【问题描述】：

我对 django 比较陌生。我正在尝试将 audiotracks 包与我的项目集成。我正在尝试集成 audiotracks 包，但出现 NoReverseMatch 错误。文档说明..

将audiotracks 添加到您的应用 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

编辑settings.py 并将audiotracks 添加到您的列表中 INSTALLED_APPS。然后同步你的数据库::

$ python manage.py syncdb

编辑你的 ROOT_URLCONF_ 并添加一段类似于::

的代码

urlpatterns += patterns('',
    # Here we mount the app under /music. Feel free to use something else
    url("^music", include("audiotracks.urls")),
    # Some URLs require a Django username
    url("^(?P<username>[\w\._-]+)/music", include("audiotracks.urls")),
)

访问 URL /music/upload 上传您的第一首曲目。

当我尝试访问音乐/上传时发生错误..

这是完整的追溯。

【问题讨论】：

您不可能遵循该指示；除此之外，patterns 在 Django 1.11 中不再存在。请出示您的完整 urls.py。
感谢您指出这一点。我添加了第二个网址，它起作用了..@DanielRoseman

标签： python django audio-player

【解决方案1】：

from django.conf.urls import url, include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from django.views.static import serve
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^account/', include('account.urls')),
    url(r'^music/', include('music.urls')),
    url(r'^music/', include('audiotracks.urls')),
    url(r'^(?P<username>[\w\._-]+)/music', include('audiotracks.urls')),
]

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

if settings.DEBUG:
    urlpatterns += [
        url(r'^site_media/(?P<path>.*)$', serve, {
            'document_root': settings.MEDIA_ROOT
        })
    ]
    urlpatterns += staticfiles_urlpatterns()
