hi,
im having issues when i upload many (50-100) files at on a web based upload
queue.
i have 2 handlers. the FileUploadHandler saves the binary, checks if its saved
and redirects to the
RedirectAfterUpload which creates a json dict for the uplaod js to tell that
the uplaod is done.
the issue is that sometimes i get a NoneType when i try to get the asset on the
second handler.
how is this possible if i checked that it was saved in the first handler and it?
i also use entity groups and i tried different ways of getting and putting the
binary by key.
sometimes i also get a redirect to temporary-blobstore-error.appspot.com which
is really annoying.
here the 2 handlers:
class FileUploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self, tags=None):
uploads = self.get_uploads()
if uploads:
binary = uploads[0]
bin = Binary(parent = imageapp_key,
blob = binary,
filename = binary.filename,
size = binary.size)
# put the entity
bin.put()
# make a test get operation to see if the
# asset is saved.
testget = db.get(bin.key())
if not testget or not bin.is_saved():
import logging
logging.warning('*********** bin is not saved!')
return self.error(500)
key = str(bin.key())
self.redirect('/assets/api/upload/%s.json' %key)
class RedirectAfterUpload(RequestHandler):
def get(self, key):
asset = db.get(key)
# get the asset
if not asset:
asset = Binary.get(key)
# after the second get the get
# still returns a None
if not asset:
logging.warning('still no asset after second get')
return self.error(500)
data = dict(name = asset.filename,
thumbnail = asset.serving_url,
size = asset.size)
self.response.headers["Content-Type"] = "application/x-javascript"
self.response.out.write(jsonify(data))
i don't understand what it could be.
thx
andreas
