[google-appengine] multi-tenant data model
Hi, I want to create a business application designed for multiple companies. When I design the data model for big table, I wonder if there is any best practice on multi-tenant data model. Shall I create several columns (user, organization) for each table(model), and return the data only belong to this particular user and organization? or shall I create model using polymodel and create a subclass for each company? when a company want to customize the data model, how should I do it? Option A: use expando to add dynamic column, maintain a list user defined columns in a separate meta data table. Option B: Use a text column to store a JSON for all additional columns user want. Any other better options? wei --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

hmm, __key__ IN ... works for me. from http://shell.appspot.com/ :
>>> class Foo(db.Expando):
pass
>>> foos = Foo.all().filter('x >', 0).fetch(3)
>>> keys = [f.key() for f in foos]
>>> keys
[datastore_types.Key.from_path('Foo', 32425L, _app=u'shell'),
datastore_types.Key.from_path('Foo', 33376L, _app=u'shell'),
datastore_types.Key.from_path('Foo', 33399L, _app=u'shell')]
>>> got = Foo.gql('where __key__ in :1', keys).fetch(3)
>>> [f.key() for f in got]
[datastore_types.Key.from_path('Foo', 32425L, _app=u'shell'),
datastore_types.Key.from_path('Foo', 33376L, _app=u'shell'),
datastore_types.Key.from_path('Foo', 33399L, _app=u'shell')]
out of curiosity, are you actually including those parentheses around :
1 in your GQL query?

[google-appengine] Which server errors are reflected in the Dashboard?
After the timeouts and 502 server errors today, I've been looking at the dashboard area "Errors" and the logs. Some (not all) of my own warnings made it into the logs, but the "Errors" area didn't reflect any of the turmoil. In the documentation (http://code.google.com/appengine/kb/ general.html#erroruris), it says: "If any error occurs when attempting to load a URI, our system records that error. We then show the URIs that record the most errors in the past 24 hrs in the admin console." What errors are not covered? I'd like to know so I don't get a false sense of security if nothing shows in logs or dashboard but my users are severely affected.

I've seen at least one Google team member in this forum saying that's the way it is and use string if you want it to be None. That doesn't prevent us, though, from starting an issue: http://code.google.com/p/googleappengine/issues/detail?id=1117 Star it if you'd like the default behavior to change. -Bill On Mar 2, 8:42 pm, Ian Lewis wrote: > Bill, > > Agreed. > > But if it's by design then is there a design that says so? like > documentation?

[google-appengine] Re: How do disable cache on urlfetch?
Turns out that this issue is in the issue tracker:
http://code.google.com/p/googleappengine/issues/detail?id=739
The answer is to make your request in the following manner:
result = urlfetch.fetch(url, headers = {'Cache-Control' : 'max-
age=300'})
Where "max-age" is the oldest you want data returned from the cache to
be.

You can add a random number after the url. For instance,

url=url+'?'+ random.random()
Good luck.

My app needs to get a fresh copy of a dynamic webpage page every few

[google-appengine] Re: Viewing a non default version log (appspot uri)
In the upper lefthand corner of the admin dashboard, where the logs and everything else live, it should have your app id and your currently selected app version. Logs are for the currently selected version only, so select the new version and then click on the logs. (For some reason, for me, the version resets to the default version whenever I upload anything, and I have to select the latest (debug) version again.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: What happened to minor version numbers?
Hey Dan,
Thanks for the quick response. I didn't realize the version number
could be an arbitrary string. That's great information, and resolves
my sense of being very limited. That would be great to see in the
official documentation. That said, the documentation is for the most
part, excellent -- concise and sufficient.
Thanks again!!

[google-appengine] Clarification of Term 4.4
4.4. You may not develop multiple Applications to simulate or act as a single Application or otherwise access the Service in a manner intended to avoid incurring fees. Clarification I am currently developing my app to operate on 1 application instance per company/organisation. These application instances can have content/xml messages that flows in/out between them. Is this considered to be in violation of the above terms ? This would also mean that a large number of organisations equates to a large number of applications. Is this also considered a violation when I manage multiple application instances thru' multiple gmail accounts since there is a 10 application limit ?

[google-appengine] How do disable cache on urlfetch?
My app needs to get a fresh copy of a dynamic webpage page every few
minutes. I am fetching date from a URL with this function:
def getUrlData(url):
result = urlfetch.fetch(url, headers = {'Cache-Control' : 'no-
cache', 'Pragma' : 'no-cache'})
if(result.status_code != 200):
logging.error( "Error getting URL data: %d" %
result.status_code)
return None
logging.warn("Fetch %s response headers: %s" % (url, repr
(result.headers)))
return result.content
However, it seems like I am still getting cached data. The logging
statement output the following:
Fetch [URL] response headers: {'Content-Length': '21883', 'X-Google-
Cache-Control': 'remote-cache-hit', 'Age': '633', 'Expires': 'Mon,

Hi Kariem, HTTPS is restricted to appspot.com domains, so it is not possible at this time to restrict login to Google Apps and serve HTTPS traffic. This is because you can only authenticate Google Apps users when serving off of that Google Apps domain. However, we are working a solution that will allow you to accept Google Apps logins on appspot domains, which should allow you to have both Google Apps login and secure traffic (serving off of appspot). However, we do not currently have a release date to announce for this feature. -Marzia On Sun, Mar 1, 2009 at 6:22 AM, Kariem wrote: > > This is a reply to the (already closed) thread at > > http://groups.google.com/group/google-appengine/browse_thread/thread/4c93c01f75ee3ce4 > > This problem still exists and somehow conflicts with the security > options described at > http://code.google.com/appengine/docs/python/tools/configuration.html#Secure_URLs > At least this is how I understood it. > > You have two exclusive options for a restricted/secure application > > a) Serve the application at myapp.example.com (with Google Apps) and > have it restricted to users from this domain during the registration > setup for this application. > > b) Serve the application from myapp.appspot.com and provide secure > connections via HTTPs. > > > Variations: you could use a (fragile) hybrid approach for applications > on (b) and check whether the user's email address has the same domain > you planned to restrict to. > > > I just want to verify what others think about that, or whether there > is ongoing discussion on this subject, or even a feature request or > defect that I haven't found with a primitive selection of search > terms. > > Thank you, > Kariem > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: what is the budget to use google app engine for one year?
Hi, With out knowing more information on they type of application you plan to build, even with only 500 users, it's difficult to do this estimation. For instance, if the app was low traffic, each person only using it once or twice a day, it's certainly possible you could run the application for very little or nothing with our free quotas: http://code.google.com/appengine/docs/quotas.html After that it depends mostly on what resources you expect to use (CPU intensive? Bandwidth intensive?). For instance, with CPU Intensive applications we've suggested that 80% of your daily budget go to CPU, 8% to Bandwidth out, 2% for bandwidth in, and 10% to stored data. So, spending $1/day would get you an additional 8 CPU hours, .66GB data out, .19 GB of data In, and 21 GB of storage over the free amount. You can choose any custom configuration for your budget, so it's possible to dial any of those numbers up or down based on need. -Marzia On Sat, Feb 28, 2009 at 5:13 PM, DiveIntoGAE wrote: > > Suppose i have a company that has 500 people, and i want to built a > website using google app engine for the people in my company, how can > i estimate the one year budget using google app engine?Can anybody > give the detailed process to work out the results?You can suppose some > datas when dealing with it. > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: What happened to minor version numbers?
Hi Bender -
Yes, that paragraph needs to be updated. A long time ago the Admin Console
displayed the number of times a given major version was uploaded as a
"minor" version number. (And that last sentence should read, "Only the
latest *minor* version is retained for each major version.")
As for integrating with source control, keep in mind that the version
identifier (the "major" version number) can be any string. I know
developers who have their build process automatically update app.yaml to use
the source control revision number as the version identifier for every
deployment. This technique requires manually switching the public
("default") version after each deployment and regularly cleaning up old
versions, but that may be worth doing anyway.

[google-appengine] Re: What happened to minor version numbers?
Hi -- I have a follow up to this question. In the GAE documentation (http://code.google.com/appengine/docs/python/ tools/configuration.html), it says: "On the Administration Console, the version number appears as a major version (version), and a minor version that corresponds to the number of times this major version has been uploaded. Only the latest major version is retained." Google may maintain minor version numbers internally somehow, but there don't appear to be any minor version numbers that are visible to GAE developers. If your e-mail is true, then the above quote is misleading. Additionally, if only major version numbers are available to developers, then that doesn't give us a lot to work with in terms of source control/tracking/maintenance. Thanks!!

[google-appengine] Re: LinkProperty and Null/None values.
Ian, This is by design and one of my peeves at the moment. A number of the datastore properties will throw an exception when given None values, so it makes them useless for storing optional properties. I think I ran into the same problem with LinkProperty and EmailProperty. The general solution is to just use a StringProperty. You could use a "None" marker like "http://nolink"; or "not specified" depending on validation of the property, but I find this less appealing. -Bill On Mar 2, 4:22 am, Ian Lewis wrote: > I have a model set up with a LinkProperty which is not required however when > trying to save the entity with a value of None I get a BadValue error saying > the Link cannot be empty.

[google-appengine] cost of running appengine_django
Does anyone have a rough estimate as to what it cost to run a site on appengine_django vs. running on the django 0.96 that comes with GAE? Perhaps you migrated your application one way or the other and could comment on what you saw? Higher CPU? Slower response times? Also: Does appengine_django run instead of django0.96 or does it run on top of it?

[google-appengine] Re: Deleting CounterShards
Ian, We're both in agreement. I was confused by what you meant by "count" and didn't realize you were talking about the count() method. Looking back, it's clear now how you meant fetch and count methods and my response could be misinterpreted if "count" meant count(). My first instinct now is to amortize expensive operations (counting, ranking, etc) on each put. The count() method should be avoided by using counters, which can either be implemented as an entity with integer property or shards, neither of which have any limitations. So I meant to say counting is not an issue and can be implemented much more easily than Bloog's current sharded counter, since no Bloogs will probably get more than one comment per second. The next version of Bloog will use an integer property in a single entity. -Bill On Mar 2, 12:47 am, Ian Lewis wrote: > Bill, > > The docs say otherwise. count() on a query object returns a maximum of > 1000.http://code.google.com/appengine/docs/python/datastore/queryclass.htm... > > Sharded counters are used to ease contention for highly updated objects but > that doesn't downplay the need for counters.

[google-appengine] scheduled maintenance
Hi GAE team, I'm writing to express frustration about the scheduled maintenances of March 2 and March 9. I'm using GAE to host several time-dependent games being played by tens of thousands of people. Having datastore writes unavailable for 30 minutes during the peak traffic time is frustrating and expensive. The cost to my small business will be significant. I acknowledge that with a globally distributed service every hour of the day is equally bad. I also acknowledge that downtime is a statistical inevitability. However I would like to believe that *scheduled* downtime is not inevitable. There must be a way for a company with Google's resources and talent to upgrade server hardware without taking the entire system offline for up to 30 minutes. As a customer who's investing considerably in this platform, I'd appreciate some insight into the mechanics of these "scheduled maintenance" decisions. How often can we expect these outages? If I were a provider of a social service based around baseball, for instance, what recourse would I have if Google decided to perform a scheduled maintenance during the seventh game of the World Series?

[google-appengine] Re: ImportError: No module named google
Terribly sorry to mention this, but you reminded me of this classic old joke: Patient: "Doctor, it hurts when I do this" (poking himself in the eyeball) Doctor: "Then don't do that." In your case, I'll recommend that you don't do that, and instead, do this: 1)start menu 2)cmd 3)C:\Program Files\Google\google_appengine\appcfg.py update path-to-- your-app.yaml The Google App Engine people tried to trick you into poking yourself in the eye, by making two different modules, each named appcfg.py. And they didn't make it clear in their documentation which file you should use. So don't feel too bad. and, while I'm giving you recommendations: 2) Download the latest version of the SDK; it will probably save you from hurting yourself a few more times.

[google-appengine] Re: App Engine vs Amazon S3
I've been using both for the last 8 months or so and they can work together Pricing for both services: S3 Pricing $0.150 per GB – first 50 TB / month of storage used $0.140 per GB – next 50 TB / month of storage used $0.100 per GB – all data transfer in $0.170 per GB – first 10 TB / month data transfer out $0.130 per GB – next 40 TB / month data transfer out $0.110 per GB – next 100 TB / month data transfer out $0.100 per GB – data transfer out / month over 150 TB App Engine Pricing $0.15 per GB of data stored by the application per month. $0.10 per GB bandwidth incoming, $0.12 per GB bandwidth outgoing. $0.10 per CPU core hour. This covers the actual CPU time an application uses to process a given request, as well as the CPU used for any Datastore usage. Amazon S3 cost = Storage + Data Transfer In + Data Transfer Out = 0.15 GB/Mo + 0.1 GB/Mo + 0.17GB/Mo App Engine cost = Storage + Data Transfer In + Data Transfer Out + CPU used for storing and serving = 0.15 GB/Mo + 0.1 GB/Mo + 0.12GB/Mo + 0.1 CPU/h So there is not a simple formula for calculating how much you'll gonna spend using each service... Why choose s3? -You can use some apps like browsers for browsing the files you have there. -You could connect it to the Amazon CloudFront and have your content on the Edge... -if you need to protect your files, this is already implemented in s3 (signed URL with expiration time) -304 Not modified already implemented... Why choose GAE? -you can use the image API -creating a protection code for your files isn't hard and you could have a more sophisticated schema (one time use URL?) My guess: GAE is cheaper i've been using S3 because of the (now old) 500MB limit in storage that GAE had... Hope this helps!

[google-appengine] Viewing a non default version log (appspot uri)
Preliminaries: my deployment script gets svn version number (via svn info), sets the version in app.yml and does the upload via appcfg.py I increase version number to be able to test the app before going live using the uri in the admin dashboard.

If the problem persists, please report your problem and mention this error message and the query that caused it. " where can I see the stack trace? I've tried already to call webapp.WSGIApplication with debug=true. Still nothing in the logs.

[google-appengine] Re: Deleting CounterShards
Bill, The docs say otherwise. count() on a query object returns a maximum of 1000. http://code.google.com/appengine/docs/python/datastore/queryclass.html#Query_count Sharded counters are used to ease contention for highly updated objects but that doesn't downplay the need for counters. You need to either put a counter on a separate entity or create sharded counter if you want to count more than 1000 entities.

[google-appengine] Re: Deleting CounterShards
You can count well over 1000 objects -- the limitation is in the fetching, but that's not the reason for sharded counters in Bloog. I wrote Bloog way back when App Engine was new and I was trying out different "best practices" for datastore ops. Sharded counters are a way to handle heavily-used counters, e.g. if the counter was getting updated dozens of times per second. If you have that many increments/ decrements on a counter, if you put the counter in a single integer property, you'd start getting write contention. In retrospect, doing the sharded counter in Bloog was complete overkill. It was useful to me at the time, because I was learning. But the next version of Bloog will likely use a single integer property for the counter and scrap the sharded counter. -Bill On Mar 1, 9:11 pm, Ian Lewis wrote: > Krishna, > > The datastore can only return or count up to 1000 objects so if you have > more than 1000 objects in the database you cannot count them without a > counter.
