Question

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 se

Answer 1

I used of Unixmonkey's solutions above, but then when I upgraded to rails 3.1.rc4 setting the @lookup_context instance variable no longer worked. Perhaps there's another way to achieve the same clearing of the lookup context, but for now, setting the attachment in the mail block works fine like so:

  def results_email(participant, program)
    mail(:to => participant.email,
         :subject => "my subject") do |format|
      format.text
      format.html
      format.pdf do
        attachments['trust_quotient_results.pdf'] = WickedPdf.new.pdf_from_string(
          render_to_string :pdf => "results",
               :template => '/test_sessions/results.pdf.erb',
               :layout => 'pdf.html')
      end
   end
  end
