coders alike). Once the formalities are over, we describe how each concept fits into the
world of Django as well as what its philosophies are and how it may differ from other
We b ap pl i c at io n f r am ewo r ks .
Part II, “Django in Depth”
Part II covers all the basic components of the framework, laying the foundation for the
example applications in Part III, “Django Applications by Example.”
Chapter 4, “Defining and Using Models”
In Chapter 4, learn how to define and work with your data model, including the basics
of Django’s object-relational mapper (ORM) from simple fields up to complex relations.
Chapter 5, “URLs, HTTP Mechanisms, and Views”
This chapter goes into detail on how Django handles URL processing and the rest of
the HTTP protocol, including middleware layers, as well as how to use Django’s time-
saving generic views, and how to write custom or partially custom views from scratch.
Chapter 6, “Templates and Form Processing”
Chapter 6 covers the final major piece of the framework, where we explore Django’s
template language and its form-handling mechanisms. It covers how to display data to
your users and get data back from them.
Part III, “Django Applications by Example”
In Part III, we create four distinct applications, each highlighting a different aspect or
component of Django development, both to introduce new general ideas and to expand
on the concepts found in Parts I and II.
Chapter 7, “Photo Gallery”
In Chapter 7, learn how to apply the “Don’t Repeat Yourself” convention to your URL
structure and create a new thumbnail-creating image form field, while you make a sim-
ple photo gallery application.
Chapter 8, “Content Management System”
Chapter 8 contains two related approaches to creating a CMS or CMS-like system and
covers the use of a number of “contrib” Django applications.
Chapter 9, “Liveblog”
Chapter 9 covers writing a “liveblog”—a site that makes use of advanced JavaScript
techniques, serves as a backdrop for applying AJAX to a Django project, and shows how
easy it is to use any AJAX toolkit you want.
Chapter 10, “Pastebin”
In Chapter 10, learn the power of Django’s generic views as we create a pastebin using
almost no custom logic whatsoever.
