如何修復無法分配“”：“”必須是“”實例？創建FK模型時？

我想在創建用戶時創建帶視圖的模型，但我得到了一個錯誤：無法分配“<user:test1234”："Customer_info.customer"必須是“Customer”實例。

下面是我擁有的模型，我希望在用戶注冊時自動創建這些模型。

class Customer(models.Model):
      user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)
      points = models.FloatField(default = 0.0)
      ...

class Customer_info(models.Model):
      customer = models.OneToOneField(Customer, on_delete=models.CASCADE)
      deposit = models.FloatField(default = 0.0)

在views.py中注冊這些模型后

def reg(request):
    form = CreateUserForm()
    if "register-btn" in request.POST:
        form = CreateUserForm(request.POST)
        if form.is_valid():
            new_user = form.save()
            login(request, new_user)

            Customer.objects.create(
                user=new_user, points=0.0
            )

            Customer_info.objects.create(
                customer = new_user, deposit = 0.0  
                # HERE IS THE PROBLEM, IN THE customer field
            )

            response = redirect('profile')
            return response
    return render(request, 'main.html')
