Django model id turns into a tuple - django

Question

I have a super class for my models as below:
class BaseModel(models.Model):
""" BaseClass vase aksare model ha """
def __init__(self, *args, **kwargs):
super(BaseModel, self).__init__(args, kwargs)
print('******> base model __init__')
status = models.IntegerField(default=1)
is_deleted = models.BooleanField(default=False)
create_user = models.ForeignKey(User, related_name="%(app_label)s_%(class)s_creator_related")
create_date = models.DateTimeField()
update_date = models.DateTimeField()
update_user = models.ForeignKey(User, related_name="%(app_label)s_%(class)s_updater_related")
class Meta:
abstract = True
def validate(self):
print('^^^^^^^^^^^^^^^^^^^^^^^^^^^^base validation')
and I have a profile model as below:
class Profile(BaseModel):
def __init__(self, *args, **kwargs):
super(Profile, self).__init__(args, kwargs)
""" User profile """
user = models.OneToOneField(User, related_name='profile')
mobile = models.CharField(max_length=25, null=True)
firstname_en = models.CharField(max_length=500, null=True)
lastname_en = models.CharField(max_length=500, null=True)
gender = models.IntegerField(default=0)
birth_date = models.DateTimeField(null=True)
edu_bg = models.ForeignKey('Category', related_name="profile__edu_bg", null=True)
region = models.ForeignKey('Category', related_name="profile__region", null=True)
credit = models.DecimalField(default=0, decimal_places=6, max_digits=15)
key = models.TextField(null=True)
secret = models.TextField(null=True)
I have an error when I want to insert a new userProfile as below:
TypeError: int() argument must be a string, a bytes-like object or a number, not 'tuple'.
then print the vars(userprofileObject) and realized that 'id': ((), {}), however, I have not set it. When I removed the __init__ functions or set id to None in insertion code, problem solved.
Any idea?
I need those __init__ and also don't want to set id=None in my code

This is how django's models work. You shouldn't change their __init__ method.
This is why
You may be tempted to customize the model by overriding the __init__ method. If you do so, however, take care not to change the calling signature as any change may prevent the model instance from being saved. Rather than overriding __init__, try using one of these approaches:
# Add a classmethod on the model class:
from django.db import models
class Book(models.Model):
title = models.CharField(max_length=100)
#classmethod
def create(cls, title):
book = cls(title=title)
# do something with the book
return book
book = Book.create("Pride and Prejudice")
