String primary keys for Sails fixtures

Does Sails have working database fixtures module, that can work with string primary keys? Because Barrels are not :( I try to find any working module but it is tons of trash only.

BTW: Anybody work with Sails in production at all? All question about Sails aren`t answered in Sails github, or gitter or stack. It seems that Sails project are dead and not used in production?

Issues in sails and waterline github are not solved for years...

Bad luck I choose it for real project.
