🌐 Manage Environment‑Specific Credentials

Rails lets you maintain separate credentials per environment, so you can have different keys for development, test, and production. Simply set RAILS_ENV when editing.

# Edit production credentials instead of development
RAILS_ENV=production EDITOR="nano" bin/rails credentials:edit

This command updates config/credentials/production.yml.enc. In your code, you still use:

Rails.application.credentials.dig(:payment_gateway, :api_key)

Rails automatically picks the right credentials file based on Rails.env.
