Every time I push my app to heroku I see the line
-----> Launching... done, v43
Why would you want to depend on running a command after every push? The accepted answer is worse than setting the config yourself.
Instead add to your Gemfile:
Add your App name and API key to the Heroku config:
$ heroku config:add HEROKU_APP_NAME=myapp HEROKU_API_KEY=bp6ef3a9...
Then put something like this in
unless (app_name = ENV["HEROKU_APP_NAME"]).nil? require 'heroku-api' heroku = Heroku::API.new(:api_key => ENV["HEROKU_API_KEY"]) release = heroku.get_releases(app_name).body.last ENV["HEROKU_RELEASE_NAME"] = release["name"] end
puts ENV["HEROKU_RELEASE_NAME"] => v42
Now it's fully automated. You can forget about it and continue to work on your app.
