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.
