Introduction

Creating a new Rails project sets up all the files and folders you need to start building a web app quickly.

When you want to start a brand new web application using Rails.

When you need a ready-made structure with default settings for your app.

When you want to quickly generate a project with specific options like database choice.

When you want to experiment with Rails features in a fresh environment.

Syntax

Ruby on Rails

rails new project_name [options]

project_name is the folder and app name you choose.

You can add options like --database=postgresql to pick your database.

Examples

Sample Program

This command creates a new Rails project called sample_app using SQLite3 as the database. It sets up all folders, files, and default configurations so you can start coding your app immediately.

Ruby on Rails

rails new sample_app --database=sqlite3

Important Notes

You need Ruby and Rails installed before running rails new.

The command creates a folder with your project name and fills it with files.

You can add many options to customize your new app, like skipping tests or choosing a different JavaScript setup.

Summary

rails new quickly sets up a new Rails app with all needed files.

You choose the app name and can add options for database and features.

After running it, you get a ready-to-use project folder to start coding.
