from django import templatefrom django.conf import settingsfrom collections import OrderedDictimport reregister = template.Library()@register.inclusion_tag('menu.html')def menu(request):    menu_dict = request.session[settings.MENU_SESSION_KEY]    order_dict=OrderedDict()    ret=sorted(menu_dict,key=lambda x:menu_dict[x]['weight'],reverse=True)    for i in ret:        order_dict[i] = menu_dict[i]    for r in order_dict.values():        r['class']='hide'        for i in r['children']:            if re.match(r'^{}$'.format(i['url']),request.path_info):                i['class'] = 'active'                r['class']= ''    return {
   'menu_list': order_dict.values()}
