前面的章节提到Rails Engine实现了Rails中著名的 Convention over Configuration. Code Loading of Rails. Ruby on Rails中实现了一套复杂的代码加载机制，比如怎样自动加载对应的模型，在开发模式 如何重新加载整个项目的代码，以及开发模式下的代码预加载。 Ruby on Rails开发者一般不需关心这样一个问题，从来没有手动加载某个模型类或者控制器类，但为什么这个类可以直接使用呢 其中的秘密就是Rails使用了Ruby的其中一个Meta Programming功能，. Dependencies.load missing constant. Dependencies.search for file. Dependencies.require or load. 而重新加载的机制，同样是利用Ruby语言的Meta Programming，通过 remove const. 和 say with time. Index taggings on tag id.

ActiveRecord 对象的拼装 - The Kai Way
http://thekaiway.com/2013/07/26/assemble-ar-object
这些对象是怎样构造拼装出来的, 它们持有哪些状态，并且怎样持有状态的呢 这就是本文要讨论的内容。 AR对象有两种状态, 要么是已经持久化, 要么还未持久化。 查询的方式得到的结果AR对象, 都是已持久化状态的, 都通过. 发送查询到数据库 bla bla bla. 方法构造出来AR对象, 即未持久化的, 都通过. 标记都为false, 因为你不可能查询出一个不存在的AR对象, 也不可能创建还未持久化就被删除的AR对象。 这个标记, 它的状态变化只通过两个API能改变,. 当然除了持久化之外, AR对象还带上了许多其他的状态, 比如监控属性改变内容的状态, 上下文的事务状态, 是否只读状态等。 AR对象出于效率考虑加上缓存, 比如关联对象的缓存, 属性的缓存等。 这些状态, 无论怎么途径构建出来, 都会统一通过. AR对象, 为了实现两次查询出同一条数据库记录可以判等, 它还覆写了. 也就是只要是同一个模型, 且数据库记录的主键是一致的, 则认为它们是等同的。 Posted by Kai Chen. 写作 积累 快乐 ». Read and Write Activerecord Attribute.
