django自制后台左侧导航代码

自定义一个sort.py页面：

写入一下代码：

class lanmusort(object):
    def __init__(self):
        self.arr=[]

    def lanmuget(self,obj):
        for value in obj:
            if value['pid']==0:
                value['lists']=[]
                self.arr.append(value)
                self.lanmuget_two(obj,value['id'],value['lists'])
        del obj
        return self.arr
    def lanmuget_two(self,obj,pid,lists):
        for value in obj:
            if value['pid'] == pid:
                value['lists'] = []
                lists.append(value)
                self.lanmuget_two(obj,value['id'],value['lists'])
    def __del__(self):
        del self.arr

数据库查询页面

view.py:（引入上面的自定义页面）

# 输出左侧栏目列表
left_lanmu = models.AdminRule.objects.order_by('sort').all().values("id","title","name","sort","is_top","pagenumber","pid",)
re_left_lanmu = lanmu.lanmusort()
relanmu = re_left_lanmu.lanmuget(left_lanmu)
