django 自带了一个分页的功能 ，使用起来很方便 。下面是使用方法 ：
views.py
def index(request):
context = {}
article = Article.objects.all()
page = request.GET.get('page',1)
context = get_paginator(article,page)
return render(request, 'home/index.html',context)
为了让主函数不要过于复杂，将分页器的功能分离出来了。
分页的主代码 ：
from django.core.paginator import Paginator,InvalidPage,EmptyPage,PageNotAnInteger
def get_paginator(obj,page):
page_size = 10 #每页显示的数量
after_range_num = 5
before_range_num = 6
context = {}
try:
page = int(page)
if page <1 :
page = 1
except ValueError:
page = 1
paginator = Paginator(obj,page_size)
try:
obj = paginator.page(page)
except(EmptyPage,InvalidPage,PageNotAnInteger):
obj = paginator.page(1)
if page >= after_range_num:
page_range = paginator.page_range[page-after_range_num:page+before_range_num]
else:
page_range = paginator.page_range[0:int(page)+before_range_num]
context["page_objects"]=obj
context["page_range"]=page_range
return context
templates 中如下实现：
<div id="content">
<div id="mainbar">
{% for article in page_objects.object_list %}
<div class="node_article">
<h3><a href='{% url home.views.index %}'>{{article.subject}}</a></h3>
<p>{{article.content|safe|escape}}</p>
</div>
{%endfor%}
<div>
<p class="page_container">
{% if page_objects.has_previous %}
<a href="?page={{ page_objects.previous_page_number }}" title="Pre">{% trans "next page"%}</a> {% endif %}
{% for p in page_range %}
{% ifequal p page_objects.number %}
<span style="font-size:16px;" title="当前页"><b>{{p}}</b></span>
{% else %}<a href="?page={{p}}" title="第{{p}}页">{{p}}</a>{% endifequal %}
{% endfor %}
{% if page_objects.has_next %}
<a href="?page={{ page_objects.next_page_number }}" title="Next">{% trans "next page"%}</a>
{% endif %}
<b>
{%if page_objects.paginator.num_pages%} {{ page_objects.paginator.num_pages }}{% trans "page"%}{%endif%}
</b>
</p>
</div>
</div>
</div>
