It can be, but you'll have to do it slightly differently. I'll help you, but you're going to have to explain exactly what you want to have happen.

The point is I want to set the value of the status before it is saved to the database.

No. It's just that your syntax wasn't quite correct.

Many thanks.

Then you want something like

def status=(value)   new_value = do_something_to(value)   self[:status] = new_value # assuming this class is derived from AR end

The reason your attempt to do status = value didn't work is that it was just calling the same method.

Best,
