Heroku + S3 上的 Django-Filebrowser 500 错误

Question

在 POST 时在 Heroku 上使用 Filebrowser 和 S3 时出现 500 错误。我已经添加了堆栈跟踪和模型信息 :) 这可能是 S3 问题还是与 Filebrowser 有关？

来自终端的堆栈跟踪：

这是模型：

file = FileBrowseField("HTML or ZIP File", max_length=256, blank=True, null=True, extensions=[".zip",".html"], help_text="Upload an html file or a zip file of banners")

def save(self, *args, **kwargs):
    self.slug = slugify(self.name)

    super(BannerCode, self).save(*args, **kwargs)

def __unicode__(self):
    return self.name

def post_upload_callback(sender, **kwargs):
    if kwargs['file'].extension == ".zip":
        path = kwargs['path'] 
        thefile = kwargs['file'] 

        # Convert file and dir into absolute paths
        fullpath = os.path.join(settings.MEDIA_ROOT, '' + thefile.path)
        dirname = os.path.dirname(fullpath)

        # Get a real Python file handle on the uploaded file
        fullpathhandle = open(fullpath, 'r') 

        # Unzip the file, creating subdirectories as needed
        zfobj = zipfile.ZipFile(fullpathhandle)
        for name in zfobj.namelist():
            if name.endswith('/'):
                try: # Don't try to create a directory if exists
                    os.mkdir(os.path.join(dirname, name))
                except:
                    pass
            else:
                outfile = open(os.path.join(dirname, name), 'wb')
                outfile.write(zfobj.read(name))
                outfile.close()

        # Now try and delete the uploaded .zip file and the  __MACOSX dir if they exist.
        try:
            os.remove(fullpath)
        except:
            pass

        try:
            osxjunk = os.path.join(dirname,'__MACOSX')
            shutil.rmtree(osxjunk)
        except:
            pass                

# Signal provided by FileBrowser on every successful upload. 
filebrowser_post_upload.connect(post_upload_callback)

我什至不知道如何开始调试这个。有人对此有见解吗？谢谢！

忘记回答了……

文件浏览器与 django-storages 不兼容。
