First, let’s finish our migration,

in terminal,

python manage.py migrate


Now it’s time to create model,

head over to,

models.py and create one,

from django.db import models
 
# Create your models here.
class Product(models.Model):
    product_id = models.AutoField
    product_name = models.CharField(max_length=50)
    desc = models.CharField(max_length=300)
    pub_date = models.DateField()

for reference,

Django


make sure, your app in the setting like this,

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog.apps.BlogConfig',
    'shop.apps.ShopConfig',
]

last 8/9th line


then execute,

python manage.py makemigrations

and finally,

python manage.py migrate
