Actually, on GAE, I don't think you have to explicitly define the blob
field at all -- the DAL will automatically create a blob field for each
upload field and store uploaded files in the blob field. So, I think this
should work:
dal_db.define_table('UserImageStore',
Field('profile_image', 'upload'),
Field('upload_ts', 'datetime'),
Field('change_ts', 'datetime'))
dal_db.UserImageStore.insert(
profile_image=dal_db.UserImageStore.profile_image.store(profile_image,
<name
you want to give>),
upload_ts=datetime.now(),
change_ts=datetime.now())
