Book Description

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.

They are save(), create_thumbnail(), and get_thumbnail_picture_url(). When the model is being saved, we will trigger the creation of the thumbnail. When we need to show the thumbnail in a template, we can get its URL using {{ quote.get_thumbnail_ picture_url }}. The method definitions are as follows: #
