Hi,I have a Django IntegerField that I'm using to store the purchase limit for a product. purchase_limit = models.IntegerField() I also need to represent no limit (i.e. infinity) as well in that field. I was thinking of just using NULL to represent no limit. purchase_limit = models.IntegerField(blank=True, null=True)
If there is a purchase limit put it in. Otherwise there is no purchase limit. For me, None/Null would be comfortable. But I might be tempted to add functions in the model's clean() method which encapsulate the the business rules for the app - whatever they are.
Zero would have a meaning for this field (you can't buy any), however negative numbers don't have any meaning. Hence, another option is just to use say, -1 as the value to represent no limit. Any thoughts on either option, or which one is more "correct"? Cheers, Victor -- You received this message because you are subscribed to the Google Groups "Django users" group.
