23 DBIx::Class::ResultSourceHandle - Decouple Rows/ResultSets objects from their Source objects
27 This module removes fixed link between Rows/ResultSets and the actual source
28 objects, which gets round the following problems
34 Needing to keep C<$schema> in scope, since any objects/result_sets
35 will have a C<$schema> object through their source handle
39 Large output when using Data::Dump(er) since this class can be set to
40 stringify to almost nothing
44 Closer to being able to do a Serialize::Storable that doesn't require class-based connections
55 my ($class, $data) = @_;
57 $class = ref $class if ref $class;
64 Resolve the moniker into the actual ResultSource object
68 sub resolve { return $_[0]->schema->source($_[0]->source_moniker) }

79 my $to_serialize = { %$self };
81 my $class = $self->schema->class($self->source_moniker);
82 $to_serialize->{schema} = $class;
83 return (Storable::freeze($to_serialize));
88 Thaws frozen handle. Resets the internal schema reference to the package
89 variable C<$thaw_schema>. The recomened way of setting this is to use
90 C<< $schema->thaw($ice) >> which handles this for you.
96 my ($self, $cloning,$ice) = @_;
97 %$self = %{ Storable::thaw($ice) };
99 my $class = delete $self->{schema};
101 $self->{schema} = $thaw_schema;
104 my $rs = $class->result_source_instance;
105 $self->{schema} = $rs->schema if $rs;
108 carp "Unable to restore schema" unless $self->{schema};
