Django Python Cheatsheet

Django is a high-level web framework for building web applications in Python. It follows the “don’t repeat yourself” (DRY) principle and encourages rapid development by providing a clean and pragmatic design. Whether you’re a beginner or an experienced developer, having a Django cheatsheet at your fingertips can save you time and effort. This cheatsheet serves as a quick reference guide to key Django concepts, commands, and best practices.

Getting Started

1. Installation

pip install django

2. Create a Project

django-admin startproject projectname

3. Create an App

cd projectname
python startapp appname

4. Run Development Server

python runserver


5. Define a Model

from django.db import models

class MyModel(models.Model):
    field1 = models.CharField(max_length=100)
    field2 = models.IntegerField()

6. Migrate Database

python makemigrations
python migrate

7. Create Superuser

python createsuperuser


8. Create a View

from django.shortcuts import render

def my_view(request):
    return render(request, 'template_name.html', context)

9. Class-Based Views

from django.views import View

class MyView(View):
    def get(self, request):
        return render(request, 'template_name.html', context)


10. Template Variables

{{ variable }}

11. Template Tags

{% tag %}

12. Template Filters

{{ value|filter }}


13. Create a Form

from django import forms

class MyForm(forms.Form):
    field1 = forms.CharField(max_length=100)
    field2 = forms.IntegerField()

14. Handling Forms in Views

from django.shortcuts import render
from .forms import MyForm

def my_form_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # Process form data
        form = MyForm()

    return render(request, 'template_name.html', {'form': form})

URL Patterns

15. Create URL Patterns

from django.urls import path
from . import views

urlpatterns = [
    path('my-view/', views.my_view, name='my-view'),


16. Create Custom Middleware

class MyMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        # Code to be executed for each request
        response = self.get_response(request)
        # Code to be executed for each response
        return response


17. User Authentication

from django.contrib.auth.decorators import login_required

def my_authenticated_view(request):
    return render(request, 'template_name.html', context)

18. Login and Logout Views

from django.contrib.auth.views import LoginView, LogoutView

urlpatterns = [
    path('login/', LoginView.as_view(), name='login'),
    path('logout/', LogoutView.as_view(), name='logout'),

Static Files

19. Include Static Files in Templates

{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}">

20. Collect Static Files

python collectstatic

Django Admin

21. Customize Django Admin

from django.contrib import admin
from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('field1', 'field2'), MyModelAdmin)

This Django cheatsheet provides a quick reference to essential commands and concepts, but Django is a powerful framework with many more features and options. Refer to the official Django documentation for in-depth information and guidance on specific topics.


1. How do I handle static files in Django?

In Django, static files such as CSS, JavaScript, and images are typically managed using the {% static %} template tag. You include the static files in your templates like this:
{% load static %} <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}">
To collect static files into a single directory for deployment, you can use the following command:
python collectstatic

2. What is the Django ORM, and how do I use it to interact with the database?

Django’s Object-Relational Mapping (ORM) allows you to interact with your database using Python code instead of SQL. You define models as Python classes, and Django takes care of creating the database tables and handling queries. To use the ORM, you create a model, run migrations, and then interact with the database using Django’s query API.

3. How can I secure my Django application?

Securing a Django application involves several steps. Some key practices include:
Use HTTPS: Ensure that your site is served over HTTPS to encrypt data in transit.
Set strong passwords: Encourage users to set strong, unique passwords.
Implement user authentication and authorization: Use Django’s built-in authentication system to manage user logins and permissions.

4. How can I deploy a Django application?

Django applications can be deployed on various hosting platforms. Some popular deployment options include:
Heroku: A cloud platform that simplifies deployment with a straightforward process.
Docker: Package your application and its dependencies into a container for consistent deployment.
Traditional hosting: Deploy on a server using Apache or Nginx with Gunicorn or uWSGI as the application server.

5. What are Django signals, and when should I use them?

Django signals allow decoupled components of a Django application to communicate and respond to actions. When one part of your application triggers a signal, other parts can listen for that signal and respond accordingly. Signals are often used for handling certain events, such as user authentication, where you might want to perform additional actions when a user is created or logged in. They provide a way to keep components loosely coupled while still allowing them to communicate effectively.
