Question

尝试使用wicked_pdf gem将HTML转换为PDF时出现以下错误：

pairs = s.scan /"(\d+)"=>"([[:upper:]]+)"/
# [["1430156203913", "ABC"],
#  ["1430156218698", "DEF"],
#  ["1430156219763", "GHI"],
#  ["1430156553620", "JKL"],
#  ["1430156793764", "MNO"],
#  ["1430156799454", "PQR"]]

查看/用户/ index.html.erb：

Hash[pairs].invert.values_at('ABC', 'DEF')
# ["1430156203913", "1430156218698"]

查看/用户/ download_pdf.pdf.erb：

RuntimeError in UsersController#download_pdf

Error: Failed to execute:

Application Trace | Framework Trace | Full Trace
app/controllers/users_controller.rb:7:in `block (2 levels) in download_pdf'
app/controllers/users_controller.rb:6:in `download_pdf'

控制器/ users_controller.rb：

<p>
    <%= link_to "Download pdf",download_pdf_path(:format => 'pdf') %>
</p>

初始化/ wicked_pdf.rb：

<h1>Hello pdf</h1>

的Gemfile：

class UsersController < ApplicationController
    def index

    end
    def download_pdf
    respond_to do |format|
        format.pdf{ render pdf: "download_pdf.pdf.erb"}
    end 
    end
end

请帮我解决此错误并将HTML文件转换为PDF。我正在使用windows-xp

尝试使用Rails 3将HTML转换为PDF时获取RuntimeError
