#appengine

my app uses python 2.7 NDB for datastore. now i need to go through some dozens of entity kinds, and change a property value if the property exists (doesn't exist in all of them). i have some base-classes which the app normally uses, one with a pre-put-hook that sets certain values, but that MUST NOT happen for the migration.

at first, i thought i would use some batch tasks for each kind, that would query all entities, and if "badProp" in entity._properties, then change it, and put(). but the put() would again call the pre-put-hook

on the other hand, i can't just use a different base-class, or a generic model (e.g. polymodel), because i want to preserve the entity objects as they are (except of that property value)

Hi are there any issues on deploying to app engine?

maarten, not at all. every few months i experience some temporary issues with deploying, mostly that it tells me that the deployment succeeded, but i may not immediately see the new version live

hello, i need to install gsutil from google storage on a linux debian distribution (testing), the command tar xfz gsutil.tar.gz -C $HOME does not create a directory, i have python 2.7 installed, did i miss something ?

philophil_ this channel is about google app engine and the app engine sdk. I doubt you'd get anyone familiar with that tool here.

Trii, thanks for the information

Trii: how did he end up in here???

does that happen a lot

Anyone experienced with Blobstore API? I need a way to store images uploaded from my website and get URL for this image.

I am wondering if Blobstore API is what I should be looking at. I need a way to achieve this from Java Servlet and Google's page says this way of doing it is "deprecated"

Guest62071, that's what I've used but yeah, apparently it's deprecated
