Overview of this book

Do you want to develop reliable and secure applications which stand out from the crowd, rather than spending hours on boilerplate code? Then the Django framework is where you should begin. Often referred to as a 'batteries included' web development framework, Django comes with all the core features needed to build a standalone application. Web Development with Django takes this philosophy and equips you with the knowledge and confidence to build real-world applications using Python. Starting with the essential concepts of Django, you'll cover its major features by building a website called Bookr – a repository for book reviews. This end-to-end case study is split into a series of bitesize projects that are presented as exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. As you progress, you'll learn various practical skills, including how to serve static files to add CSS, JavaScript, and images to your application, how to implement forms to accept user input, and how to manage sessions to ensure a reliable user experience. Throughout this book, you'll cover key daily tasks that are part of the development cycle of a real-world web application. By the end of this book, you'll have the skills and confidence to creatively tackle your own ambitious projects with Django.

When submitting files, we must ensure that there are at least two attributes on the form: method and enctype. You may still also need other attributes, such as action. A form that supports file uploads might look like this:

<form method="post" enctype="multipart/form-data">

File uploads are only available for POST requests. They are not possible with GET requests as it would be impossible to send all the data for a file through a URL. The enctype attribute must be set to let the browser know it should send the form data as multiple parts, one part for the text data of the form, and separate parts for each of the files that have been attached to the form. This encoding...
