FS::quotation - Object methods for quotation records

=head1 SYNOPSIS

  use FS::quotation;

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

  $error = $record->insert;

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

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

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

=over 4

=item quotationnum

primary key

=item prospectnum

prospectnum

=item custnum

custnum

=item _date

_date

=item disabled

disabled

=item usernum

=head1 METHODS

=over 4

=item new HASHREF

Creates a new quotation.  To add the quotation 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

sub table { 'quotation'; }
sub notice_name { 'Quotation'; }
sub template_conf { 'quotation_'; }

=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.  If there is
an error, returns the error, otherwise returns false.  Called by the insert
and replace methods.

link, and the second is the URL.

=item enable_previous

=item convert_cust_main

If this quotation already belongs to a customer, then returns that customer, as
an FS::cust_main object.

Otherwise, creates a new customer (FS::cust_main object and record, and
associated) based on this quotation's prospect, then orders this quotation's
packages as real packages for the customer.

If there is an error, returns an error message, otherwise, returns the
newly-created FS::cust_main object.

}

=item order

This method is for use with quotations which are already associated with a customer.

Orders this quotation's packages as real packages for the customer.

If there is an error, returns an error message, otherwise returns false.

=cut

sub order {
  my $self = shift;

  tie my %cust_pkg, 'Tie::RefHash',
    map { FS::cust_pkg->new({ pkgpart  => $_->pkgpart,

            => [] #services
        }
      $self->quotation_pkg ;

  $self->cust_main->order_pkgs( \%cust_pkg );

}

=item disable

Disables this quotation (sets disabled to Y, which hides the quotation on
prospects and customers).

If there is an error, returns an error message, otherwise returns false.

=cut

sub disable {
  my $self = shift;
  $self->disabled('Y');
  $self->replace();
}

=item enable

Enables this quotation.

If there is an error, returns an error message, otherwise returns false.

=cut

sub enable {
  my $self = shift;
  $self->disabled('');
