This week we learned that leaving the create_graph method accessible to the world was a bad idea. So let’s go ahead and delete that route in Sinatra, and instead create a Rake Task for it.
require 'neography/tasks' require './neoflix.rb' namespace :neo4j do task :create do neo = Neography::Rest.new(ENV['NEO4J_URL'] || "http://localhost:7474") create_graph(neo) end end
That’s much better. We can create our graph locally with
or we can run it on Heroku with
heroku run rake neo4j:create
If you create the database locally, you can transfer it to Heroku with the Backup and Restore Options.
Log in to Heroku, the go to your apps https://api.heroku.com/myapps, click on your application (I’ll click on Neoflix) then on the “addons” drop down menu on the right, select Neo4j, and you’ll see this screen come up:
You can zip up the contents of your Neo4j database to neoflix.zip and perform a restore operation.
cd neo4j/data/graph.db zip -r neoflix.zip .
Your Neo4j addon will restart and all your data will be loaded and ready to go.
If you have followed part 1 and part 2 of this series, then you should take what you have learned and create a Neo4j demo application. Take part in the Neo4j Challenge and have a chance at winning awesome prices as well as learning a new technology.
