우편 번호의 새우 파일에서 PDF 파일 다운로드

Question

웹 애플리케이션에서 나는 새우와 함께 청구서를 생성합니다.

나는 지폐로 된 파일로 모든 청구서를 다운로드하고 싶습니다!

def download 
    bills = Bill.search(params[:q]).result(distinct: true).paginate(:page => params[:page], limit: 20, order: "paid_at DESC") 

    bills.each do |b| 
    Prawn::Document.generate("#{Rails.root}/public/pdfs/web_#{b.reference}.pdf") 
    end 


    require 'rubygems' 
    require 'zip' 
    zipfile_name = "#{Rails.root}/public/pdfs/factures.zip" 
    Zip::File.open(zipfile_name, Zip::File::CREATE) do |zipfile| 
    bills.each do |bill| 
     zipfile.add("web_#{bill.reference}.pdf", "#{Rails.root}/public/pdfs/web_#{bill.reference}.pdf") 
    end 
    end 

    path = File.join(Rails.root, "public", "pdfs") 
    send_file File.join(path, "factures.zip") 
end 

는하지만 PDF 파일 내가 PDF를 생성 할 수 있습니다은 "* .prawn"파일을 지정하지 않기 때문에 비어 :

내가 그랬어!

아무에게도 그렇게 할 수 있습니까?

감사

내 컨트롤러에서 fonction입니다 :

def download 
    bills = Bill.search(params[:q]).result(distinct: true).paginate(:page => params[:page], limit: 20, order: "paid_at DESC") 

    require 'rubygems' 
    require 'zip' 
    require 'bill' 
    zipfile_name = "#{Rails.root}/tmp/pdfs/factures.zip" 
    Zip::File.open(zipfile_name, Zip::File::CREATE) do |zipfile| 
     bills.each do |bill| 
     temp_pdf = Tempfile.new("web_#{bill.reference}.pdf") 
     temp_pdf.binmode 
     temp_prawn_pdf = BillPdf.new(bill)

내 의견 더에 확장하려면, 아래의 코드 리팩토링을 참조하십시오. 보안상의 이유로 위험한 공개 디렉토리에 파일을 추가하는 대신 Tempfile을 사용할 수 있습니다. 이 부분을 약간 조정해야 할 수도 있지만 Tempfile 뒤에 기본 아이디어를 제공해야합니다.

def download 
    bills = Bill.search(params[:q]).result(distinct: true).paginate(:page => params[:page], limit: 20, order: "paid_at DESC") 

    require 'rubygems' 
    require 'zip' 
    zipfile_name = Tempfile.new(["#{Rails.root}/tmp/factures", '.zip']) 
    Zip::File.open(zipfile_name, Zip::File::CREATE) do |zipfile| 
    bills.each do |bill| 
     temp_pdf = Tempfile.new(["basic_questions_#{Time.now.to_i}", '.pdf']) 
     temp_pdf.binmode 
     temp_prawn_pdf = Prawn::Document.new(#WHATEVER YOUR PARAMETERS ARE) 
     temp_pdf.write temp_prawn_pdf.render 
     temp_pdf.rewind 
     zipfile.add("web_#{bill.reference}.pdf", "#{temp_pdf.path}") 
     temp_pdf.close 
    end 
    end 

    path = File.join(Rails.root, "public", "pdfs") 
    send_file File.join(path, "factures.zip") 
ensure 
    zipfile_name.close 
end
