+This document describes DBIx::Class::ResultSet::RecursiveUpdate version 0.004
=head1 SYNOPSIS
+The functional interface:
+
+ my $new_item = DBIx::Class::ResultSet::RecursiveUpdate::Functions::recursive_update({
+ id => 1,
+ owned_dvds => [
+ {
+ title => 'One Flew Over the Cuckoo's Nest'
+ }
+ ]
+ }
+ );
+
+
+As ResultSet subclass:
+
__PACKAGE__->load_namespaces( default_resultset_class => '+DBIx::Class::ResultSet::RecursiveUpdate' );
in the Schema file (see t/lib/DBSchema.pm). Or appriopriate 'use base' in the ResultSet classes.
=head1 DESCRIPTION
+This is still experimental. I've added a functional interface so that it can be used
+in Form Processors and not require modification of the model.
You can feed the ->create method with a recursive datastructure and have the related records
created. Unfortunately you cannot do a similar thing with update_or_create - this module
[ 'id' ]
);
+This will work with a new DBIC release.
For a many_to_many (pseudo) relation you can supply a list of primary keys
from the other table - and it will link the record at hand to those and
only those records identified by them. This is convenient for handling web
forms with check boxes (or a SELECT box with multiple choice) that let you
-update such (pseudo) relations.
+update such (pseudo) relations.
For a description how to set up base classes for ResultSets see load_namespaces
in DBIx::Class::Schema.
