我想从这个 JSON 列表数据中按 id 过滤它并在 html 模板上显示它！基本上这需要编辑任务。当有人点击编辑按钮时，特定的 id 被传递。 like.. 当 id 为 147 时，我想打印 147 的其他数据，如姓名、描述、余额、帐户详细信息类型！这就像一个单独的对象。

查看以下 HTML 格式：这里我想在值 {{}} 模板中显示名称、描述、余额等数据：

                                 <div class="form-group row">
                                    <label class="col-form-label col-md-2">Name</label>
                                    <div class="col-md-10">
                                        <input type="text" class="form-control" name="name"
                                               value="{{ }}">
                                    </div>
                                </div>
                               <div class="form-group row">
                                    <label class="col-form-label col-md-2">Description</label>
                                    <div class="col-md-10">
                                        <input type="text" class="form-control" name="desc"
                                               value="{{ }}">
                                    </div>
                                </div>
                              <div class="form-group row">
                                    <label class="col-form-label col-md-2">Balance</label>
                                    <div class="col-md-10">
                                        <input type="text" class="form-control" name="bal"
                                               value="{{ }}">
                                    </div>
                                </div>

【问题讨论】：

  • 您可以为此使用 javascript，例如编辑按钮上的 onClick 事件

标签： python django oop web rest


【解决方案1】：

最好将此json文件作为模型存储在项目中，并在发送所需的Id时渲染html。 例如，如果 givenId = 147 被按下。 view.py 中的函数可以在哪里运行

chart = chartsOfAccounts.object.filter(id=givenId)
return render(request,<htmlfile>,{"chart":chart})

在html中你可以使用图表模型来获取以下数据。

{{ 图表名称 }} {{ chart.desc }}

否则将json文件转换为字典并发送值

【讨论】：

  • AttributeError at 'list' object has no attribute 'objects'
  • 您需要在model.py中创建模型，将数据存储在数据库中，然后将数据作为对象检索。它不应该是列表类型
  • 我知道……伙计！其实问题是..没有模型！我正在通过 request.post() 方法从 API 获取 JSON 数据。但最后我用自己的努力解决了这个问题！感谢您提出一些可能的解决方案！
