Question

我使用resources :users创建了一个包含路径的用户模型，但无法通过链接显示各个用户个人资料。下面的索引页面显示列表中的所有用户：

用户/ index.html.erb

<% provide(:title, 'All drivers') %>
<h1>All drivers</h1>

<ul class="center hero-unit col-md-6 col-md-offset-3 users">
  <% @users.each do |user| %>
    <div class="user-name">
    <li><%= link_to user.name, user %></li>
    </div>
  <% end %>
</ul>

但是当我点击索引页面上的用户（比如用户3）时，它会将我发送到/ users / 3。这个页面给了我这个错误：

No route matches {:action=>"edit", :controller=>"users", :id=>nil} missing required keys: [:id]但链接转到/ users / 3并传递参数{“id”=＆gt;“3”}。那么id怎么可以为零呢？我不明白如何让这些链接正常工作。

users.controller.rb

class UsersController < ApplicationController
  #add before action for index
  before_action :correct_user, only: [:edit, :update]

    def index
      @users = User.all
    end

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

    def new
      @user = User.new
    end

    def create
      @user = User.new(user_params)
      if @user.save
        log_in @user
        flash[:success] = "Thank you for signing up, welcome to ensage!"
        redirect_to root_path
      else
        render 'new'
      end
    end

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

    def update
      @user = User.find(params[:id])
      if @user.update_attributes(user_params)
        flash[:success] = "Profile updated"
        redirect_to @user
      else
          render 'edit'
      end
    end

    private

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

    def correct_user
      @user = User.find(params[:id])
      redirect_to(root_url) unless current_user?(@user)
    end
end

的routes.rb

Rails.application.routes.draw do

  get 'shop_sessions/new'

  get 'shops/new'

  get 'cars/new'

  get 'sessions/new'

  get 'users/new'

  root             'static_pages#home'
  get 'shophome' => 'static_pages#shop_home', as:"shop_home"
  get 'shop', to: 'static_pages#shop_home', as: 'shop_root'
  get 'shops', to: 'shops#index', as: 'shop_index'
  get 'help'    => 'static_pages#help'
  get 'about'   => 'static_pages#about'
  get 'contact' => 'static_pages#contact'
  get 'signup'  => 'users#new'
  get 'shopsignup' => 'shops#new'
  get    'login'   => 'sessions#new'
  post   'login'   => 'sessions#create'
  get    'shoplogin'   => 'shop_sessions#new', as: 'shop_login'
  post   'shoplogin'   => 'shop_sessions#create'
  delete 'logout'  => 'sessions#destroy'
  delete 'shoplogout'  => 'shop_sessions#destroy', as: 'shop_logout'

  resources :users
  resources :shops
  resources :cars,  only: [:create, :destroy, :edit]
end

用户/ show.html.erb

    <div class="row">
  <aside class="col-md-4">
    <section class="user_info">
      <h1>
        <%= @user.name %>
      </h1>
    </section>
  </aside>
  <div class="col-md-8">
    <% if @user.cars.any? %>
      <h3>Cars (<%= @user.cars.count %>)</h3>
      <ol class="cars">
        <%= render @cars %>
      </ol>
    <% end %>
  </div>
</div>
