在我的“注册”页面中，我有2个表单用户表单和个人资料表单。
个人资料表单依赖于个人资料模型，该模型具有一个OneToOneField到User模型-Django-中的默认User模型。
这个想法是，当创建用户时，还会创建该用户的配置文件：
@receiver(post_save, sender=User)
def update_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
instance.profile.save()
个人资料模型：
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
# birth_date = models.DateField(null=True, blank=True)
dni = models.CharField(max_length=30, blank=True)
#phone_number = models.CharField(max_length=15, blank=True)
shipping_address1 = models.CharField(max_length=100, blank=False)
shipping_address2 = models.CharField(max_length=100, blank=False)
shipping_department = models.CharField(max_length=100, blank=False)
shipping_province = models.CharField(max_length=100, blank=False)
shipping_district = models.CharField(max_length=100, blank=False)
def __str__(self):
return str(self.user.first_name) + "'s profile"
问题：：UserForm.is_valid（）为True，但Profile_Form.is_valid（）为False。
但是在我的请求中，我得到了ProfileForm的所有正确值：
<QueryDict: {'csrfmiddlewaretoken': ['91sJC01vyty3Z9ECjrSop1bouUOF2ZeC9m6XZUgk0nTEH7p6W0DmtuQaB4EBhV22'], 'first_name': ['Juana'], 'last_name': ['Juana'], 'username': ['juana
juana'], 'dni': ['454545'], 'email': ['juana@gmail.com'], 'password1': ['caballo123'], 'password2': ['caballo123'], 'shipping_address1': ['Urb. La Merced Mz.G Lot.32'], 'ship
ping_address2': ['Villa FAP - San Roque'], 'shipping_department': ['Cajamarca'], 'shipping_province': ['Cajamarca'], 'shipping_district': ['Cajamarca']}>
如何正确保存ProfileForm？
显示UserForm和ProfileForm的视图：
@transaction.atomic
def signupView(request):
peru = Peru.objects.all()
department_list = set()
province_list = set()
district_list = set()
for p in peru:
department_list.add(p.departamento)
department_list = list(department_list)
print("Department List: ", department_list)
if len(department_list):
province_list = set(Peru.objects.filter(departamento=department_list[0]).values_list("provincia", flat=True))
print("Provice List: ", province_list)
province_list = list(province_list)
# print("dfsfs", province_list)
else:
province_list = set()
if len(province_list):
district_list = set(
Peru.objects.filter(departamento=department_list[0], provincia=province_list[0]).values_list("distrito",
flat=True))
print("district List: ", district_list)
else:
district_list = set()
if request.method == 'POST':
user_form = SignUpForm(request.POST)
profile_form = ProfileForm(district_list, province_list, department_list, request.POST)
print("This is Profile Form: ", profile_form)
print("Is Profile_Form valid: ", profile_form.is_valid())
if user_form.is_valid() and profile_form.is_valid():
user = user_form.save()
username = user_form.cleaned_data.get('username')
signup_user = User.objects.get(username=username)
customer_group = Group.objects.get(name='Clientes')
customer_group.user_set.add(signup_user)
raw_password = user_form.cleaned_data.get('password1')
user.refresh_from_db() # This will load the Profile created by the Signal
# print(user_form.cleaned_data)
print("Form is valid: district_list, province_list, department_list")
print(district_list, province_list, department_list)
profile_form = ProfileForm(district_list, province_list, department_list, request.POST,
instance=user.profile) # Reload the profile form with the profile instance
profile_form.full_clean() # Manually clean the form this time. It is implicitly called by "is_valid()" method
# print(profile_form.cleaned_data)
profile_form.save() # Gracefully save the form
user = authenticate(username=username, password=raw_password)
login(request, user)
return redirect('cart:cart_detail')
else:
print("INVALID FORM")
user_form = SignUpForm()
profile_form = ProfileForm(district_list, province_list, department_list)
print('end of profile postdata print')
print(profile_form)
print("Profile Data:")
return render(request, 'accounts/signup.html', {
'user_form': user_form,
'profile_form': profile_form
})
此行返回false：
print("Is Profile_Form valid: ", profile_form.is_valid())
个人资料表单：
class ProfileForm(ModelForm):
def __init__(self, district_list, province_list, department_list, *args, **kwargs):
super(ProfileForm, self).__init__(*args, **kwargs)
self.fields['shipping_district'] = forms.ChoiceField(choices=tuple([(name, name) for name in district_list]))
self.fields['shipping_province'] = forms.ChoiceField(choices=tuple([(name, name) for name in province_list]))
self.fields['shipping_department'] = forms.ChoiceField(choices=tuple([(name, name) for name in department_list]))
dni = forms.CharField(label='DNI', max_length=100, required=True)
shipping_address1 = forms.CharField(label='Dirección de envío', max_length=100, required=True)
shipping_address2 = forms.CharField(label='Dirección de envío 2 (opcional)', max_length=100, required=False)
class Meta:
model = Profile
fields = ('dni', 'shipping_address1',
'shipping_address2', 'shipping_department', 'shipping_province', 'shipping_district')
更新1：
else:
print("INVALID User_FORM")
print(user_form.errors)
print("INVALID Profile_FORM")
print(profile_form.errors)
INVALID User_Form
INVALID Profile_Form
<ul class="errorlist"><li>shipping_province<ul class="errorlist"><li>Select a valid choice. Tarata is not one of the available choices.</li></ul></li><li>shipping_district<ul
class="errorlist"><li>Select a valid choice. Estique is not one of the available choices.</li></ul></li></ul>

答案 0 :(得分：1)
表单中的选择字段不期望值列表。您将有多个选项，但是该字段将只有一个值。
因此，请尝试以下操作：
profile_form = ProfileForm(request.POST)
并计算表单中shipping_district的{{1}}，shipping_province和shipping_department的值。
如果要查看错误，请更改您的代码：
__init__您在呈现给用户的表单中的选择与视图中绑定的是不同的，尝试初始化尝试找到一种方法来为每个{{1 }}实例化。
另一方面，我建议您在这种情况下使用FormSet。
