別のモデルの列を外部キーとしてuserprofileを拡張しようとしています。しかし、そのスローエラーメッセージを保存している間。
Models.py:
class Team_Profile(models.Model):
team_name = models.CharField(max_length=200, unique=True)
class UserProfile(models.Model):
user = models.OneToOneField(User)
team_name = models.ForeignKey(Team_Profile)
def __str__(self):
return "%s's profile" % self.user
def save(self, *args, **kwargs):
try:
existing = UserProfile.objects.get(user=self.user)
self.id = existing.id
except UserProfile.DoesNotExist:
pass
models.Model.save(self, *args, **kwargs)
def create_user_profile(sender, instance, created, **kwargs):
if created:
created = UserProfile.objects.get_or_create(user=instance)
post_save.connect(create_user_profile, sender=User)
以下は私のviews.pyです:
Views.py:
data = request.POST.copy()
team = data['team_hidden']
try:
team_name = Team_Profile.objects.get(team_name=team)
except Team_Profile.DoesNotExist:
team_profile = Team_Profile()
team_profile.team_name = team
team_profile.save()
try:
user=User.objects.get(username=name)
return render_to_response("user_exist.html", {'media_url':media_url})
except User.DoesNotExist:
user= User.objects.create_user(name,User.email,User.password)
user.first_name=first_name
user.last_name=last_name
user.save()
userprofile = UserProfile()
userprofile.user = user
userprofile.team_name = Team_Profile.objects.get(team_name=team)
userprofile.save()
さらに情報が必要な場合はお知らせください。どんな助けでも大歓迎です。
