 3 ###
 4 TEMPLATES = [
 5     {
 6         'BACKEND': 'django.template.backends.django.DjangoTemplates',
 7         'DIRS': [os.path.join(BASE_DIR, 'templates')],
 8         'APP_DIRS': True,
 9         'OPTIONS': {
10             'context_processors': [
11                 'django.template.context_processors.debug',
12                 'django.template.context_processors.request',
13                 'django.contrib.auth.context_processors.auth',
14                 'django.contrib.messages.context_processors.messages',
15             ],
16             'libraries':{
17                 "manage_menu_list": "mac.templatetags.inclusion_tag_mac",
18                  自定的tag函数       自定的tag函数的所在文件路径
19             },
20         },
21     },
22 ]
23 
24 
25 
26 ###
27 "mac.templatetags.inclusion_tag_mac"文件下自定的tag函数
28 ###
29 from django.template import Library
30 from django.urls import reverse
31 register = Library()
32 
33                             标签动态渲染
34 @register.inclusion_tag('manage_menu_list.html')
35 def manage_menu_list(request):
36     data_list = [
37         {'title': '首页', 'url': reverse('mac_home')},
38         {'title': '生成MAC', 'url': reverse('input_mac')},
39         {'title': 'MAC下载', 'url': reverse('download_details')},
40     ]
41     for item in data_list:
42         if request.path_info == item['url']:
43             item['class'] = 'active'
44     return {'data_list': data_list}
45     
46 ###
47 在其他模板中首先导入文件inclusion_tag_mac
48 ###    
49 {% load inclusion_tag_mac %}
50 ....
51 {% manage_menu_list request %}
52 ....
