SlugField - Django Models - GeeksforGeeks

Last Updated : 12 Jul, 2025

A Slug is basically a short label for something, containing only letters, numbers, underscores or hyphens. They’re generally used in URLs. For example, in a typical blog entry URL:

https://www.geeksforgeeks.org/python/add-the-slug-field-inside-django-model/

Here, the last data

is the slug.

SlugField in Django is like a CharField, where you can specify

attribute also. If max_length is not specified, Django will use a default length of 50. It also implies setting

to

.It is often useful to automatically prepopulate a SlugField based on the value of some other value.It uses

or

for validation.

field_name = models.SlugField(max_length=200, **options)

SlugField.max_length

The maximum length (in characters) of the field. The

is enforced at the database level and in Django’s validation using

.

SlugField.allow_unicode

If True, the field accepts Unicode letters in addition to ASCII letters. Defaults to False.

Illustration of SlugField 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.SlugField(max_length = 200)

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.SlugField(
                  max_length = 200,
                )),
            ],
        ),
    ]

Now run,

Python manage.py migrate

Thus, an

is created when you run migrations on the project.

SlugField is used for storing basically storing URL paths after a particular URL. To know more about how to properly add a SlugField to Django Project, refer this article -

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

# creating a instance of 
# GeeksModel
geek_object = GeeksModel.objects.create(geeks_field ="")
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 SlugField will enable it to store empty values for that table in relational database. Here are the field options and attributes that an SlugField can use.
