How to add image field in python django model

Typically, each model maps to a single database table.

When creating a Django model then assign every field of the database with its behavior related to the operation of the table with its accessing entities.

from django.db import models

class Product(models.Model):
  ...
  ...
  image = models.ImageField(upload_to=None, height_field=None, width_field=None, max_length=100, **options)
