In my Rails app I have delayed_job gem to delay all the emails, the problem with this appear when I want to have some attachments in the emails, in development I store then in tmp folder. I Heroku I thought that might be possible as well but I get the error the there is no file in that folder. This is my code inside my controller: def send_bill @sale = Sale.find(params[:id]) @client = @sale.client create_pdf(@sale, @client) PdfMailer.delay.send_pdf_info(@client, current_user.email) @bill.update(sent: true) flash.now.notice = "Bill was sent successfully" render :show end The method create_pdf is the one that create the pdf and store it in the tmp folder. def create_pdf(sale, client, is_bill = true) name = is_bill ? "factura.pdf" : "presupuesto.pdf" action = is_bill ? "bills/show" : "bills/budget" @sale = sale @client = client @bill = @sale.bills.first if is_bill file = File.new("#{Rails.root}/tmp/#{name}", "w+") kit = PDFKit.new( render_to_string(action: "#{action}", layout: 'pdf', format: "pdf"), :page_size => 'A4') file = kit.to_file(file.path) end Inside my mailer the code is: def send_pdf_info(client, current_user_email) @client = client attachments["Factura.pdf"] = File.read(#{Rails.root}/tmp/factura.pdf") mail(to: default_to(@client.email), bcc: current_user_email, subject: "Factura Printoria") end I'm not able to solve this. Any help will be really appreciated. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
