=head1 NAME

SL::DB::DeliveryOrder - Rose model for delivery orders (table
"delivery_orders")

=head1 FUNCTIONS

=over 4

=item C<date>

An alias for C<transdate> for compatibility with other sales/purchase models.

=item C<displayable_name>

Returns a human-readable and translated description of the delivery order, consisting of
record type and number, e.g. "Verkaufslieferschein 123".

=item C<displayable_state>

Returns a human-readable description of the state regarding being
closed and delivered.

=item C<items>

An alias for C<delivery_order_items> for compatibility with other
sales/purchase models.

=item C<new_from $source, %params>

Creates a new C<SL::DB::DeliveryOrder> instance and copies as much
information from C<$source> as possible. At the moment only instances
of C<SL::DB::Order> (sales quotations, sales orders, requests for
quotations and purchase orders) are supported as sources.

The conversion copies order items into delivery order items. Dates are copied
as appropriate, e.g. the C<transdate> field will be set to the current date.

Returns the new delivery order instance. The object returned is not
saved.

C<%params> can include the following options:

=over 2

=item C<items>

An optional array reference of RDBO instances for the items to use. If
missing then the method C<items_sorted> will be called on
C<$source>. This option can be used to override the sorting, to
exclude certain positions or to add additional ones.

=item C<skip_items_negative_qty>

If trueish then items with a negative quantity are skipped. Items with
a quantity of 0 are not affected by this option.

=item C<skip_items_zero_qty>

If trueish then items with a quantity of 0 are skipped.

=item C<item_filter>

An optional code reference that is called for each item with the item
as its sole parameter. Items for which the code reference returns a
falsish value will be skipped.

=item C<attributes>

An optional hash reference. If it exists then it is passed to C<new>
allowing the caller to set certain attributes for the new delivery
order.

=back

=item C<sales_order>

TODO: Describe sales_order

=item C<type>

Returns a string describing this record's type: either
C<sales_delivery_order> or C<purchase_delivery_order>.

=item C<convert_to_invoice %params>

Creates a new invoice with C<$self> as the basis by calling
L<SL::DB::Invoice::new_from>. That invoice is posted, and C<$self> is
linked to the new invoice via L<SL::DB::RecordLink>. C<$self>'s
C<closed> attribute is set to C<true>, and C<$self> is saved.

The arguments in C<%params> are passed to L<SL::DB::Invoice::new_from>.

Returns the new invoice instance on success and C<undef> on
failure. The whole process is run inside a transaction. On failure
nothing is created or changed in the database.

At the moment only sales delivery orders can be converted.
