Rails Tips : Prawnto PDF Generator Dynamic File Name

I was getting stuck how to generate dynamic file name for prawn generated pdf file, because there’s lack of example and document here http://cracklabs.com/prawnto/demos

What is Prawnto? Prawnto is is a rails plugin leveraging the new prawn library to produce compiled pdf views, as for me i’m using it for custom reporting tools.

OK, let’s getting back to the problem, what should you do is place prawnto definition in your method rather than in controller’s callbacks :

# /app/controllers/transactions_controller.rb

def show
    prawnto :prawn => { :page_size => 'A4',
                                     :left_margin => 40,
                                     :right_margin => 30,
                                     :top_margin => 40,
                                     :bottom_margin => 30},
                                     :filename => "invoice_#{@transaction.id}_customer_#{@transaction.customer_id}.pdf"
    render :layout => false
end

# /app/views/transactions/show.pdf.prawn

<%= link_to "Generate PDF", transaction_url(transaction.id, :format => 'pdf') %>

Hope this is useful, cheers

Rails Deployment di Phusion Passenger Menggunakan Capistrano

Sesuai dengan request dari Mas Agung Sachli di id-ruby group, saya dengan terpaksa insyaAllah akan membawakan materi Ruby on Rails Deployment untuk Jakarta.rb Edisi Juli, yang akan saya khususkan menggunakan Phusion Passenger yang saat ini sepertinya menjadi lebih populer dibandingkan Mongrel atau Thin.

Berikut merupakan langkah installasi Phusion Passenger (mod_rails) melalui Rubygems, dengan prasyarat Apache Webserver sudah terinstall terlebih dahulu di mesin anda.

• Install passenger gem

sudo gem install passenger

• Install passenger sebagai Apache module

passenger-install-apache2-module

• Tambahkan passenger_module di Apache config agar di-load oleh Apache

LoadModule passenger_module /Library/Ruby/Gems/1.8/gems/passenger-2.2.3/ext/apache2/mod_passenger.so
PassengerRoot /Library/Ruby/Gems/1.8/gems/passenger-2.2.3
PassengerRuby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

Kita akan mendapatkan tiga baris kode diatas setelah installasi passenger gem selesai. Untuk linux memiliki path yang berbeda. Kode di atas merupakan konfigurasi untuk OSX, namun biasanya terletak pada direktori /usr/local
