Rails Edit Form
问题
当我想进入编辑页面时，我一直在遇到这个错误：“NO ROUTE MATCHES”，但奇怪的是，当我将 **order = @order** 更改为 **@order.listing** 时，一切都正常，但没有信息可供编辑，我已经为这个错误苦恼了一段时间。
**这是我的 Orders 控制器：**
```ruby
class OrdersController < ApplicationController
before_action :set_order, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!
# GET /orders
# GET /orders.json
def index
@orders = Order.all
end
# GET /orders/1
# GET /orders/1.json
def show
end
# GET /orders/new
def new
@order = Order.new
@listing = Listing.find(params[:listing_id])
end
# GET /orders/1/edit
def edit
end
# POST /orders
# POST /orders.json
def create
@order = Order.new(order_params)
@listing = Listing.find(params[:listing_id])
@seller = @listing.user
@order.listing_id = @listing.id
@order.buyer_id = current_user.id
@order.seller_id = @seller.id
respond_to do |format|
if @order.save
format.html { redirect_to root_url, notice: 'Pedido creado' }
format.json { render :show, status: :created, location: @order }
else
format.html { render :new }
format.json { render json: @order.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /orders/1
# PATCH/PUT /orders/1.json
def update
respond_to do |format|
if @order.update(order_params)
format.html { redirect_to @order, notice: 'El pedido fue actualizado' }
format.json { render :show, status: :ok, location: @order }
else
format.html { render :edit }
format.json { render json: @order.errors, status: :unprocessable_entity }
end
end
end
# DELETE /orders/1
# DELETE /orders/1.json
def destroy
@order.destroy
respond_to do |format|
format.html { redirect_to orders_url, notice: 'El pedido fue eliminado con exito' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_order
@order = Order.find(params[:id])
end
# Only allow a list of trusted parameters through.
def order_params
params.require(:order).permit(:address, :city, :state)
end
end
我的编辑页面：
<h1>编辑订单</h1>
<%= render 'form', order: @order %>
<%= link_to '返回', listing_orders_path %>
表单：
<%= form_for(model: [@listing, order], local: true) do |form| %>
<% if order.errors.any? %>
<div id="error_explanation">

<ul>
<% order.errors.full_messages.each do |message| %>

I keep getting this error when i want to enter the edit page "NO ROUTE MATCHES" ,but the weird thing is that when i change the **order = @order to @order.listing** it goes fine but there is no info to be edited, and i been scratching my head with this error for a while.
**This is my Orders Controller:**
```ruby
class OrdersController < ApplicationController

@orders = Order.all
end
# GET /orders/1
# GET /orders/1.json
def show
end
# GET /orders/new
def new
@order = Order.new
@listing = Listing.find(params[:listing_id])
end
# GET /orders/1/edit
def edit
end
# POST /orders
# POST /orders.json
def create
@order = Order.new(order_params)
@listing = Listing.find(params[:listing_id])
@seller = @listing.user
@order.listing_id = @listing.id
@order.buyer_id = current_user.id
@order.seller_id = @seller.id
respond_to do |format|

format.json { render json: @order.errors, status: :unprocessable_entity }
end
end
end

你已将 orders 设置为 listings 下的嵌套资源：
resources :listings do
resources :orders
end
这意味着 - 正如从你的路由输出中可以看出的那样 - 编辑订单的 URL 路径为：
/listings/:listing_id/orders/:id/edit
我认为你没有包含链接到编辑页面的代码，但我猜你可能在使用 Rails 生成的 URL 辅助方法，edit_listing_order_path，它需要两个参数：listing_id 和订单 ID。如果你检查那个链接，我的猜测是你没有同时指定这两个 ID。我之所以这么说，是因为如果你看一下编辑页面上的 link_to：
<%= link_to 'Atras', listing_orders_path %>
它缺少了适当的 listing 记录的 ID：
<%= link_to 'Atras', listing_orders_path(@listing) %>
我怀疑你需要检查所有的订单路径，以确保你也在指定父级 listing。
你可能还需要在你的 OrdersController 中加载 listing 实例：
def set_order
@order = Order.find(params[:id])
@listing = @order.listing # 或者从参数中获取：Listing.find(params([:listing_id])
end
英文:
You have orders set up as a nested resource under listings:
resources :listings do
resources :orders
end
That means -- as you can see from your routes output -- that the URL path for editing an order is:
/listings/:listing_id/orders/:id/edit
I don't think you included the code for the link to the edit page, but my guess is you are using the Rails-generated URL helper, edit_listing_order_path, which takes two parameters: a listing_id and an order ID. If you check that link my guess is you aren't specifying both IDs. The reason I say that is that if you look at the link_to on the edit page:
<%= link_to 'Atras', listing_orders_path %>
It is missing the ID of the appropriate listing record:
<%= link_to 'Atras', listing_orders_path(@listing) %>
I suspect you need to check all the orders paths to ensure you are also specifying the parent listing.
The other thing you likely need to do is load the listing instance in your OrdersController:
def set_order
@order = Order.find(params[:id])
@listing = @order.listing # or from parameters: Listing.find(params([:listing_id])
end
