如何从django中的表中获取数据

Question

我正在从视图文件发送字典到django模板。在Django模板中我使用字典值创建一个表。我的要求是在表下面有一个“下载”按钮，这样当我点击按钮表时应该在excel表中下载？怎么做到这一点？

模板：

{% for set_name,set_value in pass_test_results.items %}
    <table id="final_result">
        <tr id="top-grad">
            <td colspan='4'> Ip-Address : {{set_value.ip_address}}</td>
            <td> ScanTime : {{set_value.scan_time}}</td>
        </tr>

        <tr id="table-second-top-grad">
            <th>Operating system</th>
            <th>Software</th>
            <th>Bulletin number</th>
            <th>MainKb</th>
            <th>SubKB</th>
        </tr>

        {% if set_value.missing_updates %}
            {% for category, cat_value in set_value.missing_updates.items %}
                {% if cat_value %}
                    <tr>
                        <td colspan='5' style='background-color:#81A594;'> category : {{ category }} </td>
                    </tr>
                    {% for software, soft_value in cat_value.items %}
                        {% if soft_value %}
                            {% for main_kb, kb_info in soft_value.items%}
                                {% if kb_info %}
                                    <tr>
                                        {% if category == 'OS' %}
                                            <td>{{ software }}</td>
                                        {% else %}
                                            <td>{{ kb_info.os }}</td>
                                        {% endif %}
                                        <td>{{ software }}</td>
                                        <td>{{ kb_info.b_no }}</td>
                                        <td>{{ main_kb }}</td>
                                        <td>{{ kb_info.sub_kb_list|unordered_list }}</td>
                                    </tr>
                                {% endif %}
                            {% endfor %}
                        {% endif %}
                    {% endfor %}
                {% endif %}
            {% endfor %}
            <tr>
                <td colspan='5' style='background-color:#D74B4B;'>Error Messsage : </td>
            </tr>
        {% endif %}
    </table>
    </br>
    <input class="download_button" value="Download" type="submit" name="table_download"/>
    <input class="save_to_repo_button" value="Save In Database" type="submit" name="table_save_to_repo"/>
