There are tables Product and Transaction. In Product admin there is a field
that shows how many transactions have been created with this product.
Now, I want to filter the period of time in which these transactions were
created. For example, there was 30 transactions in the last week, but 100
in the last month.
class Transaction(models.Model):
created = models.DateTimeField()
product = models.ForeignKey('Product')
class Product(models.Model):
name = models.CharField()
def num_of_trans(self):
return
Transaction.objects.filter(created="""DATE_VALUE_HERE""").filter(product=self.id).count()
I tried to adjust the queryset in a class that extends SimpleListFilter,
however I did not manage to make it work.
Another thing I thought of was to add an additional parameter to
num_of_trans function, but it seems there is not way to pass this parameter
while using the filter.
I would appreciate any tips.
