在Rails项目中，我们将所有常量定义放在config / environment.rb中，将更多特定定义放在config / environments / development.rb中？

Question

Is that the usual convention? The more general constants in config/environment.rb , and more particular ones, such as HOST_NAME for development mode in config/environments/development.rb as localhost:3000 , in config/environments/production.rb as www.mygreatwebsite.com , and they will automatically get included into the project?

Answer 1

The config files test/production/development.rb are used when the rails application is started in one of these specific environments (test/production/development). The config.rb is used to define configuration which applies to all environments.
