导航条添加被选中状态

方法一：在templatetags中的函数添加如下代码

 1 # from django.template import Library
 2 # from django.conf import settings
 3 # 
 4 # register = Library()
 5 # 
 6 # 
 7 # @register.inclusion_tag('menu.html')
 8 # def unicom_menu(request):
 9 #     role = request.unicom_role
10 #     menu_list = settings.UNICOM_MENU[role]
11 
12     for row in menu_list:
13         if row['url'] == request.path_info:
14             row['class'] = "active"
15         else:
16             row.pop('class', None)
17 
18     return {'menu_list': menu_list}

 

方法二：采用deepcoy方式

from django.template import Library
from django.conf import settings
import copy
register = Library()


@register.inclusion_tag('menu.html')
def unicom_menu(request):
    role = request.unicom_role
    menu_list = copy.deepcopy(settings.UNICOM_MENU[role])

    for row in menu_list:
        if row['url'] == request.path_info:
            row['class'] = "active"
        # else:
        #     row.pop('class', None)

    return {'menu_list': menu_list}
