Here is the traceback from one of the times it screwed up. gah, I expect
this is not good for homestar runner, maybe something deeply wrong in my
model code?
The weird thing is now I just had no problem like 10 times in a row, and
other times the js app fails when it makes the same request (
/bookings/by_date/2010-08-18 ). But when I hit the same thing in the browser
or manually trigger the ajax code from the firebug console, it never fails.
Any clues to the meaning of this traceback are most appreciated.
