package FS::hardware_type;

=head1 NAME
FS::hardware_type - Object methods for hardware_type records
=head1 SYNOPSIS
use FS::hardware_type;
$record = new FS::hardware_type \%hash;
$record = new FS::hardware_type { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::hardware_type object represents a device type (a model name or
number) assignable as a hardware service (L<FS::svc_hardware>).
FS::hardware_type inherits from FS::Record. The following fields are
currently supported:
=over 4
=item typenum - primary key
=item classnum - key to an L<FS::hardware_class> record defining the class
to which this device type belongs.
=item model - descriptive model name or number
=item revision - revision name/number, subordinate to model
=back
=head1 METHODS
=over 4
=item new HASHREF
Creates a new record. To add the record to the database, see L<"insert">.
Note that this stores the hash reference, not a distinct copy of the hash it
points to. You can ask the object for a copy with the I<hash> method.
=cut
# the new method can be inherited from FS::Record, if a table method is defined
sub table { 'hardware_type'; }
=item insert
Adds this record to the database. If there is an error, returns the error,
otherwise returns false.
=cut
# the insert method can be inherited from FS::Record
=item delete
Delete this record from the database.
=cut
# the delete method can be inherited from FS::Record
=item replace OLD_RECORD
Replaces the OLD_RECORD with this one in the database. If there is an error,
returns the error, otherwise returns false.
=cut
# the replace method can be inherited from FS::Record
=item check
Checks all fields to make sure this is a valid hardware type. If there is
an error, returns the error, otherwise returns false. Called by the insert
and replace methods.
=cut
# the check method should currently be supplied - FS::Record contains some
# data checking routines
sub check {
my $self = shift;
my $error =
$self->ut_numbern('typenum')
|| $self->ut_foreign_key('classnum', 'hardware_class', 'classnum')
|| $self->ut_text('model')
|| $self->ut_textn('revision')
;
return $error if $error;
$self->SUPER::check;
}
=item hardware_class
Returns the L<FS::hardware_class> associated with this device.
=item description
Returns the model and revision number.
=cut
sub description {
my $self = shift;
$self->model . ($self->revision ? ' '.$self->revision : '');
}
=back
