點擊到最後一頁，效果如下：

但實際上只有9頁，判斷next（即當前頁是否存在下一頁）標籤時 加 3 溢出 到10頁。
1、要求顯示的頁碼範圍數為3,不足的為2或者1；
請教該如何處理？

在Paginator上再封裝一層Spagination ,Views調用

obj = Model.object.filter(條件)pagin = Spagination.wraper(obj, pageSize, page)return pagin

Spagination類代碼

#coding=utf-8from django.core.paginator import Paginatorclass Spagination(object):    def __init__(self, total, page=1, perpage=10):        self.total = total        self.pages = self.total / perpage + 1 if (self.total % perpage) > 0 else self.total / perpage        self.page = page        self.perpage = perpage        self.prev_num = page-1 if page > 1 else None        self.next_num = page+1 if page*perpage < total else None        self.has_prev = True if self.prev_num else False        self.has_next = True if self.next_num else False        self.visible_pages = self.iter_pages()    def prev(self):        if self.prev_num:            return Spagination(self.total, page=self.page-1, perpage=self.perpage)        raise 'There is no prev page!'    def next(self):        if self.next_num:            return Spagination(self.total, page=self.page+1, perpage=self.perpage)        raise 'There is no next page!'    def iter_pages(self, left_edge=5, right_edge=4, all=9):        left_list, right_list = [], []        for p in range(1,left_edge):            if self.page - p > 0:                left_list.insert(0, self.page - p)        for p in range(1,right_edge):            if self.page + p <= self.pages:                right_list.append(self.page + p)        if len(left_list) < left_edge and right_list:            for i in range(all-len(left_list)-len(right_list)-1):                if right_list[-1]+1 <= self.pages:                    right_list.append(right_list[-1]+1)        if len(right_list) < right_edge and left_list:            for i in range(all-len(left_list)-len(right_list)-1):                if left_list[0]-1 > 0:                    left_list.insert(0, left_list[0]-1)        return left_list+[self.page]+right_list    def setItems(self, items):        self.items = items    @classmethod    def wraper(cls, objs, limit, current_page):        paginator = Paginator(objs, limit)        items = paginator.page(current_page)        pagin = Spagination(paginator.count, current_page, limit)        pagin.setItems(items)        return pagin

template代碼

    {%if pagin.has_prev %}        上頁    {%endif%}    首頁    {%for p in pagin.visible_pages%}        {%if p != 1 and p != pagin.pages%}            {{p}}        {%endif%}    {%endfor%}    尾頁    {%if pagin.has_next %}        下頁    {%endif%}

可以再加一層判斷，判斷是否超出
