# Merb::Router::Behavior::Proxy

Proxy catches any methods and proxies them to the current behavior. This allows building routes without constantly having to catching the yielded behavior object

:api: private

### Public Class Methods

new() click to toggle source

:api: private

    # File lib/merb-core/dispatch/router/behavior.rb, line 21
    def initialize
      @behaviors = []
    end

### Public Instance Methods

pop() click to toggle source

Removes the top-most behavior.

#### Notes

This occurs at the end of a nested scope (namespace, etc).

:api: private

    # File lib/merb-core/dispatch/router/behavior.rb, line 41
    def pop
      @behaviors.pop
    end

push(behavior) click to toggle source

Puts a behavior on the bottom of the stack.

#### Notes

The behaviors keep track of nested scopes.

:api: private

    # File lib/merb-core/dispatch/router/behavior.rb, line 31
    def push(behavior)
      @behaviors.push(behavior)
    end

redirect(url, opts = {}) click to toggle source

Generates a Rack redirection response.

#### Notes

Refer to Merb::Rack::Helpers.redirect for documentation.

:api: public

    # File lib/merb-core/dispatch/router/behavior.rb, line 139
    def redirect(url, opts = {})
      Merb::Rack::Helpers.redirect(url, opts)
    end

respond_to?(*args) click to toggle source

Tests whether the top-most behavior responds to the arguments.

#### Notes

Behaviors contain the actual functionality of the proxy.

:api: private

    # File lib/merb-core/dispatch/router/behavior.rb, line 51
    def respond_to?(*args)
      super || @behaviors.last.respond_to?(*args)
    end

url(name, *args) click to toggle source

There are three possible ways to use this method. First, if you have a named route, you can specify the route as the first parameter as a symbol and any paramters in a hash. Second, you can generate the default route by just passing the params hash, just passing the params hash. Finally, you can use the anonymous parameters. This allows you to specify the parameters to a named route in the order they appear in the router.

#### Parameters(Named Route)

name<Symbol> | The name of the route.
args<Hash> | Parameters for the route generation.

#### Parameters(Default Route)

args<Hash> | Parameters for the route generation. This route will use the default route.

#### Parameters(Anonymous Parameters)

name<Symbol> | The name of the route.
args<Array> | An array of anonymous parameters to generate the route with. These parameters are assigned to the route parameters in the order that they are passed.

#### Returns

String | The generated URL.

#### Examples

Named Route

Merb::Router.prepare do

    match("/articles/:title").to(:controller => :articles, :action => :show).name("articles")

end

url(:articles, :title => "new_article")

Default Route

Merb::Router.prepare do

    default_routes

end

url(:controller => "articles", :action => "new")

Anonymous Paramters

Merb::Router.prepare do

    match("/articles/:year/:month/:title").to(:controller => :articles, :action => :show).name("articles")

end

url(:articles, 2008, 10, "test_article")

:api: public

    # File lib/merb-core/dispatch/router/behavior.rb, line 128
    def url(name, *args)
      args << {}
      Merb::Router.url(name, *args)
    end
