Question

我正在尝试将媒体目录中的JPG图像加载到我的Django服务器中。

我从STATIC_ROOT加载css没有问题，但是我无法从MEDIA_ROOT访问图像。既不是来自应用程序也不是来自浏览器

我正在使用PILL库在保存之前制作缩略图并对img进行抗锯齿处理，上传运行良好，并将图像复制到我的MEDIA_ROOT中。但该应用程序仍然无法访问它。浏览器中的调试实用程序（Firebug）声明“图像无法加载”，但链接中的URL完全正确。

这是我试图将文件打开到浏览器中的错误：

url是存储在The server tells the problem is in C:\Python27\lib\ntpath.py in join. At line 96 <code> # Join, and ensure there's a separator. assert len(path) > 0变量中的unicode字符串。

应用程序如何正确编写模板，图像在那里，MEDIA_URL已设置且工作正常，但图像是否仍未加载到浏览器中？

这是我的'urls.py'，请问：

img

from django.conf.urls import patterns, include, url
from django.conf import settings

from django.conf.urls.defaults import *
from django.utils.translation import ugettext as _

import os


# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()


urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    (r"^forum/(\d+)/$", "forum.views.forum"),
    (r"^thread/(\d+)/$", "forum.views.thread"),
    (r"^post/(new_thread|reply)/(\d+)/$", "forum.views.post"),
    (r"^reply/(\d+)/$", "forum.views.reply"),
    (r"^new_thread/(\d+)/$", "forum.views.new_thread"),
    (r"^profile/(\d+)/$", "forum.views.profile"),
    (r'^media/(?P<path>.*)$', 'django.views.static.serve'),

    (r"", "forum.views.main"),


)

if settings.DEBUG:
    # serving the media files for dojango / dojo (js/css/...)
    urlpatterns += patterns('',
        (r'^media/(?P<path>.*)$', 'django.views.static.serve',
            {'document_root': os.path.join(os.path.dirname(__file__), "media")}),
    )

当我浏览此视图时，该应用程序运行良好并上传图片，但图片无法加载到视图中，而在其他视图中也是：

from django.conf.urls import patterns, include, url from django.conf import settings from django.conf.urls.defaults import * from django.utils.translation import ugettext as _ import os # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), (r"^forum/(\d+)/$", "forum.views.forum"), (r"^thread/(\d+)/$", "forum.views.thread"), (r"^post/(new_thread|reply)/(\d+)/$", "forum.views.post"), (r"^reply/(\d+)/$", "forum.views.reply"), (r"^new_thread/(\d+)/$", "forum.views.new_thread"), (r"^profile/(\d+)/$", "forum.views.profile"), (r'^media/(?P<path>.*)$', 'django.views.static.serve'), (r"", "forum.views.main"), ) if settings.DEBUG: # serving the media files for dojango / dojo (js/css/...) urlpatterns += patterns('', (r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': os.path.join(os.path.dirname(__file__), "media")}), )

感谢您的时间

Answer 1

您在网址中有django.views.static.serve次来电，第一次未提供document_root，因此假设为None，并在os.path.join上引发了异常

尝试访问静态媒体目录上的任何文件时出现TypeError
