Hey folks, I'm learning the new Cloud Storage and question how to I migrate
my app with a least friction.
Now I'm using this sample piece of code to save images:
from google.appengine.api import images, files
def upload(ext, stream):
file_name = files.blobstore.create(mime_type=mimetypes.types_map[ext])
with files.open(file_name, 'a') as f:
f.write(stream.getvalue())
files.finalize(file_name)
return images.get_serving_url(files.blobstore.get_blob_key(file_name))
Which I'm thinking to change to the next:
def upload(ext, stream):
filename = "/images/my_file"
with gcs.open(filename, 'w') as f:
f.write(stream.getvalue())
# Blobstore API requires extra /gs to distinguish against blobstore
files.
blobstore_filename = '/gs' + filename
# This blob_key works with blobstore APIs that do not expect a
# corresponding BlobInfo in datastore.
blob_key = blobstore.create_gs_key(blobstore_filename)
return images.get_serving_url(blob_key)
Which seems to work.
The problem that in the old version I don't have to worry about filenames,
Files API job was to assign me one. Now I need to give a name myself. Any
way the new api should do it for me? Or maybe I should just hash the file.
