Question

我的项目包含三个不同的应用程序。他们使用通用settings.py：

# -*- coding: utf-8 -*-
import os

SECRET_KEY = '123456'

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

DEBUG = True

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'whitenoise.runserver_nostatic',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'django.contrib.humanize',
)

MIDDLEWARE_CLASSES = (
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
)



INTERNAL_IPS = ('127.0.0.1',)


EMAIL_BACKEND = "sgbackend.SendGridBackend"
SENDGRID_API_KEY = "*******"

TEMPLATE_DIRS = (
    os.path.join(BASE_DIR, 'templates'),
    os.path.join(BASE_DIR, 'templates/'),
    )
TEMPLATE_CONTEXT_PROCESSORS = (
    'django.contrib.auth.context_processors.auth',
    'django.core.context_processors.request',
    'django.core.context_processors.debug',
    'django.core.context_processors.i18n',
    'django.core.context_processors.media',
    'django.core.context_processors.static',
)
TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
)

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
        'DEFAULT_MIDDLEWARE_ALIAS': 'default',
        'DEFAULT_MIDDLEWARE_SECONDS': '300',
        'DEFAULT_MIDDLEWARE_KEY_PREFIX': '',
    }
}

PASSWORD_HASHERS = (
    'django.contrib.auth.hashers.SHA1PasswordHasher',
)

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)

你可以看到 - 没什么特别的。每个应用都有其他app#_settings.py文件，该文件扩展了一般settings.py。

所有这些应用都在urls.py：

中包含此（最后）行

] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

我处于开发模式，DEBUG设置为True。 APP1和APP2能够运行开发服务器，而我第三个APP有问题，过去两天我试图弄清楚问题究竟是什么，但没有成功。当我运行开发服务器（runserver --settings=app3_settings）时，我收到此错误：

AtributeError: module object has no attribute STATIC_URL

以下是app3_settings.py :( app1和app2的设置非常相似，几乎没有区别）

# -*- coding: utf-8 -*-
from settings import * 

SECRET_KEY = '*************************************************'

ALLOWED_HOSTS = [
    'localhost', 
    '127.0.0.1',
    ]

INSTALLED_APPS += (
    'storages',
    'app3',
    'el_pagination',
    'debug_toolbar',
)

ROOT_URLCONF = 'app3.urls'

WSGI_APPLICATION = 'app3.wsgi.application'

DEFAULT_FROM_EMAIL = 'web@example.com'

MANAGERS = ADMINS

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
        'DEFAULT_MIDDLEWARE_ALIAS': 'default',
        'DEFAULT_MIDDLEWARE_SECONDS': '300',
        'DEFAULT_MIDDLEWARE_KEY_PREFIX': '',
    }
}

PASSWORD_HASHERS = (
    'django.contrib.auth.hashers.SHA1PasswordHasher',
)


# AMAZON S3 & CLOUDFRONT SERVING MEDIA FILES
AWS_S3_HOST = 's3.eu-central-1.amazonaws.com'
AWS_STORAGE_BUCKET_NAME = 'mybucket'
AWS_CLOUDFRONT_DOMAIN = 'example.cloudfront.net'
AWS_ACCESS_KEY_ID = "*************"
AWS_SECRET_ACCESS_KEY = "************************"
MEDIAFILES_LOCATION = 'app3/media'
MEDIA_ROOT = '/%s/' % MEDIAFILES_LOCATION
MEDIA_URL = '//%s/%s/' % (AWS_CLOUDFRONT_DOMAIN, MEDIAFILES_LOCATION)
DEFAULT_FILE_STORAGE = 'app3.custom_storages.MediaStorage'

# WHITENOISE SERVING STATIC FILES
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
STATIC_ROOT = os.path.join(BASE_DIR, 'project/static/app3') 
STATIC_URL = '/static/'

如您所见，我已正确声明STATIC_URL，STATIC_ROOT，MEDIA_URL和MEDIA_ROOT。我再次强调 - APP1＆amp; APP2使用完全相同的概念，但在尝试使用它们运行开发服务器时我没有收到此错误，所以我不明白这一点。

我尝试将app3_settings.py的这一部分复制到settings.py：

# AMAZON S3 & CLOUDFRONT SERVING MEDIA FILES
AWS_S3_HOST = 's3.eu-central-1.amazonaws.com'
AWS_STORAGE_BUCKET_NAME = 'mybucket'
AWS_CLOUDFRONT_DOMAIN = 'example.cloudfront.net'
AWS_ACCESS_KEY_ID = "*************"
AWS_SECRET_ACCESS_KEY = "************************"
MEDIAFILES_LOCATION = 'app3/media'
MEDIA_ROOT = '/%s/' % MEDIAFILES_LOCATION
MEDIA_URL = '//%s/%s/' % (AWS_CLOUDFRONT_DOMAIN, MEDIAFILES_LOCATION)
DEFAULT_FILE_STORAGE = 'app3.custom_storages.MediaStorage'

# WHITENOISE SERVING STATIC FILES
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
STATIC_ROOT = os.path.join(BASE_DIR, 'project/static/app3') 
STATIC_URL = '/static/'

然后服务器就可以启动了。但是我不确定为什么我必须在settings.py和app#_settings.py中重复这些行，当app1和app2使用相同的设置时它们没有问题。

如果重要，请manage.py：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

另外，我对每个应用都有单独的wsgi.py，看起来像这样（'app＃_settings'是应用之间的唯一区别）：

import os
import sys
from whitenoise.django import DjangoWhiteNoise
sys.path.append('/home/user/public_html/project')

os.environ['DJANGO_SETTINGS_MODULE'] = 'app#_settings'

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
application = DjangoWhiteNoise(application)

Django - AtributeError：模块对象没有属性STATIC_URL
