1. Form: forms.py

# main/forms.py
from django import forms
from django.contrib.auth.forms import UserCreationForm, AuthenticationForm
from django.contrib.auth.models import User

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

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']

2. Views: views.py

# main/views.py
from django.shortcuts import render, redirect
from django.contrib.auth import login, logout, authenticate
from .forms import RegisterForm
from django.contrib.auth.forms import AuthenticationForm

def register_view(request):
    if request.method == 'POST':
        form = RegisterForm(request.POST)
        if form.is_valid():
            user = form.save()
            login(request, user)
            return redirect('home')
    else:
        form = RegisterForm()
    return render(request, 'register.html', {'form': form})

def login_view(request):
    if request.method == 'POST':
        form = AuthenticationForm(data=request.POST)
        if form.is_valid():
            user = form.get_user()
            login(request, user)
            return redirect('home')
    else:
        form = AuthenticationForm()
    return render(request, 'login.html', {'form': form})

def logout_view(request):
    logout(request)
    return redirect('login')

3. URL Routing: urls.py

# main/urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('register/', views.register_view, name='register'),
    path('login/', views.login_view, name='login'),
    path('logout/', views.logout_view, name='logout'),
    path('', views.home_view, name='home'),  # Misal ada halaman home
]

4. Template HTML Sederhana

templates/register.html

<h2>Register</h2>
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Daftar</button>
</form>

templates/login.html

<h2>Login</h2>
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Masuk</button>
</form>

5. Contoh Home View (Opsional)

# main/views.py
from django.contrib.auth.decorators import login_required

@login_required
def home_view(request):
    return render(request, 'home.html')

templates/home.html

<h2>Halo, {{ request.user.username }}!</h2>
<a href="{% url 'logout' %}">Logout</a>
