Parsing integerfields as integer values

I'm looking for a way to parse the value of integerFields and returning the value.

scoreChans = models.IntegerField(0)
scoreChansSet = models.BooleanField(False)
scoreYatzy = models.IntegerField(0)
scoreYatzySet = models.BooleanField(False) 

scoreTotal = scoreChans + scoreYatzy

But this gives: TypeError: unsupported operand type(s) for +: 'IntegerField' and 'IntegerField'

Is there a way the fetch the values from these fields?

You can only fetch the values on an instantiated model.

I assume you want to have a computed property? Something like:

class MyModel(models.Model):
    score_a = models.IntegerField()
    score_b = models.IntegerField()

    @property
    def total_score(self):
        return self.score_a + self.score_b
