Rails 3 Render Prawn pdf in ActionMailer

Question

How to render prawn pdf as attachment in ActionMailer? I use delayed_job and don\'t understand, how could I render pdf-file in action mailer (not in controller). What format

Answer 1

My solution:

render_to_string('invoices/show.pdf', :type => :prawn)

PDF was corrupted because I didn't write block for mail function and multi-part email was incorrect.
