Hi there,
If every "Client" object as a 0 or more "Trip" objects as described
here:
class Client
has n, :tripClients
has n, :trips, :through => :tripClients
...
end
What the best syntax for finding all clients that share Trips with a
given client?
The best I've come up with so far is:
def fellowTravellers(client)
return Client.all( Client.trips.trip_id => client.trips.map{ |
trip| trip.id } )
end
It seems to work but it does not make good use of datamapper's
cleverness (and it runs 2 queries)
Many thanks
