What are Django models and how do I use them?

Django models are Python classes that define the structure of your database. They allow you to create, retrieve, update, and delete records in your database using Python code.

Can you show me a simple example of a Django model?

Sure! Here's a basic example:

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    published_date = models.DateField()

This defines a Book model with three fields.

How do I create a database table from this model?

You can create a database table by running the command python manage.py makemigrations followed by python manage.py migrate in your terminal.

What if I want to add more fields to my model?

You can simply add more attributes to your model class and then run the migration commands again to update the database.
