I have 3 tables:
pupils:           id, name, born_date, sex
courses:        id, course_name, description
pupilXcourse: pupil_id, course_id

Today I run a Pupil.find(:all) and send a json response to the
browser, who shows a table of pupils and its attributes.
I want to include in this listing on the browser a field showing what
courses each pupil got.
I don`t know the fast/easy method to achieve this. Maybe a custom,
more complex, select statment, or a additional select with additional
json request.

If you have hints or examples, it you be very welcome.



Thank you!
