split your data into parts for datastore entity 1M limitation.
and combine parts to one file before respond to browser.
@PROPERTY
def Binary():
def fget(self):
if self.size > MAX_BLOD_SIZE and self.binarylist:
bin = StringIO()
for id in self.binarylist:
part = PhotoPart.get_by_id(id)
bin.write(part.binary)
return bin.getvalue()
else:
return self.binary
def fset(self, bin):
length = len(bin)
if length > MAX_BLOD_SIZE:
seq = 0
if not self.is_saved():
self.put()
for i in range(0, length/MAX_BLOD_SIZE+1):
part = PhotoPart()
part.binary = bin[i*MAX_BLOD_SIZE:(i
+1)*MAX_BLOD_SIZE]
part.photo = self
part.seq = seq
part.put()
self.binarylist.append(part.id)
seq += 1
else:
self.binary = bin
return locals()
