UNIQUE constraint failed: user_profile.StudentID error - django

Question

I am getting this error(IntegrityError at /register/) every time I try to create a new user. In user creation form I am creating both User and profile.
here is my models.py
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
StudentID = models.CharField(max_length=8,unique=True)
Branch = models.CharField(max_length=255,choices=Departments,default="CSE")
YearOfStudy = models.IntegerField(default=1)
ContactNumber = PhoneField(help_text='Contact phone number')
image = models.ImageField(default='default.jpeg' , upload_to='profile_pics')
parentsContactNumber = PhoneField(help_text="Parent's phone number")
def __str__(self):
return f'{self.user.username} Profile'
here is forms.py
class UserRegisterForm(UserCreationForm):
email = forms.EmailField()
first_name = forms.CharField()
last_name = forms.CharField()
class Meta:
model = User
fields = ['username','email','first_name','last_name','password1','password2']
class ProfileCreationForm(forms.ModelForm):
class Meta:
model = Profile
fields = ['StudentID','Branch','YearOfStudy','ContactNumber']
here is views.py
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
form1 = ProfileCreationForm(request.POST)
if form.is_valid() and form1.is_valid():
form.save()
form1.save()
username = form.cleaned_data.get('username')
messages.success(request, f'Your account has been created! You are now able to log in')
return redirect('login')
else:
form = UserRegisterForm()
form1 = ProfileCreationForm()
context = {
'form': form,
'form1': form1
}
return render(request, 'user/register.html', context)
here is register.html

Answer 1

You are set unique=True in...
StudentID = models.CharField(max_length=8,unique=True)
So, when you pass student_id from your form at that time you pass the same id in form which is already in your database thus this error is coming.
