Composite Primary Keys for ActiveRecords Bug fix release - 0.3.3 Notes: Fixed errors with id= and create. Note, the create method does not use sequences to generate ids for you. If anyone has any use cases where their DBs generate ids for their composite keys, pls let me know - we may need to add some syntax to the set\_primary\_keys command. Url: [http://compositekeys.rubyforge.org](http://compositekeys.rubyforge.org) 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. Cheers Nic
