heroku open - no app specified

Question

I\'ve just created a simple Rails app using

rails new myapp

then created the heroku stack using:

heroku create --stack ced         


        

Answer 1

Heroku by default is not creating app with your directory name, so when you do

heroku create --stack cedar
Creating calm-bayou-3229... done, stack is cedar
http://calm-bayou-3229.herokuapp.com/ | git@heroku.com:calm-bayou-3229.git

it is creating application named 'calm-bayou-3229' And you can do

heroku open --app calm-bayou-3229
Opening http://calm-bayou-3229.herokuapp.com/

You can always list your apps with:

heroku apps
