Hi I have an ActiveRecord class ServiceDesk and a string "ServiceDesk" .How can I convert the string "ServiceDesk" to create a new object of the class ServiceDesk? Concept is made clear below. model = "ServiceDesk" // Now the variable, model, contains the string "ServiceDesk" which is the name of an active record class. I am trying to achieve the following. how can I really achieve this.. Thanks in advance. model.find(29) Sijo -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If not you can use model = "ServiceDesk".constantize Fred> > I am trying to achieve the following. how can I really achieve this.. > Thanks in advance. > > > model.find(29) > > Sijo > -- > Posted via http://www.ruby-forum.com/. > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Because in model="ServiceDesk" "ServiceDesk" is one of the fiels of a table of type String.And there is also other entries in that field like Incident,etc.All are names of ActiveRecord modelclasses Sijo -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
