我是软件开发人员的新手，请耐心等待。 我正在尝试从html代码接收请求，并获取shift代码值，该值可以是Shift1，Shift2或Shift3。
我正在使用只读的oracle db，这就是为什么我使用原始查询的原因。 基本上，我想通过html代码过滤表格结果，通过根据用户选择的“ Shift”结果，现在我将显示所有班次结果，如何对其进行过滤？
请在我的views.py和models.py上告诉我如何做
HTML代码：
<div id="page-content-wrapper">
<div class="container-fluid">
<a href="#menu-toggle" class="btn btn-secondary" id="menu-toggle"><< Menu</a>
<h4 align="right" >{{ date|date:'Y-m-d H:i' }} </h4>
<h1>SMD/PBA System Management</h1>
<div class="container-fluid">
Select the shift
<form action="{ %url 'show_list' %}" method="post">
<div class="form-row align-items-center">
<div class="col-auto my-1">
<select class="custom-select mr-sm-2" id="inlineFormCustomSelect" name="shift">
<option selected>Shift 1</option>
<option value="1">Shift 1</option>
<option value="2">Shift 2</option>
<option value="3">Shift 3</option>
<option value="ALL">ALL</option>
</select>
</div>
<button type="submit" value="Submit" class="btn btn-info">Search</button>
</div>
</form>

据我了解，您想从表单中返回用户检查的值；为此，您需要使用Django Forms。有关更多详细信息，请阅读文档：
