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"
  * "/usr/local/rvm/gems/ruby-2.3.0/gems/web-console-2.0.0.beta3/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:

  * "/usr/local/rvm/gems/ruby-2.3.0/gems/web-console-2.0.0.beta3/app/views"
 
schedules\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
...
 
Although I create show.pdf.erb and _schedule.pdf.erb which contents is the same as html.erb, the result is the same.

 您应该创建一个由servername和datetime键入的字典  
 示例：from collections import defaultdict  
lines = defaultdict(dict)
with open("file_parse.txt") as f:
    for line in f:
        parts = line.split()
        key = tuple(parts[1:3]) # unique key with servername and datetime
        lines[key][parts[0]] = parts[3]
        lines[key]["servername"] = parts[1]
        lines[key]["datetime"] = parts[3]
res = list(lines.values())
print(res)
# [
#    {'cpudile': 'NaN', 'cpunice': '0.0', 'cpunumber': '40.0', 'cpusystem': '0.0', 'cpuuser': '0.0', 'cpuwait': '0.0', 'datetime': 'NaN', 'servername': '1438084445'},
#    {'cpudile': 'NaN', 'cpunice': '0.0', 'cpunumber': '40.0', 'cpusystem': '0.0', 'cpuuser': '0.0', 'cpuwait': '0.0', 'datetime': 'NaN', 'servername': '1438084440'},
#    {'cpudile': 'NaN', 'cpunice': '0.0', 'cpunumber': '40.0', 'cpusystem': '0.0', 'cpuuser': '0.0', 'cpuwait': '0.0', 'datetime': 'NaN', 'servername': '1438084450'}
# ]

You should create a dictionary that is keyed by servername and datetime 
Example: from collections import defaultdict 
lines = defaultdict(dict)
with open("file_parse.txt") as f:
    for line in f:
        parts = line.split()
        key = tuple(parts[1:3]) # unique key with servername and datetime
        lines[key][parts[0]] = parts[3]
        lines[key]["servername"] = parts[1]
        lines[key]["datetime"] = parts[3]
res = list(lines.values())
print(res)
# [
#    {'cpudile': 'NaN', 'cpunice': '0.0', 'cpunumber': '40.0', 'cpusystem': '0.0', 'cpuuser': '0.0', 'cpuwait': '0.0', 'datetime': 'NaN', 'servername': '1438084445'},
#    {'cpudile': 'NaN', 'cpunice': '0.0', 'cpunumber': '40.0', 'cpusystem': '0.0', 'cpuuser': '0.0', 'cpuwait': '0.0', 'datetime': 'NaN', 'servername': '1438084440'},
#    {'cpudile': 'NaN', 'cpunice': '0.0', 'cpunumber': '40.0', 'cpusystem': '0.0', 'cpuuser': '0.0', 'cpuwait': '0.0', 'datetime': 'NaN', 'servername': '1438084450'}
# ]
