- Create a DBIx::Class::FilterColumn to replace inflate/deflate. This
We should still support the old inflate/deflate syntax, but this new
way should be recommended.

- Extract DBIC::SQL::Abstract into a separate module for CPAN
- Chop PK::Auto::Foo up to have PK::Auto refer to an appropriate
DBIx::Storage::DBI::Foo, which will be loaded on connect from Driver info?
+(done -> 0.06001!)

+ Add the ability for deploy to be given a directory and grab <dbname>.sql

+=head1 DESCRIPTION
+
+This module provides a simple interface for modifying the ordered
+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 grouping_column
+
+ __PACKAGE__->grouping_column('group_id');
+
+This method specified a column to limit all queries in
+this module by. This effectively allows you to have multiple
+ordered lists within the same table.
+
+=cut
+
+__PACKAGE__->mk_classdata( 'grouping_column' );
+
+=head2 siblings
+
+ my $rs = $item->siblings();

+ );
+ return $rs->all() if (wantarray());
+ return $rs;
+}
+
+=head2 first_sibling
+
+ my $sibling = $item->first_sibling();

+=head2 move_previous

+ $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 {

+ if (!$self->get_column($position_column));
+ return $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;
+ return $self->next::method( @_ );
+}
+
+=head1 PRIVATE METHODS
+
+These methods are used internally. You should never have the
+need to use them.
+
+=head2 _grouping_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 _grouping_clause {
+ my( $self ) = @_;
+ my $col = $self->grouping_column();
+ if ($col) {
+ return ( $col => $self->get_column($col) );
+ }
+ 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.
