Django, a high-level Python web framework, provides a default user model that includes common fields like username, email, and password.
However, there are cases where the default user model might not be sufficient for your project's requirements. In such scenarios, creating a custom Django user model becomes essential. This blog post will guide you through the process of creating a custom user model in Django.
There are various reasons why you might want to create a custom user model:
Additional Fields: If you need to store additional information about users, such as their date of birth, profile picture, or any other custom data, a custom user model allows you to include these fields.
Authentication Requirements: If your authentication system requires a different identifier than the default username or email, a custom user model lets you redefine the authentication field.
Integration with Third-Party Apps: Some third-party apps might require additional fields in the user model for proper integration.
If you haven't already, create a new Django project using the following command:
django-admin startproject yourprojectname
Navigate to the project directory:
cd yourprojectname
In your Django app directory, create a file named models.py if it doesn't exist. Open the file and define your custom user model:
# yourapp/models.py from django.contrib.auth.models import AbstractUser from django.db import models class CustomUser(AbstractUser): # Add your custom fields here date_of_birth = models.DateField(null=True, blank=True) profile_picture = models.ImageField(upload_to='profile_pictures/', null=True, blank=True) def __str__(self): return self.username
In this example, the CustomUser model inherits from AbstractUser, which provides the core implementation of the user model.
Open your project's settings.py file and add the following configuration:
# yourprojectname/settings.py AUTH_USER_MODEL = 'yourapp.CustomUser'
Replace 'yourapp' with the actual name of your app.

Run the following commands to create and apply migrations:
python manage.py makemigrations python manage.py migrate
This will create the necessary database tables for your custom user model.
If you want to use Django Admin to manage users, update your admin.py file:
# yourapp/admin.py from django.contrib import admin from django.contrib.auth.admin import UserAdmin from .models import CustomUser admin.site.register(CustomUser, UserAdmin)
Creating a custom Django user model is a crucial step in tailoring your authentication system to the specific needs of your project.
By following the steps outlined in this guide, you can seamlessly integrate a custom user model into your Django application. Whether you need additional fields, a different authentication identifier, or integration with third-party apps, a custom user model provides the flexibility required for a wide range of use cases.
