remote rejected master -> master (pre-receive hook declined)

Question

I\'m working in rails 3.2 and I receive an error when I try to push to heroku:

 git push heroku master
Counting objects: 496, done.

Answer 1

I got the same error when I ran git status :

$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
  (use "git push" to publish your local commits)
nothing to commit, working directory clean

To fix it I can run:

$ git push and run 
$ git push heroku master
