菜单的排序:(给菜单设置权重,权重高的让他显示在上面)

from django import template
from django.conf import settings
from collections import OrderedDict
import re

register = 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()}

menu.html文件

<div class="multi-menu">

    {% for menu in menu_list %}
        <div class="item">
            <div class="title"><i class="fa {{ menu.icon }}"></i> {{ menu.title }}</div>
            <div class="body">
                {% for child in menu.children %}
                    <a href="{{ child.url }}""> {{ child.title }} </a>
                {% endfor %}
            </div>
        </div>
    {% endfor %}
