How should I select rows from a join-model based on more than one association?
...more than one convention.
Also each workshop has a host, who is specific to a workshop being
held in a specific convention.
For example, Matz may host an "Introduction to Ruby" workshop in
RubyConf. And _why may host a the same workshop in RailsConf. This
operates through the join-model convention_workshops, which has the
following rows: convention_id, workshop_id, host_id, start_time. It
belongs_to :convention, :workshop, and :host.
Associations make it very easy to select by one association. If I want
to get the start_time of all workshops held on RubyConf Matz, I just
find RubyConf''s mode...
