You don’t need a second Transaction
class in your views. It is shadowing the Transaction
model/class imported from your model. Remove it!
More so, you also don’t need a custom sum function, use the builtin sum
:
def index(request):
transactions = Transaction.objects.all()
balance = sum(t.amount if t.name=='deposit' else -t.amount for t in transactions)

The Transaction
class that you have in your views.py
file shadows your Transaction
model.
Transaction
in views.py
file is a simple python class (not a Django model), to fix your issue, you need to remove it from views.py
