Community Catchup (21:50)

• Horror Story with GeoDjango – Alberto García Hierro posts about some of his frustrations with converting over a geo-based project to GeoDjango.
  • Postback Horror Story with GeoDjango

• GeoDjango Dependencies Installed through Apt Get on Ubuntu – Nice wiki information on how to get all of the GeoDjango dependencies installed without a lot of fuss.

  • Rails Wiki: Understanding Polymorphic Associations

• RequestFactory Snippet – This snippet by Simon Willison Makes it easy to create mock request objects in Django, which you can then use for testing view functions directly (bypassing the current test client mechanism which requires views to be assigned to a URLconf before they can be tested).

Tip of the Week (38:04)

This Tip of the Week comes from Eric Holscher in his blog post titled, Using mock objects in django and python testing.

import unittest
class LoadDateutil(TemplateTestCase):
    def test_load(self):
        olddatetime = datetime.datetime
        datetime.datetime = make_datetime(5)
        self.assertEqual(self.render(u'{% load dateutil %}{% ifnight %}Hi{% endifnight %}'), u'')
        datetime.datetime = olddatetime

It’s implementation looks like:

import datetime
def make_datetime(hour):
    class MockDatetime(datetime.datetime):
        @classmethod
        def now(cls):
            return datetime.datetime(2007, 1, 1, hour)
    return MockDatetime

• Mock by Michael Foord – Makes mocking out objects for testing purposes really easy.

• GitPython – Python interface to Git. Uses Mock by Michael Foord to mock out a Git repository.
