Checklist for Heroku/Sinatra/Active Record App Deployment

1. Write your app - YAY!

2. Prepare Your App

• Set up your environments.rb file

  • mkdir config

  • touch config/environments.rb

  • Set it up thusly:

      configure :production, :development do 
      	db = URI.parse(ENV['DATABASE_URL'] || 'postgres://user@localhost/dbname')
      end
      
      ActiveRecord::Base.establish_connection(
      	:adapter => 'postgresql',
      	:host => db.host,
      	:username => db.user,
      	:password => db.password,
      	:database => db.path[1..-1],
      	:encoding => 'utf8'
      )
    

  • Make sure to include environments.rb in your server.rb

      require_relative 'config/environments'
    

• ###Add this "after" to your main sinatra server…

    	after do
    		ActiveRecord::Base.clear_active_connections!
    	end
  

• ###Create your config.ru file…

    	require './server'
    	run Sinatra::Application
  

• ###You need a Gemfile…

  • touch Gemfile

  • Make it say:

      	source "https://rubygems.org"
      	ruby "2.0.0"
      	
      	gem "sinatra", "~> 1.4"
      	gem "sinatra-contrib", "~> 1.4"
      	gem "activerecord", "~> 4.0"
      	gem "pg", "~> 0.17"
    

  • bundle install

  • have you seen your nice Gemfile.lock?

• You need a Procfile!

    	web: bundle exec rackup config.ru -p $PORT
  

##3. Get Ready to Heroku##

• git init

• git commit -m "first commit"

• create app with heroku apps:create thenameofmyapp or heroku create

• run schema migration

  • heroku pg:psql
  • create table in database by running schema

• heroku open and feast your eyes!

Done! Let me know if there is anything missing.
