Overview of this book

Django is a web framework that was designed to strike a balance between rapid web development and high performance. It has the capacity to handle applications with high levels of user traffic and interaction, and can integrate with massive databases on the backend, constantly collecting and processing data in real time. Through this book, you'll discover that collecting data from different sources and providing it to others in different formats isn't as difficult as you thought. It follows a task-based approach to guide you through all the web development processes using the Django framework. We’ll start by setting up the virtual environment for a Django project and configuring it. Then you’ll learn to write reusable pieces of code for your models and find out how to manage database schema changes using South migrations. After that, we’ll take you through working with forms and views to enter and list data. With practical examples on using templates and JavaScript together, you will discover how to create the best user experience. In the final chapters, you'll be introduced to some programming and debugging tricks and finally, you will be shown how to test and deploy the project to a remote dedicated server. By the end of this book, you will have a good understanding of the new features added to Django 1.8 and be an expert at web development processes.

Creating a model mixin with URL-related methods


For every model that has its own page, it is good practice to define the get_absolute_url() method. This method can be used in templates and also in the Django admin site to preview the saved object. However, get_absolute_url() is ambiguous as it returns the URL path instead of the full URL. In this recipe, we will see how to create a model mixin that allows you to define either the URL path or the full URL by default, generate the other out of the box, and take care of the get_absolute_url() method that is being set.

Getting ready

If you haven't done it yet, create the utils package to save your mixins. Then, create the models.py file in the utils package (alternatively, if you create a reusable app, put the mixins in the base.py file in your app).

How to do it…

Execute the following steps one by one:

  1. Add the following content to the models.py file of your utils package:

    # utils/models.py
    # -*- coding: UTF-8 -*-
    from __future__ import unicode_literals...
