Django 1.10网址弃用

有一些弃用警告.这是问题所在:

RemovedInDjango110Warning: Support for string view arguments to url()
is deprecated and will be removed in Django 1.10 
(got django.views.static.serve). Pass the callable instead.
'document_root': settings.MEDIA_ROOT,

这是网址:

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^ckeditor/', include('ckeditor_uploader.urls')),
    url(r'^media/(?P.*)$', 'django.views.static.serve', {
            'document_root': settings.MEDIA_ROOT,
        }),
    url(r'^post/(\d+)$', post),
    url(r'^(\w+)$', category),
    url(r'^$', category),
]

怎么解决？谢谢你的时间.

用实际视图函数替换字符串中的函数路径.例如:

from django.views.static import serve
...
url(r'^media/(?P.*)$', serve, {
        'document_root': settings.MEDIA_ROOT,
    }),
