Django multi-table inheritance, how to know which is the child class of a model?

Question

I\'m having a problem with multi-table inheritance in django.

Let’s make an example with bank accounts.

class account(models.Model):
    name = models……         


        

Answer 1

To the best of my knowledge there isn't a Django built-in way to do this.

However, given acc=account.object.get(pk=29), you can use:

try:
    typeA = acc.accounttypeA
    # acc is typeA
except accounttypeA.DoesNotExist:
    # acc should be typeB if account only has typeA and typeB subclasses

try:
    typeB = acc.accounttypeB
    # acc is typeB
except accounttypeB.DoesNotExist:
    # acc should be typeA if account only has typeA and typeB subclasses
