Question

Is it possible to to target an app version in Heroku based on the current Git branch? In the Heroku docs, its specifies how to target a a specific version of the app.

# run command on 'production'    
$ heroku run rake db:migrate --remote production

To make things easier, you can use your git config to specify a
default app. For example, if you wanted “staging” do be your default
remote, you could set it with the following command:

$ git config heroku.remote staging

It would make sense to have the local development branch push to the development app and the local production branch push to the production app.

I’m not familiar with Heroku, but you could easily write a shell-script wrapper that would:

• Get the name of the current branch using git symbolic-ref --short HEAD
• Get the Heroku target by using git config heroku.<branch>.remote
• Run the appropriate command

This assumes that you manually configure a per-branch setting for heroku, e.g.:

git config heroku.master.remote production
git config heroku.develop.remote staging

This doesn’t do anything by itself; it’s just lets you read these values in a script using git config.
