title: 2 Rails Apps, 1 Database (using Heroku)
body: <p>I've made 2 apps, App A and App B. App A's sole purpose is to allow users to sign up and App B's purpose is to take select users from App A email them. Since App A &amp; B were created independently &amp; are hosted in 2 separate Heroku instances, how can App B access the users database in App A? Is there a way to push certain relevant rows from App A to App B?</p>
