Hi,
I have the following two models:
class AcceptedRoleAbstract(models.Model):
'''
Represents a User that should accept a role
E.g.: Discussant, Reviewer
'''
user = models.ForeignKey(User)
accepted = models.NullBooleanField(help_text=_("The reviewer
agreed to make the review"))
updated = models.DateTimeField(auto_now=True)
created = models.DateTimeField(auto_now_add=True)
class Discussant(AcceptedRoleAbstract):
'''
Represents a discussant
'''
submission = models.OneToOneField(Submission)
class Meta:
verbose_name = _('discussant')
verbose_name_plural = _('discussants')
class Submission(models.Model):
'''
Represents a submitted paper with its author.
'''
presenter = models.OneToOneField(Attendee) # ForeignKey(Attendee,
help_text=_('Choose the attendee who will present the paper'))
coauthors = models.TextField(blank=True, help_text=_('Coauthors
separated by commas (,)'))
title = models.CharField(max_length=255, help_text=_('Presentation
title'))
abstract = models.TextField(help_text=_('Abstract'))
document = models.FileField(upload_to=get_submission_upload_to,
help_text=_('Uploaded version'))
accepted = models.NullBooleanField(help_text=_('Accepted /
Rejected'))
topic = models.ForeignKey(Topic)
section = models.ForeignKey(Section, null=True, blank=True)
updated = models.DateTimeField(auto_now=True)
created = models.DateTimeField(auto_now_add=True)
and run this code in my test
submission = models.Submission.objects.create
(**self.submission_data.copy())
discussant = models.Discussant.objects.create(
user=User.objects.get(pk=2),
accepted=True,
submission=submission)
what gives my an "IntegrityError: PRIMARY KEY must be unique"
could someone enlighten me please how to assign do what I want
correctly?
thanks, Viktor
