and Action Controller are bundled together in Action Pack.

Frameworks and libraries

Active Record, Active Model, Action Pack, and Action View can each be used independently outside ::Rails.

In addition to that, ::Rails also comes with:

Action Mailer, a library to generate and send emails
Action Mailbox, a library to receive emails within a ::Rails application
Active Job, a framework for declaring jobs and making them run on a variety of queuing backends
Action Cable, a framework to integrate WebSockets with a ::Rails application
Active Storage, a library to attach cloud and local files to ::Rails applications
Action Text, a library to handle rich text content
Active Support, a collection of utility classes and standard library extensions that are useful for ::Rails, and may also be used independently outside ::Rails

Getting Started

Install Rails at the command prompt if you haven't yet:
```
$ gem install rails
```
At the command prompt, create a new ::Rails application:
```
$ rails new myapp
```

where "myapp" is the application name.

Change directory to myapp and start the web server:
```
$ cd myapp
$ bin/rails server
```
Run with --help or -h for options.
Go to http://localhost:3000 and you'll see the ::Rails bootscreen with your ::Rails and Ruby versions.
Follow the guidelines to start developing your application. You may find the following resources handy:
