One of the first things I usually do when I start a new project is to initialize the database and then create a superuser so I can log in to the Django admin interface.
To create a new superuser, you open up the command line and go to the root of your Django project. You only need to run one command.
$ python manage.py createsuperuser
You need to fill in information like username, e-mail and a password. Always use a really secure password for you superuser!
When you're finished filling in the information, the superuser is created. You can now start the development server and go to http://127.0.0.1:8000/admin/ and sign in with the user you just created.
