Lex to LIVES

A Ruby script that takes Lexington Health Department restaurant inspection scores to the LIVES standard.

Assembled by OpenLexington for Code Across America 2013

It is deployed on Heroku (app name: lives-etl), which runs a scheduled job each day to look for new health dept scores.

The health scores data generated by this script is stored in a separate GitHub repo

To convert health department food scores manually

mv .env-sample .env Add your GitHub creds (or use a dummy GitHub account for automation)

  • extracts scores from health department site
  • transforms them to lives format
  • loads to github repo

bundle exec ruby lives_etl.rb

Deploy to Heroku for automation

Install buildpack to enable rugged gem

$ heroku create my-etl-app
$ heroku buildpacks:set https://github.com/ddollar/heroku-buildpack-multi.git
$ heroku config:set GITHUB_USER=foo
$ heroku config:set GITHUB_PASS=bar
$ git push heroku master
$ heroku run bundle exec irb

irb(main):001:0> require 'rugged'
=> true

Warning: The buildpack succeeds on initial deploy and then fails on later deploys. This fixes the issue:

heroku plugins:install https://github.com/heroku/heroku-repo.git
heroku repo:purge_cache -a my-etl-app

Enable automated ETL

Add Heroku Scheduler add-on to Heroku instance

set to run daily:

bundle exec ruby lives_etl.rb <permalinik to health scores>

eg bundle exec ruby lives_etl.rb "http://lexingtonhealthdepartment.org/Portals/0/environmental%20health/most_recent_food_scores.xls"

To check when scores have changed on the Health Dept page

Use http://www.changedetection.com/monitor.html

That way you get a notification that the scores have changed and the automation should have kicked off.
