Django的分页器（paginator）

总之不太好用我们还是用自己的好一些 

自定义分页器

分页实现源码

"""自定义分页组件"""class Pagination(object):    def __init__(self, current_page, all_count, base_url, params, per_page_num=8, pager_count=11, ):        """        封装分页相关数据        :param current_page: 当前页        :param all_count:    数据库中的数据总条数        :param base_url: 分页中显示的URL前缀        :param params:  request.get 对象        :param per_page_num: 每页显示的数据条数        :param pager_count:  最多显示的页码个数        """        try:            current_page = int(current_page)        except Exception as e:            current_page = 1        if current_page < 1:            current_page = 1        self.current_page = current_page        self.all_count = all_count        self.per_page_num = per_page_num        self.base_url = base_url        all_pager, tmp = divmod(all_count, per_page_num)        if tmp:            all_pager += 1        self.all_pager = all_pager        self.pager_count = pager_count        self.pager_count_half = int((pager_count - 1) / 2)        import copy        params = copy.deepcopy(params)        params._mutable = True        self.params = params  # self.params : {"page":77,"title":"python","nid":1}    @property    def start(self):        return (self.current_page - 1) * self.per_page_num    @property    def end(self):        return self.current_page * self.per_page_num    def page_html(self):        # 如果总页码 < 11个：        if self.all_pager <= self.pager_count:            pager_start = 1            pager_end = self.all_pager + 1        # 总页码  > 11        else:            # 当前页如果<=页面上最多显示(11-1)/2个页码            if self.current_page <= self.pager_count_half:                pager_start = 1                pager_end = self.pager_count + 1            # 当前页大于5            else:                # 页码翻到最后                if (self.current_page + self.pager_count_half) > self.all_pager:                    pager_start = self.all_pager - self.pager_count + 1                    pager_end = self.all_pager + 1                else:                    pager_start = self.current_page - self.pager_count_half                    pager_end = self.current_page + self.pager_count_half + 1        page_html_list = []        self.params["page"] = 1        first_page = '

视图函数调用

from django.shortcuts import render,HttpResponse# Create your views here.from .models import *def index(request):    '''    book_list=[]    for  i in range(500):        book_obj=Book(title="book_%s"%i,price=i*i)        book_list.append(book_obj)    Book.objects.bulk_create(book_list)    '''    current_page = request.GET.get("page", 1)    all_count = Book.objects.all().count()    base_url = request.path  # /index/    from app01.utils.page import Pagination    pagination = Pagination(int(current_page),all_count,base_url,request.GET, per_page_num=8, pager_count=11,)    # def __init__(self, current_page, all_count, base_url, params, per_page_num=8, pager_count=11, ):    book_list = Book.objects.all()[pagination.start:pagination.end]    from django.http.request import QueryDict    # dic = QueryDict(mutable=True)    # dic["info"] = 123    # print(type(request.GET))    # request.GET["info"]=123    import copy    params = copy.deepcopy(request.GET)    params["xxx"] = 123    return render(request, "index.html", locals())

模板使用展示

    
              
          
          
      
      
           {
     % for foo in book_list %}        
       
{
    { foo }}
    {
     % endfor %}
      
      
    
       
                {
     { pagination.page_html|safe }}
