django中的inclusion_tag配置和实现

###
在settings.py中设置libraries
###
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
            'libraries':{
17                 "manage_menu_list": "mac.templatetags.inclusion_tag_mac",
                 自定的tag函数       自定的tag函数的所在文件路径
            },
        },
    },
]



###
"mac.templatetags.inclusion_tag_mac"文件下自定的tag函数
###
from django.template import Library
from django.urls import reverse
register = Library()

                            标签动态渲染
@register.inclusion_tag('manage_menu_list.html')
def manage_menu_list(request):
    data_list = [
        {'title': '首页', 'url': reverse('mac_home')},
        {'title': '生成MAC', 'url': reverse('input_mac')},
        {'title': 'MAC下载', 'url': reverse('download_details')},
    ]
    for item in data_list:
        if request.path_info == item['url']:
            item['class'] = 'active'
    return {'data_list': data_list}
    
###
在其他模板中首先导入文件inclusion_tag_mac
###    
{% load inclusion_tag_mac %}
....
{% manage_menu_list request %}
....
