How do I manage environment-specific settings in Rails?

How do I manage environment-specific settings in Rails?

In Rails, you can manage environment-specific settings using the config directory. Each environment (development, test, production) has its own configuration file.

Can you give me an example of how to set a database URL for production?

Sure! In config/database.yml, you can set the production database URL like this:

production:
  adapter: postgresql
  encoding: unicode
  database: myapp_production
  username: myapp
  password: <%= ENV['MYAPP_DATABASE_PASSWORD'] %>
  host: localhost

What if I want to use different API keys for each environment?

You can use environment variables for that. In your config/application.rb, you can access them like this:

config.api_key = ENV['API_KEY']

Is there a way to load different settings based on the environment?

Yes! You can create a config/initializers file for each environment and load specific settings there.
