Practical Django Projects, Second Edition

James Bennett978-1-4302-1939-2

In this book, you’ll see how Django can help you achieve both of these goals—rapid
application development and flexible, reusable code—through both the tools it provides
to you directly and the development practices that it makes possible. I’ll guide you
through the development of several example applications and show you how the various
components and applications bundled with Django can help you write less code at each
stage of the development process. You’ll also see first-hand a number of best practices for
reusable code and learn how you can apply them in your own applications. Plus, you’ll
learn how to integrate existing third-party libraries into Django-powered applications to
minimize the amount of code you’ll need to write from scratch.
