Using the google appengine datastore, is there a way to perform a gql query that specifies a WHERE clause on a StringProperty datatype that is case insensitive? I am not always sure what case the value will be in. The docs specify that the where is case sensitive for my values, is there a way to make this insensitive?

I would like to create a web IM chat system using Google App Engine using XMPP possibly.
It would allow users of a social network to talk with each other.
Is this possible using GAE?
I haven't used GAE before. Does anybody know of any good examples/code which I could look into to get started?

Hello,
I am after a Python module for Google App Engine that abstracts away limitations of the GQL.
Specifically I want to store big files (> 1MB) and retrieve all records for a model (> 1000). I have my own code that handles this at present but would prefer to build on existing work, if available.
Thanks

Hi,
I am able to properly pass a string variable to the gqlquery through parameter substitution, here's the code i've tried to use;
user_name = self.request.get('username') #retrieved from UI
p = models.UserDetails.all().filter('user_name = ', user_name).fetch(1)
I don't get any results and the query fails silently. But when I hard c...
I like to check if there is any result for my datastore query in the Google App Engine Datastore. This is my query:
users = User.all()
users.filter("hash =", current_user_hash)
What is the fastest and most elegant way to check if my query returns any result?
PS: I know a way to do so, but I'm very unsure if it is very efficient...

The Java documentation says that an app can perform a query during a transaction, but only if it includes an ancestor filter, but there is no documentation for how to do it. Can anyone provide some example code that shows how to do this in the most concise way possible?

I persist in storage an object with a child inside it. There is an "Owned One-to-One Relationships" (http://code.google.com/appengine/docs/java/datastore/relationships.html#Owned%5FOne%5Fto%5FOne%5FRelationships). Now I want to load objects but I have ONLY id of child's object. Is it possible?

My app.yaml wants to do this:
handlers:
- url: /process/(.*)
script: process.py \1
So that I can pass an argument to the process.py script.
This was working in the SDK, but oes not seem to be possible in the production servers, possibly because they are looking for a file to execute "process.py arg" which does not exist.

Hi everybody,
I am actually implementing a web application on Google App Engine. This has taken me for the moment a huge time in re-designing the database and the application through GAE requirements and best practices.
My problem is this: How can I be sure that GAE is fault tolerant, or at what degree is it fault tolerant? I didn't ...
I would like to test appengine. At this moment it is not clear to me if there are libraries that support custom authentication. I want the user to be able to create an account on the site without having to have a google (or any other) account.
Does that kind of libraries exists or do you have to write it from scratch?
Can anyone prov...
I'm new to google appengine and java webprogramming (jsp/servlets/frameworks) (not to webprogramming or java). I was wondering if appengine supported java frameworks and, if so, which of them are recomandable? Are there any frameworks that support authentication?

Coming from a java background I'm used to having a bunch of properties files I can swap round at runtime dependent on what server I'm running on e.g. dev/production.
Is there a method in python to do similar, specifically on Google's App Engine framework?
At the minute I have them defined in .py files, obviously I'd like a better separ...
I read an article of an indie game developer who is using Google AppEngine to cache his main site and blog, to protect provide high-availability during traffic spikes (Digg, Slashdot effect).

I see a similar question in Problems while saving a pre-persisted object in Google App Engine (Java), and indeed I was not calling close() on my persistence manager. However, I am now calling close, but my object update is not being persisted. Specifically, I want to remove an element from a Set, and save that smaller set. Here is the...
