Question

if I have table like this represented in django model

person
------
id
name

worker
------
personid
jobid

job
---
id
desc
wage

w=Worker.objects.filter(<some sort of filter)

now I want all persons that are related in w
w is given I can not use that statement.

eventually I want to return a json string that represents a dict
with idperson as key and {"job":jobid,"wage":wage} as
one value in list of jobs for that key
