    @test.nil? should work fine. It’s probably not working because your find method is wrong. Try this instead:

    @test = Model.find_by_id(@someid)
    

    An alternative syntax is:

    @test = Mode.find(@someid)
    

    —Which will raise a RecordNotFound exception if the record doesn’t exist.
