扩展 django 用户模型和错误

Question

django 1.8.2

这是我的模型：

class AppUser(AbstractUser):
    _SEX = (
        ('M', 'Male'),
        ('F', 'Female'),
    )
    _pregex  = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
    phone    = models.CharField(validators=[_pregex], max_length=16, blank=True)
    gender   = models.CharField(max_length=1, blank=True, choices=_SEX)
    birthday = models.DateField(blank=True)
    vericode = models.CharField(max_length=40, blank=True) # verification code over SMS?
    verified = models.DateTimeField(null=True) # datetime stored when verification happened

    @property
    def age(self):
        today = date.today()
        return today.year - self.birthday.year - ((today.month, today.day) < (self.birthday.month, self.birthday.day))

这是我的设置：

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

# register externals
EXTERNAL_LIBS_PATH = os.path.join(BASE_DIR, "_externals", "libs")
EXTERNAL_APPS_PATH = os.path.join(BASE_DIR, "_externals", "apps")
APPS_PATH = os.path.join(BASE_DIR, "apps")
sys.path = ["", EXTERNAL_APPS_PATH, EXTERNAL_LIBS_PATH, APPS_PATH] + sys.path

# TEST PATH
TEST_ASSETS = os.path.join(BASE_DIR, "_test")

# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/1.8/howto/deployment/checklist/

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True

ALLOWED_HOSTS = []

# Application definition
INSTALLED_APPS = (
    'suit',
    'django.contrib.auth',
    'django.contrib.admin',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.postgres',
    'cacheops',
    'rest_framework',
    'rest_framework.authtoken',
    'corsheaders',
    'djoser',
    'consents'
)

# Custom model for Auth
# AUTH_USER_MODEL = 'consents.AppUser'

我的文件夹结构是这样的

app
  -settings.py etc
apps
  -consents

在 settings.py 我添加了应用程序路径： APPS_PATH = os.path.join(BASE_DIR, "apps") 到 sys.path,

当我运行 python manage.py syncdb（或其他任何东西）时，我得到了这个：

(cmr) F:\_Projects\cmr\containers\backend>python manage.py syncdb
F:\_Projects\cmr\.venv\cmr\lib\importlib\_bootstrap.py:321: RemovedInDjango19Warning: django.contrib.contenttypes.generic is deprecated and will be removed in Django 1.9. Its contents have been moved to the fields, forms, and admin submodules of django.contrib.contenttypes.
  return f(*args, **kwds)

SystemCheckError: System check identified some issues:

ERRORS:
auth.User.groups: (fields.E304) Reverse accessor for 'User.groups' clashes with reverse accessor for 'AppUser.groups'.
        HINT: Add or change a related_name argument to the definition for 'User.groups' or 'AppUser.groups'.
auth.User.user_permissions: (fields.E304) Reverse accessor for 'User.user_permissions' clashes with reverse accessor for 'AppUser.user_permissions'.
        HINT: Add or change a related_name argument to the definition for 'User.user_permissions' or 'AppUser.user_permissions'.

        HINT: Add or change a related_name argument to the definition for 'AppUser.groups' or 'User.groups'.
consents.AppUser.user_permissions: (fields.E304) Reverse accessor for 'AppUser.user_permissions' clashes with reverse accessor for 'User.user_permissions'.
        HINT: Add or change a related_name argument to the definition for 'AppUser.user_permissions' or 'User.user_permissions'.

如果我在设置中取消注释此行

# AUTH_USER_MODEL = 'consents.AppUser'

我收到另一个错误：

ValueError: Dependency on unknown app: consents

我只需要向默认用户模型添加几个字段（不希望新创建一个全新的身份验证类 subclassign AbstractBaseUser）

那我做错了什么？

Answer 1

解决方案

1. 要擦除，重新创建数据库
2. 删除 *.pyc 文件
3. 删除迁移文件夹

然后 python manage.py makemigrations 完美运行。
