如何将联系表单中上传的pdf文件作为邮件附件发送

请原谅我的noob问题。

我想将联系表单中上传的pdf文件作为邮件的附件发送。

class ContactPagesController < ApplicationController def new @contact_page = ContactPage.new end def create @contact_page = ContactPage.new(contact_page_params) if @contact_page.save contact_page = @contact_page ContactMailer.contact_email(contact_page).deliver_now flash[:notice]="we have recieved your details successfully" redirect_to root_path else if @contact_page.errors.any? flash[:notice]= "Please fill all the manditory fields" end render :new end end private def contact_page_params params.require(:contact_page).permit( :name, :email, :phone, :messsage, :document) end end 

我的邮件

  class ContactMailer < ApplicationMailer default to: '[e-mail]' def contact_email(contact_page) @contact_page = contact_page mail(from: '[e-mail]', subject: 'Recieved A Contact Enquery') end end 

contact_email.html.erb

电子邮件已成功触发。如何将文档作为电子邮件的附件发送？

任何帮助都得到了高度的赞赏。谢谢！

试试这个：

 def contact_email(pdf,email,contact_page) @contact_page = contact_page mail(to: email, subject: "Recieved A Contact Enquery") mail.attachments['test.pdf'] = { mime_type: 'application/pdf; charset=UTF-8 ;', content: pdf } OR mail.attachments['test.pdf'] = File.read('path/to/file.pdf') end
