project does not recognize custom filter templatetags when deploying(Django + uwsgi + nginx )

Question

When a personal project is deployed to a ubuntu server (16.04), the command ( python manage.py runserver 0.0.0.0:8000) can be used to access the project on the web page, but the static file is not loaded. However, when running with the （uwigs） command, the error was reported to be inaccessible.

（I don't know if it is a network problem, the uploaded image can not be displayed, so I reused the code instead, I hope you can understand my problem and help me, thank you）

When I run the command in Xshell：

# The web page can be opened normally, but the static file is not loaded.
(django-env-py3) root@li:/srv/xfz# python manage.py runserver 0.0.0.0:8000

Run the uwsgi command page to report an error

(django-env-py3) root@li:/srv/xfz# uwsgi --ini xfz_uwsgi.ini 

Error messages：

# http://192.168.164.128/
TemplateSyntaxError at /
'news_filters' is not a registered tag library. 

I have used some methods, add "libraries" in settings,But after running the uwsgi command, the page is reported incorrectly.

TEMPLATES = [
    {
        --snip--
            # 配置模板的static标签；
            'builtins': [
                'django.templatetags.static'
            ],
            'libraries':{
                'news_filters': 'apps.news.templatetags.news_filters',
                'payinfo_filters': 'apps.payinfo.templatetags.payinfo_filters'
            }
        },
    },
]

Error message

# http://192.168.164.128/

Invalid template library specified. ImportError raised when trying to load 'apps.news.templatetags.news_filters': No module named 'apps.news.templatetags'

I don't know if you can understand my problem. Please help me if you can. Thank you.

Try

TEMPLATES = [
    {
        --snip--
            # 配置模板的static标签；
            'builtins': [
                'django.templatetags.static'
            ],
            'libraries':{
                'news_filters': 'news.templatetags.news_filters',
                'payinfo_filters': 'payinfo.templatetags.payinfo_filters'
            }
        },
    },
]

I'm not sure why it's not automatically resolving this for you, it looks like you have done everything correctly
