Django how to resolve 404 error with files from static?

Question

Django

I recently started learning the Django framework and created my first project by following the tutorial and including the style file in base.html

<link rel="stylesheet" type="text/css" href="{% static 'style/style.css' %}">

encountered error [16/May/2020 17:34:41] "GET /static/css/main.css HTTP/1.1" 404 1662 on the command line when starting the server.

Contents of the settings.py file

Answer 1

I ran into a similar problem while developing on a laptop.
My decision.

LOCAL_MACHINE_DEV = os.getenv("LOCAL_MACHINE_DEV") == "1"

if LOCAL_MACHINE_DEV:
    STATICFILES_DIRS = ["/my/project/static"]
else:
    STATIC_ROOT = os.path.join(PROJECT_PATH, "static")

Answer 2

in urls what? Need to add

if settings.DEBUG:
        urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

Answer 3

and, why do you need such a porridge-confusion - well, in everything ....?

Answer 4

What do you think it returns:
os.path.dirname(__file__)
It will return the location of the settings.py file , which is one level up from static .
As a result, you will get a directory that is, as it were, in the directory along with the settings.py file, and it is, as it were, very different from the desired one.
