rail＆devise，route to home＃使用after_sign_in_path_for登錄後顯示

Question

登錄後，我想要路由到我的家庭＃索引，但它會生成/ home /：id請求並因此路由到主頁＃show 。

有人可以幫忙看看，點擊登錄按鈕後，我是否可以路由到索引。

非常感謝。

會話/ new.html.erb

    def new 
    @home = Home.new 
    respond_with(@home) 
    end 

    def edit 
    end 

    def create 
    @home = Home.new(home_params) 
    @home.save 
    respond_with(@home)

    def update 
    @home.update(home_params) 
    respond_with(@home)

    private 
    def set_home 
     @home = Home.find(params[:id])

    def home_params 
     params[:home] 
    end

Answer 1

您想登入重定向後homes#index但你對after_sign_in_path_for(resource)方法路徑已home_path(resource)它會重定向到homes#show

看看這個（你的耙路輸出）

-> homes GET /homes(.:format)    homes#index 
-> home GET /homes/:id(.:format)   homes#show 

homes_path名爲幫手路徑/homes with controller＃action is homes#index

home_path(id) is n艾湄有助於爲路徑/home/:id與控制器＃動作homes#show

http://guides.rubyonrails.org/routing.html#path-and-url-helpers

試試這個：

如果您有多個設備型號

class ApplicationController < ActionController::Base 

private 

def after_sign_in_path_for(resource) 
    if resource.is_a?(YourDeviceModel) 
     homes_path 
    else 
     another_path 
    end 
end 
end 

如果你有一個設備型號

class ApplicationController < ActionController::Base 

    private 

    def after_sign_in_path_for(resource) 
     homes_path 
    end 

end 

對你的評論問題

問：沒有s，它會路由到顯示方法嗎？

它可能並不總是如此，你有resources :homes你的routes.rb它可以生成路由默認的軌道。您可以閱讀這http://guides.rubyonrails.org/routing.html

Answer 2

應用程序/控制器/ application_controller.rb

class ApplicationController < ActionController::Base 

    def after_sign_in_path_for(resource) 
    home_path 
    end 

end 

配置/ routes.rb中

Rails.application.routes.draw do 
    get 'home', to: "home#index", as: :home 
end 

應用程序/控制器/ home_controller.rb

class HomeController < ActionController::Base 
    def index 
    end 
end 

當你在Rails中指定一個靜態路由時，你可以說你想要使用哪個HTTP動作，然後是你想要轉發請求的控制器＃動作，然後是你想要設置的_path名稱。

在你的情況下，你指定你想將登錄用戶發送到home_path，所以我們通過as：param設置home_path。
