我们的stark组件用的我们的分页组件，没有重新写

 

 

 

下面直接看下分页的代码

分页的代码在什么实用用呢？应该list_url这个函数把过滤和搜索后的数据传递个showlist这个类，然后这个类在根据这些要显示的数据在进行分页

class Showlist(object):    def __init__(self,config,request,new_list,new_data_list):        self.config = config        self.request = request        self.new_list = new_list        self.new_data_list = new_data_list        # 分页显示        count = self.new_data_list.count()        current_page = int(request.GET.get("p",1))        per_page_num = 3        base_url = request.path_info        parms = request.GET        self.page_str = page.page_helper(count=count,current_page=current_page,per_page_num=per_page_num,base_url=base_url,parms=parms)
