Felix, Wow! Thank you very much for the detail and clear answer. I knew there was something wrong when I had to "throw" and "catch." I read that such construct is rare. Following your advices, I have rewritten the whole thing into validate and before_save, and elevates the "save" operation out of the model. The conditional statement that I previously had buried in another model which was used to "throw" now is in the validation.
I did not expect that the original question would lead me to improve a good portion of the code following the Rails good practices. Thanks again. I still have this nagging question though: How do I prevent an attribute from being written to from outside the class? In other words, how do I make a setter function private so that only other functions in the class can call it. Thanks everyone. You all have been so helpful. I am very appreciative of this community.
