Active Admin查看为PDF [英] Active Admin view to PDF

问题描述

我最近开始在Ruby on Rails中进行开发，因此我认为自己是新手。

I'm starting to develop in Ruby on Rails recently, therefore I consider myself beginner.

我正在测试Active Admin gem（ http://activeadmin.info/ ），将视图导出到PDF时发现了问题。

I'm testing the Active Admin gem ( http://activeadmin.info/ ) and I found a problem when export a view to PDF.

在官方文档中说明了如何自定义下载链接（ http：// activeadmin.info/docs/3-index-pages.html ，位于文档末尾），但对我不起作用。

In the official documentation says how to customize the download links (http://activeadmin.info/docs/3-index-pages.html, it is at the end of the document) but does not work for me.

何时我输入了以下代码行：

When I put the following line of code:

Mymodel ActiveAdmin.register do
  index: download_links => [: pdf]
end

结果是指向localhost：3000 / admin /的链接mymodel.pdf并显示以下错误：无法加载PDF文档。

The result is a link to localhost:3000/admin/mymodel.pdf and the following error displays: "Failed to load PDF document".

两个问题：

1. 您有什么建议？


2. 您能举个例子吗？

我将非常感激。

推荐答案

这是一阵子，但我要添加一个示例对于将来的搜索者来说，ActiveAdmin更具针对性，因为@ user2163649的答案是一种更通用的方法。

This was questioned for a while ago, but I'm adding an example that is a little more specific to ActiveAdmin for the future searchers as @user2163649's answer is a more general approach.

首先，我们需要弄清楚ActiveAdmin不支持PDF导出的盒子。您需要自己实现它。

First we need to make it clear that ActiveAdmin does not support PDF export out of the box. You need to implement it yourself.

我选择了WickedPDF gem来创建PDF，但是您可以从其他一些选择，例如虾，Pdfkit等，根据您的需求和限制。

I picked up WickedPDF gem for PDF creation, but you can choose from several other options such as Prawn, Pdfkit, etc according to your needs and limits.

# Gemfile
gem 'wicked_pdf'

# app/admin/pages.rb
ActiveAdmin.register Page do
  controller do
    # if you want /admin/pages/12345.pdf
    def show
      super do |format|
        format.pdf { render(pdf: "page-#{resource.id}.pdf") }
      end
    end
  end

  # if you want /admin/pages/12345/pdf, pdf_admin_page_path(@page)
  member_action :pdf, method: :get do
    render(pdf: "page-#{resource.id}.pdf")
  end
end

# app/views/admin/order_items/show.pdf.erb
<h1>page <%= resource.id %></h1>
<p><%= resource.body %></p>

# app/views/admin/order_items/show.html.erb
<h1>page <%= resource.id %></h1>
<p><%= resource.body %></p>
