DESCRIPTION

This component is meant to be a more powerful, but less DWIM-y, DBIx::Class::InflateColumn. One of the major issues with said component is that it only works with references. Generally speaking anything that can be done with DBIx::Class::InflateColumn can be done with this component.

METHODS

filter_column

 __PACKAGE__->filter_column( colname => {
     filter_from_storage => 'method',

This is the method that you need to call to set up a filtered column.
