Django中实现分页

1、view重写Paginator类

from django.core.paginator import Paginatorclass JuncheePaginator(Paginator):    def __init__(self, object_list, per_page, range_num=5, orphans=0, allow_empty_first_page=True):        Paginator.__init__(self, object_list, per_page, orphans, allow_empty_first_page)        self.range_num = range_num    def page(self, number):        self.page_num = number        return super(JuncheePaginator, self).page(number)    def _page_range_ext(self):        #print type(self.page_num)         #！！！坑        #type(self.page_num)==unicode导致self.page_num - i没有结果，循环直接结束        self.page_num= int(self.page_num)         num_count = 2 * self.range_num + 1        if self.num_pages <= num_count:            return range(1, self.num_pages + 1)        num_list = []        num_list.append(self.page_num)        for i in range(1, self.range_num + 1):            if self.page_num - i <= 0:                num_list.append(num_count + self.page_num - i)            else:                num_list.append(self.page_num - i)            if self.page_num + i <= self.num_pages:                num_list.append(self.page_num + i)            else:                num_list.append(self.page_num + i - num_count)        num_list.sort()        return num_list    page_range_ext = property(_page_range_ext)

2、view分页方法

def paging(request):    article = Article.objects.all().order_by('-created_time')    paginator = JuncheePaginator(article,1) # Show 25 contacts per page    page = request.GET.get('page')    try:        article = paginator.page(page)    except PageNotAnInteger:        # If page is not an integer, deliver first page.        article = paginator.page(1)    except EmptyPage:        # If page is out of range (e.g. 9999), deliver last page of results.        article = paginator.page(paginator.num_pages)    return render(request, 'blog/paging.html', {'contacts': article})

3、分页模板

{% for contact in contacts %}    {# Each "contact" is a Contact model object. #}    {{ contact.full_name|upper }}<br />    ...     {{ contact.title}}{% endfor %}<div>    {% if contacts.has_previous %}        <a href='?page={{ contacts.previous_page_number }}'>&lt;&lt;</a>    {% endif %}    {% for page in contacts.paginator.page_range_ext %}        {% ifequal page contacts.number %}            <a>{{ page }}</a>        {% else %}            <a href='?page={{ page }}'>{{ page }}</a>        {% endifequal %}    {% endfor %}    {% if contacts.has_next %}        <a href='?page={{ contacts.next_page_number }}'>&gt;&gt;</a>    {% endif %}</div>

4、url设置

urlpatterns = [        url(r'^pag$', views.paging, name='page_list')    ]

init()函数不用说了吧，就是重载了一下，添加了一个range_num参数，代表在可能的情况下，当前页左右各显示多少个页标签，默认值为5。
page()函数是对父类Paginator的page()函数的重写，主要是为了记录当前页。
核心是_page_range_ext()函数，它实现了我们根据page_num的情况来返回恰当的页面列表，page_num取默认值的情况下，如果当前页是8，则我们返回的页数列表就应该是[3,4,5,6,7,8,9,10,11,12,13]，但如果说是当前页是2，则会返回[1,2,3,4,5,6,7,8,9,10,11]，其余的以此类推。具体算法我就不仔细分析了，大家可以参看源代码，个人感觉还可以优化，但我现在也就能用就行。
