Rails4：PDFKit缺少模板错误(Rails4: Template is missing error with PDFKit)

 我想生成PDF文件，所以我试图使用PDFKit但失败了。 
 
 单击链接时显示以下错误。 
 
ActionView::MissingTemplate (Missing template /show with {:locale=>[:en], :formats=>[:pdf], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in:
  * "/usr/local/rvm/gems/ruby-2.3.0/gems/web-console-2.0.0.beta3/lib/action_dispatch/templates"
  * "/home/ubuntu/workspace/app/views"

 时间表\ show.html.erb 
 
<% provide(:title, @schedule.title) %>
<%= render @schedules %>
 
 schedules \ _schedule.html.erb 
 
...
    <%= link_to "PDF", schedule_path(schedule.id, format: "pdf"), class: "btn btn-sm btn-default" %>
...
 
 schedules_controller.rb 
 
...
respond_to do |format|
  format.html # show.html.erb
  format.pdf do
    html = render_to_string template: "show"

    pdf = PDFKit.new(html, encoding: "UTF-8")

    send_data pdf.to_pdf,
      filename:    "#{@scheudles.id}.pdf",
      type:        "application/pdf",
      disposition: "inline"
  end
end
...
 
 虽然我创建了show.pdf.erb和_schedule.pdf.erb ，其内容与_schedule.pdf.erb相同，但结果是一样的。 

I'd like to generate PDF file, so I am trying to use PDFKit but failing.
 
The following error was displayed when I click the link.
 
ActionView::MissingTemplate (Missing template /show with {:locale=>[:en], :formats=>[:pdf], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in:

  format.html # show.html.erb
  format.pdf do
    html = render_to_string template: "show"

    pdf = PDFKit.new(html, encoding: "UTF-8")

    send_data pdf.to_pdf,
      filename:    "#{@scheudles.id}.pdf",
      type:        "application/pdf",
      disposition: "inline"
  end
end
...
 
Although I create show.pdf.erb and _schedule.pdf.erb which contents is the same as html.erb, the result is the same.
