Answer 1

Finally its done with prawn and prawn-rails. Here are the details.

To make my system ready

# Add this to your Gemfile
gem 'prawn'
gem 'prawn_rails'

# run
bundle install

I hit the url http://localhost:3000/regions i.e. to hit the index of RegionsController and it shows the page as pdf format.

I have a Region Model with a single attribute name. Has two entries in regions table.

[
 #,
 #
]

My Controller Method:

def index
    @regions = Region.all # Should return two region objects :)

    respond_to do |format|
        format.html # index.html.erb
        format.json { render json: @regions }
        format.pdf    # <---------- This will handle the pdf response
    end
end

I have created a view file in views/regions/index.pdf.prawn. Anyway the view file name format is :action.pdf.prawn and the view file is containing

prawn_document() do |pdf|
    @regions.each {|r| pdf.text r.name}
end

This will just output the name of Regions.

Thats it. You have your page in pdf format. Now just play with all other options provided by Prawn and Prawn-Rails. You can find some here - http://prawn-rails-demo.heroku.com/

Just thinking to write a series of blogs guiding how to use different pdf generation tool with rails 3.

Let me know if it solves your problem.
