Heroku rails console does not start any more

Question

I have an issue with running the rails console at heroku (cedar-stack). Each of the following commands heroku run console, heroku run rails console, heroku run bundle exec rails

Answer 1

If you have multiple environments (staging / production / etc) you need this command:

heroku run -a app-name console

If you only have a single environment and never setup staging or other environments you can just run:

heroku run console

Answer 2

I was with the same problem and I decided to do this and it worked

$ heroku run bash
$ cd bin
~/bin $ ruby rails console

Answer 3

For some reason you need to explicitly define the console process in the Procfile:

# Procfile

web: script/rails server -p $PORT
console: script/rails console

Answer 4

For Cedar Stack and later:

heroku run rails console --app <app name>

Previous stacks could use this command:

heroku run console --app <app name>

Answer 5

You should just use heroku run console as others have answered.

Heroku only runs in one environment at a time, which is configured by the RAILS_ENV and RACK_ENV environments variables.

When you connect, the console will use the correct environment automatically.
