I am working on a django project which requires login through email or phone number. This is my models.py file:
class NewUser(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(_('email address'), unique=True)
username = models.CharField(max_length=150, blank=True, unique=True)
first_name = models.CharField(max_length=150, blank=True)
phone_regex = RegexValidator(regex =r'^\+?1?\d{9,14}$', message="Phone number must be in the format: '+999999999'. Upto 14 digita allowed.")
phone = models.CharField(validators=[phone_regex], max_length=15, unique=True)
first_login = models.BooleanField(default=False)
start_date = models.DateTimeField(default=timezone.now)
about = models.TextField(_(
'about'), max_length=500, blank=True)
is_staff = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
#objects = CustomAccountManager()
#objects = EmailOrPhoneModelBackend()
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = []
def __str__(self):
return self.username
def get_email_field_name(self):
if self.email:
return self.email
else:
return self.phone
def has_perm(self, perm, obj=None):
return True
def has_module_perms(self, app_label):
return True
@property
def is_active(self):
return self.is_active
@property
def is_staff(self):
return self.is_staff
@property
def is_admin(self):
return self.is_admin
To authenticate by using both email and phone number I have created a custom authentication file - backends.py
class EmailOrPhoneModelBackend(ModelBackend):
#This is a ModelBacked that allows authentication with either a username or an email address.
def authenticate(self, username= None, password=None, **kwargs):
if '@' in username:
kwargs = {'email': username}
elif re.search("^0?[5-9]{1}\d{9}$",username): #optional
kwargs = {'phone':username}
try:
user = NewUser.objects.get(**kwargs)
if user.check_password(password):
return user
except NewUser.DoesNotExist:
return None
def get_user(self, user_id): #username replaced with id
try:
return NewUser.objects.get(pk = user_id)
except NewUser.DoesNotExist:
return None
and I have modified my settings accordingly as :
AUTH_USER_MODEL = "adminUser.NewUser"
AUTHENTICATION_BACKENDS = ['adminUser.backends.EmailOrPhoneModelBackend',
'django.contrib.auth.backends.ModelBackend',]
However, when I try to make the migrations I am getting the following error:
AUTH_USER_MODEL refers to model 'adminUser.NewUser' that has not been installed
I have added the app 'adminUser' in the list of INSTALLED_APPS in settings.py also. I have also gone through the similar questions asked earlier but none of them have helped. Am not sure what is causing the issue and how it can be resolved. Thanks for your time in advance.
Below is the full stack trace of the error I am facing:

In the traceback you can see the following lines:
File "C:\Users\DELL\Documents\AysleAdmin\adminPanel\adminUser\models.py", line 20, in <module>
from .backends import EmailOrPhoneModelBackend
This means you import the backend in models.py for some reason (doesn't make sense the backend shouldn't be needed here). Next in the backend you also use NewUser which implies that it also imports NewUser, this essentially means both files try to import the other leading to a circular import issue (In the end you model doesn't end up getting loaded).
The solution is simply to remove the line from .backends import EmailOrPhoneModelBackend from models.py.
