The contrib packages

The contrib packages are a part of Django that contain some very useful

applications that the Django developers decided should be shipped with Django.

The included applications provide an impressive set of features, including some that

we'll be using in this application:

• Admin is a full featured CMS that can be used to manage the content of a

Django site. The Admin application is an important reason for the popularity

of Django. We'll use this to provide an interface for site administrators to

moderate and manage the data in our application

• Auth provides user registration and authentication without requiring us to

do any work. We'll be using this module to allow users to sign up, sign in,

and manage their profiles in our application

There are a lot more goodies in the contrib module. I suggest you

take a look at the complete list at https://docs.djangoproject.

com/en/stable/ref/contrib/#contrib-packages.

I usually end up using at least three of the contrib packages in all

my Django projects. They provide often-required features like user

registration and management, and free you to work on the core parts

of your project, providing a solid foundation to build upon.

Setting up our development environment

For this rst chapter, I'll go into some details about setting up the development

environment. For later chapters, I'll only be providing minimal instructions. For

further details about how I setup the development environment and why, take a look

at Appendix, Development Environment Setup Details and Debugging Techniques.

Let's start by creating the directory structure for our project, setting up the virtual

environment and conguring some base Django settings that need to be set up in

every project. Let's call our blogging platform BlueBlog.

Detailed explanations of the steps you're about to see are given

in Appendix, Development Environment Setup Details and Debugging

Techniques. Please refer to that if you're unsure about why we're

doing something or what a particular command does.
