资源说明：Playing with the MOVE architectural concept
MOVE ==== This is an attempt to put-to-code some of the concepts described in: * Time to MOVE On: http://cirw.in/blog/time-to-move-on * Architecture, The Lost Years: http://www.confreaks.com/videos/759-rubymidwest2011-keynote-architecture-the-lost-years * http://collectiveidea.com/blog/archives/2012/06/28/wheres-your-business-logic/ The big idea is that it decomposes the application into Models, Views, and Operations instead of Models, Views, and Controllers. What's the difference? In my understanding (and experience thus far) this seperation (like MVC) keep views and models from knowing anything about each other. Unlike MVC, it does away with the ambiguous "Controller" and encourages "Operations" instead. Operations are essentially your high level use-cases in code form. It's still a cloudy thing in my brain. That's why I'm writing code. I can't say that I've reached any sort of enlightenment so far but there are a view incidental things here that I like: DataModelOperations is a protocol describing all of the things I do to my data model. WebApplicationState implements this protocol and provides an in-browser datastore. The server side could have an implementation of this protocol that stored data in MySQL instead. That's pretty cool. ViewOperations is a protocol describing all of the things I do to my global view. From the perspective of my operations, I've found it to be quite useful to think of my view as a monolithic thing--basically the whole browser window. My ViewOperations protocol (I'm pretending to write a todo list) exposes high-level concepts like "set-list-title" and emits high level events like "create-clicked". Since the view is fat and global, events can be global too. That's convenient. Hasn't bitten me yet though I'm wary. For testing, I can mock out my monolithic view and fire those high level events myself. make-noop-view does just that.
