Question

我正在使用udemy的教程。我是关于设置静态文件的部分。 https://www.udemy.com/probar-django-construir-una-aplicacion-web-en-python/learn/v4/overview就是这个链接。

在视频22上显示了如何配置静态文件。

我在教程中配置了所有内容。这比仅从文档，colins，大写'POST'中键入代码更进一步。同样，我的代码与教程完全一样。

关于如何阅读错误消息的任何评论，只看看有用的这些东西也有很好的帮助。

视频是西班牙语，但页面和代码都是英文。

任何人都可以通过查看错误消息或查看来告诉我看看可能出错的教程。

The `urlpatterns` list routes URLs to views. For more information please 
see:
https://docs.djangoproject.com/en/1.10/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))

Answer 1

如果您前往消息来源并浏览the function提出该错误，则会启动：

# django/conf/urls/static.py
def static(prefix, view=serve, **kwargs):
    ...
    if not prefix:
        raise ImproperlyConfigured("Empty static prefix not permitted")

因此，在代码中的某个时刻，您将第一个参数prefix传递给false-y（如空字符串）。查看您的urls.py，您有

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

我猜想STATIC_URL或MEDIA_URL是空的。看起来你宣称是前者，所以可能是后者。

Answer 2

url.py

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

settings.py

MEDIA_URL = '/media/'
STATIC_URL = '/static/'
#/static/imagenes/img1.jpg

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static_pro", "static"),
    #'/var/www/static/',
]

STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static_env", 
"static_root")
MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static_env", 
"media_root")

Answer 3

嘿！！！似乎未创建根媒体文件夹，请先创建超级用户并创建作业，然后将自动创建该文件夹。然后添加媒体网址“ + static（settings.MEDIA_URL，document_root = settings.MEDIA_ROOT）”。

希望！会正常工作。

Answer 4

我遇到了同样的问题，所以我通读了static.py文件，它需要一个前缀...所以我做了这样的事情：

MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')

然后我又重新启动并且没有错误...

不允许使用空静态前缀
