ruby-on-rails – Rails路由错误？ “没有路线匹配”

所以我不断遇到以下错误：

No route matches {:action=>"show",:controller=>"users"}

我尝试运行耙子路线,我可以看到路线存在：

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

但是每次尝试访问页面“/ users / 1”(1是用户ID)时,我得到上面的错误.有任何想法吗？谢谢！

这是我的routes.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'

这是我的users_controller.rb：

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

解决方法

尝试修复打字错误：

root :to 'static_pages#home'

(而不是根到:),并将其移动到块的最后一行.让我知道这是否有所作为！

很奇怪的是,我用一个路由文件创建了一个新的项目,只需读取：

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

当我在控制台中运行这个操作时,我遇到了同样的错误：

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

…但是当我在一个稍旧的项目中运行相同的事情时,我得到：

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

所以我几乎没有信心我所告诉你会有所作为. (除此之外,Rails.application.routes技巧对于验证控制台中的路径非常有用！)
