[appengine-java] Re: Relationships
You cannot establish an owned relationship between two objects after the
child object (User in this case) has already been persisted. This is because
the parent key is embedded inside the child key, and keys can't be modified
once an entity is persisted in the datastore. You can, however, use an
unowned relationship and just store a reference to the User entity's Key. I
think this is what you're looking to do, since unowned relationships can be
established after the entities have already been stored.

How would you model this scenario then? Both models I discussed in my

JDO supports syntax like article.status but App Engine's datastore doesn't
support joins so you'll have to make article an embedded object in order to
use the query as you have it below:

Also, how have you defined reviewerParam? Is it a Key object or are you
actually passing in the Reviewer object? The latter won't work, but I'll
follow up about the former (querying on a Key).

find all articles reviewed by A and B
HashSetString tags;
int status; // derived from all Reviews' statuses.

Now I should be able to do reviewers.contains(A.key) and

Of course you can. JDO spec defines JDOQL, using Java syntax.
query.setFilter(reviewer == reviewerParam status == statusParam
article.tags == tagParam article.status = articleStatusParam);
What is tagParam ? an element of the hashSet?
You can't do Collection == element in Java so you can't in JDOQL.
You could do article.tags.contains(tagParam)

This is really good news. I would really have been sorry to move away from such a great platform. I enjoyed learning python through my GAE development effort.

(Assume that each handler file defines main() so it will be cached.) Is there any difference between these two approachs wrt reuse or other implementation issues? If your handlers are mostly distinct - that is, they have large codebases that they don't share in common with each other - using separate app.yaml handlers can reduce initial startup time by only loading the modules the particular request handler requires. If, like most apps, your handlers need to load most of the app in order to serve a request, however, this effect is minimal. For example, if an instance is created for one handler, will it be used for another? (The documentation says that handler files can be cached like any other module, but doesn't say how that interacts with instance reuse.) The same Python runtime environment can be used by multiple handlers - in which case they will share the same loaded modules. -Nick Johnson Thanks, -andy On Aug 26, 4:31 am, Nick Johnson (Google) nick.john...@google.com wrote: Hi PubliusX, On Tue, Aug 25, 2009 at 8:38 PM, PubliusX arjun.va...@gmail.com wrote: Hey, thanks.. but I figured out the problem.

[google-appengine] Supercharging your free AppEngine quota
Hi all, I've got a post (http://izuzak.wordpress.com/2009/08/27/how-to- supercharge-your-free-appengine-quota/) on pumping up your free AppEngine quota. Here's the useful payload: Other than billable quotas, there are also unbillable quotas which increase when you switch to the paid model but are not billed. So, by switching to the paid model, irregardless to how you distribute your budget, your app gets a free bump in the: * number of requests it can process from 1,300,000 to 43,000,000 and from 7,400 to 30,000 req/min, * number of outgoing HTTP requests from 657,000 to 46,000,000 and from 3,000 to 32,000 req/min, * number of memcache calls from8,600,000to 96,000,000 and from 48,000 to 108,000 calls/min, and many others. These are very usable improvements by themselves for apps that need to process a lot of requests (or bursts of requests) which don’t consume a lot of CPU time, or apps that need to make a lot of outgoing HTTP requests that don’t consume a lot of bandwidth. So here’s the idea for supercharging your free AppEngine quotas: 1) switch you app to the paid model by enabling billing, 2) enter the minimum daily budget ($1), 3) distribute the budget over resources you are 100% sure will not consume their free quota (e.g. if you have a stateless app which doesn’t use the database, put the whole $1 in the stored data quota). Since you put your budget on resources which won’t consume the entire free quota and since AppEngine doesn’t charge you anything if the app doesn’t step over the free quota – you are essentially getting a better free quota. What do you guys think? Are there any other hacks for squeezing more out of AppEngine?

What does your app.yaml look like? In particular, are you making these html files static? If so, your program can't access them to use them as templates.

Hello, Over the past few days i was trying to deploy my application making changes to the static files. I was not able to get the changes in the deployed version. The files i was referring are htm files which i have placed in the build path where normally classes would be present. for example, parent/src/main/resources/htm/*.htm parent/src/main/java/*.java Is there any problem?

[google-appengine] How can you access App.yaml data?
Is it possible to access the data in your app.yaml file from your app? (Not the file, but is the data loaded into the code anywhere). For example, I am looking to access the handlers with the login property set to required so that I do not have to repeat some sort of variable in the code because this is inconvenient to maintain. I need to force someone to actually register with the site once signed in with a google account but login:required would still let them view the page without registering so I need to access the urls. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] ClientLogin and prompt for username/password
Hi there, I need to use the GData API to add a post to a blog. Always the same blog, always the same user (whose credentials I happen to have, since they are my own). I've gotten this working, except for one thing: when I request the page that does this and the logic runs, I am prompted for my Google credentials anyways. Since I don't want the user of my app to be bothered with this (I am guessing it doesn't matter WHO authenticates, as long as someone does), I'd like to figure out how to stop this behaviour... The code that does the logging in is this: # Authenticate using ClientLogin. service = gdata.service.GDataService(email, password) service.source = 'GAE App' service.service = 'blogger' service.server = 'www.blogger.com' gdata.alt.appengine.run_on_appengine(service, store_tokens=False, single_user_mode=True) service.ProgrammaticLogin() Has anyone run into this problem?

Ok, I emailed you. Thanks On Aug 25, 7:43 pm, Jeff S (Google) j...@google.com wrote: Hi O, I've reset the index count quota and error out the indexes which were stuck in the building state. It does look like you have quite a few indexes, how many do you anticipate needing? It is usually no problem to increase the number of index for an app, though there is an upper limit which no one has hit yet to my knowledge. I'm curious if there is a way to reduce the number of indexes for your app or possibly restructure a few queries to remove the need for some of these indexes. The reason I advocate reducing indexes in general is that they can make writes to the datastore more expensive when a large number of indexes are involved.

this, but I can't think of anyway around it. I tried to manually
recreate the entity thru the Dashboard, with the same ID (112052) but
that doesnt work as the ID is randomly generated and cannot be edited.
Anyone have any ideas?

Or do you need to programmatically do this? If so, how do you achieve that? Jaap On Thu, Aug 27, 2009 at 1:47 PM, Nick Johnson (Google) nick.john...@google.com wrote: On Wed, Aug 26, 2009 at 6:39 PM, Andy Freeman ana...@earthlink.netwrote: Is there any reason to prefer multiple app.yaml entries over few? That is, one can match /pages/.*, /users/.*, /tasks/.*, /foo/.*, etc with separate app.yaml entries, followed by a catch-all app.yaml entry, each with its own handler file, each file with its own wsgi application, or with a single app.yaml entry (/.*) and a handler file with a wsgi application that has a clause for each of those cases. (Assume that each handler file defines main() so it will be cached.) Is there any difference between these two approachs wrt reuse or other implementation issues? If your handlers are mostly distinct - that is, they have large codebases that they don't share in common with each other - using separate app.yaml handlers can reduce initial startup time by only loading the modules the particular request handler requires. If, like most apps, your handlers need to load most of the app in order to serve a request, however, this effect is minimal. For example, if an instance is created for one handler, will it be used for another? (The documentation says that handler files can be cached like any other module, but doesn't say how that interacts with instance reuse.) The same Python runtime environment can be used by multiple handlers - in which case they will share the same loaded modules. -Nick Johnson Thanks, -andy On Aug 26, 4:31 am, Nick Johnson (Google) nick.john...@google.com wrote: Hi PubliusX, On Tue, Aug 25, 2009 at 8:38 PM, PubliusX arjun.va...@gmail.com wrote: Hey, thanks.. but I figured out the problem.

At least thats what I think.. because I reduced the number by removing an arbitrary 5-6 classes and its back to the old time. That's definitely not the case. App Engine doesn't even know how many RequestHandlers you're using, or even check what framework you're using. You were probably just getting a new instance on each request. -Nick Johnson -- Nick Johnson, Developer Programs Engineer, App Engine -- Nick Johnson, Developer Programs Engineer, App Engine --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Need help understanding an error (not sure if it is my fault or not)
Unfortunately the Datastore gives sometimes timeout exceptions on operations. You can catch them and take some action, like retry the operation. Or let the user know in a friendly manner. There has been a post of a retry decorator on 25-aug-2009. When you are wrapping your put() and get() operations in try-except wrappers for Timeout exceptions, also do it for the CapabilityDisabled exception in case the Datastore is in read-only mode during maintenance. 2009/8/27 Nevin Freeman nevin.free...@gmail.com: I am getting the following traceback: Traceback (most recent call last): File /base/python_lib/versions/1/google/appengine/ext/webapp/ __init__.py, line 507, in __call__ handler.get(*groups) File /base/data/home/apps/riabizdev/1.335829215948087052/ handlers.py, line 197, in get banner_code = models.Banner.get_by_id(int (banner_id)).get_code_and_log_impression() File /base/data/home/apps/riabizdev/1.335829215948087052/ models.py, line 209, in get_code_and_log_impression self.put() File /base/python_lib/versions/1/google/appengine/ext/db/ __init__.py, line 725, in put return datastore.Put(self._entity) File /base/python_lib/versions/1/google/appengine/api/ datastore.py, line 166, in Put raise _ToDatastoreError(err) File /base/python_lib/versions/1/google/appengine/api/ datastore.py, line 2100, in _ToDatastoreError raise errors[err.application_error](err.error_detail) Timeout And the method in question from models.py is this: def get_text(self): self.counter += 1 self.put() #this is line 209, where the error originates return self.text Is this a common problem that I can do something to avoid?

I can't write a query to find all the objects with this reference
property since I deleted one object which caused this problem.
That object is now gone.
That being said, I don't know if your method will work since all my
object right now are technically OK but since 1 is missing in the
list, it isn't generating it. Does that make sense?
