I have the below Django ORM which represents a PostgreSQL view.

For the field cost_requirement I have set the default value to 0. However the queryset object still populates with None if data is missing for this field.

I have made all migrations and I just want the default to apply at the Python side (nothing to do with the database). From the Django documentation I understand I am using this argument correctly.

Any suggestions why the default value of 0 is not being applied?

class DashboardProduct(models.Model):
    date = models.DateField()
    product_id = models.CharField(max_length=50)
    base_l = models.FloatField(default=0)   
    cost_requirement =  models.FloatField(blank=False, null=False, default=0)
    book = models.CharField(max_length=100, blank=True, null=True)
    portfolio = models.CharField(max_length=100, blank=True, null=True)
    sales_5_pnl = models.FloatField(default=0)   
    

    class Meta: 
        managed = False 
        db_table = 'view_dashboard_product'
