通过电子邮件作为附件发送回形针文件- Rails

Question

我有一份表格，当潜在的雇员有兴趣为公司工作时，他/她会填写并附上一份简历。意见书将交给公司代表，并附上附件。电子邮件正在通过，但附件不是文件，我不知道如何正确配置它。在提交的电子邮件中，附件中只写着“文档”。

career_mailer.rb

class CareerMailer < ApplicationMailer

  default from: "career@conciergenursingdirect.com"



  def career_inquiry(career)
    @career = career
     attachments['attachment.extension'] = document
    mail(to: "michele@conciergenursingdirect.com", subject: "This is just a test from Jay")
  end
end

career.rb (模型)

class Career < ApplicationRecord

    has_attached_file :document

    validates_attachment_size :document, :less_than => 25.megabytes    
    validates_attachment_presence :document
     validates_attachment_content_type :document, :content_type => ["application/pdf","application/vnd.ms-excel",     
                                                                    "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
                                                                    "application/msword", 
                                                                    "application/vnd.openxmlformats-officedocument.wordprocessingml.document", 
                                                                    "text/plain"]

    email_regex = /\A([\w+\-].?)+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/i

    validates :name, :presence => true,
              :length          => { :maximum => 50 }
    validates :subject, :presence => true,
              :length          => { :maximum => 50 }
    validates :phone, :presence => true,
    :length          => { :maximum => 50 }
    validates :email, :presence => true,
              :format          => {:with => email_regex }
    validates :message, :presence => true,
              :length          => { :maximum => 5000 }

end

careers_controller.rb

class CareersController < ApplicationController
  def new
  @career = Career.new

  end
  def show
    @career = Career.find(params[:id])
  end 

  def create
    # fail
    @career = Career.create(career_params)
    if @career.save
      CareerMailer.career_inquiry(@career).deliver
      redirect_back(fallback_location: root_path)
    else
      flash[:error] = @career.errors.full_messages
      redirect_back(fallback_location: root_path)
    end


  end
  private
  def career_params
    params.require(:career).permit(:name, :phone, :subject, :email, :message, :document)
  end
end

更新

在我的职业邮件中，我正在尝试以下几点：

attachments[career.document.attach_file_name] = File.read(career.document.attach.path)

我得到了以下错误：

更新2

我仍然在做这个工作，但我认为，基于我所读到的一切，我需要在把回形针文件保存到模型之前把它拉出来，所以我会想办法这样做，这样我就可以把上传的简历作为附件发送了。

Answer 1

经过几个小时的尝试和错误，我终于找到了它，这是糟糕的，因为它只有1行。基本上，我所要做的就是在我的career_mailer.rb中添加以下内容：

attachments[@career.document_file_name] = File.read(@career.document.path )

document_file_name实际上是我表中列的名称，其中回形针保存文档的名称。如果您使用回形针作为文件、图像等，这种情况可能会改变。我选择使用文档这个词。

这是对我有用的最后一款产品：

class CareerMailer < ApplicationMailer

  default from: "career@conciergenursingdirect.com"



  def career_inquiry(career)
    @career = career

    attachments['resume'] = File.read( @career.document.path ) 



    mail(to: "michele@conciergenursingdirect.com", subject: "This is just a test from Jay")
  end
end
