Ruby on rails 轨道路由错误'；没有路由匹配'；

因此，我一直遇到以下错误：

没有路由匹配{:action=>“show”，:controller=>“users”}

我尝试运行rake路由，我可以看到该路由存在：

 user         GET          /users/:id(.:format)       users#show
              PUT          /users/:id(.:format)       users#update
              DELETE       /users/:id(.:format)       users#destroy

但是每次我尝试访问页面

“/users/1”

（1是用户id），我都会遇到上述错误。有什么想法吗？谢谢

这是我的

路线。rb

：

SampleApp::Application.routes.draw do
  root to: 'static_pages#home'

  resources :users
  resource :sessions, only: [:new, :create, :destroy]


  match '/signup',  to: 'users#new'
  match '/signin',  to: 'sessions#new'
  match '/signout', to: 'sessions#destroy', via: :delete

  match '/help',    to: 'static_pages#help'
  match '/about',   to: 'static_pages#about'
  match '/contact', to: 'static_pages#contact'

class UsersController < ApplicationController

  before_filter :signed_in_user, only: [:index, :edit, :update]
  before_filter :correct_user,   only: [:edit, :update]

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

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to the Paper Piazza!"
      redirect_to @user
    else
      render 'new'
    end
  end

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

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

  def index
    @users = User.paginate(page: params[:page])
  end

  private

    def signed_in_user
      unless signed_in?
        store_location
        redirect_to signin_path, notice: "Please sign in."
      end
    end

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

这是我的

用户\u控制器.rb

：

SampleApp::Application.routes.draw do
  root to: 'static_pages#home'

  resources :users
  resource :sessions, only: [:new, :create, :destroy]


  match '/signup',  to: 'users#new'
  match '/signin',  to: 'sessions#new'
  match '/signout', to: 'sessions#destroy', via: :delete

  match '/help',    to: 'static_pages#help'
  match '/about',   to: 'static_pages#about'
  match '/contact', to: 'static_pages#contact'

class UsersController < ApplicationController

  before_filter :signed_in_user, only: [:index, :edit, :update]
  before_filter :correct_user,   only: [:edit, :update]

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

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to the Paper Piazza!"
      redirect_to @user
    else
      render 'new'
    end
  end

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

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

  def index
    @users = User.paginate(page: params[:page])
  end

  private

    def signed_in_user
      unless signed_in?
        store_location
        redirect_to signin_path, notice: "Please sign in."
      end
    end

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

class UsersController

尝试修复打字错误：

root :to 'static_pages#home'

（而不是

根目录：

），并将其移动到块的最后一行。如果有什么不同，请告诉我

奇怪的是，我构建了一个新项目，其中包含一个路由文件，该文件的内容如下：

RoutingTest::Application.routes.draw do
  resources :users
  root :to => "static_pages#home"
end

当我在控制台中运行此命令时，出现了与您看到的相同的错误：

>> r = Rails.application.routes ; true
=> true
>> r.recognize_path("/users/1")
=> ActionController::RoutingError: No route matches "/users"

。。。但当我在一个稍旧的项目中运行相同的东西时，我得到：

>> r = Rails.application.routes ; true
=> true
>> r.recognize_path("/users/1")
=> {:action=>"show", :controller=>"users", :id=>"1"}

---

所以我没有信心我告诉你的事情会有所不同。（除此之外，Rails.application.routes技巧对于验证控制台中的路径非常有用！）

我有一个类似的问题，我有一些只返回根页面的路由，但会显示在

rake routes

中。根据一位特定名称空间和所有路由的开发人员的说法，

根到：（路由）

必须始终是最后一个。这与Rails路由指南（请参阅）相矛盾，该指南规定，对root的任何调用都应该位于文件的顶部。这对我来说绝对不管用。有趣的…

显示您的路线。rb文件不，

/users/1/

似乎不起作用。您是否有

用户控制器。rb

？是的，我也会发布。这就是您遇到的错误吗？这个问题有关系吗？小心保留的名字。试着不要使用静态页面，看看你得到了什么。

root to:'static_pages#home'

是正确的语法，
