5.1.自定义403，404和500页面
（1）website/urls.py
from blog import views as blog_views handler403 = blog_views.permission_denied
handler404 = blog_views.page_not_found
handler500 = blog_views.page_error
（2）views.py
def permission_denied(request):
''''''
return render(request, 'blog/403.html', locals()) def page_not_found(request):
''''''
return render(request, 'blog/404.html', locals()) def page_error(request):
''''''
return render(request, 'blog/500.html', locals())
还要改detail的view
（3）403，404,500页面
{% extends 'blog/base.html' %}
{% block title %}403{% endblock %}
{% block content %}
<section class="container text-center" style="min-height:600px;">
<h1>403, Forbidden!</h1>
<p>你没有权限访问该页面</p>
<a class="btn btn-primary" href="{% url 'blog:blog_index' %}">返回主页</a>
</section>
{% endblock %}
blog/403.html
{% extends 'blog/base.html' %}
{% block title %}404{% endblock %}
{% block content %}
<div class="container text-center" style="min-height:600px;">
<h1>404, Page not Found!</h1>
<h2>页面不存在!</h2>
<a class="btn btn-primary" href="{% url 'blog:blog_index' %}">返回主页</a>
</div>
{% endblock %}
404
{% extends 'blog/base.html' %}
{% block title %}500{% endblock %}
{% block content %}
<section class="container text-center" style="min-height:600px;">
<h1>500, Page Error!</h1>
<p>服务器错误！</p>
<a class="btn btn-primary" href="{% url 'blog:blog_index' %}">返回主页</a>
</section>
{% endblock %}
500
生成环境下才有效：DEBUG = False
5.2.sitemap（站点地图）
（1）settings.py
INSTALLED_APPS = [
'django.contrib.sitemaps',
]
（2）web/urls.py
from django.contrib.sitemaps import GenericSitemap
from django.contrib.sitemaps.views import sitemap
from blog.models import Entry info_dict = {
'queryset': Entry.objects.all(),
'date_field': 'modifyed_time'
} url(r'^sitemap\.xml$', sitemap, {'sitemaps': {'blog': GenericSitemap(info_dict, priority=0.6)}},
name='django.contrib.sitemaps.views.sitemap'), #站点地图
from django.conf.urls import url,include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from blog.feed import LatestEntriesFeed
from blog import views as blog_views from django.contrib.sitemaps import GenericSitemap
from django.contrib.sitemaps.views import sitemap
from blog.models import Entry info_dict = {
'queryset': Entry.objects.all(),
'date_field': 'modifyed_time'
} urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^blog/',include('blog.urls') ),
url(r'^latest/feed/$', LatestEntriesFeed()), #RSS订阅
url(r'^sitemap\.xml$', sitemap, {'sitemaps': {'blog': GenericSitemap(info_dict, priority=0.6)}},
name='django.contrib.sitemaps.views.sitemap'), #站点地图
] + static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT ) #添加图片的url handler403 = blog_views.permission_denied
handler404 = blog_views.page_not_found
handler500 = blog_views.page_error
web/urls.py
（3）访问地址：http://127.0.0.1:8000/sitemap.xml
5.3.博客详情页目录
（1）right_site_bar.html
因为只有详情页右边才显示目录，主页不显示，在right_side_bar.html添加一个block
（2）detail.html
<div class="col-md-3">
{% block toc %}
<div class="row">
<div class="widget">
<h3>博客目录</h3>
{{ entry.toc|safe }}
</div>
</div>
{% endblock %}
{% include 'blog/right_site_bar.html' %}
</div>
把之前在正文里面显示的目录删了，只要右侧显示目录就行了
5.4.返回顶部功能
（1）base.html
<div id="back-to-top">
<i class="glyphicon glyphicon-arrow-up"></i>
</div>
（2）css代码
base.html引用
<link href="{% static 'blog/css/back-to-top.css' %}" rel="stylesheet">
blog/css/back-top-css.css代码
#back-to-top {
box-shadow: 5px 5px 5px #888888;
border-radius: 2px;
position: fixed;
bottom: 70px;
right: 70px;
color: whitesmoke;

width: 50px;
height: 50px;
text-align: center;
}
#back-to-top i {
font-size: 30px;
margin: 10px auto;
}
（3）js代码
base.html
<script>
$("#back-to-top").click(function () {
window.scrollTo(0,0);
});
</script>
