Question

如何制作一个用户注册表单，其中包含一个模型字段作为必填字段？

就像我希望college字段在注册页面上显示为下拉菜单

my models.py

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    college = models.ForeignKey(College, on_delete=models.CASCADE)


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


class College(models.Model):
    col = models.CharField(max_length=100)

    def __str__(self):
        return self.col

my forms.py

class UserForm(UserCreationForm):
    col = College.objects.all()
    password1 = forms.CharField(widget=forms.PasswordInput)
    password2 = forms.CharField(widget=forms.PasswordInput)
    college = forms.ChoiceField(widget=forms.Select(choices=col))

class Meta:
    model = User
    fields = ('username', 'college', 'password1', 'password2',)

并且views.py包含：

def signup(request):
if request.method == 'POST':
    form = UserForm(request.POST)
    if form.is_valid():
        user = form.save()
        user.refresh_from_db()
        user.save()
        raw_password = form.cleaned_data.get('password1')
        user = authenticate(username=user.username, password=raw_password)
        login(request, user)
        return redirect('home')
else:
    form = UserForm()
return render(request, 'registration_form.html', {'form': form})

更新

了解了ModelChoiceField并在forms.py中进行了这些更改：

class UserForm(UserCreationForm):
password1 = forms.CharField(widget=forms.PasswordInput)
password2 = forms.CharField(widget=forms.PasswordInput)
college = forms.ModelChoiceField(queryset=College.objects.all(), empty_label=None)

class Meta:
    model = User
    fields = ('username', 'college', 'password1', 'password2')

但所选择的大学没有保存在个人资料中

管理员部分也发出RelatedObjectDoesNotExist at /admin/login/错误

如何在注册期间为用户提供可供选择的模型字段？
