In stead of using the BlobstoreUploadHandler
supplied in AppEngine, I\'d prefer to use a Django view, so I can keep all the urls and view functions together. Howeve
It took me a long time to find, but the content_type: message/external-body
requires extra parameters, to find the actual file, in AppEngine's case, this is the blob-key
. However, Django doesn't support these extra content_type parameters, so they are indeed lost in the process. There seems to be a patch, but I don't think it's in the AppEngine Django version yet.
