在本地环境中,pdf已成功生成页眉。但在托管linux服务器环境pdf生成没有页眉和页脚。贝洛是我的wkhtmltopdf(WickedPdf)配置

WickedPdf.config = {
    #:wkhtmltopdf => "#{RAILS_ROOT}/pdfbin/wkhtmltopdf-amd64",
    :exe_path => "/home/software/.gems/bin/wkhtmltopdf",
    :layout => "layouts/pdf.html.erb",
    :margin => {    :top=> 40,
                    :bottom => 20,
                    :left=> 30,
                    :right => 30},
    :header => {:html => { :template=> 'layouts/pdf_header.html.erb'}},
    :footer => {:html => { :template=> 'layouts/pdf_footer.html.erb'}}
    #:exe_path => '/usr/bin/wkhtmltopdf'
}

这是我的目录结构我在linux rails托管app \ views \ layouts,在布局中我有pdf.html.erb,pdf_footer.html.erb,pdf_header.html.erb 以上的东西在我的本地Windows开发环境中完美运行,但在生产中pdf生成没有页眉和页脚。所以请帮我生成带页眉和页脚的pdf

应用/视图/布局/ pdf.html.erb

    <link rel="stylesheet" type="text/css" href="<%= "#{RAILS_ROOT}/public/stylesheets/#{@direction}_styles/ui.all.css"%>" media="all" />


  </head>
  <body>

    <%= yield %>

  </body>
</html>

应用/视图/布局/ pdf_header.html.erb

<div id="pdf-header">
      <div class="logo">
        <% if FileTest.exists?("#{RAILS_ROOT}/public/uploads/image/institute_logo.jpg") %>
            <%= image_tag  "#{request.protocol}#{request.host_with_port}/uploads/image/institute_logo.jpg" ,:width => "90",  :height=>"85" %>
          <% else %>

          <div class="fed_logo">
            <%= image_tag  "#{request.protocol}#{request.host_with_port}/images/application/app_fedena_logo.jpg" ,:width => "90",  :height=>"85" %>
    </div>
          <% end %>
      </div>
      <div class="header-content">
        <p><%=Configuration.get_config_value('InstitutionName'); %></p>
        <p><%=Configuration.get_config_value('InstitutionAddress'); %></p>
      </div>

</div>

应用/视图/布局/ pdf_footer.html.erb

<div id="pdf-footer">
  <%= t('signature') %>
</div>

注意* 以上代码在我的Windows开发环境中完美运行(即)使用页眉和页脚正确生成的PDF。 但是当我在Linux生产服务器上托管我的应用程序时,生成的PDF文件没有页眉和页脚。*


已解决的页眉页脚问题,以上是工作代码。上述问题是由于我的文件在生产Linux环境中没有足够的可执行权限。

.erb 放在文件名

的末尾
:header => {:html => { :template=> 'layouts/pdf_header.html.erb'}},
:footer => {:html => { :template=> 'layouts/pdf_footer.html.erb'}}
