• RESTful APIs With Tastypie

  by Daniel Lindsley

  Providing full-featured REST APIs is an increasingly popular request. Tastypie allows you to easily implement a customizable REST API for your Python or Django applications.

  Who am I? (Primary author of Tastypie)
  Why REST?
  A touch of philosophy

  Use HTTP the best we can
  Flexible serialization (not everyone wants JSON)
  What you can GET should be able to be POST/PUT
  Should be reasonable by default but easy to extend
  URIs Everywhere!
  Why Tastypie?

  Works with Django
  Full GET/POST/PUT/DELETE/PATCH
  Any data source (Not just ORM)
  Designed to be extensible
  Supports a variety of serialization formats (JSON/XML/YAML/bplist)
  URIs everywhere by default
  Lots of hooks for customization
  Demonstrate a simple setup

  Then explore the API based on that trivial setup
  Demonstrate adding authentication/authorization

  Demonstrate adding custom serialization
  Demonstrate adding a different data source
  Demonstrate adding a custom endpoint

• Cache Rules Everything Around Me

  by Noah Silas and Jacob Burch

  This talk aims to briefly introduce the core concepts of caching and covers the best practices of implementing them, using a small variety of python web frameworks (Flask, Django) for example code.

  "Are you caching?" is a question asked early on in any yarn on web scaling advice. These conversations are much better steered by asking a more open and difficult questions "What is your caching strategy?" and “How are you implementing it?” This talk aims to briefly introduce the core concepts of caching and quickly moves to cover the best practices using Django and Flask for example code. We will let the audience know what the important questions to ask are, give them advice on how to implement the right answers, and when even the built-in core backend isn’t enough, point them to more advanced techniques and the right third party tools.

  Important questions covered:

  • Why am I caching in the first place? Do I have to?
  • What is your caching strategy?
  • What are examples of good caching strategies?
  • Where do I put my cache code?
  • How dynamic is my content? Could I use a published cache?
  • Should I cache Python objects/classes, or base Python types?
  • Caching
  • Django
  • Python
