Question

我正在制作一个网页，其中包含一个用户可以注册赢取iPad的页面。我创建了一个模型ipad.rb和一个ipads_controller.rb，并且在名称，电子邮件和Twitter处理的迁移中有三列。当Rails没有自动创建路由时我感到很惊讶（我认为它应该始终这样做）。

我在路线文件中添加了这个

resource :ipad
  match '/signup',  :to => 'ipads#new'

当我尝试创建注册表单时，在完全填写之前收到此错误消息

undefined method `ipads_path' for #<#<Class:0x00000103a64ec0>:0x00000103a49aa8>

这令我感到惊讶，因为它为何复数？

到目前为止，我只在new.html.erb和模型ipad.rb中创建了一个表单，并在ipads_controller.rb new和create中创建了两个操作。

谁能看到我做错了什么？即为什么Rails认为我需要一种方法ipads_path。另请注意，我创建了一个模型IPad.rb但删除了它并进行了迁移。

new.html.erb

<h1>Win an iPad</h1>

<h1>Sign up for iPad</h1>

<%= form_for(@ipad) do |f| %>
  <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.text_field :email %>
  </div>

  <div class="actions">
    <%= f.submit "Sign up" %>
  </div>
<% end %>

ipad.rb

class Ipad < ActiveRecord::Base

attr_accessible :name, :email, :twitter

email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

validates :name, :presence => true,
                 :length   => { :maximum => 50 }
validates :email, :presence => true,
                  :format   => { :with => email_regex }, 
                  :uniqueness => true

end

ipads_controller.rb

class IpadsController < ApplicationController

  def new
    @ipad = Ipad.new
    @title = "iPad Contest"
  end

  def create
    @ipad = Ipad.new(params[:ipad])
    if @ipad.save
      # Handle a successful save.
    else
      @title = "iPad Contest"
      render 'new'
    end
  end


end

的routes.rb

Enki::Application.routes.draw do
  namespace 'admin' do
    resource :session

    resources :posts, :pages do
      post 'preview', :on => :collection
    end
    resources :comments
    resources :undo_items do
      post 'undo', :on => :member
    end

    match 'health(/:action)' => 'health', :action => 'index', :as => :health



    root :to => 'dashboard#show'
  end

  resources :archives, :only => [:index]
  resources :pages, :only => [:show]

  resource :ipad
  match '/signup',  :to => 'ipads#new'

  constraints :year => /\d{4}/, :month => /\d{2}/, :day => /\d{2}/ do
    get ':year/:month/:day/:slug/comments'  => 'comments#index'
    post ':year/:month/:day/:slug/comments' => 'comments#create'
    get ':year/:month/:day/:slug/comments/new' => 'comments#new'
    get ':year/:month/:day/:slug' => 'posts#show'
  end

  scope :to => 'posts#index' do
    get 'posts.:format', :as => :formatted_posts
    get '(:tag)', :as => :posts
  end

  root :to => 'posts#index'
end

您的资源＆＃39; ipad＆＃39;在路线中应该是复数，即

资源：ipads

Rails：带有iPad.rb模型和ipads_session控制器的`ipads_path'错误消息
