ruby-on-rails – 什么是rails3应用程序构建器？

根据导轨使用情况：

$rails new --help
Usage:
  rails new APP_PATH [options]

Options:
  -b,[--builder=BUILDER]        # Path to a application builder (can be a filesystem path or URL)
      [--old-style-hash]         # Force using old style hash (:foo => 'bar') on Ruby >= 1.9
      [--skip-gemfile]           # Don't create a Gemfile

这个“应用程序构建器”引用了什么,它与应用程序模板(-m选项)的比较如何？

解决方法

Descriptions in API Doc

The application builder allows you to override elements of the
application generator without being forced to reverse the operations
of the default generator.

简而言之,您可以在创建新的rails应用程序之前定义默认的依赖关系集.
