Ruby on rails and Heroku problem

You haven't committed anything to push yet. Try doing:

$ git add -A$ git commit

Then try to push to Heroku again.

You might try following along with this tutorial, although I can't vouch for it. Most of the professional endeavors in this space are books.

ruby-on-rails git heroku

If you want your commits to be easier to track in the future, after

$ git add -A

instead of

$ git commit

you can use

$ git commit -m "add a message here such as FIRST COMMIT or PROBLEM WITH CONTACTS VIEW ADDRESS VARIABLE TYPO FIXED."

3.Then you can

$ git push heroku master
