我有 2 个表格，一个订单表格和一个产品表格。我希望产品表格位于订单表格下。我收到此错误：无法批量分配受保护的属性：products_attributes。
这是我的订单模型
类 Order < ActiveRecord::Base attr_accessible :comments, :due_date, :order_type, :print_color, :print_location, :title, :products
验证 :order_type, :due_date, :print_color, :title, :presence => true
验证 :title, :uniqueness => true
has_many :products
accept_nested_attributes_for :products, :allow_destroy => true
end
产品型号
类 Product < ActiveRecord::Base
attr_accessible :quantity
has_one :order
end
订单控制器：
>class OrdersController < ApplicationController
# GET /orders
# GET /orders.json
def index
@orders = Order.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @orders }
end
end
# GET /orders/1
# GET /orders/1.json
def show
@order = Order.find(params[:id])
@products = @order.products.find(:all)
respond_to do |format|
format.html # show.html.erb
format.json { render json: @order }
end
end
# GET /orders/new
# GET /orders/new.json
def new
@order = Order.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @order }
end
end
# GET /orders/1/edit
def edit
@order = Order.find(params[:id])
end
# POST /orders
# POST /orders.json
def create
@order = Order.new(params[:order])
respond_to do |format|
if @order.save
format.html { redirect_to @order, notice: 'Order was successfully created.' }
format.json { render json: @order, status: :created, location: @order }
else
format.html { render action: "new" }
format.json { render json: @order.errors, status: :unprocessable_entity }
end
end
end
# PUT /orders/1
# PUT /orders/1.json
def update
@order = Order.find(params[:id])
respond_to do |format|
if @order.update_attributes(params[:order])
format.html { redirect_to @order, notice: 'Order was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @order.errors, status: :unprocessable_entity }
end
end
end
# DELETE /orders/1
# DELETE /orders/1.json
def destroy
@order = Order.find(params[:id])
@order.destroy
respond_to do |format|
format.html { redirect_to orders_url }
format.json { head :no_content }
end
end
end
