Trigger python script on raspberry pi from a rails application
There are many "easy" ways, depending on your skills.
Maybe: "Write triggers, which are sending the notify on insert/update" is the hint you need?
I have a rails application, and when there is an update to one of the rows in my database, I want to run a python script which is on a raspberry pi (example: lights up a LED when a user is created). I'm using PostgreSQL and have looked into NOTIFY/LISTEN channels, but can't quite figure that out. Is there an easy way to do this? The raspberry pi will not be on the same network as the rails application.
