ruby-on-rails-3.2 - PDFKit - 未定义方法 'Scan"错误

Question

出现此错误:

NoMethodError in AwardsController#certificate 
undefined method `scan' for #<Array:0x0000000354bd40>

gem 文件:

gem 'pdfkit'

运行捆绑安装

应用.rb:

require 'pdfkit'
config.middleware.use "PDFKit::Middleware"

路线.rb:

match 'awards/certificate/:id' => 'awards#certificate', :as => :certificate, :via => :get

awards_controller:

def certificate
    @award = Award.find(params[:id])
    html = render :layout => false 
    kit = PDFKit.new(html, :page_size => 'Letter')
    kit.stylesheets << RAILS_ROOT + '/public/stylesheets/scaffold.css'
    send_data(kit.to_pdf, :filename => "#{@award.nominee_fullname Certificate}", :type => 'application/pdf')
  end

rake 中间件:

use PDFKit::Middleware

耙路:

certificate GET    /awards/certificate/:id(.:format)     awards#certificate

如果我将 .pdf 放在 URL 的末尾，我会得到:

Routing Error

No route matches [GET] "/highfive/awards/certificate/51"

有人知道我做错了吗？提前致谢。

使用 render_to_string 而不是 render
