自定义用户模型：

class User(AbstractBaseUser):
    id = models.AutoField(primary_key=True)
    username = models.CharField(max_length=30)
    email = models.EmailField(unique=True,max_length=75)
    test = models.CharField(max_length=20)

    USERNAME_FIELD = 'email'

    class Meta:
        managed = False
        db_table = 'auth_user'

在运行./manage.py migrate时，我收到以下错误：

django.db.utils.IntegrityError: (1215, 'Cannot add foreign key constraint')

SHOW ENGINE INNODB STATUS在 mysql 上显示：

2015-07-12 19:29:25 133f4a000 Error in foreign key constraint of table edutraffic/#sql-55ea_17a:
 FOREIGN KEY (`user_id`) REFERENCES `auth_user` (`id`):
Cannot resolve table name close to:
 (`id`)

所以，我删除了整个数据库并重新创建它，仍然得到同样的错误。

settings.py文件：

AUTH_USER_MODEL = 'users.User'
INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',
    'allauth',
    'allauth.account',
    'rest_auth.registration',
    'allauth.socialaccount',
    'allauth.socialaccount.providers.facebook',
    'allauth.socialaccount.providers.google',

    'users',
)

您已设置managed为False，这意味着 Django 不会创建表。删除该行，或手动创建表。
