Object- Relational Mapper

Django has its own object relational mapper which eases database access. It facilitates writing of model classes directly in python. Model classes can be defined by sub-classing django.db.models.Model. Each attribute of this class corresponds to a database field. This makes it possible to use an automatically generated database access API.

from django.db import models

class Person(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)

The database columns first_name and last_name are specified as class attributes and an id field is automatically added to the table.

Automatic admin interface

Generating admin sites for the staff to add,change or delete content is made easy by Django by automating the creation of admin interfaces for models. Creating an admin user is as easy as follows:

1. Create a user

$ python manage.py createsuperuser

2. Enter the username

Username: admin

3. Enter email address

Email address: admin@example.com

4. Final step is to setup a password as follows and the admin site gets created and is activated by default.

Password: **********
Password (again): *********
Superuser created successfully
