Update a model field fetching data from user model in django - django

Question

I have a User model using AbstractBaseUser. I have a model Employee using Model class. I want that when a user is created though sign up, the user inherits all the fields of Employee model. I have made a OnetoOne relation between User model and Employee. But after creating an user when I query employee model, I can not find any data related to the created User.
User manager:
class UserManager(BaseUserManager):
"""
Creates and saves a User with the given email and password.
"""
def create_user(self, email, username, password=None):
if not email:
raise ValueError('Users must have an email address')
user = self.model(
email=self.normalize_email(email),
username=username
)
user.set_password(password)
user.save(using=self._db)
return user
def create_staffuser(self, email,username, password):
user = self.create_user(
email,
password=password,
username=username
)
user.is_staff = True
user.save(using=self._db)
return user
def create_superuser(self, email, username, password):
user = self.create_user(
email,
password=password,
username=username
)
user.is_staff = True
user.is_admin = True
user.save(using=self._db)
return user
User:
class User(AbstractBaseUser):
"""
Creates a customized database table for user
"""
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
)
username = models.CharField(max_length=255, unique=True)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_admin = models.BooleanField(default=False)
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email',]
objects = UserManager()
def get_full_name(self):
# The user is identified by their email address
return self.email
def get_short_name(self):
# The user is identified by their email address
return self.email
def __str__(self):
return self.email
def has_perm(self, perm, obj=None):
"Does the user have a specific permission?"
# Simplest possible answer: Yes, always
return True
def has_module_perms(self, app_label):
"Does the user have permissions to view the app `app_label`?"
# Simplest possible answer: Yes, always
return True
I have extended the user model with a OnetoOne relation using OneToOneField(User, on_delete=models.CASCADE, null=True)
Employee model:
class Employee(models.Model):
"""
Create employee attributes
"""
employee_user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
e_id = models.IntegerField(unique=True, null=False)
first_name = models.CharField(max_length=128)
last_name = models.CharField(max_length=128)
address = models.CharField(max_length=256, blank=True)
phone_number = models.CharField(max_length=128, blank=True)
email = models.EmailField(max_length=128, unique=True)
def get_absolute_url(self):
return reverse("employee:employee-list")
#receiver(post_save, sender=User)
def create_or_update_user_profile(sender, instance, created, **kwargs):
if created:
Employee.objects.create(employee_user=instance)
instance.Employee.save()
In this model there is also a field named email. I have to keep this field because I am using this model to create a form for Employee creation. But the problem is, User model's email field is conflicting with employee email field. I have to keep both the email fields.
Can I update the employee email field with user email field?? If yes, then what should be the query???

Answer 1

you have created a custom user model soo you need to import he Auth_User_model from you setting file and than use that not the django inbuilt auth User.
You can do this
from django.conf import settings
employee_user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
