In December 2008, while working for NASA's Science Mission Directorate, my team began to use Django and Pinax. We needed to make all the forms in Pinax Section 508 compatible, and the thought of going through all of 30+ forms and rewriting {{ form }} as a block of {% for field in form %} with all the template logic seemed like way too much work.
So with the encouragement of Katie Cunningham, James Tauber and Jannis Leidel I took the Django docs on forms and combined it with Dragan Babic's excellent Uni-Form css/javascript library and created the ubiquitous as_uni_form filter. After that, fixing all the forms in Pinax to be section 508 compliant was trivial.
Not long before PyCon 2009 James Tauber suggested the {% uni_form form helper %} API, where one could trivially create forms without writing any HTML.
At PyCon 2009 Jannis Leidel helped me through releasing the 0.3 release of django-uni-form on PyPI. It was also at that PyCon that I believe I switched the library from Google Project Hosting to Github.
