根據情況設定，例如這鳥樣的生成訂單，或是直接跳轉付款頁面：

detail頁面

  <form action="{% url 'orders:place' %}" method="post">
        {% csrf_token %}
            ...........
                <input type="submit" class="buy_btn" id="buy_btn" value="立即購買">
                <a href="javascript:;" class="add_cart" id
 
="add_cart" sku_id="{{ sku.id }}">加入購物車</a>
    
        </form>

cart頁面

<form action="{% url 'orders:place' %}" method="post">
        {% csrf_token %}
        ...........
        <li class="col04"><input  type="submit" id="commit_btn" value="生成訂單"></li>
    </
 
form>

獲取訂單商品

　　實現：是否登入 ----- 驗證商品來源 detail or cart ！ ------- 郵寄地址
