sending email with attachments

Hi

Could anyone please give an example of sending mails with attachments in rails using actionmailer?    I have a user in users table whose attachments is stored in attachments table it self( Relation is user has_many attachments ; attachment belongs_to user). Sender for example is admin@example.com. suppose user1 has two attachments "test1.pdf" and "test2.doc"

Thanks Tom

Hi    A detailed requirement of the above is as

  I have a message model, message_participant model, and attachments model. The relations are

message has_many message_participants message has_many attachments

   attachment using paperclip I am storing in database it self. I have in hand a message object which has subject, body etc. So clearly this message has a sender and many recipients. This I can find out. My requirement is to send each of the message recipients this message with its attachments

   I have all the data in my hand . What I need is, to send same email with attachments to the recipients

    Please help Thanks Tom
