> Also, you don't need to use `extra()` you can use a custom function (if
it already exists in your db):
> {{{
> class CastToNumeric(Func):
> function = 'cast_to_numeric'
> output_field = FloatField()
> }}}
Pardon my ignorance for reopening closed tickets. This suggestion is
indeed of great help. Thank you.
