13721	pass extra content-type values to file upload handlers	Waldemar Kornewald	mvschaik	"Currently, file upload handlers can only get the actual content type and charset, but App Engine's Blobstore file service passes a few extra vales to the content type which are needed to get the uploaded file's identifier (""blob-key""). Here's a sample snippet of an HTTP upload request's POST data:

{{{
--===============0880245784==
Content-Type: message/external-body; blob-key=""WEexn9L82wky30ADBOWqYA==""; access-type=""X-AppEngine-BlobKey""
MIME-Version: 1.0
Content-Disposition: form-data; name=""file""; filename=""django-nonrel.diff""

Content-Type: application/octet-stream
MIME-Version: 1.0
Content-Length: 8522
content-type: application/octet-stream
content-disposition: form-data; name=""file""; filename=""django-nonrel.diff""
X-AppEngine-Upload-Creation: 2010-06-08 15:34:32.685000


--===============0880245784==--
}}}

The attached patch changes the file upload handling code such that it passes a dictionary with all extra content type arguments to the upload handler. With this I was able to successfully upload files to a model's FileField via a ModelForm."	New feature	closed	File uploads/storage	dev	Normal	fixed		timograham@…	Accepted	1	0	0	0	1	0
