Do Heroku pipeline stages correspond to Rails environment stages?

I just created my first Heroku pipeline and deployed a Rails app to its development stage.

My question is, do these pipeline stages (like development and production) correspond to the environments in Rails? For example, does my app deployed to the development stage get its settings from config/development.rb? Or do all apps deployed in Heroku read from production.rb regardless of pipeline stage?

I know it seems like a basic question but I couldn't find info in the docs or here. Thanks in advance.

Solution

  • If you go to settings -> reveal config vars, there should be an env variable called RAILS_ENV, which you can set to the environment you want. By default it is production.
