should history models have a type in django?

Here is my code in Django:

class DeductRecord(models.Model):
    userid = models.IntegerField()
    total_amount = models.IntegerField()
    type = models.IntegerField(choices=...)

class DeductHistoryA(models.Model):
    deduct_record = ForeignKey(DeductRecord)
    amount = models.IntegerField()

The code above is a function for deducting money. DeductRecord is to record total deduct amount, DeductHistory is to record deduct history every day.

DeductRecord have vary type, I could distinguish different DeductHistory type by foreign key deduct_record, but database would query twice if I want to know a DeductHistory instance's type.

Here is DeductHistoryB with type:

class DeductHistoryB(models.Model):
    deduct_record = ForeignKey(DeductRecord)
    amount = models.IntegerField()
    type = models.IntegerField(choices=...)

I can know DeductHistory's type without query twice, but I should guarantee the type between DeductHistory and DeductRecord. I want to know, which is the best way if I want to distinguish different DeductHistory's type.
