DESCRIPTION

49       This component automatically removes "heavy-weight" columns.  To be
50       specific, columns of type "text", "ntext", "blob", "clob", or "bytea".
51       You may use the "remove_column" key in the column info to specify
52       directly whether or not to remove the column automatically. See "NOTE"
53       in DBIx::Class::Helper::ResultSet for a nice way to apply it to your
54       entire schema.
55

METHODS

57   _should_column_fetch
58        $self->_should_column_fetch('kitten')
59
60       returns true if a column should be fetched or not.  This fetches a
61       column if it is not of type "text", "ntext", "blob", "clob", or "bytea"
62       or the "remove_column" is set to true.  If you only wanted to
63       explicitly state which columns to remove you might override this method
64       like this:
65
66        sub _should_column_fetch {
67           my ( $self, $column ) = @_;
68
69           my $info = $self->column_info($column);
70
71           return !defined $info->{remove_column} || $info->{remove_column};
72        }
73
74   fetchable_columns
75       simply returns a list of columns that are fetchable.
