django.db.utils.IntegrityError: NOT NULL constraint failed:
core_profile.user_id
i'm having this ERROR after submit a form that i made to let user complete profile information just after SignUp's email confirmation. Look at this diagram
some of my code:
models.py
from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
birth_date = models.DateField(null=True, blank=True)
birth_place = models.CharField(max_length=80, verbose_name= ("Lieu de
Naissance"))
email_confirmed = models.BooleanField(default=False)
adress = models.CharField(max_length=80, verbose_name=("Adresse"))
adress_complement = models.CharField(max_length=80, verbose_name=
("Complément d'Adresse"))
city = models.CharField(max_length=80, verbose_name=("Ville"))
zip_code = models.IntegerField(null=True, blank=True)
drive_licence_num = models.CharField(max_length=80, verbose_name=("N° du
Permis de conduire"))
social_secu_num = models.IntegerField(null=True, blank=True)
phone_number = models.IntegerField(null=True, blank=True)
@receiver(post_save, sender=User)
def update_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
instance.profile.save()
forms.py
from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from mysite.core.models import Profile
class SignUpForm(UserCreationForm):
email = forms.EmailField(max_length=254, help_text='Required. Inform a
valid email address.')
class Meta:
model = User
fields = ('first_name', 'last_name', 'email', 'username', 'password1',
'password2',)
class ProfileForm(forms.ModelForm):
class Meta:
model = Profile
fields = ('birth_date','birth_place', 'adress', 'adress_complement',
'city', 'zip_code', 'drive_licence_num', 'social_secu_num',
'phone_number')
views.py (complete_profile view)
def complete_profile(request):
#if email_confirmed == True:
if request.user.is_authenticated():
if request.method == 'POST':
form = ProfileForm(request.POST)
if form.is_valid():
form.save()
return render(request, 'home.html')
else:
form = ProfileForm()
return render(request, 'complete_profile.html', {'form': form})
else:
return render(request, 'login.html')
回答1:
You may need to pass instance request.user.profile to the form.
def complete_profile(request):
if request.user.is_authenticated():
if request.method == 'POST':
form = ProfileForm(request.POST, instance=request.user.profile)
if form.is_valid():
#form.instance.user = request.user
form.save()
return render(request, 'home.html')
else:
form = ProfileForm()
return render(request, 'complete_profile.html', {'form': form})
else:
return render(request, 'login.html')
回答2:
form = ProfileForm(request.POST,instance=request.user.profile)
if form.is_valid():
form.save()
try this
