urls.py 如果有帮助：

from django.conf.urls.defaults import *
from outfits.views import *
import settings

urlpatterns = patterns("",
    # Outfits
    url(r'^$', outfit_list, name='outfit_list'),
    url(r'^new/$', outfit_create, name='outfit_create'),
    url(r'^detail/(\d+)/$', outfit_detail, name='outfit_detail'),
    url(r'^update/(\d+)/$', outfit_update, name='outfit_update'),
    url(r'^delete/(\d+)/$', outfit_delete, name='outfit_delete'),
    # Products
    url(r'^detail/(\d+)/add/confirm/$', product_confirm, name='product_confirm'),
    url(r'^outfit_displayImg/$', outfits_displayImg),
    url(r'^detail/(\d+)/add/$', product_add, name='product_add'),
    url(r'^detail/(\d+)/update/(\d+)$', product_update, name='product_update'),
    url(r'^detail/(\d+)/delete/(\d+)$', product_delete, name='product_delete'),
)

if settings.DEBUG:
    urlpatterns += patterns('',
        url(r'^site_media/media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

因此，在我的模板{{MEDIA_URL}} {{p.images}}中返回正确的网址 http://127.0.0.1:8000/site_media/media/products/co_macysLogo3.gif ，但当我打开它时，我得到 Page Not Found 。

文件在那里，所以我不确定为什么抱怨。我已经看了3个或4个与我类似的问题但是他们的答案都没有解决我的问题。奇怪我的{{STATIC_URL}}工作得很好，但不是{{MEDIA_URL}}。我当然会使用STATIC_URL，只是为了让我的应用程序工作，但不幸的是Django的ImageField upload_to参数只将图像上传到媒体文件夹。

更新：将MEDIA_ROOT更改为MEDIA_ROOT = os.path.join(PROJECT_ROOT, "static")并通过{{STATIC_URL}} {{p.images}}调用我的图片解决了这个问题。我希望有更好的方法。我仍然不明白为什么Django不能从MEDIA_URL中提供图像文件。

5 个答案:

答案 0 :(得分：7)

在urls.py

中的if settings.DEBUG下添加以下行 
(r'^site-media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes':True}),

或设置MEDIA_URL = "/media/"

staticfiles提供静态文件，对于媒体文件，您必须明确指定服务路径。

更新

使用文件后端存储媒体文件时，例如ImageField(upload_to='product')，将在MEDIA_ROOT/product/foo中创建名为foo的文件;页面中文件的网址为MEDIA_URL/product/foo;在开发服务器上，您必须配置urls.py以便为'MEDIA_URL/(?<path>.*)$'提供请求，其中路径为product/foo。

答案 1 :(得分：6)

在我的一个项目中，只是一个简单的例子说明了什么对我有用 settings.py 

MEDIA_ROOT = os.path.join(PROJECT_ROOT, 'site_media', 'media')
MEDIA_URL = '/site_media/media/'
STATIC_ROOT = os.path.join(PROJECT_ROOT, 'site_media', 'static')
SITE_MEDIA_URL = '/site_media/'
STATIC_URL = '/site_media/'
ADMIN_TOOLS_MEDIA_URL = '/site_media/'
ADMIN_MEDIA_PREFIX = posixpath.join(STATIC_URL, "admin/")
STATICFILES_DIRS = (os.path.join(PROJECT_ROOT, 'site_media'),)

urls.py 

if settings.SERVE_MEDIA:
    urlpatterns += patterns("",
        (r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
            {'document_root': settings.STATIC_ROOT, 'show_indexes': True }),
        (r'^static/(?P<path>.*)$', 'django.views.static.serve',
            {'document_root': settings.STATIC_ROOT, }),

models.py 

image = ImageField(upload_to='products/product_type', blank=True, null=True)

模板（简化）

<img src="{{object.image.url}}" >

答案 2 :(得分：5)

在urls.py文件中，您需要执行以下操作：

from django.conf import settings
from django.conf.urls.static import static


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

答案 3 :(得分：0)

网址格式与您的MEDIA_URL不一致。您可以将设置中的MEDIA_URL更改为“/ media /”以匹配您的网址设置。

答案 4 :(得分：0)

我认为这是真的和好的

(r'^site-media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': 'media/your/path'}),

之后检查您的文件是否存在于此路径中

表示您必须在媒体路径中有products/co_macysLogo3.gif
