Adding multiple heroku apps to a single repository different branches

heroku_multiple_remotes_multiple_branches

Suppose you have two heroku remote apps
myapp-dev & myapp-prod
and two git branches 
master(for dev) & production
Now lets setup heroku on the existing git repo in your local machine
Assuming the branches and the apps exist already
git remote add heroku-myapp-dev https://git.heroku.com/myapp-dev.git 
git remote add heroku-myapp-prod https://git.heroku.com/myapp-prod.git 


 git remote -v
 should show something like this
 heroku-myapp-prod	https://git.heroku.com/myapp-prod.git (fetch)
heroku-myapp-prod	https://git.heroku.com/myapp-prod.git (push)
heroku-myapp-dev	https://git.heroku.com/myapp-dev.git (fetch)
heroku-myapp-dev	https://git.heroku.com/myapp-dev.git (push)
origin	git@bitbucket.org:username/myapp.git (fetch)
origin	git@bitbucket.org:username/myapp.git (push)

Now if you want to push your master branch to a particular heroku app
git push heroku-myapp-prod master

To push the other branch(production being the other branch)
git push heroku-myapp-prod production:master

git push --force heroku-dev develop:master
