Django Tutorial: Creating Users 🎯

Welcome to the Django Tutorial! Today, we'll learn how to create users in Django, a powerful Python web framework. By the end of this tutorial, you'll understand how to create, manage, and authenticate users in your Django projects. Let's dive in! 🌊

Understanding User Authentication in Django 📝

Django provides an integrated user authentication system, making it easier for you to manage user accounts and their permissions. When we create a new Django project, it comes with a pre-built auth app that contains models for handling users and groups.

Setting Up the Project ✅

To get started, let's create a new Django project:

bash

django-admin startproject myproject
cd myproject

Now, let's create a new app named accounts:

bash

python manage.py startapp accounts

Creating the User Model 💡

Django uses the AbstractUser model in its auth app, which includes fields for username, email, first name, last name, and password. We can create a custom user model by extending the AbstractUser in our accounts app.

Open accounts/models.py and modify the file as follows:

python

from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    pass

Now, let's register our custom user model in our project settings:

Open myproject/settings.py and find the AUTH_USER_MODEL setting. Set it to our custom user model:

python

AUTH_USER_MODEL = 'accounts.CustomUser'

Registering the User Model 📝

To allow Django to manage our custom user model, we need to register it. Open accounts/admin.py and modify the file as follows:

python

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import Group, User
from .models import CustomUser

class CustomUserAdmin(UserAdmin):
    model = CustomUser

admin.site.unregistered_model(User)
admin.site.unregistered_model(Group)

admin.site.register(CustomUser, CustomUserAdmin)

Now, when you run the Django admin site, you should be able to create and manage users using our custom user model.

Creating Users Programmatically 💡

Let's create a function to create a new user programmatically. Open accounts/models.py and add the following code:

python

from django.contrib.auth import get_user_model
from django.contrib.auth.password_validation import validate_password

def create_user(username, email, password, **extra_fields):
    user = get_user_model().objects.create_user(
        username=username,
        email=email,
        password=password,
        **extra_fields
    )

    user.save(using=None, keep_passhash=False)
    user.set_password(password)
    user.save()

    return user

Here, we create a create_user function that takes the username, email, and password as arguments, along with any additional fields you might want to set for the user.

Creating Users in the Django Shell ✅

Let's test our create_user function in the Django shell:

bash

python manage.py shell

Now you can create a new user:

python

from accounts.models import create_user

user = create_user('myusername', 'myemail@example.com', 'mypassword')
print(user)
