收到此错误：

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

宝石文件：

gem 'pdfkit'

跑捆绑安装

应用程序.rb：

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

路线.rb：

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

奖项控制器：

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

耙中间件：

use PDFKit::Middleware

耙路线：

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。
