Question

我正在开发一个订单管理系统，用户可以在其中向客户添加订单。到目前为止，我可以添加客户，编辑现有订单和删除现有客户。我可以通过ruby控制台向客户添加订单，但不能通过网络添加订单。我希望有人可以帮助我。

这是我得到Webversion的错误消息

我的订单控制器

class OrdersController < ApplicationController
  def index
     @order = Order.find(params[:customer_id])
  end

  def new
      @customer = Customer.find params[:customer_id]
      @order = @customer.orders.new
   end


    def create
      @customer = Customer.find(params[:customer_id])
      @order = @customer.orders.new(params[:order]) 
      @order.save
   end

  end

  def show
   @order = Order.find(params[:customer_id]) 
  end

  def edit
     @customer = Customer.find(params[:customer_id])
  end

    def update
    #Find a exisiting object using form paramters
     @order = Order.find(params[:id])
    if @order.update_attributes(order_params)

    #if Update succeeds, redirect to the index action
    flash[:notice] = "Subject updated successfully"
    redirect_to(:action => 'show', :id => @order.id)
    else
    #If save fails, redisplay the form so user can fix problems
    render('edit') #het zit in de new.html template
    end
  end

  def delete
  end

  private
  def order_params
    params.require(:order).permit(:customer_id, :pakket, :verstuurt)
  end

我的订单

<%= form_for @order do |f| %>   <table summary="subject form fields">
    <%= f.hidden_field :customer_id , :value=>params[:customer_id] %>
    <tr>
      <th>Package</th>
      <td><%= f.text_field(:order) %></td>
    </tr>
    <tr>
    <th>Sent</th>
      <td><%= f.text_field(:verstuurt) %></td>
    </tr>   </table>

  <div class="form-buttons">
    <%= f.submit "create" %>    </div> <% end %>

我的路由

Rails.application.routes.draw do

  resources :orders do
  resources :customers
  end


  get ':controller/:action/:id/:customer_id'
  get ':controller/:action/:id/:customer_id'


  get 'customers/index'

  get 'customers/new'

  get 'customers/show'

  get 'customers/edit'

  get 'customers/delete'

  match ':controller(/:action(/:id))', :via => [:get, :post]

  get 'orders/index'

  get 'orders/new'


  get 'orders/show'

  get 'orders/edit'

  get 'orders/delete'

Answer 1

尝试从

更改隐藏字段

<%= f.hidden_field :customer_id , :value=>params[:customer_id] %>

到

<%= f.hidden_field :customer_id , :value=> @order.customer_id %>

我无法向客户添加订单
