Integrating Toto and a Sinatra app in 10 steps

Integrating a Sinatra and toto application is a little tricky for those unfamiliar with hosting multiple Rack applications in a single Rack instance. To integrate these two for AutoMapper.org, I followed similar instructions from the toto wiki:

1. cd your_sinatra_app
2. mkdir blog
3. cd blog
4. git clone git://github.com/cloudhead/dorothy.git .
5. merge the contents of the dorothy .gems file with the .gems file in the root of your Sinatra application
6. remove the files needed for a standalone toto install
   1. rm README
   2. rm Rakefile (you may want to move the toto rakefile to the root directory to take advantage of the “new” task for creating new posts.)
   3. rm config.ru
   4. rm .gems
   5. rm -rf public
   6. rm -rf .git
7. cd .. (back to the root of your Sinatra app)
8. create a Rack config file, config.ru, in your Sinatra root, if it doesn’t already exist
9. Open config.ru in your favorite text editor and add the following:

   require 'toto'
   require './app'
   
   use Rack::ShowExceptions
   
   use Rack::CommonLogger
   
   #run the toto application
   
   toto = Toto::Server.new do
   
     #override the default location for the toto directories
     Toto::Paths = {
       :templates => "blog/templates",
       :pages => "blog/templates/pages",
       :articles => "blog/articles"
     }
   
     #set your config variables here
     set :title, "Your Blog Title"
     set :date, lambda {|now| now.strftime("%B #{now.day.ordinal} %Y") }
     set :summary,   :max => 500
     set :root, "blog"
     set :url, "http://your-blog.heroku.com/blog/"
   
   end
   
   #create a rack app
   
   app = Rack::Builder.new do
   
     use Rack::CommonLogger
   
     #map requests to /blog to toto
     map '/blog' do
     	run toto
     end
   
     #map all the other requests to sinatra
     map '/' do
       run SinatraApp
     end
   end.to_app
   
   run app

10. Open your Sinatra app and wrap any Sinatra code with a class “SinatraApp” that inherits from Sinatra::Base:

    require 'rubygems'
    require 'sinatra'
    
    class SinatraApp < Sinatra::Base
      get '/' do
        "I love lamp"
      end
    end

Now test your code with thin or any other rack-enabled test web server and push! A full working application can be found at my github.
