如果使用 rvm安裝ruby 則 gem安裝於 ~/.rvm/.gem下面

rails也是一個gem

1. rails s 命令列可以展示每個請求的請求模組和profile資訊.

請求首頁. 首先訪問: routes.rb

root ‘home#index‘
resources :roles

路由至: home_controller.rb

skip_before_filter :authenticate_user! // 跳過使用者認證
skip_authorization_check// 跳過使用者認證
before_action :redirect_to_login_if_in_subdomain // 如果是次層網域, 跳轉到登陸介面

def index
end

index函數為空白, 直接尋找 views/layouts/home.html.erb -> views/home

不同action 根據action 來做一些樣式的改變.

http://localhost:3000/login

請求登陸介面: routes.rb

get "/login" => "sessions#new"

devise.sessions_controller

prepend_before_filter :require_no_authentication, only: [ :new, :create ]
prepend_before_filter :allow_params_authentication!, only: :create
prepend_before_filter only: [ :create, :destroy ] { request.env["devise.skip_timeout"] = true }

# GET /resource/sign_in
def new
self.resource = resource_class.new(sign_in_params)
clean_up_passwords(resource)
respond_with(resource, serialize_options(resource))
end
