Rails:如何将模型的详细信息打印到A4 PDF页面? [英] Rails: How to print model's details to A4 PDF page?

问题描述

在我的工作管理应用程序中，我想准备一张A4页的收据给客户.

In my Job Management application I would like to prepare an A4 page receipt to customer.

因此，我需要以某种方式将Job模型的详细信息打印到一个A4 PDF页面上.

Thus, I need to print somehow Job model's details to a single A4 PDF page.

Rails中是否有用于此目的的任何内置工具?

Are the any built-in tools in Rails for this purpose ?

如果没有，最好的方法是什么?

If no, what would be the best way to go ?

推荐答案

基本上有两个选项:(任何PDF创建都需要gem-Rails没有默认的PDF创建).

1. 使用 Prawn 创建纯PDF，您必须使用Prawn API进行所有格式设置

1. Create a pure PDF using Prawn, You have to do all the formatting using the Prawn API

创建收据的HTML版本并将其转换为PDF，做到这一点的更好的方法之一是 PDFkit .使用基于Web套件的浏览器引擎.

Create a HTML version of your receipt and convert it to PDF, One of the better gems to do this is PDFkit. which uses a web-kit powered browser engine.

它们都很好用，对于一页文档，我通常使用PDFkit转换HTML，对于要处理很多页面的较大文档，我使用Prawn，因为它可以为您提供较小的文件大小并更好地处理多个页面.

They both work good, For one page documents I usually use PDFkit to convert HTML and for larger documents that are going have lots of pages I use Prawn because it gives you a smaller file size and handles multiple pages better.

我的建议是制作HTML收据并将其显示在屏幕上，并为用户提供使用 PDFkit .

My suggestion would be to make a HTML receipt and display it on the screen and give the user an option to save a PDF version using PDFkit.

Windows安装. (未经测试-Windows和我已经分开了.)

windows install. (not tested - windows and I have parted company.)

下载wkhtmltopdf的Windows安装程序: win-wkhtmltopdf

Download the windows installer for wkhtmltopdf: win-wkhtmltopdf

现在创建一个初始化文件，例如config/intializers/pdfkit_config.rb

now create an initializer file, e.g. config/intializers/pdfkit_config.rb

设置本地计算机上wkhtmltopdf的绝对路径:

in pdfkit_config.rb set the absolute path to wkhtmltopdf on your local machine:

PDFKit.configure do |config|
  if RAILS_ENV == 'development'
    config.wkhtmltopdf = 'D:\path\to\your\wkhtmltopdf' #this bit i'm not sure about
  else
    config.wkhtmltopdf = "#{RAILS_ROOT}/lib/wkhtmltopdf"
  end
end

对于您的生产E​​NV，实际上您可以在回购单中拥有wkhtmltopdf的副本，当然是unix版本. (在git添加之前，请记住chmod + x它)

for your production ENV you can actually just have a copy of wkhtmltopdf in you repo, a unix version of course. (remember to chmod +x it before you git add it)
