Question

我有一个django模板，显示数据库中的项目列表。我打算在点击时编辑或更新每个项目。我已经能够打印我想要更新的项目，但我有一个问题。我们遇到的问题是这些项目不会以模态形式填充。

这是代码。

{% block body_block %}
{% if items %}
                    {% for product in items %}
                    <tr align="center">
                        <td>{{product.docfile}}</td>
                        <td>{{product.description}}</td>
                        <td >{{product.price}}</td>
                        <td >{{product.quantity}}</td>
                        <td>
                            <a href="#{{product.pk}}" class="manipulate btn btn-info btn-lg" item_id="{{product.pk}}">Update</a>
                        </td>
                    </tr>
                    <input type="hidden" id="ds" value="{{product.description}}">
                    {% endfor %}
                {% else %}
                    <p>You have <strong>no items</strong> currently in your cart! <strong>Add items now!</strong>
                    </p>
                {% endif %}
            </table>
            <br><br><br>

        <!-- Modal -->
        <div class="modal fade" id="edititemModal{{product.pk}}" role="dialog" style="height: auto;">
            <div class="modal-dialog">
            <!-- Modal content-->

                    <div class="modal-body">

        });
    </script>
    {% endblock %}

请问我在jquery结束时做得不对？

在您的视图中，无论您在何处创建表单对象，都要添加初始参数。这是文档链接 - https://docs.djangoproject.com/en/1.9/ref/forms/api/#dynamic-initial-values
