How to reset everything Heroku in my Git/Rails 3.1 Project

Question

I solved my problem while writing this post, but I thought this might be good information for other noobs like me :)

To solve the problem below edit the following file .git/config

There's a section that looks like this

[remote "heroku"]
url = [email protected]:adjective-noun-1234.git
fetch = +refs/heads/*:refs/remotes/heroku/*

This is what git tries to push to. Just change the line

url = [email protected]:adjective-noun-1234.git

to whatever new Heroku project you created. Git should now be able to push to Heroku again.

I have gotten my second Rails app ever to a working state and want to deploy it. So I followed all the steps for Heroku deployment in the Ruby on Rails Tutorial (I had the deployment working for the sample app from the book) using:

heroku create

I then push my project with

git push heroku master

The project doesn't work although I can't find any errors in the Heroku logs, all I get is:

We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly.

So I looked around the Heroku Support Section and found the official Rails 3.0 / 3.1 deployment guide:

http://devcenter.heroku.com/articles/rails3

http://devcenter.heroku.com/articles/rails31_heroku_cedar

I went to the Heroku Web Frontend > General Info > Destroy App because I wanted to continue my efforts with a clean slate.

Following the guide I created a Heroku project for the cedar stack:

heroku create --stack cedar

And push it to Heroku using

git push heroku master

THE PROBLEM: for some reason git is still trying to push to the old Heroku project!!!

resulting in an error

fatal: The remote end hung up unexpectedly

Answer 1

Check your remote repositories, and update it to the new heroku name:

git remote -v

Then remove the heroku one that is wrong:

git remote rm heroku

Then add the new one

git remote add heroku [email protected]:sitename.git
