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)

And hence Kernel.const_get(model).new.

Since you're working with Rails and therefore ActiveSupport, you can do:

"ServiceDesk".constantize.new
