In section 13.3 of our e-book course, we'll cover creating a Django project and configuring the database. Django is a high-level web development framework written in Python that promotes rapid development of web applications, with a clean and pragmatic design.
To start creating a Django project, you need to install Django in your development environment. If you already have Python installed, you can install Django using the pip package manager with the command 'pip install Django'. Once Django is installed, you can create a new Django project using the 'django-admin startproject [project name]' command. This will create a new directory named after your project that contains the basic structure of a Django project.
Once you've created a new Django project, the next step is to configure the database. Django comes with an abstract database system that lets you work with almost any database you can imagine. The default database for Django projects is SQLite, but you can also use other databases like PostgreSQL, MySQL or Oracle.
To configure the database, you will need to modify the 'settings.py' file in your Django project. This file contains all the settings for your Django project, including database settings. The database configuration section in this file is named 'DATABASES'. Here you will specify the database engine, database name, user, password and host.
For example, if you are using PostgreSQL, your database configuration might look like this:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'mydatabase',
'USER': 'mydatabaseuser',
'PASSWORD': 'mypassword',
'HOST': 'localhost',
'PORT': '5432',
}
}
After setting up the database, you can create the database tables using the 'python manage.py migrate' command. This command creates database tables based on your Django models.
It's important to note that Django comes with a built-in database migrations system. Whenever you make changes to your models, you can use the 'python manage.py makemigrations' command to create migrations that change the database schema. You can then apply these migrations using the 'python manage.py migrate' command.
In summary, creating a Django project and configuring the database is a simple but crucial process for developing web applications with Django. We hope that this chapter of our ebook course has given you a clear understanding of how to create a Django project and configure the database. In the next chapter, we'll explore more about creating views and templates in Django.
