在了解 Moutable之前， 先看这个视频：
http://railscasts.com/episodes/277-mountable-engines
了解Mountable Engines与Full Engines的区别， 看这篇文章:
http://stackoverflow.com/questions/6118905/rails-3-1-engine-vs-mountable-app
当我们使用：
rails plugin new uhoh –mountable
我们可以把这个创建好的plugin变成一个gem来使用。
比如我们可以先创建一个rails app
rails new with_engine -T -O -J
编辑Gemfile, 添加以下一行:
gem ‘uhoh’, :path => ‘/Users/weston/Downloads/277-mountable-engines/uhoh-after/’ #刚才创建的mountable 路径
执行
bundle install
vim config/routs.rb
添加以下一行:
mount Uhoh::Engine => "/uhoh", :as => "uhoh_engine"
这样我们就可以使用这个engines了…

可以参考：
http://stackoverflow.com/questions/1531514/observers-vs-callbacks

class Model < ActiveRecord::Base
before_update :disallow_bob
def disallow_bob
return false if model.name == "bob"
end
end
class ModelObserver < ActiveRecord::Observer
def before_update(model)
return false if model.name == "mary"
end
end
m = Model.create(:name => "whatever")
m.update_attributes(:name => "bob")
=> false — name will still be "whatever" in database
m.update_attributes(:name => "mary")
=> true — [...]

cc -c -o source.c target.o
或者可以把其做成lib
gcc -g -c source.c
ar -rc libsource.a source.o
