Using Wicked_PDF with Rails 3.1

wicked_pdf.rb

#in config/initializers/wicked_pdf.rb
module WickedPdfHelper
  def wicked_pdf_stylesheet_link_tag(*sources)
    sources.collect { |source|
      "<style type='text/css'>#{Rails.application.assets.find_asset("#{source}.css").body}</style>"
    }.join("\n").gsub(/url\(['"](.+)['"]\)(.+)/,%[url("#{wicked_pdf_image_location("\\1")}")\\2]).html_safe
  end

  def wicked_pdf_image_tag(img, options={})
    image_tag wicked_pdf_image_location(img), options
  end
  
  def wicked_pdf_image_location(img)
    "file://#{Rails.root.join('app', 'assets', 'images', img)}"
  end
  
  def wicked_pdf_javascript_src_tag(jsfile)
    "<script type='text/javascript'>#{Rails.application.assets.find_asset("#{source}.js").body}</script>"
  end

  def wicked_pdf_javascript_include_tag(*sources)
    sources.collect{ |source| wicked_pdf_javascript_src_tag(source, {}) }.join("\n").html_safe
  end
end
