<h2>order⇄ordered_item(中間) ⇄ item　モデル設定する</h2>
<p>order　⇄　ordered_item ⇄ item</p>
<p>多：多になるので中間テーブルを介してデータやりとりする</p>
```ruby:model/order.rb

enum payment_method: ["クレジットカード", "銀行振込"]
end

```ruby:model/item.rb class Item < ApplicationRecord has_many :ordered_items #中間テーブル has_many :orders, through: :ordered_items : ```

ordered_item.rb 中間テーブル

```model/ordered_item.rb class OrderedItem < ApplicationRecord belongs_to :order belongs_to :item ```

コントローラー

```ruby:orders.controller class Member::OrdersController < ApplicationController before_action :authenticate_member! def new # 注文情報入力画面 = Order.new = current_member.addresses.all end ： ```

住所を(0)[自分の住所](1)[アドレス張](2)[新規]から選択する

注文情報入力画面　new.htmlで条件分けてformを送り、

def confirmでデータを設定し直す

データを入力し送る→データを保存せずにそのまま表示→次の画面でデータ保存の流れ

(0)まずは[自分の住所]の時

```html:orders/new.html.erb

注文情報入力

<%= form_with model: , url: "/orders/confirm", method: :post, local: true do |f| %> :

お届け先

　　　#[:address_option]=="0"として設定する <%= f.radio_button :address_option, 0, checked: "checked" %> #checked:予めbuttn選択される　 <%= f.label :order_address, "ご自身の住所" %>
〒<%= current_member.post_code %> #郵便番号 <%= current_member.address %>
　＃住所 <%= current_member.last_name %><%= current_member.first_name %>　#名前
: <%end%> ```

new.htmlの[:address_option]=="0データをdef confirmで移す

orders.controller.rb

class Member::OrdersController < ApplicationController
    before_action :authenticate_member!
def confirm   # 注文情報入力確認画面
        @order = Order.new(order_params)
   
    #  [:address_option]=="0"のデータ(memberの住所)を呼び出す
        if params[:order][:address_option] == "0"
        @order.shipping_post_code = current_member.post_code
        @order.shipping_address = current_member.address
        @order.shipping_name = current_member.last_name + current_member.first_name 
         :
    end
:
private
    def order_params
        params.require(:order).permit(:postage, :payment_method, :shipping_name, :shipping_address, :shipping_post_code ,:member_id,:total_payment,:status)
    end
    
end

(1)[アドレス張]から情報を表示させてデータを送る

```html:new.html.erb <%= form_with model: , url: "/orders/confirm", method: :post, local: true do |f| %> : <%= f.radio_button :address_option, 1 %> 　#[:address_option]=="1"が呼出　送る <%= f.label :order_address, "登録済住所から選択" %>
<%= f.collection_select :member_id, , :id, :full_adresses %> 　　　　#第一引数メソッド名　:member_id　にひもづく　adresses : #コントローラの　 = current_member.addresses.all : #　:id, :full_adresses　カラムとってくる : <%end%> ```

new.htmlの[:address_option]=="1" データをdef confirmで移す

```ruby:orders.controller.rb def confirm # 注文情報入力確認画面 = Order.new(order_params) : # [:address_option]=="1"を呼び出す elsif params[:order][:address_option] == "1" ship = Address.find(params[:order][:member_id]) 　　　　　　　#orderのmember_id(=カラム)でアドレス(帳)を選び、そのデータ送る @order.shipping_post_code = ship.post_code @order.shipping_address = ship.address @order.shipping_name = ship.name ```

(2)[新規]で住所入力　text_fieldに入れてもらう

```html:new.html.erb <%= form_with model: , url: "/orders/confirm", method: :post, local: true do |f| %> : 　#[:address_option]=="2"として,text_field に入れたデータを送る <%= f.radio_button :address_option, 2 %> <%= f.label :order_address, "新しいお届け先" %> 　

<%= f.label :shipping_post_code, "郵便番号(ハイフンなし)" %>	<%= f.text_field :shipping_post_code　%>
<%= f.label :shipping_address, "住所" %>	<%= f.text_field :shipping_address %>
<%= f.label :shipping_name, "宛名" %>	<%= f.text_field :shipping_name %>

<%= f.submit "確認画面へ進む" %> <% end %> ```

new.htmlの[:address_option]=="2" text_fieldデータをdef confirmで移す

orders.controller.rb

 def confirm   # 注文情報入力確認画面
    @order = Order.new(order_params)
      :    
 　　# 新規住所入力 [:address_option]=="2"としてデータをhtmlから受ける
　　 elsif params[:order][:address_option] = "2"
        @order.shipping_post_code = params[:order][:shipping_post_code]
        @order.shipping_address = params[:order][:shipping_address]
        @order.shipping_name = params[:order][:shipping_name]
        else
            render 'new'
        end
      :

注文情報入力画面に　支払い方法もかく

new.html.erbでは支払い方法も入力するので追記

```html:order/new.html.erb

注文情報入力

<%= form_with model: , url: "/orders/confirm", method: :post, local: true do |f| %>

支払い方法

<%= f.radio_button :payment_method,:クレジットカード,checked: "checked" %> <%= f.label :payment_method, "クレジットカード" %>
<%= f.radio_button :payment_method, :銀行振込 %> <%= f.label :payment_method, "銀行振込" %>

お届け先

: <%= f.radio_button :address_option, 0, checked: "checked" %> :（以下：上に記載したもの）　　: <%end%> ```

注文確認 orders/confirm.html.erb

orders_controller.rb

def confirm
    @order = Order.new(order_params)
  :
  :  #params[:order][:address_option] == "0"から"2"の 住所データを定義する
　:   @order.shipping_post_code = 
  :   @order.shipping_address = 
  :   @order.shipping_name =   
  :         :
  :
    @cart_items = current_member.cart_items.all
 end

分岐で定義したおかげで、お届け先が表示できる

```html:confirm.html.erb

注文情報確認

支払い方法 <%= @order.payment_method %> お届け先 <%= @order.shipping_post_code %> #郵便番号 <%= @order.shipping_address %>　 #住所 <%= @order.shipping_name %> #名前 ```

カート商品をconfirm注文確認画面で表示させる

```ruby:OrdersController class Member::OrdersController < ApplicationController before_action :authenticate_member! # 注文情報入力確認画面 def confirm = Order.new(order_params) : (上記記載) 　　　　　: = current_member.cart_items.all end ``` ```html:confirm.html.erb

注文情報確認

<% total = 0 %> #合計金額total初期化 <% @cart_items.each do |cart_item| %> <% total += (cart_item.item.price*cart_item.quantity)*1.08 %> #アイテムごとに合計金額に加算 <% end %>

商品名	単価(税込)	数量	小計
<%= attachment_image_tag(cart_item.item, :image, size: "60x50", fallback: "no_image.jpg") %> <%= cart_item.item.name %>	<%= (cart_item.item.price*1.08).to_i %>	<%= cart_item.quantity %>	<% subtotal = ((cart_item.item.pricecart_item.quantity)1.08).to_i %> <%= subtotal %>#小計を表示

<% @order.postage = 800 %> <% @order.total_payment = @order.postage + total.to_i %>

送料	<%= @order.postage %>
商品合計	<%= total.to_i %>
請求金額	<%= @order.total_payment %>

: ```

注文確認画面でorderを保存

```ruby:OrdersController class Member::OrdersController < ApplicationController before_action :authenticate_member! : def create = Order.new(order_params) @order.save : end : private def order_params params.require(:order).permit(:postage, :payment_method, :shipping_name, :shipping_address, :shipping_post_code ,:member_id,:total_payment,:status) end end


```html:orders/confirm.html.erb
   :      
<%= form_with model: @order, url: orders_path, method: :post, local: true do |f| %>
   <%= f.hidden_field :member_id %>
   <%= f.hidden_field :postage %>
   <%= f.hidden_field :total_payment %>
   <%= f.hidden_field :payment_method %>
   <%= f.hidden_field :shipping_name %>
   <%= f.hidden_field :shipping_address %>
   <%= f.hidden_field :shipping_post_code %>
   <%= f.hidden_field :status %>
  <%= f.submit "注文を確定する", class: "btn btn-success" %>
 <% end %>

カートは空にするのでordered_itemに保存しておく

```ruby: def create = Order.new(order_params) @order.member_id = current_member.id @order.save

ordered_itmemに保存

current_member.cart_items.each do |cart_item| #カート内商品を1つずつ取り出しループ

　　　@ordered_item = OrderedItem.new #初期化宣言
　　 @ordered_item.order_id = @order.id #order注文idを紐付けておく
@ordered_item.item_id = cart_item.item_id #カート内商品idを注文商品idに代入
@ordered_item.quantity = cart_item.quantity #カート内商品の個数を注文商品の個数に代入
@ordered_item.tax_included_price = (cart_item.item.price*1.08).floor #消費税込みに計算して代入
@ordered_item.save #注文商品を保存
end #ループ終わり

    current_member.cart_items.destroy_all #カートの中身を削除
    redirect_to thanx_orders_path
