How can I determine if instance of class from Django model is subclass of another model?
django, django-models, inheritance, python, subclass
Solution
Try to use the `checkingaccount` and `savingsaccount` attributes. The one it is will not blow up.
Problem
I have a class called `BankAccount` as base class. I also have `CheckingAccount` and `SavingsAccount` classes that inherit from `BankAccount`. BankAccount is not an abstract class but I do not create an object from it, only the inheriting classes. Then, I execute a query like this: ``` account = BankAccount.objects.get(id=10) ``` How do I know if account is `CheckingAccount` or `SavingsAccount`? The way I do this now is in this way: ``` checking_account = CheckingAccount.objects.get(id=account.id) ``` If it exists, it is a `CheckingAccount`, otherwise, it is a `SavingsAccount`.
