Facebook/Force.com/Heroku sample app -- Ruby
This is a sample Facebook app showing use of the Force.com REST API, written in Ruby, designed for deployment to Heroku.
This app was shown at my Cloudstock 2012 session 'Create a Force.com-Powered Facebook App on Heroku'. Presentation slides.
Run locally
Install dependencies:
bundle install
Create an app on Facebook and set the Website URL to http://localhost:5000/.
Copy the App ID and Secret from the Facebook app settings page into your .env:
echo FACEBOOK_APP_ID=12345 >> .env
echo FACEBOOK_SECRET=abcde >> .env
Create a remote access app in your org on Force.com and set the Website URL to http://localhost:5000/.
Copy the Consumer Key and Secret, and the username and password of an API user, from the Force.com remote app settings page into your .env:
echo SFDC_OAUTH_CLIENT_ID=67890 >> .env
echo SFDC_OAUTH_CLIENT_SECRET=fghij >> .env
echo USERNAME=apiuser@example.com >> .env
echo PASSWORD=******** >> .env
Launch the app with Foreman:
foreman start
Deploy to Heroku
If you prefer to deploy yourself, push this code to a new Heroku app on the Cedar stack, then copy the IDs, secrets and credentials into your config vars:
heroku create --stack cedar
git push heroku master
heroku config:add FACEBOOK_APP_ID=12345 FACEBOOK_SECRET=abcde \
SFDC_OAUTH_CLIENT_ID=67890 SFDC_OAUTH_CLIENT_SECRET=fghij USERNAME=apiuser@example.com \
PASSWORD=********
Enter the URL for your Heroku app into the Website URL section of the Facebook app settings page, then you can visit your app on the web.
