推荐答案

您必须为保全推荐代码创建一个新模型.下面给出了模型语法.

You have to created a new model for hold referral code. below are given model syntax.

import uuid
import base64
from django.db import models
from django.contrib.auth.models import User
from django.utils.translation import ugettext_lazy as _
from django.db.models.signals import post_save
from userena.models import UserenaLanguageBaseProfile
from userena.utils import user_model_label 


class Profile(UserenaLanguageBaseProfile):
    """ Default profile """

    user = models.OneToOneField(User,
                                unique=True,
                                verbose_name=_('user'),
                                related_name='profile')
    referral_code = models.CharField(max_length=300, blank=True, null=True)


    def get_absolute_url(self):
        return u'/profile/show/%d' % self.id
    def generate_verification_code(self):
        # Generate user's verification code
        # TODO: Move this to the model
        return base64.urlsafe_b64encode(uuid.uuid1().bytes.encode("base64").rstrip())[:25]

    def save(self, *args, **kwargs):
        """
        If this is a new user, generate code.
        Otherwise leave as is
        """
        if not self.pk:
            self.referral_code = self.generate_verification_code()
        elif not self.verification_code:
            self.referral_code = self.generate_verification_code()

        return super(Profile, self).save(*args, **kwargs)

在您的模型的最后几行中添加这些行.

add These lines in your last lines your models.py

def create_user_profile(sender, instance, created, **kwargs):
    if created:
        profile, created = Profile.objects.get_or_create(user=instance)

post_save.connect(create_user_profile, sender=User)

上述提及行将在创建用户时创建您的用户个人资料.

Above mention line will create your user profile at the time of creating user.

希望这项工作能为您服务！

Hope this work for you!!!
