I am working on the same thing but for sounds. I used the experimental file
writing to blobstore liker this:
def blobstore_upload(form):
from google.appengine.api import files
from google.appengine.ext import blobstore
if request.env.web2py_runtime_gae and form.vars.file:
# Create the file
file_name =
files.blobstore.create(mime_type='application/octet-stream')
# Open the file and write to it
with files.open(file_name, 'a') as f:
f.write(form.vars.file.file.read())
# Finalize the file. Do this before attempting to read it.
files.finalize(file_name)
# Get the file's blob key
form.vars.blob_key = files.blobstore.get_blob_key(file_name)
form.vars.file = None
@auth.requires_login()
def upload():
return dict(form=crud.update(db.sounds, a0,
onvalidation=blobstore_upload, message=T('Upload complete!')))
def download_blob():
from google.appengine.ext import blobstore
sound = db.sounds(a0)
if not sound:
raise HTTP(404)
blob_info = blobstore.BlobInfo.get(sound.blob_key)
return response.stream(blob_info.open())
Now I am hitting the 10Mb limit so I need to experiment some more with
create_upload_url.
