I’m sure this has been brought up before but I probably am using the  
wrong keywords to search. I’d like to know if there is a way to use Ruby  
to create dynamic schemas. As an example, I’d like to create an  
administrative page that would allow administers to add or remove fields  
from that page - which results in a modification to the schema of the  
table in the database. Can this be done at runtime without having to  
restart Ruby?

Are you using Rails?

If so, you’re probably going to have better luck on the Rails mailing  
list ([http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails)).

If not, much more information is required.

I’m going to use Rails - Perhaps I will post this question there.
