不正确配置/空静态前缀不允许 - Django [英] ImproperlyConfigured at / Empty static prefix not permitted - Django

问题描述

我正在使用Django上传/显示图像。

I'm working on uploading/displaying images with Django.

该网站部署在Heroku上。

The website is deployed on Heroku.

按照此教程，我能够成功上传图片。

Following this tutorial I was able to successfully upload images.

但是，图片没有显示在模板中。

However, the images weren't being displayed in the template.

然后我了解到我的urls.py应该在末尾有这一行：

I then learned that my urls.py should have this line at the end:

+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

我把这个添加到我的urls.py的末尾，但是现在我得到这个错误： p>

I added this to the end of my urls.py but now I'm getting this error:

ImproperlyConfigured at / Empty static prefix not permitted

我的settings.py中有MEDIA_URL和MEDIA_ROOT，并且都不为空。

I have MEDIA_URL and MEDIA_ROOT in my settings.py and neither are empty.

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

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

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://example.com/media/", "http://media.example.com/"
MEDIA_URL = '/media/'

为什么会出现此错误，我该如何解决？

Why is this error happening and how would I fix it?

我认为是我的urls.py的相关部分：

Here's what I think is the relevant part of my urls.py:

from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
import notifications
admin.autodiscover()

urlpatterns = patterns('',
    ....urls......

) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

推荐答案

我在我的urls.py中添加了相同的行，并得到与您相同的错误。

I added the same line in my urls.py and got the same error as you.

+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

文档 here 表示使用 settings.STATIC_URL 和 settings.STATIC_ROOT

我将其更改为文档版本

urlpatterns = patterns('',
    ....urls......

) + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

，错误消失了！

我检查了我的设置文件，确认 settings.MEDIA_URL 和 settings.MEDIA_ROOT 都被正确定义。之后我调整了urls.py回到使用 settings.MEDIA_URL 和 settings.MEDIA_ROOT 。一切都按预期工作。

I checked my settings file and made sure settings.MEDIA_URL and settings.MEDIA_ROOT were both defined correctly. Later I adjusted urls.py back to using settings.MEDIA_URL and settings.MEDIA_ROOT. Everything worked as expected.

这些是我的settings.py文件的相关部分：

These are the relevant parts of my settings.py file:

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

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.6/howto/static-files/

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(REPOSITORY_ROOT, 'static/')

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

我认为 MEDIA_URL 设置不正确
