DBIx::Class::KiokuDB - Refer to KiokuDB objects from DBIx::Class tables. SYNOPSIS
See DBIx::Class::Schema::KiokuDB. package MyApp::DB::Result::Album; use base qw(DBIx::Class); __PACKAGE__>load_components(qw(Core KiokuDB)); __PACKAGE__->table('album'); __PACKAGE__->add_columns( id => { data_type => "integer" }, title => { data_type => "varchar" }, # the foreign key for the KiokuDB object: metadata => { data_type => "varchar" }, ); __PACKAGE__->set_primary_key('id'); # enable a KiokuDB rel on the column: __PACKAGE__->kiokudb_column('metadata'); DESCRIPTION
This DBIx::Class component provides the code necessary for DBIx::Class::Row objects to refer to KiokuDB objects stored in KiokuDB::Backend::DBI. CLASS METHODS
kiokudb_column $rel Declares a relationship to any KiokuDB object. In future versions adding relationships to different sub-collections will be possible as well. METHODS
store A convenience method that calls "store" in KiokuDB on all referenced KiokuDB objects, and then invokes "insert_or_update" on $self. get_kiokudb_column $col set_kiokudb_column $col, $obj store_kiokudb_column $col, $obj See DBIx::Class::Row. OVERRIDDEN METHODS
new Recognizes objects passed in as column values, much like standard relationships do. insert Also calls "insert" in KiokuDB on all referenced objects that are not in the KiokuDB storage. update Adds a check to ensure that all referenced KiokuDB objects are in storage. perl v5.12.4 2011-10-04 DBIx::Class::KiokuDB(3pm)

KiokuDB::Backend::Role::TXN(3pm)			User Contributed Perl Documentation			  KiokuDB::Backend::Role::TXN(3pm)

KiokuDB::Backend::Role::TXN - Backend level transaction support. SYNOPSIS
package MyBackend; use Moose; with qw( KiokuDB::Backend KiokuDB::Backend::Role::TXN ); sub txn_begin { ... } sub txn_commit { ... } sub txn_rollback { ... } DESCRIPTION
This API is inspired by standard database transactions much like you get with DBI. This is the low level interface required by "txn_do" in KiokuDB. OPTIONAL METHODS
txn_do $code, %callbacks This method should evaluate the code reference in the context of a transaction, inside an "eval". If any errors are caught the transaction should be aborted, otherwise it should be committed. This is much like "txn_do" in DBIx::Class::Schema. The "rollback" callback should be fired when the transaction will be aborted. REQUIRED METHODS
txn_begin [ $parent_txn ] Begin a new transaction. This method can return a transaction handle that will later be passed to "txn_commit" or "txn_rollback" as necessary. The current handle will be passed to nested calls to "txn_begin". txn_commit $txn Commit the transaction. txn_rollback $txn Rollback the transaction. perl v5.12.4 2010-10-11 KiokuDB::Backend::Role::TXN(3pm)
