I have a model

```
class ItemPrice( models.Model ):
price = models.DecimalField ( max_digits = 8, decimal_places=2 )
....
```

I tried this to calculate the sum of `price`

in this queryset:

```
items = ItemPrice.objects.all().annotate(Sum('price'))
```

what’s wrong in this query? or is there any other way to calculate the Sum of `price`

column?

I know this can be done by using for loop on queryset but i need an elegant solution.

Thanks!
