Django Nullable Foreign Key not Working

I have two models formatted as follows:

class Attachment(models.Model):
    # ...

class Message(models.Model):
    # ...
    attachment = models.ForeignKey(Attachment, blank=True, default=None, null=True)
    # ...

I have tried various solutions found every where online...but cannot make it work! Here are some of the combinations I have tried:

I keep getting the following error whenever I try to save a message with no attachment.

IntegrityError: myapp_message.attachment_id may not be NULL

I am using SQLite if that is significant. Why isn't what I am doing working?

did you modify your model after doing syncdb? If that's the case, you should delete your table and syncdb again.
