I have this RoR app that calls to RAILS_ROOT. When running it using rails server (or when checking with ./script/console
) the value contains the app's root. When deploying and running it with Heroku, however (or when checking with heroku console
), the returned path is '/app'.
Why's that?
Thanks
Because on heroku your app is in the /app
folder (from the root /
). It is NOT the app folder of your application, which is /app/app
.
The file structure is:
/app/app/...
/app/config/..
/app/Gemfile
...
You can make an experiment.
Run heroku console and discover the file structure.
> heroku console
> puts `ls`
> puts `pwd`
