It would be nice to have some documented way to express that fact, to make it so that A.get(key).b_set throws an exception. I don't know why it would be an error or why you want to throw an exception, but the b_set attribute is just a query. You can always create your own query function that does whatever it is you want. Maybe something like the following: class A(db.Model): def get_b_set(self): if self.cant_refer_back_to_b: raise Exception return self.b_set_private class B(db.Model): a = db.ReferenceProperty(A, collection_name = b_set_private) Ross Ridge --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

This is causing me a issue, as i cant update two separate entity groups in one transaction. unless im missing something i dont want to group them as the Thing may be sold at a later data to a new User. so i need to: 1)get the users money 2)if they have enough create the Thing and put it in the datastore 3)update the users money and reference the Thing to the user somehow and re-store If any of this fails i need it all to roll back. Currently im creating the Thing regardles and performing a transaction on the User, if this fails i delete the Thing after.

[google-appengine] Re: Shutdown deployed application?
I don't think you can as a first-order operation. But, you could easily upload a version of your app that is shut down (possibly with nice, simple, static messages to that effect). If you upload it under a different version string (change version: in app.yaml), then you'd be able to shut down the app by switching the version in the Versions section of the dashboard. Of course, anyone who can guess your other version string could still access the old app, so this isn't as complete as an actual app-logic level change.

[google-appengine] Re: Reference collection fetching
If you put your own __init__ in your model classes, you can count how many times instances are created. You can then watch the count to figure out where/when those model classes are created. Since successful datastore queries create instances of model classes # watch A._counter class A(db.Model): _counter = 0 def __init__(self, *args, **kwds): A._counter += 1 super(A, self).__init__(*args, **kwds) On Oct 11, 10:55 am, Jeff Nichols [EMAIL PROTECTED] wrote: Answering my own question here... father = Father.all().filter(name =, John).get() father.name = Doe sons = father.son_set.fetch(1000) print sons[0].father.name #prints 'John' Maybe I'm just used to more 'traditional' ORM systems, but that seems to me unintuitive. Not too mention inefficient. Since Google is so concerned with performance, you'd think they would have built-in some sort of level 1 cache for entities. Oh well... And I'd still like to be able to have a datastore access log.

On a side note, I could figure this out myself if there were some way to log datastore access. Have I looked over some way to enabled this sort of logging?

[google-appengine] Re: db.ReferenceProperty - need some mechanism for disabling collection
It's an error in the sense that I know that any code that tries to use certain back links, a.b_set in this example, is wrong according to what I know about my schema. Since I don't define b_set in A if I want back links, I'd really rather not say that I don't want b_set in A if I don't want it, especially if the way I say it looks a lot like a definition of b_set. I suppose that I could make my own version of db.Reference property that create a random name for unwanted backlinks.

It would be nice to have some documented way to express that fact, to make it so that A.get(key).b_set throws an exception. I don't know why it would be an error or why you want to throw an exception, but the b_set attribute is just a query. You can always create your own query function that does whatever it is you want. Maybe something like the following: class A(db.Model): def get_b_set(self): if self.cant_refer_back_to_b: raise Exception return self.b_set_private class B(db.Model): a = db.ReferenceProperty(A, collection_name = b_set_private) Ross Ridge --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

If that's all you want then just give it a name that, like in my example, says that it shouldn't be used. There's nothing you can do enforce your schema. If someone wants to find all the B's that refer to a given A, they can just create their own query.

[google-appengine] Re: a way to determine image size would be greatly appreciated
Thanks Jeff, that is indeed pretty much the same issue. I swear I searched for it, but it was late... Anyways, I'm loving the GAE with Django 1.0. I'm excited to see how it evolves. thanks, - Claude On Oct 10, 1:47 pm, Jeff S [EMAIL PROTECTED] wrote: Hi Claude, This sounds a bit like the following feature request:http://code.google.com/p/googleappengine/issues/detail?id=435but your idea may be slightly different.

Maybe it's not so easy, I don't really know.
