轨道上的红宝石 - 路由错误 "No route matches" 'new' 路径

Question

我有一个User模型和一个Storefront模型。

由于某种原因，当我尝试去/storefronts/new时，我得到这个错误:

路由错误没有匹配{:action=>"edit"，:controller=>"storefronts"的路由，:id=># Storefront id: nil, name: nil, user_id: 4, created_at: nil，Updated_at: nil, description: nil, location: nil>}

我花了3个小时想弄明白。它昨天还在工作……为什么它说:action=>"edit"当它是'new' action?

下面是我的代码:

class Storefront < ActiveRecord::Base
  attr_accessible :name, :location, :description
  belongs_to :user
end
class User < ActiveRecord::Base
  attr_accessible :name, :email, :password, :password_confirmation
  has_secure_password
  has_one :storefront
end
class StorefrontsController < ApplicationController
  before_filter :check_auth, only: [:new, :edit, :update]
  def index
    @storefronts = Storefront.all
  end
  def new
    @storefront = current_user.build_storefront
  end
  def create
    @storefront = current_user.build_storefront(params[:storefront])
    if @storefront.save
      redirect_to edit_storefront_path(@storefront)
    else
      render 'new'
    end
  end
def show
    @storefront = Storefront.find(params[:id])
  end
  def edit
    @storefront = Storefront.find(params[:id])
  end
  def update
    @storefront = Storefront.find(params[:id])
    if @storefront.update_attributes(params[:storefront])
      redirect_to @storefront
    else
      render 'edit'
    end
  end
end

Pbf::Application.routes.draw do
  resources :sessions, :only => [:new, :create, :destroy]
  resources :users
  resources :storefronts
  root :to => 'storefronts#index'
  match '/signup',  to: 'users#new'
  match '/login', to: 'sessions#new'
  match '/logout', to: 'sessions#destroy'
end

使用<<p>链接我strong>(的问题):

  <% if current_user.storefront %>
    <%= link_to "Manage Storefront", edit_storefront_path(current_user.storefront) %>
  <% else %>
    <%= link_to "Open Storefront!", openstore_path %>
  <% end %>

提前感谢!

编辑:我的rake routes

   sessions POST   /sessions(.:format)             sessions#create
new_session GET    /sessions/new(.:format)         sessions#new
    session DELETE /sessions/:id(.:format)         sessions#destroy
      users GET    /users(.:format)                users#index
            POST   /users(.:format)                users#create
   new_user GET    /users/new(.:format)            users#new
  edit_user GET    /users/:id/edit(.:format)       users#edit
       user GET    /users/:id(.:format)            users#show
            PUT    /users/:id(.:format)            users#update
            DELETE /users/:id(.:format)            users#destroy
storefronts GET    /storefronts(.:format)          storefronts#index
            POST   /storefronts(.:format)          storefronts#create  
new_storefront GET    /storefronts/new(.:format)   storefronts#new 
edit_storefront GET    /storefronts/:id/edit(.:format) storefronts#edit
 storefront GET    /storefronts/:id(.:format)      storefronts#show
            PUT    /storefronts/:id(.:format)      storefronts#update
            DELETE /storefronts/:id(.:format)      storefronts#destroy

Answer 1

在我看来你的视图中有一个错误。app/views/storefronts/new.html.erb错误地引用edit_storefront_path而没有传递storefront_id作为参数。你可能需要storefronts_path

Answer 2

问题可能是路由器无法从某种':id'中找出'new'。尝试在编辑路由声明中添加约束

get 'storefronts/:id/edit' => 'storefronts#edit', :id => /[d]*/

那么只有数字id将被解释为编辑操作的调用。

Answer 3

这是new_storefronts_path，它是集合路由，如果你传递的是单数形式，那么如果你没有声明任何命名路由，它就被认为是成员路由。这就是为什么路由选择编辑动作，关于id 4，你没有按照约定传递id，所以nil.object_id是4。
