The accessor keyword tells your ORM to use an alternate name for the dual use get/set accessor for a field.
This is useful if you want to use the field's name for some other method.
I do this for date beautification,
among other things.
So,
as in the example below,
I might have a field like this:
field birth_day {
is date;
label `Birth Day`;
html_form_type text;
accessor birth_date_acc;
}
Then in the model stub for this table I can add a method called birth_date. Anyone calling it gets the formatting of my choosing:
sub birth_date {
my $row = shift;
my $value = $row->birth_date_acc( @_ );
return beautify_date( $value );
}
Note that I carefully dispatch to the real accessor first, then pretty up the date.

To see an example, build:
bigtop -c example.bigtop all
From the newly created Kids subdirectory, look in lib/Kids/Model/GEN/child.pm for a special add_columns statement for birth_day.
