Hello,  
I want to update a record in the table.here r the details.

I have to modify a malinglist that contains email addresses to add  
another email in the list. But when i do  
@mailinglist.update\_attributes(params[:mailinglist])  
my old email addresses in the list are deleted and only new one remains

how can i modify the list so that i can add instead of replacing the old  
email addresses.  
Thank you.

Maybe you can try:  
@mailinglist.new(params[:mailinglist])  
@mailinglist.save
