Since a recent refactoring[1] is merged, few compute methods are being called at record creation, and throws traceback because of newID. This commit fixes the traceback by improving the compute methods and thus enable users to create records of slide contents and forums. Note - compute fields should be assigned a value, and so we update the recordset with default values while creation. See below PR for more information.
