Order_Improvement v2

Hi,Dr Ji

    Thanks for your 8 emails guidance.

    I have amended the code you mentioned.

    About the code:

> +      <% if each_order.house_fitment == nil %>
> +      <div class="col-md-4" style="padding-top: 20px; height: 130px;">
> +        <p><h2>测量申请已被删除</h2></p>

   I just want prevent the whole page collapsed when the admin_user delete the house_fitment by mistake.

Thanks again!
