Introduction Interested in giving back to the community a little? Maybe you’ve found a bug in Django that you’d like to see fixed, or maybe there’s a small feature you want added. Contributing back to Django itself is the best way to see your own concerns addressed. This may seem daunting at first, but it’s really pretty simple. We’ll walk you through the entire process, so you can learn by example. Who’s this tutorial for? See also If you are looking for a reference on how to submit patches,

Here you’ll find short answers to “How do I....?” types of questions. These how-to guides don’t cover topics in depth – you’ll find that material in the Using Django and the API Reference. However, these guides will help you quickly accomplish common tasks. Authentication using REMOTE_USER Writing custom django-admin commands Writing custom model fields Custom Lookups Custom template tags and filters Writing a custom storage system Deploying Django Upgrading Django to a newer version Error rep

This tutorial begins where Tutorial 6 left off. We’re continuing the Web-poll application and will focus on customizing Django’s automatically-generated admin site that we first explored in Tutorial 2. Customize the admin form By registering the Question model with admin.site.register(Question), Django was able to construct a default form representation. Often, you’ll want to customize how the admin form looks and works. You’ll do this by telling Django the options you want when you register th

This tutorial begins where Tutorial 4 left off. We’ve built a Web-poll application, and we’ll now create some automated tests for it. Introducing automated testing What are automated tests? Tests are simple routines that check the operation of your code. Testing operates at different levels. Some tests might apply to a tiny detail (does a particular model method return values as expected?) while others examine the overall operation of the software (does a sequence of user inputs on the site pro

This tutorial begins where Tutorial 3 left off. We’re continuing the Web-poll application and will focus on simple form processing and cutting down our code. Write a simple form Let’s update our poll detail template (“polls/detail.html”) from the last tutorial, so that the template contains an HTML <form> element: <h1>{{ question.question_text }}</h1> {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %} <form action="{% url

This tutorial begins where Tutorial 5 left off. We’ve built a tested Web-poll application, and we’ll now add a stylesheet and an image. Aside from the HTML generated by the server, web applications generally need to serve additional files — such as images, JavaScript, or CSS — necessary to render the complete web page. In Django, we refer to these files as “static files”. For small projects, this isn’t a big deal, because you can just keep the static files somewhere your web server can find it.

This tutorial begins where Tutorial 1 left off. We’ll setup the database, create your first model, and get a quick introduction to Django’s automatically-generated admin site. Database setup Now, open up mysite/settings.py. It’s a normal Python module with module-level variables representing Django settings. By default, the configuration uses SQLite. If you’re new to databases, or you’re just interested in trying Django, this is the easiest choice. SQLite is included in Python, so you won’t nee

This tutorial begins where Tutorial 2 left off. We’re continuing the Web-poll application and will focus on creating the public interface – “views.” Overview A view is a “type” of Web page in your Django application that generally serves a specific function and has a specific template. For example, in a blog application, you might have the following views: Blog homepage – displays the latest few entries. Entry “detail” page – permalink page for a single entry. Year-based archive page – displays

Let’s learn by example. Throughout this tutorial, we’ll walk you through the creation of a basic poll application. It’ll consist of two parts: A public site that lets people view polls and vote in them. An admin site that lets you add, change, and delete polls. We’ll assume you have Django installed already. You can tell Django is installed and which version by running the following command: $ python -m django --version If Django is installed, you should see the version of your installation.

This document explains how to structure and write database migrations for different scenarios you might encounter. For introductory material on migrations, see the topic guide. Data migrations and multiple databases When using multiple databases, you may need to figure out whether or not to run a migration against a particular database. For example, you may want to only run a migration on a particular database. In order to do that you can check the database connection’s alias inside a RunPython
