hi all

it does not seem to be possible to filter on the return value of a model's
method, or is it? are there alternative ways to achieve this?

my situation is as follows: there is a model with several child models (via
model inheritance). i want to retrieve in a single query set all instances
(from a parent/children tree) which match certain criteria using filter.
however, depending on the child model, the criteria vary. i tried to add a
method to the top-level model that is overridden in the inherited models in
order to return the proper boolean value. but using this method in a filter
does not work. any ideas?

thanks a lot for your help
