如何在应用程序目录中获取 django 静态文件？

Question

I have some doubts about accessing django's static files.

VERSION: 1.8.4
VARs in settings.py:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
STATIC_ROOT = join(PROJECT_ROOT, 'static')
STATIC_URL = '/static/'STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
)


TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            # insert your TEMPLATE_DIRS here
            # os.path.join(BASE_DIR, 'templates').replace('\\', '/')
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
                # list if you haven't customized them:
                'django.contrib.auth.context_processors.auth',
                'django.template.context_processors.debug',
                'django.template.context_processors.i18n',
                'django.template.context_processors.media',
                'django.template.context_processors.static',
                'django.template.context_processors.tz',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

1. setting STATICFILES_DIRS, and adding django.template.context_processors.static to context_processors in TEMPLATES , so I can use 'static' tag in template. A src tag like: src="{{STATIC_URL}}js/example.js" or src="{% static 'js/example.js' %}" will generate a url to http://myhost/static/js/example.js .

2. If I want load static files in app directory, what should I do? As my understanding of django-official-doc,
   STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.AppDirectoriesFinder', 'django.contrib.staticfiles.finders.FileSystemFinder', )
   the finders will search app/static in default, but if a src="static/js/example.js" in app/templates/index.html , the server will return a 404 code. Until I add urlpatterns += staticfiles_urlpatterns() to app/urls.py .

What i want to know is:

1. Why 404? When load static file form app/static without urlpatterns += staticfiles_urlpatterns() .

2. If I want to get static file in app/static , how to write url in a flexible way? cause {{STATIC_URL}} or {% static %} both point to project/static.

I have spend hours in reading related post on stackoverflow. Any help would be sooo greatly appreciated.

Answer 1

Add the following code in your projects settings.py

STATIC_URL = '/public/static/'
STATICFILES_DIRS = (
    location('static'),
)
STATIC_ROOT = location('public/static')

Then you should be able to access the contents in the url like :

http://127.0.0.1:8000/public/static/js/bootstrap.min.js

Let say you have project named MyProject provided you must have a folder named

Myproject->public->static->js->bootstrap.min.js

inside your projects directory .

and in your webpages you can simply refer to it by :

<link href="{% static 'css/bootstrap.min.css' %}" rel="stylesheet">

Hope the idea is very clear . In Case of doubts revert back.
