路由错误没有路由匹配

Question

我试图让用户从他的个人资料（user_path）可以注册他的车辆（new_user_car_path）。但我得到这个错误：

Routing Error 
No route matches {:action=>"new", :controller=>"cars"} 

的，我有未来的routes.rb

Estaciones::Application.routes.draw do 
root :to => "static_pages#home" 
match '/contact', :to=>'static_pages#contact' 
match '/about', :to=>'static_pages#about' 
devise_for :users 
resources :users do 
resources :cars, :only => [:new, :create, :edit, :destroy] 
end 

这里是user_path的一部分

<div class="container"> 

    <fieldset> 
    <h1><%= @user.email %></h1> 
    <br> 

    <h2>options</h2> 
    <p> 
    <strong>new car registration</strong> 
    <%= link_to "Sign up now!", new_user_car_path, :class => "btn btn-primary" %> 

    </p> 
    <p> 
    <strong>all cars view</strong> 

    </p> 
    </fieldset> 
</div> <!-- /container --> 

和我CarsController

class CarsController < ApplicationController 
    def new 
     @car = Car.new 
    end 

    def create 
     @car = current_user.cars.build(params[:car]) 
     if @car.save 
      redirect_to current_user, :flash => { :success => "car created!" } 
     else 
      redirect_to new_user_car_path, :flash => { :success => "sorry try again" } 
     end 
    end 
end

您需要将信息传递给路由，以便它可以确定去哪里。

如果要为用户创建新车，则需要传递用户。否则轨道将不知道从哪里得到用户......如果您想了解更多的一秒钟，这将是合乎逻辑的...

new_user_car_path(user)
