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>

Adding and editing values


Until now, we did not look closely at the Display class, although it is used in various incarnations within the application that we set up with CherryPy. The Display class combines a number of functions. It:

  • Displays detailed values of an instance

  • Allows those values to be edited

  • Displays a form that allows us to add a completely new instance

  • Processes the input from the edit and add forms

The reason to bundle these functions is twofold: displaying the labels and values for reading, editing, or adding an instance shares a lot of common logic, and by processing the results within the same class method, we can refer to the action attribute of a <form> element in a way that allows us to mount an instance of the Display class from anywhere in the application tree.
