For some years, web development has evolved through frameworks. Web development has become more efficient and has improved in quality. Django is a very sophisticated and popular framework. A framework is a set of tools designed to facilitate and standardize development. It allows the developer to benefit from very practical tools to minimize the development time. However, developing with frameworks requires knowledge about the framework and its proper usage. This book uses a step-by-step pedagogy to help novice developers learn how to easily deal with the Django framework. The examples in this book explain the development of a simple web tool: a text-based task manager.
Chapter 1, Django's Position on the Web, gives a short history of the Web and its evolution. It explains what a framework and MVC pattern are. It ends with a presentation of Django.
Chapter 2, Creating a Django Project, deals with the installation of the necessary software to use Django. At the end of this chapter, you will have a development environment that is ready to code.
Chapter 3, Hello World! with Django, describes Django routing after a reminder of regular expressions. It ends with an example of a simple controller that displays "Hello world!" on the user's browser.
Chapter 4, Working with Templates, explains how Django templates work. It covers the basics of the template language as well as the best practices for architecture templates and URL creation.

Django 1.6
This book is for Python developers who want to learn how to create a website with a quality framework. The book is also for web developers who use other languages such as PHP and who wish to improve the quality and maintainability of their website. The book is for anyone who has Python basics and web basics as well as who wishes to work on one of the most advanced frameworks today.
In this book, you will find a number of styles of text that distinguish between different kinds of information. The following are some examples of these styles, and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the settings.py
directive."
A block of code is set as follows:
from django.conf.urls import patterns, include, url from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Examples: # url(r'^$', 'Work_msanager.views.home', name='home'), # url(r'^blog/', include('blog.urls')), url(r'^admin/', include(admin.site.urls)), )
Any command-line input or output is written as follows:
root@debian: wget https://raw.github.com/pypa/pip/master/contrib /get-pip.py root@debian:python3 get-pip.py
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Click on Advanced System Settings."
