• Rails 3.0x
• Ruby > 1.8.7

Install

1.Add to the Rails Gemfile

gem 'prawn-rails'

to the Rails Gemfile
prawn and prawn-table is a dependency so no need to mention it in the projects Gemfile
but can mention a specific version if your Gemfile, if you want

Usage

Create a view with pdf as format and prawn as handler
so filename should look like example.pdf.prawn

we provide a helper called prawn_document
it builds a PrawnRails::Document with default options. Can override with page_size and page_layout
example contents of example.pdf.prawn

prawn_document(:page_layout => :landscape) do |pdf|
  pdf.text "Hello World"
end

No need to call pdf.render, it is called by prawn_document

Your available to use all prawn document methods like pdf.text pdf.font_size and also
block like pdf.font(FONT_NAME,opts) do pdf.XXXX end

For more documentation go to the manual

Build in helpers

• html_strip(html)
  Removes the html tags from a string

Default configuration

Add a prawn-rails.rb config to your Rails app under config/initializers like this

PrawnRails.config do |config|
  config.page_layout = :portrait
  config.page_size   = "A4"
  config.skip_page_creation = false
end

by default page_layout is portrait and page_size is “A4”
also skip_page_creation is set to false by default, if it is set to true
then have to create the first page yourself for eg.

pdf.start_new_page size: "A4", page_layout: :landscape

Examples

1. Hello World

   hello.pdf.prawn

    pdf.text hello world
   

2. ** Using Active Record **

   myproducts.pdf.prawn

    pdf.text "Current Products are"
    pdf.move_down 20
    pdf.table(@products.collect{ |p| [p.name,p.price]})

Dev Notes

Gem works with any rails 3.0 version and ruby but for development It should be atlest Rails 3.1 (for the testing env)
I’ll try to fix that
