Overview of this book

<p>Building your own Python web applications provides you with the opportunity to have great functionality, with no restrictions. However, creating web applications with Python is not straightforward. Coupled with learning a new skill of developing web applications, you would normally have to learn how to work with a framework as well.</p> <p><em>Python 3 Web Development Beginner's Guide</em> shows you how to independently build your own web application that is easy to use, performs smoothly, and is themed to your taste – all without having to learn another web framework.</p> <p>Web development can take time and is often fiddly to get right. This book will show you how to design and implement a complex program from start to finish. Each chapter looks at a different type of web application, meaning that you will learn about a wide variety of features and how to add them to your custom web application. You will also learn to implement jQuery into your web application to give it extra functionality. By using the right combination of a wide range of tools, you can have a fully functional, complex web application up and running in no time.</p>

Chapter 4. Tasklist II: Databases and AJAX

In this chapter, we will refactor our tasklist application. It will use a database engine on the server to store items and will use jQuery's AJAX functionality to dynamically update the contents of the web application. On the server side, we will learn how to use Python's bundled SQLite database engine. On the presentation side, we will encounter jQuery UI's event system and will learn how to react to mouse clicks

In this chapter, we shall:

  • Learn some benefits of using a database engine

  • Get familiar with SQLite, a database engine distributed with Python

  • Implement a password database with SQLite

  • Learn how to design and develop a database-driven tasklist application

  • Implement a test framework

  • Learn how to make a web application more responsive using AJAX calls

  • See how to implement interactive applications without <form> elements

So let's get on with it...
