I have the following code: members.select {|m| m.role.assignable?}.collect {|m| m.role}.sort
There are two tables: "roles" and "members". One role record may have many foreign member records. But in this case I get many same roles, I want to apply "distinct" operation to make roles unique in results. How can I do this? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
