Question

我成功地遵循了https://tools.ietf.org/html/rfc8017#section-4.1教程，一切似乎都还不错。然后，我创建了一个Profile模型，并通过POST请求和管理面板设法创建了它的对象。然后，我创建了信号，以便可以在用户注册后立即创建配置文件。经过一番尝试和错误之后，我终于做到了，并决定将数据库刷新。当我尝试这样做并运行python manage.py flush时，出现此错误：

raise ValueError("Table %s does not exist" % table_name)
ValueError: Table allauth_socialapp does not exist

我已经尝试为每个已安装的应用执行python manage.py迁移，但是似乎没有任何效果，并且已经尝试删除Profile模型及其正在使用的接收器，但这不能解决问题。还尝试删除sqlite文件和所有迁移，但没有帮助。

我的 models.py 文件如下所示：

class Profile(models.Model):
GENDER_CHOICES = (
    ('Male', 'Male'),
    ('Female', 'Female')
)

user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
interests = models.CharField(max_length=100, null=True)
gender = models.CharField(max_length=6, choices=GENDER_CHOICES, null=True)

def __str__(self):
    return f"{self.user}'s Profile"


@receiver(user_signed_up)
def user_registered(sender, request, user, **kwargs):
    print(f"Created profile for {   user}")
    Profile.objects.create(user=user)
    """Creates the Profile after user registers"""

和我的 settings.py 文件：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'rest_auth.registration',
    'core'
]


REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.TokenAuthentication',
    ],
}

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
SITE_ID = 1

有人可以帮我吗？我不知道该怎么办，也无法在线真正找到答案。

Answer 1

尝试使用python SELECT ROW_NUMBER() OVER(PARTITION BY countryname ORDER BY eventid,countryname,place asc) AS Row,* FROM competitormainviewpoints2021isrc ORDER BY row,eventid,place ASC

如果此操作无效，则可以删除manage.py makemigrations AppName和migration folder并尝试。

Answer 2

通过将'allauth.socialaccount'添加到我的INSTALLED_APPS并进行迁移来解决此问题。现在一切正常。

Django：ValueError表allauth_socialapp不存在
