rails-new 命令

常用示例

说明

rails new creates a new Ruby on Rails application with the standard directory structure, configuration files, and dependencies. It generates everything needed to start developing a web application immediately. The command creates directories for models, views, controllers, tests, and configurations. It initializes a Gemfile with common dependencies, sets up database configuration, and optionally initializes a git repository. Rails applications follow convention over configuration. The generated structure establishes conventions that other Rails commands and the framework expect, enabling features like automatic routing and model discovery.
