Django Tutorial: User Registration 🎯

Welcome to our comprehensive Django User Registration tutorial! In this lesson, we'll dive deep into creating a user registration system using Django. We'll cover everything from setting up a project, creating a registration form, handling user creation, and even a small quiz to test your understanding. Let's get started!

What is Django? 📝

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It's built by experienced developers and takes care of much of the hassle of web development, so you can focus on writing your app without needing to reinvent the wheel.

Setting Up the Project 📝

First, make sure you have Python and Django installed. If not, you can find the installation instructions here.

Once installed, create a new Django project:

bash

django-admin startproject mysite
cd mysite

Creating the Registration App 📝

Now, let's create a new app called registration.

bash

python manage.py startapp registration

User Models 📝

Django comes with a built-in User model that handles user authentication. We'll use this model to manage our users.

python

# registration/models.py
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager

class CustomUserManager(BaseUserManager):
    pass

class CustomUser(AbstractBaseUser):
    email = models.EmailField(_('email address'), unique=True)
    is_active = models.BooleanField(_('active'), default=True)
    is_staff = models.BooleanField(_('staff status'), default=False)
    date_joined = models.DateTimeField(_('date joined'), default=timezone.now)

    objects = CustomUserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']

Creating the Registration Form 📝

Next, we'll create a registration form. This form will be used to gather user information during the registration process.

python

# registration/forms.py
from django import forms
from django.contrib.auth.forms import UserCreationForm
from .models import CustomUser

class CustomUserCreationForm(UserCreationForm):
    email = forms.EmailField(required=True)

    class Meta:
        model = CustomUser
        fields = ('username', 'email', 'password1', 'password2')

Migrating the Database ✅

Now, let's migrate our database to create the new CustomUser table.

bash

python manage.py makemigrations
python manage.py migrate

Creating the Registration View 📝

Next, we'll create a view to handle the registration process.

python

# registration/views.py
from django.shortcuts import render, redirect
from django.contrib.auth import login, authenticate
from django.contrib.auth.forms import LoginForm
from .forms import CustomUserCreationForm
from django.contrib.auth.decorators import login_required

def register(request):
    if request.method == 'POST':
        form = CustomUserCreationForm(request.POST)
        if form.is_valid():
            user = form.save()
            login(request, user)
            return redirect('home')
    else:
        form = CustomUserCreationForm()

    return render(request, 'registration/register.html', {'form': form})

@login_required
def user_login(request):
    if request.method == 'POST':
        form = LoginForm(data=request.POST)
        if form.is_valid():
            user = authenticate(request, username=form.cleaned_data.get('username'), password=form.cleaned_data.get('password'))
            if user is not None:
                login(request, user)
                return redirect('home')
    else:
        form = LoginForm()

    return render(request, 'registration/login.html', {'form': form})

Creating Registration Templates 📝

Finally, we'll create the registration and login templates.

bash

touch registration/templates/registration/register.html
touch registration/templates/registration/login.html

Testing the Registration System ✅

Now, let's test our registration system.

Run the development server: python manage.py runserver
Open a web browser and navigate to http://127.0.0.1:8000/accounts/register/
Fill out the registration form and click "Register"
Open the login page (http://127.0.0.1:8000/accounts/login/) and use the registered email and password to log in
