Web Development with Django

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.

These classes are used for specific types of test cases based on the capabilities they provide to the developer.

Let us take a quick look at them.

SimpleTestCase

This class is derived from the TestCase class provided by Django's test module and should be used for writing simple test cases that test the view functions. Usually, the class is not preferred when your test case involves making database queries. The class also provides a lot of useful features, such as the following:

  • The ability to check for exceptions raised by a view function
  • The ability to test form fields
  • A built-in test client
  • The ability to verify a redirect by a view function
  • Matching the equality of two HTML, JSON, or XML outputs generated by...
