If there's really no common schema beyond name and e-mail, then you have several options to play with: * Use a serialized hash for the "extra" fields. * Put the "extra" fields in some other table and use associations. * Use a schemaless database such as MongoDB. This is not something that SQL databases do easily. > > Thanks in advance, Pankaj Best, -- Marnen Laibow-Koser http://www.marnen.org [email protected] -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
