Django admin page doesn't show tables of database (djangobook chapter 06)

I am doing the Activating the Admin Interface part in djangobook chapter 06. At the end of that part one has to run the development server and go to http://127.0.0.1:8000/admin/.

However I see this:

Instead of something like this(from the djangobook):

This is strange because I have data stored in a table of my mysql database that is linked to my django project in the settings.py file.

This is the DATABASES dictionary in my settings.py file of my django project:

DATABASES = {
    'default': {
        'ENGINE': 'mysql',
        'NAME': 'mydb',                   
        'USER': 'root',                      
        'PASSWORD': 'mypass',                 
        'HOST': 'localhost',                    
        'PORT': '',                      
    }
}

The mysql prompt shows this:

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| mydb               |
+--------------------+
3 rows in set (0.00 sec)

mysql> use mydb;
mysql> show tables;
+----------------------------+
| Tables_in_mydb             |
+----------------------------+
| auth_group                 |
| auth_group_permissions     |
| auth_message               |
| auth_permission            |
| auth_user                  |
| auth_user_groups           |
| auth_user_user_permissions |
| books_author               |
| books_book                 |
| books_book_authors         |
| books_publisher            |
| django_admin_log           |
| django_content_type        |
| django_session             |
+----------------------------+
14 rows in set (0.00 sec)

Why am I not seeing the contents of mydb in my admin page?

Might be relevant:

mysql> select User from mysql.user;
+------------------+
| User             |
+------------------+
| root             |
| debian-sys-maint |
| root             |
| root             |
+------------------+
4 rows in set (0.00 sec)

You need to keep reading http://django-book.readthedocs.org/en/latest/chapter06.html#adding-your-models-to-the-admin-site

There’s one crucial part we haven’t done yet...
Within the books directory (mysite/books), create a file called admin.py, and type in the following lines of code:

from django.contrib import admin
from mysite.books.models import Publisher, Author, Book

admin.site.register(Publisher)
admin.site.register(Author)
admin.site.register(Book)
