It's not a bug. You are assuming that you can pass position arguments to
your model (which would be true if the only arguments taken by __init__
were the fields you declared). This isn't true, since are some implicit
fields created by Django: for example, the automatic primary key field
"id". That's why none of the examples in the documentation use
positional arguments.
So you should always use keyword arguments when initialising a model:
shoutbox(name='jonas', shout='...', pub_date='...')
or
data = {'name': 'jonas', 'shout': '...', 'pub_date': '...'}
s = shoutbox(**data)
