Django Error help!?

I having an Error in a Django project while making migrations: ValueError: Related model 'home.account' cannot be resolved

This is my settings.py

models.py:

class AccountManager(PermissionsMixin): object = BaseUserManager() class Meta: abstract = True def create_user(self, username, email, password=None): if username is None: raise TypeError('Username cannot be empty') if email is None: raise TypeError('Email cannot be empty') user = self.model(username=username, email=self.normalize_email(email)) user.set_password(password) user.save() return user def create_super_user(self, username, email, password=None): if password is None: raise TypeError('Password cannot be empty') user = self.create_user(username, email, password) user.is_super_user = True user.is_admin = True user.save() return user class Account(AbstractBaseUser): username = models.CharField('settings.AUTH_USER_MODEL', max_length=300, unique=True) email = models.EmailField(max_length=300, unique=True) is_verified = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) # only for superuser created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['username'] objects = AccountManager def __str__(self): return self.email def tokens(self): return '' 

view.py:
