IntegerField

An IntegerField is a Django model field that represents a non-negative integer. It is a subclass of the IntegerField class in Django's core fields module.

An IntegerField can be used to store whole numbers, such as a person's age or the number of items in a shopping cart. It can also be used to represent IDs or other unique identifiers that are integers.

In a Django model, an IntegerField can be defined with various optional arguments, such as default values, maximum and minimum values, and whether the field is required or not. For example:

from django.db import models

class Person(models.Model):
    age = models.IntegerField(default=18, null=True, blank=True)

In this example, the age field is an IntegerField with a default value of 18. It can be null (i.e., have no value) and blank (i.e., not required to be filled in).
