+
+DBIx::Class::Positioned - Modify the position of objects in an ordered list.
+
+=head1 SYNOPSIS
+
+Create a table for your positionable data.
+
+ CREATE TABLE employees (
+ employee_id INTEGER PRIMARY KEY AUTOINCREMENT,
+ name TEXT NOT NULL,
+ position INTEGER NOT NULL
+ );
+
+In your Schema or DB class add Positioned to the top
+of the component list.
+
+ __PACKAGE__->load_components(qw( Positioned ... ));
+
+Specify the column that stores the position number for
+each row.
+
+ package My::Employee;
+ __PACKAGE__->position_column('position');
+
+Thats it, now you can change the position of your objects.

+=head1 DESCRIPTION
+
+This module provides a simple interface for modifying the position
+of DBIx::Class objects.
+
+=head1 AUTO UPDATE
+
+All of the move_* methods automatically update the rows involved in
+the query. This is not configurable and is due to the fact that if you
+move a record it always causes other records in the list to be updated.
+
+=head1 METHODS
+
+=head2 position_column
+
+ __PACKAGE__->position_column('position');
+
+Sets and retrieves the name of the column that stores the
+positional value of each record. Default to "position".
+
+=cut
+
+__PACKAGE__->mk_classdata( 'position_column' => 'position' );
+
+=head2 collection_column
+
+ __PACKAGE__->collection_column('thing_id');
+
+This method specified a column to limit all queries in
+this module by. This effectively allows you to have multiple
+positioned lists within the same table.
+
+=cut
+
+__PACKAGE__->mk_classdata( 'collection_column' );
+
+=head2 siblings
+
+ my $rs = $employee->siblings();
+ my @siblings = $employee->siblings();
+
+Returns either a result set or an array of all other objects
+excluding the one you called it on.
+
+=cut
+
+sub siblings {
+ my( $self ) = @_;
+ my $position_column = $self->position_column;
+ my $rs = $self->result_source->resultset->search(
+ {
+ $position_column => { '!=' => $self->get_column($position_column) },
+ $self->_collection_clause(),
+ },
+ { order_by => $self->position_column },
+ );
+ return $rs->all() if (wantarray());
+ return $rs;
+}
+
+=head2 first_sibling
+
+ my $sibling = $employee->first_sibling();
+
+Returns the first sibling object.

+ return ($self->result_source->resultset->search(
+ {
+ $self->position_column => 1,
+ $self->_collection_clause(),
+ },
+ )->all())[0];
+}
+
+=head2 last_sibling
+
+ my $sibling = $employee->last_sibling();
+
+Return the last sibling.
+
+=cut
+
+sub last_sibling {
+ my( $self ) = @_;

+ $self->_collection_clause(),
+ },
+ )->all())[0];
+}
+
+=head2 previous_sibling
+
+ my $sibling = $employee->previous_sibling();
+
+Returns the sibling that resides one position higher. Undef
+is returned if the current object is the first one.
+
+=cut
+

+ $self->_collection_clause(),
+ }
+ )->all())[0];
+}
+
+=head2 next_sibling
+
+ my $sibling = $employee->next_sibling();
+
+Returns the sibling that resides one position lower. Undef
+is returned if the current object is the last one.
+
+=cut
+
+sub next_sibling {

+ $self->_collection_clause(),
+ },
+ )->all())[0];
+}
+
+=head2 move_previous
+
+ $employee->move_previous();
+
+Swaps position with the sibling on position previous in the list.
+1 is returned on success, and 0 is returned if the objects is already
+the first one.
+
+=cut
+
+sub move_previous {
+ my( $self ) = @_;
+ my $position = $self->get_column( $self->position_column() );
+ return $self->move_to( $position - 1 );
+}
+
+=head2 move_next
+
+ $employee->move_next();
+
+Swaps position with the sibling in the next position. 1 is returned on
+success, and 0 is returned if the object is already the last in the list.
+
+=cut

+ return 0 if ($position==$count);
+ return $self->move_to( $position + 1 );
+}
+
+=head2 move_first
+
+ $employee->move_first();
+
+Moves the object to the first position. 1 is returned on
+success, and 0 is returned if the object is already the first.

+=cut
+
+sub move_first {
+ my( $self ) = @_;
+ return $self->move_to( 1 );
+}
+
+=head2 move_last
+
+ $employee->move_last();
+
+Moves the object to the very last position. 1 is returned on
+success, and 0 is returned if the object is already the last one.

+
+=head2 move_to
+
+ $employee->move_to( $position );

+ $position_column => { ($from_position>$to_position?'>=':'<=') => $to_position },
+ ],

+ $position_column => \"$position_column $op 1",
+ });
+ $self->set_column( $position_column => $to_position );
+ $self->update();
+ return 1;
+}
+
+=head2 insert
+
+Overrides the DBIC insert() method by providing a default
+position number. The default will be the number of rows in
+the table +1, thus positioning the new record at the last position.
+
+=cut
+
+sub insert {
+ my $self = shift;
+ my $position_column = $self->position_column;
+ $self->set_column( $position_column => $self->result_source->resultset->search( {$self->_collection_clause()} )->count()+1 )
+ if (!$self->get_column($position_column));
+ $self->next::method( @_ );
+}
+
+=head2 delete
+
+Overrides the DBIC delete() method by first moving the object
+to the last position, then deleting it, thus ensuring the
+integrity of the positions.
+
+=cut
+
+sub delete {
+ my $self = shift;
+ $self->move_last;
+ $self->next::method( @_ );
+}
+
+=head1 PRIVATE METHODS
+
+These methods are used internally. You should never have the
+need to use them.
+
+=head2 _collection_clause
+
+This method returns a name=>value pare for limiting a search
+by the collection column. If the collection column is not
+defined then this will return an empty list.
+
+=cut
+
+sub _collection_clause {
+ my $self = shift;
+ if ($self->collection_column()) {
+ return ( $self->collection_column() => $self->get_column($self->collection_column()) );
+ }
+ return ();
+}
+
+1;
+__END__
+
+=head1 BUGS
+
+=head2 Race Condition on Insert
+
+If a position is not specified for an insert than a position
+will be chosen based on COUNT(*)+1. But, it first selects the
+count then inserts the record. The space of time between select
+and insert introduces a race condition. To fix this we need the
+ability to lock tables in DBIC. I've added an entry in the TODO
+about this.
+
+=head2 Multiple Moves
+
+Be careful when issueing move_* methods to multiple objects. If
+you've pre-loaded the objects then when you move one of the objects
+the position of the other object will not reflect their new value
+until you reload them from the database.
+
+The are times when you will want to move objects as groups, such
+as changeing the parent of several objects at once - this directly
+conflicts with this problem. One solution is for us to write a
+ResultSet class that supports a parent() method, for example. Another
+solution is to somehow automagically modify the objects that exist
+in the current object's result set to have the new position value.

+ $employee->parent( 7 );
+
+=head1 DESCRIPTION
+
+This module provides methods for working with adjacency lists. The
+adjacency list model is a very common way of representing a tree structure.
+In this model each row in a table has a prent ID column that references the
+primary key of another row in the same table. Because of this the primary
+key must only be one column and is usually some sort of integer. The row
+with a parent ID of 0 is the root row and is usually the parent of all
+other rows.
+
+=head1 METHODS
+
+=head2 parent_column
+
+ __PACKAGE__->parent_column('parent_id');
+
+Declares the name of the column that contains the self-referential
+ID which defines the parent row. Defaults to "parent_id".
+
+=cut
+
+__PACKAGE__->mk_classdata( 'parent_column' => 'parent_id' );
+
+=head2 parent
+
+ my $parent = $employee->parent();
+ $employee->parent( $parent_obj );
+ $employee->parent( $parent_id );
+
+Retrieves the object's parent ID, or sets the object's
+parent ID. If setting the parent ID then 0 will be returned
+if the object already has the specified parent, and 1 on
+success.
+
+If you are using the Positioned component this
+module will first move the object to the last position of
+the list, change the parent ID, then move the object to the
+last position of the new list. This ensures the intergrity
+of the positions.
+
+=cut
+
+sub parent {
+ my( $self, $new_parent ) = @_;
+ my $parent_column = $self->parent_column();
+ if ($new_parent) {
+ if (ref($new_parent)) {
+ $new_parent = $new_parent->id() || 0;
+ }
+ return 0 if ($new_parent == ($self->get_column($parent_column)||0));
+ my $positioned = $self->can('position_column');
+ $self->move_last if ($positioned);
+ $self->set_column( $parent_column => $new_parent );
+ if ($positioned) {
+ $self->set_column(
+ $self->position_column() => $self->search( {$self->_parent_clause()} )->count() + 1
+ );
+ }
+ $self->update();
+ return 1;
+ }
+ else {
+ return $self->find( $self->get_column( $parent_column ) );
+ }
+}
+
+=head2 children
+
+ my $children_rs = $employee->children();
+ my @children = $employee->children();
+
+Returns a list or record set, depending on context, of all
+the objects one level below the current one.
+
+If you are using the Positioned component then this method
+will return the children sorted by the position column.
+
+=cut
+
+sub children {
+ my( $self ) = @_;
+ my $rs = $self->search(
+ { $self->parent_column()=>$self->id() },
+ ( $self->can('position_column') ? {order_by=>$self->position_column()} : () )
+ );
+ return $rs->all() if (wantarray());
+ return $rs;
+}
+
+=head2 descendents
+
+Same as children. Declared so that this module is
+compatible with the Tree::NestedSet module.
+
+=cut
+
+#*descendants = \&children;
+
+=head1 PRIVATE METHODS
+
+These methods are used internally. You should never have the
+need to use them.
+
+=head2 _parent_clause
+
+This method is provided as an override of the method in
+DBIC::Positioned. This way Positioned and Tree::AdjacencyList
+may be used together without conflict. Make sure that in
+you component list that you load Tree::AdjacencyList before you
+load Positioned.
+
+This method assumes a parent ID of 0 if none is defined. This
+usually comes in to play if you are just createing the object
+and it has not yet been assigned a parent.
+
+=cut
+
+sub _parent_clause {
+ my( $self ) = @_;
+ return (
+ $self->parent_column() =>
+ $self->get_column($self->parent_column())
