将模型引入到django-userena的表单字段中

Question

我正在使用django-userena身份验证。我试图将models.py中的性别定义模型引用到forms.py中以显示在用户注册中，但它在关键字arg（forms.py，第23行）后面显示非关键字arg中的SyntaxError。我不知道如何正确引用它。请帮忙！！！

models.py：

class Profile(UserenaLanguageBaseProfile): 
    GENDER_CHOICES = (
     (1, _('Male')), 
     (2, _('Female')), 
    ) 

    gender = models.PositiveSmallIntegerField(_('gender'), 
               choices=GENDER_CHOICES, 
               blank=False, 
               null=False) 

forms.py：

from django import forms 
from userena.models import UserenaLanguageBaseProfile 
from accounts.models import Profile 
from userena.forms import SignupForm 

class SignupFormExtra(SignupForm): 
    gender = forms.PositiveSmallIntegerField(label=_(u'Gender'), 
              'gender', 
              required=True) 

    first_name = forms.CharField(label=_(u'First name'), 
           max_length=30, 
           required=True) 

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

尝试forms.ChoiceField https://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.ChoiceField

class SignupFormExtra(SignupForm): 
    gender = forms.ChoiceField(label=_(u'Gender'), choices=GENDER_CHOICES, default=1 
             required=True)
