对于model是全部放在model下面,还是应该分开包来管理的疑问

ruby和rails的文章看了不少.不过都没有看到过讲述如何在rails下面,按模块来分类model的资料(比如像java那样用包来分类java文件,呵呵 ...我是一个java程序员).

我也试了一下把不同功能的model放在model(rails默认的)文件夹下面的子文件夹(模块,也是包),也是可以成功的,不过这样做的话,rails的约定高于配置就用不上了,因为要自己指定各个类的class.比如:

has_one :my_test,:class_name => 'Content::MyTest'

 这样.

我觉得这样比较不爽.

另外,

include Human

这样的代码在model和controller里面似乎并不起它就有的作用.比如:我有一Human::User的类,在controll入er里面加

include Human

User.new

 这样的代码就会出错,提示也就是说找不到User类云云....

最后的感觉就是,rails的约定优于配置思想,确实是还来了好多方便,不过有时候未免不能随心所欲.

呵呵 ...... 也许是我强求了.

# migration script:

    drop_table :books

  Demo::Public Create (0.000635)   INSERT INTO publics ("name") VALUES('O''Reilly')
  Demo::Book Create (0.000202)   INSERT INTO books ("title", "public_id") VALUES('Ruby CookBook', 1)
=> true

 class Demo1::Public < ActiveRecord::Base  
  has_many :books  
 end  
 class Demo2::Book < ActiveRecord::Base  
  belongs_to :public  
 end

#test_controller.rb
class  Test < ApplicationController
include Demo1
  def index
        @book = Book.new
  end

end

  @book = Demo1::Book.new

@book = Demo1::Book.new
