'SignupFormExtra' 对象没有属性“_meta”

'SignupFormExtra' object has no attribute '_meta'

这是我第一次在 Django 中使用 userena。我想覆盖 userena 的注册表单,现在出现错误。

from userena import settings as userena_settings
from userena.models import UserenaSignup
from userena.utils import get_profile_model

class SignupFormExtra(SignupForm):
"""
A form to demonstrate how to add extra fields to the signup form, in this
case adding the first and last name.


"""
cellPhone = forms.CharField(label=_(u'CellPhone'),
                             max_length=30,
                             required=False)
first_name = forms.CharField(label=_(u'First name'),
                             max_length=30,
                             required=False)

last_name = forms.CharField(label=_(u'Last name'),
                            max_length=30,
                            required=False)

def save(self):
    """
    Override the save method to save the first and last name to the user
    field.

    """
    # First save the parent form and get the user.
    new_user = super(SignupFormExtra, self).save()

    # Get the profile, the `save` method above creates a profile for each
    # user because it calls the manager method `create_user`.
    # See: https://github.com/bread-and-pepper/django-userena/blob/master/userena/managers.py#L65
    new_user = get_profile_model()

    new_user.first_name = self.cleaned_data['first_name']
    new_user.last_name = self.cleaned_data['last_name']
    new_user.cellPhone = self.cleaned_data['cellPhone']
    new_user.save(self)

    # Userena expects to get the new user from this form, so return the new
    # user.
    return new_user

实际上我在 model.py 中有 class 个个人资料,并像这样提到 userena:

class Profile(UserenaBaseProfile):
user = models.OneToOneField(User,
                            on_delete=models.CASCADE,
                            unique=True,
                            verbose_name=_('user'),
                            related_name='my_profile')

谁能帮我解决一下?

你不需要这部分:

new_user = get_profile_model()

你从上一个命令得到 new_user,只需保存它并从 new_user.save()

中删除 self

new_user.save(自己) -> new_user.save()

def save(self):
    """
    Override the save method to save the first and last name to the user
    field.

    """
    # First save the parent form and get the user.
    new_user = super(SignupFormExtra, self).save()  
    new_user.first_name = self.cleaned_data['first_name']
    new_user.last_name = self.cleaned_data['last_name']
    new_user.cellPhone = self.cleaned_data['cellPhone']
    new_user.save()

    # Userena expects to get the new user from this form, so return the new
    # user.
    return new_user
