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.

Getting detailed error reporting via e-mail


To perform system logging, Django uses Python's built-in logging module. The default Django configuration seems to be quite complex. In this recipe, you will learn how to tweak it in order to send error e-mails with complete HTML, similar to what is provided by Django in the DEBUG mode when an error happens.

Getting ready

Locate the Django project in your virtual environment.

How to do it...

The following procedure will help you send detailed e-mails about errors:

  1. Open the myproject_env/lib/python2.7/site-packages/django/utils/log.py file in a text editor and copy the DEFAULT_LOGGING dictionary to your project's settings as the LOGGING dictionary.

  2. Add the include_html setting to the mail_admins handler, as follows:

    # myproject/conf/base.py or myproject/settings.py
    LOGGING = {
        "version": 1,
        "disable_existing_loggers": False,
        "filters": {
            "require_debug_false": {
                "()": "django.utils.log.RequireDebugFalse",
            },
      ...
