Princely

Princely is a simple wrapper for the Prince XML PDF generation library (http://www.princexml.com). It is almost entirely based on the SubImage Prince library found on this blog post:

I have taken the helpers and made them a little bit more generalized and reusable, and created a render option set for pdf generation. The plugin will also automatically register the PDF MimeType so that you can use pdf in controller respond_to blocks.

Example

class Provider::EstimatesController < Provider::BaseController
  def show
    respond_to do |format|
      format.html
      format.pdf do
        render :pdf => "file_name", 
               :template => "controller/action.pdf.erb", 
               :stylesheets => ["application","prince"]
               :layout => "pdf"
      end
    end
  end

  def pdf
    make_and_send_pdf("file_name")
  end
end

Render Defaults

The defaults for the render options are as follows:

layout:      false
template:    the template for the current controller/action
stylesheets: none
