Yes, you are doing something fundamentally wrong. If you define an
__init__ function, db.Model's __init__ won't be called unless you call
it and things won't work if db.Model's __init__ isn't called.
Instead, you want something like
def __init__(self, *args, **kwds):
{your code}
super(Auction, self).__init__(*args, **kwds)
{more of your code}
For example, {your code} could include "kwds.setdefault("title",
"default title")" (Yes, this is the dumb/wrong way to do default
values.)
If you have named arguments, make sure that you pass the right
information to the super's __init__.
Note also that your __init__ will be called when the runtime
constructs an Auction, as it does for query and get results.
FWIW, it's likely that you shouldn't be writing your own __init__
function.
