For Rails add use the middleware in application.rb:

Rack::EnvNotifier
can display a custom notification on every html page. It can be configured:
Rack::EnvNotifier.notify = Rails.env.production?
or

The notification message is wrapped by #env-notifer
CSS ID. This can be customized using custom CSS.
To disable default CSS and use a custom one, configure the initializer:
Rack::EnvNotifier.custom_css = true
and define the custom CSS:
#env-notifier { font-size: 16px; } /* Rack::EnvNotifier.message = 'development' */ #env-notifier.development { background: #369; color: #fff; } /* Rack::EnvNotifier.message = 'watch out! production environment!!!' */ #env-notifier.watch-out-production-environment { background: #8a0000; color: #fff; font-weight: bold; }
Notification message¶ ↑
Rack::EnvNotifier.message = "development mode"
The default message is configured in the initializer:
case Rails.env when "development" Rack::EnvNotifier.message = "safe environment" when "staging" Rack::EnvNotifier.message = "qa environment" else Rack::EnvNotifier.message = "hot environment" end
Rails Sample Initializer¶ ↑
