python - Bootstrap 模态不更新模态内容

Question

我正在尝试创建一个模型表，模型旁边有一个按钮，该按钮打开一个模式并在表单 View 中具有相同的模型行。该表已正确填充，但正在创建的 n 个 bootstrap modals 仅包含第一个可迭代模型值。是因为 Bootstrap 在呈现页面时仅加载模态内容一次吗？我该怎么做才能解决这个问题？我是否应该运行一个函数来根据它具有的模型数据更新模态内容？？

如有任何疑问，请随时提出。

{% extends 'base.html' %}

{% load static %}

{% block content %}

        {% for item in data %}

                <th>Material Type</th>

Answer 1

您可以通过将 model.pk 添加到模态 id 来修复它

在按钮中

<button type="button" class="btn btn-primary btn-lg" data-toggle="modal"
     data-target="#myModal{{ item.id }}">
    Bid now! for id {{ item.id }}
</button>

在

 <div class="modal fade"
      id="myModal{{ item.id }}"
      tabindex="-1" role="dialog" aria-labelledby="myModalLabel">

其他解决方案是创建 js 函数以在每次激活模式时加载新数据。
