=head1 NAME
Package WebGUI::Shop::ShipDriver
=head1 DESCRIPTION
This package is the base class for all modules which calculate shipping
costs.
=head1 SYNOPSIS
use WebGUI::Shop::ShipDriver;
my $tax = WebGUI::Shop::ShipDriver->new($session);
=head1 METHODS
These subroutines are available from this package:
=cut
readonly session => my %session;
private options => my %options;
private shipperId => my %shipperId;
#-------------------------------------------------------------------
=head2 calculate ( )
This method calculates how much it costs to ship the contents of a cart. This method
MUST be overridden in all child classes.
=cut
sub calculate {
croak "You must override the calculate method";
}
#-------------------------------------------------------------------
=head2 create ( $session, $options )
Constructor for new WebGUI::Shop::ShipperDriver objects. Returns a WebGUI::Shop::ShipperDriver object.
To access driver objects that have already been configured, use C<new>.
=head3 $session
A WebGUI::Session object.
=head4 $options
A list of properties to assign to this ShipperDriver. See C<definition> for details.
=cut
sub create {
my $class = shift;
my $session = shift;
WebGUI::Error::InvalidParam->throw(error => q{Must provide a session variable})
unless ref $session eq 'WebGUI::Session';
my $options = shift;
WebGUI::Error::InvalidParam->throw(error => q{Must provide a hashref of options})
unless ref $options eq 'HASH' and scalar keys %{ $options };
my $shipperId = $session->id->generate;
$session->db->write('insert into shipper (shipperId,className) VALUES (?,?)', [$shipperId, $class]);
my $self = $class->new($session, $shipperId);
$self->update($options);
return $self;
}
#-------------------------------------------------------------------
=head2 definition ( $session )
This subroutine returns an arrayref of hashrefs, used to validate data put into
the object by the user, and to automatically generate the edit form to show
the user.
=cut
sub definition {
my $class = shift;
my $session = shift;
WebGUI::Error::InvalidParam->throw(error => q{Must provide a session variable})
unless ref $session eq 'WebGUI::Session';
my $definition = shift || [];

tie my %fields, 'Tie::IxHash';
%fields = (
label => {
fieldType => 'text',
label => $i18n->get('label'),
hoverHelp => $i18n->get('label help'),
defaultValue => undef,
},
enabled => {
fieldType => 'yesNo',
label => $i18n->get('enabled'),

defaultValue => 1,
},
);
my %properties = (
name => 'Shipper Driver',
properties => \%fields,
);
push @{ $definition }, \%properties;

}
#-------------------------------------------------------------------
=head2 delete ( )
Removes this ShipDriver object from the db.
=cut
sub delete {
my $self = shift;
$self->session->db->write('delete from shipper where shipperId=?',[$self->getId]);
return;
}
#-------------------------------------------------------------------
=head2 get ( [ $param ] )
This is an enhanced accessor for the options property. By default,
it returns all the options as a hashref. If the name of a key
in the hash is passed, it will only return that value from the
options hash.
=head3 $param
An optional parameter. If it matches the key of a hash, it will
return the value from the options hash.
=cut
sub get {
my $self = shift;
my $param = shift;
my $opts = $options{id $self};
if ($opts eq "") {
$opts = {};
}
else {

}

}
my %copy = %{$opts};
return \%copy;
}
#-------------------------------------------------------------------
=head2 getEditForm ( )
Dynamically generate an HTMLForm based on the contents
of the definition sub, and return the form.
=cut
sub getEditForm {
my $self = shift;
my $definition = $self->definition($self->session);
my $form = WebGUI::HTMLForm->new($self->session);

$form->hidden(name => 'do',value => "editSave");
$form->dynamicForm($definition, 'properties', $self);
return $form;
}
#-------------------------------------------------------------------
=head2 getId ( )
Returns the shipperId. This is an alias for shipperId provided
since a lot of WebGUI classes have a getId method.
=cut
sub getId {
my $self = shift;
return $shipperId{id $self};
}
#-------------------------------------------------------------------
=head2 getName ( $session )
Return a human readable name for this driver. Never overridden in the
subclass, instead specified in definition with the name "name".
This is a class method.
=cut
sub getName {
my ($class, $session) = @_;
my $definition = $class->definition($session);
return $definition->[0]->{name};
}
#-------------------------------------------------------------------
=head2 new ( $session, $shipperId )
Looks up an existing ShipperDriver in the db by shipperId and returns
that object.
=cut

#-------------------------------------------------------------------
=head2 processPropertiesFromFormPost ( )
Updates ship driver with data from Form.
=cut
sub processPropertiesFromFormPost {
my $self = shift;
my %properties;
my $fullDefinition = $self->definition($self->session);
foreach my $definition (@{$fullDefinition}) {

#-------------------------------------------------------------------
=head2 session ( )
Accessor for the session object. Returns the session object.
=cut
#-------------------------------------------------------------------
=head2 update ( $options )
Setter for user configurable options in the ship objects.
=head4 $options
A list of properties to assign to this ShipperDriver. See C<definition> for details. The options are
flattened into JSON and stored in the database as text. There is no content checking performed.
=cut
sub update {
my $self = shift;

=head2 www_edit ( )
Generates an edit form.

Saves the data from the post.
