[Pas-dev] Another Propsal - Parameter Maps?

[Kyle R . B. <mo...@vo...>]

package Com::Domain::Site::AccountSetup;
use strict;
use warnings;
use Org::Bgw::Pas::Page;
our @ISA = qw( Org::Bgw::Pas::Page );

Com::Domain::Site::AccountSetup->buildRequestParameterMap(
  'first_name' => 'firstName',
  'last_name'  => 'lastName',
  'middle'     => 'middleName',
);
# buildRequestParameterMap would do a few things, first it would use the 
# values of the passed pairs and effectivly call:
#  Com::Domain::Site::AccountSetup->makeGetSetMethods(qw( firstName lastName ));
# for you.  Second, it sets up a method (that will be called from 
# SUPER::request_init that moves parameters from the request object into
# your object's get/set methods.

sub execute
{
  my($self) = @_;
  # now just use the params!  they're already available in your get/set
  # methods
}

# extension 1, allow for 'scurbbing' or mutating to take place:
#
Com::Domain::Site::AccountSetup->buildRequestParameterMap(
  'first_name' => { 'slot' => 'firstName',  'mutator' => 'scrubName' },
  'last_name'  => { 'slot' => 'lastName',   'mutator' => 'scrubName' },
  'middle'     => { 'slot' => 'middleName', 'mutator' => 'scrubName' },
);

# this gets called for each defined param that has this method
# as it's mutator - then the data returned by this method is
# assigned to the appropriate get/set method (which again are
# automatically created based on the 'slot' values from the mapping).
sub scrubName
{
  my($self,$data) = @_;
  $data =~ s/\d+//;
  return $data;
}

sub execute
{
  my($self) = @_;
  # now just use the params!  they're already available in your get/set
  # methods, and they've been passed through the scrubbing methods
}
