Single file Django project template from the O'Reilly book Lightweight Django.

Minimal, simplified, deployable, production ready Django app. 33 lines of Python.

Info

Django can be overwhelming when starting out. Most Django projects have a very large codebase broken into dozens of files, but the idea of this Gist is to show that it doesn't have to be large. Many of the components of the default django-admin.py startproject my_project project template are confusing to new users, so this project template only includes the minimum required settings to run an application with one url and one view.

Usage

atheiman

function debug(logString) {
  DEBUG = (typeof DEBUG === "undefined") ? true : DEBUG;
  if (DEBUG)
    console.log('DEBUG: ' + logString);
}

function checkArrayForDuplicates(array, arrayNameStr) {
  // return false if no dups, return array of error strings if dups
  // parameters:
  //   array        | required | Array with potential duplicates
