Rails Prawn converting my index table into a pdf

I am trying to create a .pdf that lists all of my projects(#index).

I found a great link-How do generate PDFs in Rails with Prawn, however it was from 2008 and wanted me to use the prawnto plugin.

I am using Rails 3.2.13 so I decided to use the gem prawn and RailsCast #153 PDFs with Prawn (revised), for reference. I was able to successfully get Prawn working in my:

    projects_controller

    def show

I am having trouble getting the .pdfs working in my def index though.

I tried to just mimic what I did, using the tutoiral for def show, for def index but am getting a routing error.

Here is my code thus far:

Gemfile

gem 'prawn', '0.12.0'

projects_controller.rb

class ProjectsController < ApplicationController

    def index 

    redirect_to action: :active, search =>params[:search]

    end

    def active

    @action = "active"
    ....
    ....  // search code
    ....  // kaminari code
    @projects = Project.order(sort_column + "" + sort_direction)

    respond_to do |format|
    format.json { render "index" }
    format.html { render "index" }
    format.pdf do
       pdf = ProjectAllPdf.new(@projects)
       send_data pdf.render, filename: "project_#{@project.product}.pdf",
                             type: "application/pdf",
                             disposition: "inline"
         end
       end
     end

     def show
       @project = Project.find(params[:id])

       respond_to do |format|
       format.json { render json:@project }
       format.html # show.html.erb
       format.pdf do
         pdf = ProjectPdf.new(@project)
         send_data pdf.render, filename: "project_#{@project.product}.pdf",
                             type: "application/pdf",
                             disposition: "inline"
       end
      end
     end
end

show.html.erb

<p><%= link_to "Printable Receipt (PDF)", project_path(@project, format: "pdf") %></p>

index.html.erb

<p><%= link_to "Printable Receipt (PDF)", projects_path(@projects, format: "pdf") %></p>

I then formatted my file project_pdf.rb

class ProjectPdf < Prawn::Document
  def initialize(project)
    super(top_margin: 70)
    @project = project
    overview_print
  end

  def overview_print
    text "Project #{@project.product}", size: 24, style: :bold, align: :center
    move_down 30
    text "<b>Product:</b>  #{@project.product}", :inline_format => true
    move_down 8
    text "<b>Version Number:</b>  #{@project.version_number}", :inline_format => true
    move_down 8
    ....
    ....
  end
end

I then tried to mimic the last file to get #index working

projectall_pdf.rb

class ProjectAllPdf < Prawn::Document
  def initialize(project)
    super(top_margin: 70)
    @project = project
    overview_print
  end

  def overview_print
    @projects.each do |project|
    text "<b>Product:</b>  #{@project.product}", :inline_format => true
    move_down 8
    text "<b>Version Number:</b>  #{@project.version_number}", :inline_format => true
    move_down 8
    ....
    ....
    end
    end
  end

Everything works great for #show. I just obviously have gotten myself mixed up on how to do the #index portions (def active, linking the .pdf in index.html.erb and projectall_pdf.rb)

I thought I would post an answer to my question, hopefully it helps somebody.

I actually went ahead and used the 'gem prawnto_2', :require => "prawnto"

It allowed me to use the prawnto and the prawnto tutorial with Rails 3.2

I then just created (method).pdf.prawn pages in my app/views/projects folder.

Then just add your custom pdf code to have you want to layout your pdf views.
