django 1.11 自定义分页功能的实现

在WEB中很多时候是免不了要分页的，如果我们的数据太多了，分出来6000多页或者更多的时候，用django自带的分页功能就不好看了，所以我们来自定义一下。我是参考http://www.cnblogs.com/nulige/p/6558207.html这篇文章的，不过如果照着抄的话，会报错的，我修改了几个地方，实现效果如下图：

最后代码：

urls.py的代码就不写了

views.py(我把这分页包装了一下，便于移植)：

class CustomPaginator(Paginator):
    def __init__(self, current_page, per_pager_num, *args, **kwargs):
        self.current_page = int(current_page)
        self.per_pager_num = int(per_pager_num)
        super(CustomPaginator, self).__init__(*args, **kwargs)

    def pager_num_range(self):
        if self.num_pages < self.per_pager_num:
            return range(1, self.num_pages + 1)

        half_part = int(self.per_pager_num / 2)
        if self.current_page <= half_part:
            return range(1, self.per_pager_num + 1)

        if (self.current_page + half_part) > self.num_pages:
            return range(self.num_pages - self.per_pager_num + 1, self.num_pages)
        return range((self.current_page - half_part), (self.current_page + half_part + 1))

def pagedivide(request, USER_LIST):
        try:
            current_page = request.GET.get('page')
            paginator = CustomPaginator(current_page, 11, USER_LIST, 10)
        except:
            current_page = 1
            paginator = CustomPaginator(current_page, 11, USER_LIST, 10)

        try:
            paginator = paginator.page(current_page)
        except PageNotAnInteger:
            paginator = paginator.page(1)
        except EmptyPage:
            paginator = paginator.page(paginator.num_pages)
        return paginator

html模板：

                                  {% for re in users.object_list %}
                                      {% if re.is_target %}
