I'm trying to generate emails with rendered PDF attachements using ActionMailer and wicked_pdf. On my site, I'm using already both wicked_pdf and actionmailer separately. I can use wicked_pdf to serve up a pdf in the web app, and can use ActionMailer to send mail, but I'm having trouble attaching rendered pdf content to an ActionMailer (edited for content): class UserMailer < ActionMailer::Base default :from => "webadmin@mydomain.com" def generate_pdf(invoice) render :pdf => "test.pdf", :template => 'invoices/show.pdf.erb', :layout => 'pdf.html' end def email_invoice(invoice) @invoice = invoice attachments["invoice.pdf"] = {:mime_type => 'application/pdf', :encoding => 'Base64', :content => generate_pdf(@invoice)} mail :subject => "Your Invoice", :to => invoice.customer.email end end Using Railscasts 206 (Action Mailer in Rails 3) as a guide, I can send email with my desired rich content, only if I don't try to add my rendered attachment. If I try to add the attachment (as shown above), I get an attachement of what looks to be the right size, only the name of the attachment doesn't come across as expected, nor is it readable as a pdf. In addition to that, the content of my email is missing... Does anyone have any experience using ActionMailer while rendering the PDF on the fly in Rails 3.0? Thanks in advance! --Dan
