Attaching files to emails using ActionMailer

Hey Guys,

I wish to generate a PDF on the fly to attach to an email. I am using
action mailer and I want to tell the action mailer to attach a PDF
from a URL not a file. All of the examples I have seen attach the
file to the email like so…

  attachment :content_type => "image/jpeg",
    :body =>"an-image.jpg")

Is there anyway I can make it so that “an-image.jpg” is called from a
url on the localhost so something like “localhost/invoice.pdf”. This
will fit in to my rails app as it generates a PDF using prawn and
prawnto from that url.

Thanks for any help

didn’t try this myself, but use open-uri?

  attachment :content_type => "image/jpeg",
    :body => open("").read
