Exception Value: UNIQUE constraint failed: accounts_profile.user_id

[Luiz Guilherme Schiefler de Arruda]

Hello folks,

I'm studying Django and everything was ok until this morning. After 
creating a form using inlineformset_factory, I can't create an user. I got 
this error when creating the user inside the form I've created:

Exception Value: 

UNIQUE constraint failed: accounts_profile.user_id


Analising and debugging a little, I think that the error occurs because, on 
this SQL line code (generated automatically by django) it tries to save a 
String inside an integer field (user_id).

Here is the codes:

location = models.CharField(max_length=30, blank=True)
birthdate = models.DateField(null=True, blank=True)

blank=True)

def __str__(self):
return self.user.username

@property
def age(self):
TODAY = datetime.date.today()
if self.birthdate:
return u"%s" % relativedelta.relativedelta(TODAY, self.birthdate).years
else:
return None

@receiver(post_save, sender=User)
def create_or_update_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
instance.profile.save()

forms.py
class FormSignUp(UserCreationForm):
email = forms.CharField(max_length=254, required=True, 
widget=forms.EmailInput())

class Meta:
model = User
fields = ['username', 'email', 'password1', 'password2']

class FormProfile(forms.ModelForm):
class Meta:
model = Profile
fields = ['birthdate', 'gender', 'site_facebook', 'site_twitter', 
'profile_picture']

FormSetProfile = inlineformset_factory(User, Profile, form=FormProfile)




view.py
class CreateUser(CreateView):
    form_class = FormSignUp
    template_name = 'signup.html'
    success_url = reverse_lazy('home')

    def get_context_data(self, **kwargs):
        data = super(CreateUser, self).get_context_data(**kwargs)
        if self.request.POST:
            data['profile'] = FormSetProfile(self.request.POST)
        else:
            data['profile'] = FormSetProfile()
        return data

    def form_valid(self, form):
        context = self.get_context_data()
        profile_formset = context['profile']


        with transaction.atomic():
            form.instance.created_by = self.request.user
            form.instance.updated_by = self.request.user
            self.object = form.save()
        if profile_formset.is_valid():
            profile_formset.instance = self.object
            profile_formset.save() # Linha onde está dando o erro

        return super(CreateUser, self).form_valid(form)

Thanks for your help
