Question

Normally, when I deploy to Heroku, I create the heroku app from within the Rails console with the command

heroku create mycustomappname

and then it creates that heroku url

http://mycustomappname.herokuapp.com

and then when I push to heroku, the app is available at that custom domain.

However, after creating a canvas app on Facebook, and selecting Heroku to host, Facebook gave me the heroku url. I have a rails app on my local host. How do I push to that specific heroku url if it wasn’t created from within the Rails console?

Answer 1

Run this from the console:

heroku git:remote -a <heroku url>

This will add a remote for the heroku url to your git config. See also this article.
