DBIx::Class::Row - Basic row methods
L<DBIx::Class::ResultSet> object.
When calling it directly, you will not get a complete, usable row
-object until you pass or set the C<source_handle> attribute, to a
+object until you pass or set the C<result_source> attribute, to a
L<DBIx::Class::ResultSource> instance that is attached to a
L<DBIx::Class::Schema> with a valid connection.
C<$attrs> is a hashref of column name, value data. It can also contain
-some other attributes such as the C<source_handle>.
+some other attributes such as the C<result_source>.
Passing an object, or an arrayref of objects as a value will call
L<DBIx::Class::Relationship::Base/set_from_related> for you. When
