1.Action Pack: Resources
map.namespace(:admin) do |admin|
admin.resources :products,
:collection => { :inventory => :get },
:member => { :duplicate => :post },
:has_many => [ :tags, :images, :variants ]
end
2. Action Pack: HTTP Loving
class PostsController < ApplicationController
USER_NAME, PASSWORD = "dhh", "secret"
before_filter :authenticate, :except => [ :index ]
def index
render :text => "Everyone can see me!"
end
def edit
render :text => "I'm only accessible if you know the password"
end
private
def authenticate
authenticate_or_request_with_http_basic do |user_name, password|
user_name == USER_NAME && password == PASSWORD
end
end
end
3. Action Pack: Exception handling
大多数常见的异常都可以统一处理，而不是每个需要单独的处理。通常情况下，你只需要覆盖rescue_action_in_public方法，来进行统一的异常处理即可。但是你也有可能需要使用自己的case语句来处理特定场合的异常。因此我们现在提供了一个类级别的宏叫做rescue_from，你可以使用它来声明针对某个特定的Action来捕获异常
class PostsController < ApplicationController
rescue_from User::NotAuthorized, :with => :deny_access
protected
def deny_access
...
end
end
