Hey Fu Jiantao,
Django is at 1.2 and things aren't changing much. Pinax is still at
0.7.1 and things are changing quite a bit. Between dot releases we
don't promise backwards compatibility because we aren't at 1.0 too
much. So that means we are constantly playing a game of documentation
catch-up. As we get closer to Pinax 1.0 you'll see our documentation
expand rapidly in quantity and quality.
Of course, if you want to help with that documentation, that would be
appreciated. The issue that you found could certainly make it into the
Sphinx/RestructedText docs so no one else but you has to look through
code to make the same problem work.
