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">
                <form method="post">
                    {% csrf_token %}
                    <div class="form-group">
                        <label>标题</label>
                        <input type="text" class="form-control" placeholder="标题" name="title">
                    </div>

                         <button type="submit" class="btn btn-primary">提 交</button>
                </form>
            </div>
        </div>
    </div>
{% endblock %}

                <h3 class="panel-title">修改部门</h3>
            </div>
            <div class="panel-body">
                <form method="post">
                    {% csrf_token %}

                     <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>
