NAME¶
DBIx::Class::Helper::ResultSet::AutoRemoveColumns - Automatically remove columns
from a ResultSet
SYNOPSIS¶
package MySchema::Result::Bar;
use strict;
use warnings;
use parent 'DBIx::Class::Core';
__PACKAGE__->table('KittenRobot');
__PACKAGE__->add_columns(
id => {
data_type => 'integer',
is_auto_increment => 1,
},
kitten => {
data_type => 'integer',
},
robot => {
data_type => 'text',
is_nullable => 1,
},
your_mom => {
data_type => 'blob',
is_nullable => 1,
remove_column => 0,
},
);
1;
package MySchema::ResultSet::Bar;
use strict;
use warnings;
use parent 'DBIx::Class::ResultSet';
__PACKAGE__->load_components('Helper::ResultSet::AutoRemoveColumns');
DESCRIPTION¶
This component automatically removes "heavy-weight" columns. To be
specific, columns of type "text", "ntext",
"blob", "clob", or "bytea". You may use the
"remove_column" key in the column info to specify directly whether
or not to remove the column automatically. See "NOTE" in
DBIx::Class::Helper::ResultSet for a nice way to apply it to your entire
schema.
METHODS¶
_should_column_fetch¶
$self->_should_column_fetch('kitten')
returns true if a column should be fetched or not. This fetches a column if it
is not of type "text", "ntext", "blob",
"clob", or "bytea" or the "remove_column" is set
to true. If you only wanted to explicitly state which columns to remove you
might override this method like this:
sub _should_column_fetch {
my ( $self, $column ) = @_;
my $info = $self->column_info($column);
return !defined $info->{remove_column} || $info->{remove_column};
}
fetchable_columns¶
simply returns a list of columns that are fetchable.
