Send paperclip file via email as an attachment - Rails

Question

I have a form that when a potential hire is interested in working for the company he/she fills it out and attaches a resume. The submission will go to a company representative with the attachment. The email is going through but the attachment is not the document and I cannot figure out how to configure it properly. In the submission email the attachment just says "document".

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 (model)

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

UPDATE

I am trying the following in my career mailer:

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

I am getting the following error:

UPDATE 2

I am still working on this but I think based on everything I've read I need to pull the paperclip file before it saves to the model so I am going to figure out how to do so so I can send the uploaded resume as an attachment.

Answer 1

After hours of trial and error I finally figured it out and it sucks cause it was only 1 line. Basically all I had to do was add the following to my career_mailer.rb:

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

The document_file_name is actually the name of the column in my table where paperclip saves the name of the document. This could change if you used paperclip for file, image, et cetera. I chose to use the word document.

This is the final product that worked for me:

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
