Hi, All. Im new in DBIx::Class and this is my first question here :)

I write catalyst app and use dbic for 3 tables (males,females,family)  with has_many and may_to_many. All works, but there are too many requests to my database when i use this: 

 my $rs = $c->model('AppModelDB::ClientMale')->search();

while (my $line = $rs->next) {

            push @{$families},[ $line->client_family->first->id,

                     make_family(

                                 $line->first_n, 

                                 $line->family_n,

                                 $line->client_female->first->first_n,

                                 $line->client_female->first->family_n 

                                )

                ,$line->client_family->first->city

                ,$line->client_family->first->zip_code

                ,$line->client_family->first->municipality 

                ,$line->client_family->first->street

                ,$line->client_family->first->public_place_type

                ,$line->client_family->first->public_place_name

                ];

        }

}

$c->stash->{families} = $families;


I wrote "export DBIC_TRACE=1" for debug and saw alot of screens with SELECT requests to MySQL. Plese help me to optimize the code. Every single table has around 190 lines. 

Thank you



Use 'join' or 'prefetch' attribute for search. Also see the Cookbook http://search.cpan.org/~ash/DBIx-Class-0.08008/lib/DBIx/Class/Manual/Cookbook.pod#JOINS_AND_PREFETCHING
