In GAE, is there a way to find out if a User is an administrator? While the is_current_user_admin() reveals whether the current user is an administrator, I'd like to know if there's a way to discover if a given User object is for an administrator or not (e.g. a hypothetical User.is_admin() function). Thank you for reading. Brian ...

Each of my users is polling the server every few seconds. I need to keep a list of the users that have polled in the last 30 seconds handy for a task I have queued to run every few seconds. The obvious way I see to do it is to update a datastore entry every time the user polls, and query the entries that have a timestamp within the las...
One of the tips for lowering your app's cold-start latency is to use/upload as few JARs as possible. I'm wondering what can I do to prevent 3rd-party GWT libraries (like gwtquery.jar etc.) from being uploaded to GAE? (Once the app gets compiled these become useless, so it would be quite unfortunate should they attribute to the latency.) ...

I'm just staring off with GAE. So like many I'm used to standard SQL. Typically when you want to select data that has a certain field value you use: SELECT <columns> FROM <table> WHERE <column> = <wanted value> Is the correct way to do this in GAE <Model Class>.all().filter('<column> =', <wanted value>) Or is there a more efficien...
