Composite Primary Keys for ActiveRecords Summary: ActiveRecords/Rails famously doesn't support composite primary keys. For 2 years there has been no support for this aspect of legacy databases. This project will be a fully-featured solution and I welcome use cases and legacy DB schema samples to help make the project work with as many common legacy environments as possible.
