[Dbix-class] Related results, prefetch, paging = problem

[Mark Blythe]

Sorry, my mistake.  I missed one change in the example.  You should
use 'select' instead of 'columns'.  At least I did:

$c->stash->{routes} = $c->model('QDB::Routes')->search(
                  {
                          'me.net_id'    => $c->stash->{net_id},
                          'me.route_beg' => $c->stash->{node_id_beg},
                          'me.route_end' => $c->stash->{node_id_end},
                  },
                  {
                          join => { 'xc_params' => 'nodes' },

                          select  => [qw/
                          me.route_id me.route_beg me.route_end
me.err_code me.comment me.net_id
                          xc_params.node_rank xc_params.ch_beg xc_params.ch_end
                          nodes.node_id nodes.node_name
                          / ],

                          as  => [qw/
                          route_id route_beg route_end err_code comment net_id
                          xc_params.node_rank xc_params.ch_beg xc_params.ch_end
                          xc_params.nodes.node_id xc_params.nodes.node_name
                          / ],

                          #TODO Paged output
                          order_by => [ @order_by ],
                          page     => $page,       # page to return
(defaults to 1)
                          rows     => $rows,       # number of results per page,
                          cache => 1
                  }
          );
