模板的继承
新建layout.html：
{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" href="{% static 'plugins/bootstrap-3.4.1/css/bootstrap.min.css' %}">
<style>
.navbar{
border-radius: 0;
}
</style>
</head>
<body>
<nav class="navbar navbar-default">
<div class="container">
<div class="nav-header">
<button type="button" class="navbar-toggle collapse" data-toggle="collapse"
data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar">Toggle navigation</span>
<span class="icon-bar">Toggle navigation</span>
<span class="icon-bar">Toggle navigation</span>
</button>
<a class="navbar-brand" href="#">联通用户管理系统</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li><a href="/list">部门管理</a></li>
<li><a href="#">Link</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="#">登录</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true"
aria-expanded="false">shanshan<span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#">个人资料</a></li>
<li><a href="#">我的信息</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">注销</a></li>
</ul>
</li>
</ul>
</div>
</div>
</nav>
<div>
{% block content %}{% endblock %}
</div>
<srcipt src="{% static 'js/jquery-3.6.0.min.js' %}"></srcipt>
<script src="{% static 'plugins/bootstrap-3.4.1/js/bootstrap.min.js' %}"></script>
</body>
</html>
index.html
简单的demo，用来测试模板继承
{% extends 'layout.html' %}
{% block content %}
<h1>首页</h1>
{% endblock %}depart_list.html：
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div style="margin-bottom: 10px">
<a class="btn btn-success" href="/depart/add/">
<span class="glyphicon glyphicon-plus-sign" aria-hidden="true"></span>
新建部门
</a>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<span class="glyphicon glyphicon-th-list" aria-hidden="true"></span>
部门列表
</div>
<table class="table table-bordered">
<thead>
<tr>
<th>ID</th>
<th>名称</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{% for obj in queryset %}
<tr>
<th>{{ obj.id }}</th>
<td>{{ obj.title }}</td>
<td>
<a class="btn btn-primary btn-xs" href="/depart/{{ obj.id }}/edit/">编辑</a>
<a class="btn btn-danger btn-xs" href="/depart/delete/?nid={{ obj.id }}">删除</a>
</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
</div>
{% endblock %}depart_add.html：
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">新建部门</h3>

<div class="panel-body">

depart_edit.html：
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div class="panel panel-default">

</div>
<button type="submit" class="btn btn-primary">提 交</button>
</form>
</div>
</div>
</div>
{% endblock %}用户列表：
增加urls.py
path("user/list/", views.user_list),增加views.py（get_字段_display()）
def user_list(request):
queryset = models.UserInfo.objects.all()
'''
使用python语法直接获取想要的数据
for obj in queryset:
print(obj.name, obj.create_time.strftime("%Y-%m-%d-%H-%M"), obj.get_gender_display(), obj.depart.title)
'''
return render(request, "user_list.html", {"queryset": queryset})关于获得实际的性别字段：
Django自动封装了一个方法，get_字段_display()，会根据我们在models.py里自定义的元组，
一般形式为(数据库的值，实际想显示的值)。显示数据库的值实际映射的中文。
关于获得关联的表的实际部门名称：
当然可以自己写映射，譬如
temp = models.Department.objects.filter(id=obj.depart_id).first().title
但是Django自动封装了类似一个方法，只要我们在models.py里写了
depart = models.ForeignKey(to="Department", to_field="id", on_delete=models.CASCADE)
那么他会根据id自动去关联的表中获取那一行数据的depart对象
新建user_list.html（模板语法中的日期格式化）
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div style="margin-bottom: 10px">
<a class="btn btn-success" href="#">
<span class="glyphicon glyphicon-plus-sign" aria-hidden="true"></span>
新建用户
</a>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<span class="glyphicon glyphicon-th-list" aria-hidden="true"></span>
用户列表
</div>
<table class="table table-bordered">
<thead>
<tr>
<th>ID</th>
<th>姓名</th>
<th>密码</th>
<th>年龄</th>
<th>余额</th>
<th>入职时间</th>
<th>性别</th>
<th>所属部门</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{% for obj in queryset %}
<tr>
<th>{{ obj.id }}</th>
<td>{{ obj.name }}</td>
<td>{{ obj.password }}</td>
<td>{{ obj.age }}</td>
<td>{{ obj.account }}</td>
<td>{{ obj.create_time|date:"Y-m-d" }}</td>

<a class="btn btn-primary btn-xs" href="#">编辑</a>

{% endfor %}

</table>
