Python Django:request.POST中的值正确，但无法保存表单

在我的注册页面中，我有两个表单UserForm和Profile表单

配置文件表单依赖于配置文件模型，该模型有一个指向用户模型的OneToOneField—Django中的默认用户模型

其思想是，创建用户时，也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()

配置文件模型：

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" 

    else:
        print("INVALID User_FORM")
        print(user_form.errors)
        print("INVALID Profile_FORM")
        print(profile_form.errors)


INVALID User_Form

INVALID Profile_Form

问题：UserForm.is\u valid（）为

True

，但Profile\u Form.is\u valid（）为

False

但在我的请求中，我得到了ProfileForm的所有正确值：

表单中的选项字段不需要值列表。您将有多个选项，但该字段只有一个值

那么，试试这个：

 profile_form = ProfileForm(request.POST)

并计算

装运区

、

装运省

和

装运部门

的值，作为表单中

初始

的一部分

更新： 如果要查看错误，请更改代码：

user_form_valid =  user_form.is_valid()
profile_form_valid = profile_form.is_valid()

if user_form_valid and profile_form_valid:
    # ...
else:
    # print(user_form.errors)
    # print(profile_form.errors)
    # ...

更新#2 您呈现给用户的表单中的选项与您在视图中绑定的表单中的选项不同，尝试初始化尝试找到一种方法来初始化这些选项，为您实例化的每个

ProfileForm

设置相同的值

---

另一方面，我鼓励您在这种情况下使用。

使用：

profile\u form=ProfileForm（request.POST）

返回

\uu init\uuuuuu（）缺少两个必需的位置参数：'province\u list'和'department\u list'

我说的是在构造函数中设置这些字段的选项，而不是值。是的，我理解。但我如何通过

航运区

，

航运省

和

航运部

作为邮政的一部分？我需要放入

ProfileForm（shipping\u deparment=request.POST.get（'shipping\u deparment'）、shipping\u province=request.POST.get（'shipping\u province'）、shipping\u district=request.POST.get（'shipping\u district'）、request.POST）中

？

表单的值是什么？
表单之后的错误是什么？
是否有效？

无法访问该部分，因为：

如果用户表单有效（）和配置文件表单有效（）：

由于

配置文件表单无效，我无法传递该条件。请查看我的代码中的更多详细信息，并告诉我应该在哪里调用
form.errors
。
