use POSIX qw(strcoll);
=head1 Name
FixMyStreet::DB::ResultSet::Body - a ResultSet class for the Body model.
=head1 Synopsis
my @bodies = $rs->for_areas(1, 2)->active->with_area_count->translated->all_sorted;
=head1 Functions
=over
=item for_areas
This restricts the ResultSet to bodies covering the area IDs provided.
=cut
sub for_areas {
my ( $rs, @areas ) = @_;
my $result = $rs->search(
{ 'body_areas.area_id' => \@areas },
{ join => 'body_areas' }
);
return $result;
}
=item active
This restricts the ResultSet to bodies that are not marked as deleted.
=cut
sub active {
my $rs = shift;
$rs->search({ 'me.deleted' => 0 });
}
=item translated
This joins the ResultSet to the translation table, adding the `msgstr`
column containing possible translations of the body name.
=cut
sub translated {
my $rs = shift;
my $schema = $rs->result_source->schema;
$rs->search(undef, {
'+columns' => { 'msgstr' => 'translations.msgstr' },
join => 'translations',
bind => [ 'name', $schema->lang, 'body' ],
});
}
=item with_parent_name
This adds the parent name associated with each body to the ResultSet,
in the parent_name column.
=cut
sub with_parent_name {
my $rs = shift;
$rs->search(undef, {
'+select' => [ 'parent.name' ],
'+as' => [ 'parent_name' ],
join => 'parent',
});
}
=item with_area_count
This adds the number of areas associated with each body to the ResultSet,
in the area_count column.
=cut
sub with_area_count {
my $rs = shift;
$rs->search(undef, {
'+select' => [ { count => 'area_id' } ],
'+as' => [ 'area_count' ],
join => 'body_areas',
distinct => 1,
});
}
=item with_defect_type_count
This adds the number of defect types associated with each body to the
ResultSet, in the defect_type_count column.
=cut
sub with_defect_type_count {
my $rs = shift;
$rs->search(undef, {
'+select' => [ { count => 'defect_types.name' } ],
'+as' => [ 'defect_type_count' ],
join => 'defect_types',
distinct => 1,
});
}
=item with_children_count
This adds the number of children associated with each body to the
ResultSet, in the children_count column.
=cut
sub with_children_count {
my $rs = shift;
$rs->search(undef, {
'+select' => [ { count => 'bodies.id' } ],
'+as' => [ 'children_count' ],
join => 'bodies',
distinct => 1,
});
}
=item all_sorted
This returns all results, as C<all()>, but sorted by their name (including
the translated names, if present), and as simple hashrefs not objects, for
performance reasons.
=back
=cut
sub all_sorted {
my $rs = shift;
# Use a HashRefInflator here to return simple hashrefs rather than full
# objects. This is quicker if you have a large number of bodies; note
# fetching only the columns you need provides even more of a speed up.
my @bodies = $rs->search(undef, {
result_class => 'DBIx::Class::ResultClass::HashRefInflator',
})->all;
@bodies = sort { strcoll($a->{msgstr} || $a->{name}, $b->{msgstr} || $b->{name}) } @bodies;
my $cobrand = $rs->result_source->schema->cobrand;
foreach my $body (@bodies) {
$body->{parent} = { id => $body->{parent}, name => $body->{parent_name} } if $body->{parent};
# DEPRECATED: url(c, query_params) -> url
$body->{url} = sub {
my ($c, $args) = @_;
return FixMyStreet::DB::Result::Body::_url($body, $cobrand, $args);
};
# DEPRECATED: get_column('area_count') -> area_count
next unless defined $body->{area_count};
$body->{get_column} = sub {
my $key = shift;
return $body->{$key};
};
}
return @bodies;
