How to implement multiple attachments to messages?

[ditanand]

I am using the Mailboxer gem.

What is the best way to set up my controller so it saves all the attachments? (loop through it?)

Would making a new model called "message_attachment" be a good idea? In that case, how do I set up the message model (which I currently don't have in my model folder) so I can include "has_many :message_attachments"? please provide me a solution or a sample code
thanks.
