环境:ruby 1.9.2 + rails 3.0.3

rails console 用起来还是很爽的,路由也可以在console下使用 , 甚至可以 get , post , 下面介绍惯用手法:

1. rake 查看routes

    > rake routes
   

2. console 下查看 routes

    Rails.application.routes.routes # rails 2.x 使用 ActionController::Routing::Routes.routes
   

3. 查看 root(routes)

    ruby-1.9.2-p0 > app.root_path
     => "/"
    ruby-1.9.2-p0 > app.root_url
     => "http://www.example.com/"
    ruby-1.9.2-p0 > app.host = "www.wxianfeng.com"
     => "www.wxianfeng.com"
    ruby-1.9.2-p0 > app.root_url
     => "http://www.wxianfeng.com/"
   

4. 查看资源 路由

    ruby-1.9.2-p0 >   user = User.first
      User Load (0.3ms)  SELECT `users`.* FROM `users` LIMIT 1
     => #<User id: 1, login: "entos", name: "", email: "entos@entos.com", crypted_password: "3dea29b4e40bc9a70bb63678678c5ff37fe49753", salt: "2ec7e5db7f3ce5de61f1add8275b674dbd2770dc", remember_token: nil, remember_token_expires_at: nil, activation_code: nil, activated_at: nil, status: 2, suspend_at: nil, avatar_id: nil, orgunit_id: nil, mobile_phone: nil, last_login_at: nil, language: nil, options: nil, created_at: "2011-03-01 07:42:37", updated_at: "2011-03-01 07:42:37">
    ruby-1.9.2-p0 > app.user_path(user)
     => "/users/1"
    ruby-1.9.2-p0 > app.users_path
     => "/users"
    ruby-1.9.2-p0 > app.new_user_path
     => "/users/new"
    ruby-1.9.2-p0 > app.edit_user_path(:id=>user.id)
     => "/users/1/edit"
    ruby-1.9.2-p0 > app.users_url
     => "http://www.wxianfeng.com/users"
   

5. 不使用app调用

    ruby-1.9.2-p0 > include ActionController::UrlWriter
     => Object
    ruby-1.9.2-p0 > default_url_options[:host] = "wxianfeng.com"
     => "wxianfeng.com"
    ruby-1.9.2-p0 > users_url
     => "http://wxianfeng.com/users"
   

6. path 和 route Hash 互转

    ruby-1.9.2-p0 > r = Rails.application.routes
    ruby-1.9.2-p0 > r.generate :controller => "users" , :action=>"new"
     => "/signup"
    ruby-1.9.2-p0 > r.generate :controller => "users" , :action=>"edit" , :id=>1
     => "/users/1/edit"
    ruby-1.9.2-p0 > r.recognize_path "/users/index"
     => {:action=>"show", :controller=>"users", :id=>"index"}
    ruby-1.9.2-p0 > r.recognize_path "/users",:method=>"post"
     => {:action=>"create", :controller=>"users"}
   

7. get, post

   模拟get访问首页，没登录 然后跳转到了/login ， 然后 post 提交登录 成功

    ruby-1.9.2-p0 > app.class
     => ActionDispatch::Integration::Session
    ruby-1.9.2-p0 > app.get "/"
     => 302
    ruby-1.9.2-p0 > app.controller.params
     => {"controller"=>"welcome", "action"=>"index"}
    ruby-1.9.2-p0 > app.response.redirect_url
     => "http://www.example.com/login"
    ruby-1.9.2-p0 > app.post "/session" , {:login=>"entos",:password=>"netposa"}
      SQL (0.3ms)  SHOW TABLES
      User Load (0.2ms)  SELECT `users`.* FROM `users` WHERE (status = 2) AND (`users`.`login` = 'entos') LIMIT 1
      SQL (0.1ms)  BEGIN
      User Load (0.3ms)  SELECT `users`.* FROM `users` WHERE (`users`.`id` = 1) LIMIT 1
      SQL (0.0ms)  COMMIT
     => 302
    ruby-1.9.2-p0 > app.controller.params
     => {"login"=>"entos", "password"=>"netposa", "action"=>"create", "controller"=>"sessions"}
    ruby-1.9.2-p0 > app.session[:user_id]
     => 1
    ruby-1.9.2-p0 > app.cookies
     => #<Rack::Test::CookieJar:0xb010120 @default_host="www.example.com", @cookies=[#<Rack::Test::Cookie:0x9b726f0 @default_host="www.example.com", @name_value_raw="_ent_os_session=BAh7CEkiD3Nlc3Npb25faWQGOgZFRiIlMzM4ZTdhYzU4OTY3NDhmMmZmMGFhNDkyYTExZWVmOThJIgx1c2VyX2lkBjsARmkGSSIKZmxhc2gGOwBGSUM6JUFjdGlvbkRpc3BhdGNoOjpGbGFzaDo6Rmxhc2hIYXNoewY6C25vdGljZUkiG0xvZ2dlZCBpbiBzdWNjZXNzZnVsbHkGOwBUBjoKQHVzZWRvOghTZXQGOgpAaGFzaHsA--d8652cbfebcae436e64a824d7ac2f64a81aa6619", @name="_ent_os_session", @value="BAh7CEkiD3Nlc3Npb25faWQGOgZFRiIlMzM4ZTdhYzU4OTY3NDhmMmZmMGFhNDkyYTExZWVmOThJIgx1c2VyX2lkBjsARmkGSSIKZmxhc2gGOwBGSUM6JUFjdGlvbkRpc3BhdGNoOjpGbGFzaDo6Rmxhc2hIYXNoewY6C25vdGljZUkiG0xvZ2dlZCBpbiBzdWNjZXNzZnVsbHkGOwBUBjoKQHVzZWRvOghTZXQGOgpAaGFzaHsA--d8652cbfebcae436e64a824d7ac2f64a81aa6619", @options={"path"=>"/", "HttpOnly"=>nil, "domain"=>"www.example.com"}>, #<Rack::Test::Cookie:0x9b826f4 @default_host="www.example.com", @name_value_raw="auth_token=", @name="auth_token", @value="", @options={"path"=>"/", "domain"=>"www.example.com"}>]>
    ruby-1.9.2-p0 > app.response.redirect_url
     => "http://www.example.com/"
    ruby-1.9.2-p0 > app.flash
     => {:notice=>"Logged in successfully"}
    ruby-1.9.2-p0 >
   

   甚至 你还可以 ajax 异步提交

    >> app.xml_http_request "/store/add_to_cart", :id => 1
    => 200
   

8. 分配一个 实例变量

    >>app.assigns[:foo] = “bar”
