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 and using the Fabric deployment script


Usually, to update your site, you have to perform repetitive tasks such as setting a maintenance page, stopping cron jobs, creating a database backup, pulling new code from a repository, migrating databases, collecting static files, testing, starting cron jobs again, and unsetting the maintenance page. That's quite a tedious work, where mistakes can occur. Also, you need not forget the different routines for staging site (the one where new features can be tested) and production site (which is shown to the public). Fortunately, there is a Python library called Fabric that allows you to automate these tasks. In this recipe, you will learn how to create fabfile.py, the script for Fabric, and how to deploy your project on staging and production environments.

The Fabric script can be called from the directory that contains it, as follows:

(myproject_env)$ fab staging deploy

This will deploy the project on the staging server.
