Effective Django — Effective Django. The Django template language. This document explains the language syntax of the Django template system.
If you’re looking for a more technical perspective on how it works and how to extend it, see The Django template language: for Python programmers. Django’s template language is designed to strike a balance between power and ease. It’s designed to feel comfortable to those used to working with HTML. If you have any exposure to other text-based template languages, such as Smarty or Jinja2, you should feel right at home with Django’s templates. Philosophy If you have a background in programming, or if you’re used to languages which mix programming code directly into HTML, you’ll want to bear in mind that the Django template system is not simply Python embedded into HTML.
Templates¶ A template is simply a text file. A template contains variables, which get replaced with values when the template is evaluated, and tags, which control the logic of the template.

Field options¶ The following arguments are available to all field types.
All are optional. null¶ Field.null¶ If True, Django will store empty values as NULL in the database. Avoid using null on string-based fields such as CharField and TextField because empty string values will always be stored as empty strings, not as NULL. For both string-based and non-string-based fields, you will also need to set blank=True if you wish to permit empty values in forms, as the null parameter only affects database storage (see blank). Note When using the Oracle database backend, the value NULL will be stored to denote the empty string regardless of this attribute. If you want to accept null values with BooleanField, use NullBooleanField instead. blank¶

Django - Full Stack Python. Django is a widely-used Python web application framework with a "batteries-included" philosophy.
The principle behind batteries-included is that the common functionality for building web applications should come with the framework instead of as separate libraries. For example, authentication, URL routing, a templating system, an object-relational mapper (ORM), and database schema migrations (as of version 1.7) are all included with the Django framework. Simplifying Django. The following comes to you from Julia Elman and Mark Lavin.
Julia is a a hybrid designer/developer who has been working her brand of web skills since 2002; and Mark is the Development Director at Caktus Consulting Group in Carrboro, NC where he builds scalable web applications with Django. Together, they are working on Lightweight Django, a book due out later this year that explores bringing Django into modern web practices. Despite Django’s popularity and maturity, some developers believe that it is an outdated web framework made primarily for “content-heavy” applications. Since the majority of modern web applications and services tend not to be rich in their content, this reputation leaves Django seeming like a less than optimal choice as a web framework. Let’s take a moment to look at Django from the ground up and get a better idea of where the framework stands in today’s web development practices.
