Django-bootstrap3
Bootstrap来自Twitter的前端框架，基于HTML、CSS、JavaScript，简洁灵活，使得Web开发更快捷，而Django-bootstrap3是将Bootstrap3集成到了Django中，作为Django的一个应用，从而快速的创建Web前端页面
安装django-bootstrap3
E:\Programs\Python\Python_Django_Interface>pip install django-bootstrap3

然后修改…/guest/settings.py文件，添加bootstrap3应用
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'sign',
'bootstrap3',
]
修改…/sign/views.py中的event_manage()视图函数
@login_required
def event_manage(request):
#username = request.COOKIES.get('user', '') # 读取浏览器 cookie
username = request.session.get('user', '') # 读取浏览器 session
events = Event.objects.all() # 查询所有发布会数据
return render(request, "event_manage.html", {"user": username, "events": events}) # 通过render附加在event_manage.html页面返回给客户端
修改…/templates/event_manage.html页面文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Guest Manage</title>
<!--加载bootstrap3应用、CSS、JavaScript文件， {% %}是Django模板语言的标签 -->
{% load bootstrap3 %}
{% bootstrap_css %}
{% bootstrap_javascript %}
</head>
<body role="document">
<!-- 导航栏 -->
<nav class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<a class="navbar-brand" href="/event_manage/">Guest Manage System</a>
</div>
<div id="navbar" class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<!--设置导航栏，class="active" 表示当前菜单处于选中状态 -->
<li class="active"><a href="#">发布会</a></li>
<li><a href="/guest_manage/">嘉宾</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<!--{{ }}为Django的模板语言标签，用于定义显示变量，user为客户端获取的浏览器sessionid对应的登录名 -->
<li><a href="#">{{user}}</a></li>
<li><a href="/logout/">退出</a></li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>
<!--发布会表单-->
<div class="row" style="padding-top: 80px">
<div class="col-md-6" style="width: 900px;">
<table class="table table-striped">
<thead>
<tr>
<th>id</th>
<th>名称</th>
<th>地址</th>
<th>时间</th>
<th>人数</th>
<th>状态</th>
<th>签到</th>
<!-- <th>签到正式</th> -->
</tr>
</thead>
<tbody>
<!--通过Django模板语言，循环打印发布的id，name，status，address和start_time等字段-->
<!--Django模板语言与Python语言并非完全一样，for循环语句需要有对应的endfor来表示语句的结束-->
<!--同样的，if语句也需要endif来结束-->
{% for event in events %}
<tr>
<td>{{ event.id }}</td>
<td>{{ event.name }}</td>
<td>{{ event.address }}</td>
<td>{{ event.start_time | date:"Y-m-d H:i:s" }}</td>
<td>{{ event.limit }}</td>
<td>{{ event.status }}</td>
<td><a href="/sign_index/{{ event.id }}/" target="{{ event.id }}_blank">sign</a></td>
<!-- <td><a href="/sign_index2/{{ event.id }}/" target="{{ event.id }}_blank">sign_web</a></td>
-->
</tr>
{% endfor %}
{{ hint }}
</tbody>
</table>
</div>
</div>
</body>
</html>
重新登陆系统，到http://127.0.0.1:8000/event_manage/页面，如图显示：
继续修改…/templates/event_manage.html文件中添加搜索菜单
<!--查询发布会-->
<div class="page-header" style="padding-top: 60px;">
<div id="navbar" class="navbar-collapse collapse">
<form class="navbar-form" method="get" action="/search_name/">
<div class="form-group">
<input name="name" type="text" placeholder="名称" class="form-control">
</div>
<button type="submit" class="btn btn-success">搜索</button>
</form>
</div><!--/.navbar-collapse -->
<div>
<button type="submit" class="btn btn-primary" onclick="window.location.href='/add_event/'" style="margin-top: 8px;">添加</button>
</div>
</div>
刷新页面如下所示：
为搜索添加路由，需改…/guest/urls.py文件
from django.contrib import admin
from django.urls import path
from sign import views
from django.conf.urls import url
urlpatterns = [
path(r'admin/', admin.site.urls),
path(r'index/', views.index), # 添加index/路径配置
url(r'login_action/', views.login_action),
url(r'event_manage/', views.event_manage),
url(r'^$', views.index),
url(r'^index/$', views.index),
url(r'^accounts/login/$', views.index),
url(r'^search_name/$', views.search_name),
]
添加search_name()函数，修改…/sign/views.py文件
# 发布会名称搜索
@login_required
def search_name(request):
username = request.session.get('user', '')
search_name = request.GET.get("name", "")
#search_name_bytes = search_name.encode(encoding="utf-8")
events = Event.objects.filter(name__contains=search_name)
if len(events) == 0:
return render(request, "event_manage.html", {"user": username,
"hint": "根据输入的 `发布会名称` 查询结果为空！"})
return render(request, "event_manage.html", {"user": username, "events": events})
然后试一下搜索功能吧，比如搜索“发布会A”
