Comment (by Charles Cunningham):
Replying to [comment:1 Mariusz Felisiak]:
> You cannot `Cast()` to `DecimalField`, or use it in `output_field`,
without providing `decimal_places` and `max_digits` arguments, e.g.
`DecimalField(decimal_places=2, max_digits=10)` works for me. Also, as far
as I'm aware there is no need to use `Cast()` in your case:
> {{{
> ...
> then=F("registration_volume") / F("capacity"),
> ...
> }}}
Wouldn't that result in integer division? Or if the output_field is
DecimalField, will it do decimal division?
