The immediate issue here is that your `get_or_create()` call only
passes a value for `wine_name` - if the wine doesn't exist, Django
will try and create it, but doesn't have any of the other fields,
hence the integrity error. You need to use the `defaults` argument to
provide the rest of the data. See the documentation:
http://docs.djangoproject.com/en/1.2/ref/models/querysets/#get-or-create-kwargs

There are a few other issues with this code, which you'll discover
once you've fixed that - eg you start off calling the new Wine object
`wine`, then swap to `winerater`, which will lead to an error.
Similarly you've used `dummy` as the second result from
`get_or_create` but then later refer to `created`.
