How to create a database

Creating a database in Ruby on Rails is a relatively straightforward process. Here are the basic steps:

Generate a new Rails application by running the following command in your terminal:

rails new myapp

This will create a new Rails application in a directory called myapp.

Navigate to the newly created directory by running the following command:

cd myapp

Open the config/database.yml file in a text editor. This file contains the database configuration settings for your application. By default, Rails uses SQLite as its database management system, but you can change this by updating the settings in this file.

Create the database by running the following command:

rails db:create

This will create a new database for your application.

Run any migrations that need to be executed by running the following command:

rails db:migrate

This will create the necessary database tables and columns for your application.

Verify that the database has been created by running the following command:

rails dbconsole

This will open a console where you can interact with your database. You can enter SQL commands here to query the database or insert data.
