Creating a model

To create a new model, inherit from the built in Model class and then define any attributes with a field type. For example, here is a book model:

# models.py

from django.db import models


class Book(models.Model):
	title = models.CharField(max_length=200)
	author = models.CharField(max_length=200)
	price - models.DecimalField(max_digits=6, decimal_places=2)
	
	def __str__(self):
		return self.title
		

A model represents a table in a database. The above model represents a Book table, with the columns title, author and price, as well as some implicit columns such as id.

The __str__ method decides what will be shown on the console when print is used on an instance of the model, as well as what shows in the Django admin.
