I would do something like this.
class Base(models.Model):
field1_base = models.IntegerField()
def initialize(self, *args, **kwargs):
self.field1_base = kwargs['field1_base']
@classmethod
def create(cls, *args, **kwargs):
# LOGICS
self = cls()
self.initialize(*args, **kwargs)
return self
class A(Base):
field2_sub = models.IntegerField()
def initialize(self, *args, **kwargs):
super(A, self).initialize(*args, **kwargs)
self.field2_sub = kwargs['field1_base']
A.create(field2_sub=1, field1_base=2)
