python - 如何以表格形式显示值，因为现在只显示表格标题

Question

Timesheet.html 基本上是一个用于填写详细信息的表单。我创建了一个 list_timesheet.html 来列出所有正在填写的时间表。但是我不知道我什么时候运行它只显示这样的标题:{ % for item in query_results % } { % end for % }学生证学生姓名开始日期结束日期

list_timesheet.html

<form method="POST" class="display"  cellspacing="0" width="100%">
    {% csrf_token %}
    <table>
        <tr>
            <th> Student ID </th>
            <th> Student Name </th>
            <th> Start Date </th>
            <th> End Date </th>
        </tr>
        { % for item in query_results % }
        <tr>
            <td>{{item.studentID}}</td>
            <td>{{item.studentName}}</td>
            <td>{{item.startDate}}</td>
            <td>{{item.endDate}}</td>
        </tr>
        { % end for % }
    </table>
</form> 

timesheet.html

<form method="POST" onsubmit="return validation()">
    {% csrf_token %}

改变你的看法

在 view.py 中查询后在您的模板中

{% for item in query_results %} 
<tr> 
<td>{{item.studentName }}</td> 
<td>{{item.put_field_you_have_in_model }}</td> 
</tr> 
{% endfor %} 

并在 list_timesheet.html 中

   {% for item in query_results %}
    <tr>
        <td>{{item.studentID}}</td>
        <td>{{item.studentName}}</td>
        <td>{{item.startDate}}</td>
        <td>{{item.endDate}}</td>
    </tr>
    {% endfor %}
