Question

登录或注册后，应将用户重定向到其各自的展示页面。我正在使用Hartl指南中的一些代码，但我似乎无法让它工作：

控制器：

class UsersController < ApplicationController
    before_filter :authenticate_user!

  def show
    @user = User.find(params[:id])
  end

  def new
  end

  def create
    @user = User.new(user_params)
    if @user.save
        flash[:success] = "Welcome to the Sample App!"
      redirect_to @user
    else
      redirect_to login_path
    end
  end

private

    def user_params
      params.require(:user).permit(:name, :email, :password,
                                   :password_confirmation)
    end

end

路线：

  devise_for :users, :path => '', :path_names => { :sign_in => 'login', :sign_out => 'logout',
                                      :password => 'password', :confirmation => 'verification',
                                      :unlock => 'unblock', :registration => 'signup',
                                      :sign_up => 'new' }

  devise_scope :user do
    get   'login',        to: 'devise/sessions#new'
    get   "logout",       :to => "devise/sessions#destroy"
    get   "signup",       :to => "devise/registrations#new"
    get   "password", :to => "devise/passwords#new"
    match 'users/secret',   to: "devise/passwords#create",      via: :post
    match 'sessions/user',  to: 'devise/sessions#create',       via: :post
    match 'users/signup',   to: 'devise/registrations#create',  via: :post
  end

  resources :users
  resources :sessions    

  root 'home#index'

我的/views/users/show.html.erb只是一个简单的页面，直到我可以让重定向工作。

编辑：

rake routes

Answer 1

问题出在您的佣金路线输出的最后一行：

  root GET    /                            home#index

指向routes.rb

中的这一行

 root 'home#index'

您应该删除routes.rb中的该行，并将其替换为您想要的根路径。

在设计登录时，用户未被重定向到用户显示页面
