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.

Inserting a map into a change form


Google Maps offer a JavaScript API to insert maps into your websites. In this recipe, we will create a locations app with the Location model and extend the template of the change form in order to add a map where an administrator can find and mark geographical coordinates of a location.

Getting ready

We will start with the locations app that should be put under INSTALLED_APPS in the settings. Create a Location model there with a title, description, address, and geographical coordinates, as follows:

# locations/models.py
# -*- coding: UTF-8 -*-
from __future__ import unicode_literals
from django.db import models
from django.utils.translation import ugettext_lazy as _
from django.utils.encoding import python_2_unicode_compatible

COUNTRY_CHOICES = (
    ("UK", _("United Kingdom")),
    ("DE", _("Germany")),
    ("FR", _("France")),
    ("LT", _("Lithuania")),
)

@python_2_unicode_compatible
class Location(models.Model):
    title = models.CharField(_("title"...
