UUIDField - Django Models - GeeksforGeeks

Last Updated : 12 Jul, 2025

UUIDField is a special field to store

. It uses Python's

class. UUID, Universal Unique Identifier, is a python library that helps in generating random objects of 128 bits as ids. It provides the uniqueness as it generates ids on the basis of time, Computer hardware (MAC etc.). Universally unique identifiers are a good alternative to AutoField for

. The database will not generate the UUID for you, so it is recommended to use

. For example,

import uuid
from django.db import models

class MyUUIDModel(models.Model):
    id = models.UUIDField(
         primary_key = True,
         default = uuid.uuid4,
         editable = False)
    # other fields

field_name = models.UUIDField(**options)

Illustration of UUIDField using an Example. Consider a project named

having an app named

.

Refer to the following articles to check how to create a project and an app in Django.

• How to Create a Basic Project using MVT in Django?
• How to Create an App in Django ?

Enter the following code into

file of

app.

from django.db import models
from django.db.models import Model
# Create your models here.

class GeeksModel(Model):
    geeks_field = models.UUIDField()

Add the geeks app to

# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'geeks',
]

Now when we run

command from the terminal,

Python manage.py makemigrations

A new folder named migrations would be created in

directory with a file named

# Generated by Django 2.2.5 on 2019-09-25 06:00

from django.db import migrations, models

class Migration(migrations.Migration):

    initial = True

    dependencies = [
    ]

    operations = [
        migrations.CreateModel(
            name ='GeeksModel',
            fields =[
                ('id', 
                  models.AutoField(auto_created = True,
                  primary_key = True,
                  serialize = False, 
                  verbose_name ='ID'
                )),
                ('geeks_field', 
                  models.UUIDField()
                 )),
            ],
        ),
    ]

Thus, an

is created when you run makemigrations on the project.It is a field to store python's UUID instance.

UUID, Universal Unique Identifier, is a python library which helps in generating random objects of 128 bits as ids. To know more about UUID visit

. Let's try to save a uuid object into the UUIDField.

# importing the model
# from geeks app
from geeks.models import GeeksModel

# importing uuid
import uuid

# creating an instance of
# uuid object
test = uuid.uuid4()

# creating a instance of 
# GeeksModel
geek_object = GeeksModel.objects.create(geeks_field = test)
geek_object.save()

Now let's check it in admin server. We have created an instance of GeeksModel

Field Options are the arguments given to each field for applying some constraint or imparting a particular characteristic to a particular Field. For example, adding an argument

to UUIDField will enable it to store empty values for that table in relational database. Here are the option and attributes that an UUIDField can use.
