[英]Ruby on rails wkhtmltopdf css style sheets not rendering on production (linux) server
在本地开发环境(windows)中,已成功生成Css样式的pdf。 但是在托管linux服务器环境时生成的pdf没有应用css styles.Below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'
}

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。 所以伙计们请帮助我
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在项目中)。
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......
