我已经在 Stackoverflow 中阅读了有关此问题的现有答案。但没有一个对我有用。当我运行 manage.py test 时，我得到以下结果，尽管我的网站运行良好!

唯一有问题的行是我的模型中 UserProfile 和用户之间的关系。在 UserProfile 模型下面。我还单独地、顺序地运行了 makemigrations 和 migrate 等等。但是当我运行测试时，它失败了。我真的不知道。任何帮助将不胜感激!
from django.conf import settings
from django.db import models
from allauth.account.models import EmailAddress
from allauth.socialaccount.models import SocialAccount
import hashlib
class UserProfile(models.Model):
class Meta:
db_table = 'user_profile'
app_label = 'iobserve'
user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='profile')
def __unicode__(self):
return "{}'s profile".format(self.user.username)
def account_verified(self):
if self.user.is_authenticated:
result = EmailAddress.objects.filter(email=self.user.email)
if len(result):
return result[0].verified
return False
def profile_image_url(self):
fb_uid = SocialAccount.objects.filter(user_id=self.user.id, provider='facebook')
if len(fb_uid):
return "http://graph.facebook.com/{}/picture?width=40&height=40".format(fb_uid[0].uid)
return "http://www.gravatar.com/avatar/{}?s=40".format(hashlib.md5(self.user.email).hexdigest())
请您参考如下方法:
您的 iobserve 应用没有任何迁移，并且您不能从未迁移的应用到已迁移的应用建立关系，例如 OneToOneField。
您需要运行 manage.py makemigrations iobserve 来为 iobserve 应用程序创建初始迁移。只有当初始迁移存在时，没有任何应用标签的 manage.py makemigrations 才会为该应用创建新的迁移。
