=head1 NAME

FS::quotation_pkg - Object methods for quotation_pkg records

=head1 SYNOPSIS

  use FS::quotation_pkg;

  $record = new FS::quotation_pkg \%hash;
  $record = new FS::quotation_pkg { 'column' => 'value' };

  $error = $record->insert;

  $error = $new_record->replace($old_record);

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::quotation_pkg object represents a quotation package.
FS::quotation_pkg inherits from FS::Record.  The following fields are currently
supported:

=over 4

=item quotationpkgnum

primary key

=item pkgpart

pkgpart

=item locationnum

locationnum

=item start_date

start_date

=item contract_end

contract_end

=item quantity

quantity

=item waive_setup

waive_setup

=head1 METHODS

=over 4

=item new HASHREF

Creates a new quotation package.  To add the quotation package 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.

sub table { 'quotation_pkg'; }

sub display_table         { 'quotation_pkg'; }

#forget it, just overriding cust_bill_pkg_display entirely
#sub display_table_orderby { 'quotationpkgnum'; } # something else?
#                                                 #  (for invoice display order)

sub discount_table        { 'quotation_pkg_discount'; }

=item insert

Adds this record to the database.  If there is an error, returns the error,
otherwise returns false.

=item delete

Delete this record from the database.

=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.

=item check

Checks all fields to make sure this is a valid quotation package.  If there is
an error, returns the error, otherwise returns false.  Called by the insert
and replace methods.

=item part_pkg_currency_option OPTIONNAME

Returns a two item list consisting of the currency of this quotation's customer
or prospect, if any, and a value for the provided option.  If the customer or
prospect has a currency, the value is the option value the given name and the
currency (see L<FS::part_pkg_currency>).  Otherwise, if the customer or
prospect has no currency, is the regular option value for the given name (see
L<FS::part_pkg_option>).
