My problem is that even though the format is perceived correctly in the mail it only shows text for my attachments. All files are pre-uploaded and just hooked on from the folder they''re contained in the public folder. I send my emails through smtp in my dev / prod) environment file. I Run Rails 3.1 and Ruby 1.9.3. Extraction from an email: ----==_mimepart_4eef18cd87cdb_145c160c9e899096 Date: Mon, 19 Dec 2011 11:58:21 +0100 Mime-Version: 1.0 Content-Type: image/jpeg; charset=UTF-8; filename=7339a0207435.jpg Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename=7339a0207435.jpg From here on only a clutter of chars is rendered in the mail. Any clue to how I can fix this? As far as I know it used to work in Rails 3.0. Code from my mailer class: def send_email(supervisormail, user, params) @supervisormail = supervisormail @user = user acase = @supervisormail.case if Uploadcontent.count(:conditions => ["case_id = #{acase.id}"]) > 0 acase.uploadcontents.each do |uc| if params[uc.id.to_s] attachments[uc.filename] = File.read(''public/uploadedfiles/'' + uc.filename) end end end mail(:to => supervisormail.to, :subject => supervisormail.subject, :from => supervisormail.from, :content_type => "text/plain") end -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
