在本地开发环境(windows) pdf 中成功生成了 Css 样式。但是在托管 linux 服务器环境中生成的 pdf 没有应用 css 样式。下面是我的 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 上,在布局内我有 pdf.html.erb 、 pdf_footer.html.erb 、 pdf_header.html.erb 上面的东西在我的本地 Windows 开发环境中完美运行,但在生产中生成的 pdf 没有样式。所以请大家帮我制作带有 CSS 样式的 pdf

应用程序/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>

pdf.html.erb 包含用于呈现 pdf 的所有样式信息,在托管环境中,这些样式不是由 wkhtmltopdf 获取的。所以请大家帮帮我

当我在 Heroku 上部署我的应用程序时,我遇到了与 PDFKit 类似的问题。现在,它工作正常(我已将二进制文件包含到项目中)。

在我的布局中:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <title>Page title</title>
  <meta http-equiv="X-UA-Compatible" content="IE=8" />
    <%= csrf_meta_tags %>
  <style type="text/css" media="all">
    <%= Rails.application.assets['my_css'].to_s.gsub(/\/assets/,"#{root_url}assets") %>
  </style>
</head>
<body>
  <%= yield %>
</body>
</html>

在初始化器中:

# config/initializers/pdfkit.rb
PDFKit.configure do |config|
  if Rails.env.staging? || Rails.env.production?
    config.wkhtmltopdf = Rails.root.join('bin', 'wkhtmltopdf-amd64').to_s
  else
    config.wkhtmltopdf = '/Users/my_user_name/.rvm/gems/ruby-1.9.2-p0@my_project/bin/wkhtmltopdf'
  end
  config.default_options = {
    :page_size => 'A4',
    :margin_top => '0in',
    :margin_right => '0in',
    :margin_bottom => '0in',
    :margin_left => '0in',
    :orientation => 'Portrait'
  }
  # Use only if your external hostname is unavailable on the server.
  config.root_url = "http://localhost:3000" unless Rails.env.staging? || Rails.env.production?
end

也许这可以帮助你......或其他人......
