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.

Implementing a continuous scroll


Social websites often have the feature of continuous scrolling, which is also known as infinite scrolling. There are long lists of items and as you scroll the page down, new items are loaded and attached to the bottom automatically. In this recipe, we will see how to achieve such an effect with Django and the jScroll jQuery plugin. We'll illustrate this using a sample view showing the top 250 movies of all time from Internet Movie Database (http://www.imdb.com/).

Getting ready

First, download the jScroll plugin from the following link: https://github.com/pklauzinski/jscroll.

Put the jquery.jscroll.js and jquery.jscroll.min.js files from the package in the myproject/site_static/site/js/ directory.

Next, for this example, you will create a movies app with a paginated list view for the movies. You can either create a Movie model or a list of dictionaries with the movie data. Every movie will have rank, title, release year, and rating fields.
