在本地开发环境(windows)中成功生成带有Css样式的pdf。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'

更多信息:

这是我在 linux rails 上托管 app\views\layouts 的目录结构,内部布局我有 pdf.html.erb 、 pdf_footer.html.erb 、 pdf_header.html.erb 以上内容在我的本地完美运行Windows 开发环境,但在生产中生成的 pdf 没有样式。所以请大家帮我生成带有 CSS 样式的 pdf

app/views/layouts/pdf.html.erb

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html dir="<%= (rtl?) ? 'rtl' : 'ltr' %>">
<head>
<% @direction = (rtl?) ? 'rtl/' : '' %>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<%= stylesheet_link_tag([@direction+'application', @direction+'_styles/ui.all'])%>
<%= stylesheet_link_tag(*get_stylesheets) %>
<%= stylesheet_link_tag @direction+"_layouts/pdf" %>
<link rel="stylesheet" type="text/css" href="<%="#{RAILS_ROOT}/public/stylesheets/#{@direction}_layouts/pdf.css" %>" media="all" />
<link rel="stylesheet" type="text/css" href="<%="#{RAILS_ROOT}/public/stylesheets/#{get_stylesheets}.css"%>" media="all" />
<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,这些样式不会被 wkhtmltopdf 获取。所以伙计们请帮助我

最佳答案

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,它运行良好(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

也许这可以帮助您...或其他人...
