DBIx::Class::Helper::RUserDContributed:PerleDocumenttSet::AutoRemoveColumns(3) 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.
