Question

我有一个Python Web应用程序，它将参数从数据库发送到HTML页面当页面加载时我看不到结果。

我已在检查模式下检查网络选项卡，我可以看到值已到达页面。

页面中未显示的参数是： chaccount_id，bank_name，Company，seq_id

这是我的代码：

<form id="accounts_form" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {% load staticfiles %}
Account Number:<input  list="accountslist" id="accounts_id" name="accountsname"  value="{{ Account_id }}" >
<button id="getacc_id" type="submit" name="getacc" value="commit">Get Account Details</button>
 <img id="GETACC_loading" src="{% static "app/images/small_loading.gif" %}" hidden>
    <br />   <br />
  <br /><br />

   <datalist id="accountslist">
     <select id="accounslist" size="5">
         {% for account in  accounts  %}
         <option value="{{ account.0 }}"></option>
         {% endfor %}
         </select>
     </datalist>

   </form>


<table id="theTable" hidden>
<thead>
<tr>
      <td>Account id</td>
      <td>Bank Name</td>
      <td>Company Name</td>
      <td> Counter</td>
</tr>
</thead>
<tbody>
<tr>
  <td>{{ chaccount_id }}</td>
  <td>{{ bank_name }}</td>
  <td>{{ Company }}</td>
  <td>{{ seq_id }}</td>
</tr>

</tbody>
</table>

您应该使用渲染函数在上下文中传递数据，例如：https://docs.djangoproject.com/en/1.11/topics/http/shortcuts/#render
