Overview of this book

Django is a web framework that was designed to strike a balance between rapid web development and high performance. It has the capacity to handle applications with high levels of user traffic and interaction, and can integrate with massive databases on the backend, constantly collecting and processing data in real time. Through this book, you'll discover that collecting data from different sources and providing it to others in different formats isn't as difficult as you thought. It follows a task-based approach to guide you through all the web development processes using the Django framework. We’ll start by setting up the virtual environment for a Django project and configuring it. Then you’ll learn to write reusable pieces of code for your models and find out how to manage database schema changes using South migrations. After that, we’ll take you through working with forms and views to enter and list data. With practical examples on using templates and JavaScript together, you will discover how to create the best user experience. In the final chapters, you'll be introduced to some programming and debugging tricks and finally, you will be shown how to test and deploy the project to a remote dedicated server. By the end of this book, you will have a good understanding of the new features added to Django 1.8 and be an expert at web development processes.

Attaching your own navigation


Once you have an app hooked in the CMS pages, all the URL paths under the page node will be controlled by the urls.py file of the app. To add some menu items under this page, you need to add a dynamical branch of navigation to the page tree. In this recipe, we will improve the movies app and add new navigation items under the Movies page.

Getting ready

Let's say that we have a URL configuration for different lists of movies: editor's picks, commercial movies, and independent movies, as shown in the following code:

# movies/urls.py
# -*- coding: UTF-8 -*-
from __future__ import unicode_literals
from django.conf.urls import url, patterns
from django.shortcuts import redirect

urlpatterns = patterns("movies.views",
    url(r"^$", lambda request: redirect("featured_movie_list")),
    url(r"^editors-picks/$", "movie_list", {"featured": True},
        name='featured_movie_list'),
    url(r"^commercial/$", "movie_list", {"commercial": True},
        name="commercial_movie_list...
