I have a complicated query which should return the subset of a table whose objects match one of several conditions.
What's the easiest way of doing this, given that I can't just do a SQL statement, because some of the conditions require me to feed the object's values into a function to evaluate it. I've had a few ideas: a) Pulling back the entire table, and deleting from the query set those objects which don't match. Is this possible? I get the feeling that using delete() would delete the entry from the db, which i don't want to do. b) Doing multiple querysets and making a union out of the results. I can't find any documentation to show how to union 2 querysets - is it possible? c) Writing a custom Manager.
