嘗試保存到Rails中的父表和子表，但在嵌套的屬性上獲取參數錯誤

Question

您好我想從一個表單同時保存到兩個表。 我已創建Contact與has_many的關係Order其中belongs_toContact。

型號/ contact.rb

class Contact < ActiveRecord::Base 
    has_many :orders 
    accepts_nested_attributes_for :orders, reject_if: :all_blank 
end 

型號/ order.rb

class Order < ActiveRecord::Base 
    belongs_to :contact 
end 

我也創建看起來如下

控制器/ OrdersController.rb

的OrdersController

class OrdersController < ApplicationController 
    def new  
     @contact = Contact.new 
     @contact.orders.build 
    end 

    def create 
     @contact = Contact.new(order_params) 
     if @contact.save 
      @order = @contact.orders.build(order_params) 
      @order.save 
      flash[:success] = "Your has been sent we'll get back to you shortly" 
      redirect_to new_order_path 
     else 
      flash[:danger] = "We were unable to process your request please try again or email admin@careerfalir.co.za" 
      redirect_to new_order_path 
     end 
    end 

    . . . 
    private 
     def order_params 
      params.require(:contact).permit(:id,:name,:surname, :email, :comments, :dob, :phone_number, :contact_method, orders_attributes: [:email, :contact_id,:package,:jobs_strategy,:fast_turn_around,:order_comments, :contact_email]) 
     end 
end 

當我嘗試和創造，我得到一個錯誤未知屬性的順序：命名

@contact = Contact.new(order_params) 
    if @contact.save 
     *** @order = @contact.orders.build(order_params) *** This is the line with the error 
     @ordar.save 
     flash[:success] = "Your has been sent we'll get back to you shortly" 
     redirect_to new_order_path 

名稱不Orders表上存在，爲什麼我認爲它是抱怨，但它確實在聯繫人表中。我應該創造這種不同？

我也試過@order = @contact.orders.create(order_params)與同樣的錯誤。

這裏是視圖

<%= form_for @contact, url: orders_path do |f| %> 

     <div> 
      <%= f.label :name %> 
      <%= f.text_field :name, class:"form-control" %> 
     </div> 
     <div> 
..... 
    <%= f.fields_for :order do |order| %> 
     <div> 
      <%= order.label :package %> 
      <%= order.text_field :package, class: "form-control" %> 
     </div> 

Answer 1

1）第一點是所述創建方法的@ordar.save代替@order.save其中我假定爲錯字

2）的樣品的第二點是@order = @contact.orders.build(order_params)這條線不需要order_params，應該是簡單的@order = @contact.orders.build

所以這些改變你的創建acti on應該是，

def create 
    @contact = Contact.new(order_params) 
    if @contact.save 

     flash[:success] = "Your has been sent we'll get back to you shortly" 
     redirect_to new_order_path 
    else 
     flash[:danger] = "We were unable to process your request please try again or email admin@careerfalir.co.za" 
     redirect_to new_order_path 
    end 
end
