In this post, we'll learn how to create Django custom 404 and 505 Error pages.

1. Django Project structure


├── core
│   ├── admin.py
│   ├── apps.py
│   ├── forms.py
│   ├── __init__.py
│   ├── migrations
│   ├── models.py
│   ├── __pycache__
│   ├── tests.py
│   ├── urls.py
│   └── views.py
├── db.sqlite3
├── manage.py
├── media
├── pypro
│   ├── __init__.py
│   ├── __pycache__
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── static
└── TEMPLATES


2. Views.py

In our views project, we need to add these two functions.


#core/views.py  

def handler404(request, exception):
    return render(request, 'err/404.html', status=404)

def handler500(request):
    return render(request, 'err/500.html', status=500)


handler404 function: return 404 not found page.

handler500 function: return 500 Internal Server Error page.

3. urls.py

In our base project URLs, we need to import & defined our page function.


#pypro/urls.py

from core import views

handler404 = views.handler404
handler500 = views.handler500

4. settings.py

In our settings.py, we must set debug = False.


#pypro/settings.py

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False

5. Create custom 500 & 404 page Template

Now, we'll create the template for our page, so in the TEMPLATES folder, we need to create an err folder, and inside of this folder, we'll create 404.html & 500.html.

404.html
