Hi Adam,
I have these two controllers whose code differs chiefly in respect of the
table being accessed.
The two tables (Affiliation and People) have a reciprocatory 'has_many' /
'belongs_to' relationship. While the affiliation_data sub works, the
people_data sub doesn't. The error message I'm getting for the people_data
sub inclines me to think that the 'allow_blessed' / 'convert_blessed'
features have to be enabled when a table has a 'belongs_to' relationship. I
don't know how to do that.
=head2 people_data
=cut
sub people_data : Local {
my ( $self, $c ) = @_;
my $rs = $c->model( 'AdventAjaxGrid2DB::People' );
my @people = ();
while ( my $person = $rs->next ) {
push( @people, {
id => $person->id,
name => $person->name,
affiliation_id => $person->affiliation_id,
} );
}
$c->stash->{ 'people_stash' } = \...@people;
$c->detach( $c->view( 'JSON' ) );
}
=head2 affiliation_data
=cut
sub affiliation_data : Local {
my ($self, $c) = @_;
my $rs = $c->model('AdventAjaxGrid2DB::Affiliation');
my @affiliations = ();
while (my $affiliation = $rs->next) {
push(@affiliations, {
affiliation_id => $affiliation->affiliation_id,
affiliation_name => $affiliation->affiliation_name
});
}
$c->stash->{'affiliation_stash'} = \...@affiliations;
$c->detach($c->view('JSON'));
}
