#下一步是告诉Django在哪里可以找到静态文件。打开settings.py，拉到文件的底部，在STATIC_URL后面添加以下内容：
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static'),
]
<!--现在我们必须在模板中加载静态文件（Bootstrap CSS文件）：-->
<!--只要记住但凡是引用到CSS,JavaScript或图片文件的地方就是要{% load static %}.-->
<!--templates/home.html-->
{% load static %}<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Boards</title>
<link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}">
</head>
<body>
<h1>Boards</h1>
<table border="1">
<thead>
<tr>
<th>Board</th>
<th>Posts</th>
<th>Topics</th>
<th>Last Post</th>
</tr>
</thead>
<tbody>
{% for board in boards %}
<tr>
<td>{{ board.name }}<br>
<small style="color: #888">{{ board.description }}</small>
</td>
<td>0</td>
<td>0</td>
<td></td>
</tr>
{% endfor %}
</tbody>
</table>
</body>
</html>
<!--现在我们可以编辑模板，以利用Bootstrap CSS：-->
{% load static %}<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Boards</title>
<link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}">
</head>
<body>
<div class="container">
<ol class="breadcrumb my-4">
<li class="breadcrumb-item active">Boards</li>
</ol>
<table class="table">
<thead class="thead-inverse">
<tr>
<th>Board</th>
<th>Posts</th>
<th>Topics</th>
<th>Last Post</th>
</tr>
</thead>
<tbody>
{% for board in boards %}
<tr>
<td>{{ board.name }}
<small class="text-muted d-block">{{ board.description }}</small>
</td>
<td class="align-middle">0</td>
<td class="align-middle">0</td>
<td></td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
</body>
</html>
