目录介绍
app/: 包含应用程序的主要代码，包括控制器、模型、视图和辅助方法。config/: 包含应用程序的配置文件，包括环境配置和初始化文件。db/: 包含数据库相关的文件，如迁移文件和种子数据。lib/: 包含自定义库和任务。public/: 包含静态文件，如图片、JavaScript 和样式表。test/: 包含测试文件，包括控制器、模型和测试辅助文件。Gemfile: 定义项目所需的 gem 依赖。Gemfile.lock: 锁定 gem 依赖的版本。README.md: 项目说明文档。
项目启动文件介绍
Combustion 项目的启动文件主要位于 config/ 目录下，其中最重要的是 config/application.rb 文件。
config/application.rb
该文件是应用程序的主配置文件，包含了应用程序的基本设置和加载路径。以下是该文件的基本结构：
require_relative "boot"
require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "active_storage/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_mailbox/engine"
require "action_text/engine"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"
require "rails/test_unit/railtie"
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module Combustion
class Application < Rails::Application
# Initialize configuration defaults for originally generated Rails version.
config.load_defaults 6.1
# Configuration for the application, engines, and railties goes here.
#
# These settings can be overridden in specific environments using the files
# in config/environments, which are processed later.
#
# config.time_zone = "Central Time (US & Canada)"
# config.eager_load_paths << Rails.root.join("extras")
end
end
项目配置文件介绍
Combustion 项目的配置文件主要位于 config/ 目录下，包括环境配置文件和初始化文件。
环境配置文件
环境配置文件位于 config/environments/ 目录下，包括 development.rb、test.rb 和 production.rb 等文件。
config/environments/development.rb
该文件包含开发环境的配置，例如：
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Do not eager load code on boot.
config.eager_load = false
# Show full error reports.
config.consider_all_requests_local = true
# Enable/disable caching. By default caching is disabled.
# Run rails dev
