Question

在我的应用程序上我有这个我正在尝试创建一个以前注册用户的汽车但是我得到了错误（tittle post）这是我的汽车控制器

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

    def create
      @user = User.find(params[:user_id])
      @car = @user.car.create(params[:car])
      redirect_to user_path(@user)
    end
end

这是我的route.rb

Estaciones::Application.routes.draw do
devise_for :users

root :to => "user#index"
resources :user do
   resources :cars
end

get "user/new"
post "user/create"
get "user/:id" => "User#show"
get "user/:user_id/car/new"

这是我的html.erb

的一部分

<div class="container">

  <h1>new user registered</h1>

  <p>
    <strong>name:</strong>
    <%= @user.name %>
  </p>

  <p>
    <strong>email:</strong>
    <%= @user.email %>
  </p>

  <h2>new car registration</h2>

  <%= form_for([@user, @user.car.build]) do |f| %>
    <p>
      <%= f.label :brand %><br />
      <%= f.text_field :brand %>
    </p>
    <p>
      <%= f.label :color %><br />
      <%= f.text_field :color %>
    </p>
    <p>
      <%= f.label :model %><br />
      <%= f.text_field :model %>
    </p>
    <p>
      <%= f.label :year %><br />
      <%= f.text_field :year %>
    </p>
    <p>
      <%= f.submit "Create new car"%>
     </p>
  <% end %>
</div>

当我提交新车的创建时，我收到了下一个错误

No route matches [POST] "/user/1/cars"

任何想法？

也是我的路线：

Answer 1

我不是铁杆人的红宝石。但.... 您的帖子网址/users/1/cars与您在route.rb文件中提及的任何路由都不匹配。

Answer 2

尝试这样做：

root :to => "user#index"
resources :users do
  resources :cars
end

取而代之的是：

root :to => "user#index"
resources :user do
  resources :cars
end

（向用户添加s）。并尝试去这里：/ users / 1 / cars

Answer 3

问题是因为resources :user是单数，但路线想要复数。路线应该是：

resources :users do
  resources :cars
end

没有路线匹配[POST]“/ user / 1 / cars”
