Django 自定义标签和过滤器 错误解决

1.错误信息 ：is not a registered tag library. Must be one of:

   TemplateSyntaxError at /my_customer_tags/
	'admin_tags' is not a registered tag library. Must be one of:
	admin_list
	admin_modify
	admin_static
	admin_urls
	cache
	custom_tags
	i18n
	kingadmin_tags
	l10n
	log
	static
	staticfiles
	tz

2.确定是正常创建的过滤器和自定义标签

    1.文件夹名称为“templatetages"
    2.register = template.Library()

3.解决方法

   setting.py
   TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR,"mydjangoapp/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':{ 
				   'my_filter':'mydjangoapp.templatetages.my_filter',   # 名：文件路径用点链接
				},
	        },
	    },
	]
