1、创建数据库信息

        class UserList(models.Model):
            username = models.CharField(max_length=32)
            age = models.IntegerField()

2、创建URL

        from app01 import views
        urlpatterns = [
            url(r'^admin/', admin.site.urls),
            url(r'^user_list/', views.user_list),
        ]


3、定义一个Pager类，处理页数换算

class Pager(object):
    def __init__(self, current_page):
        self.current_page = int(current_page)

    @property
    def start(self):
        return (self.current_page - 1) * 10

    @property
    def end(self):
        return self.current_page * 10

    def page_str(self, all_item, base_url):
        all_page, div = divmod(all_item, 10)
        if div > 0:
            all_page += 1

        pager_list = []
        if all_page <= 11:
            start = 1
            end = all_page
        else:
            if self.current_page <= 6:
                start = 1
                end = 12
            else:
                start = self.current_page - 5
                end = self.current_page + 6
                if self.current_page + 6 > all_page:
                    start = all_page - 11
                    end = all_page + 1

        for i in range(start, end):
            if i == self.current_page:
                temp = '%d' % (base_url, i, i,)
            else:
                temp = '%d' % (base_url, i, i)
            pager_list.append(temp)

        # pre_next

        if self.current_page > 1:
            pre_page = 'pre_next' % (base_url, self.current_page - 1)
        else:
            pre_page = 'pre_next'
        # next
        if self.current_page >= all_page:
            next_page = 'next'
        else:
            next_page = 'next' % (base_url, self.current_page + 1)
        pager_list.insert(0, pre_page)
        pager_list.append(next_page)
        return mark_safe("".join(pager_list))

4、创建视图 ，并导入上面创建的Pager类  

        def user_list(request):
            current_page=request.GET.get('page',1)
            page_obj = page.Pager(current_page)
            result = models.UserList.objects.all()[page_obj.start:page_obj.end]
            all_item = models.UserList.objects.all().count()
            pager_str = page_obj.page_str(all_item, "/user_list/?page=")
            return  render(request, 'user_list.html', {'result': result, 'pager_str': pager_str})

5、创建前端user_list.html调用后台信息。




   
   
   


   


        {% for line in result %}
       
           
           
       
        {% endfor %}

   
` line`.`username `` line`.`age `

   

        {{ pager_str|safe }}
