[google-appengine] Re: Design consideration
Using a distance range with subsequent filter to return only 25 rows is a good idea. Even if I pass a distance range in request url say from=0.1 and to=0.9 still then one needs to write this "SELECT * FROM myTable" as I cannot use limit statement here If multiple iphone users are accessing the wsgi app in about same time, will GAE manage this? Or does there will occur any lock problems? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Babel has a helper to extract strings from Django templates (default in App Engine). I'm not sure how to integrate, but there are several tutorials out there (both are popular). If you're using webapp, though, I recommend you to take a look at Jinja2. It is very similar to Django's template but easier to extend (and it is more modular, faster, etc). Babel integration is also built in. There are some tutorials about using Jinja2 (with Django or webapp) in the cookbook: http://appengine-cookbook.appspot.com/ have fun :) -- rodrigo --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Problem with memcache.get_multi
Hi folks, I'm having a very curious problem with get_multi. I'm giving it a list of keys ten items long. It finds items 1 and 2 without issue, but doesn't find the last eight. If I reverse the search list and then use get_multi, I now get items 9 and 10, but not 8 through 1. If I make individual calls to memcache.get in a loop, I manage to get back all 10 items. ;) My code was working great before, and I've only been running in to this problem today. The only difference is that my memcache entries now hold a bunch more data than before -- which I suspect may be the issue? Though I'm not getting any errors when storing the items, and they can all be recovered individually. Any help? Thanks for your help!

[google-appengine] Re: I18N, translation
i18n depends on the webframework you are using, that is the easy stuff, there are plenty solutions for it out there, what Google provides is much lower lever and it its the difficult stuff like scalability. If you use django (e.g. with apppenginepatch), then i18n is built in works fine, at least with what I have tried so far. And if you wanna do some custom i18n solution I also recommend you to use babel.

[google-appengine] I18N, translation
Hi, I searched on this group looking for info on how to best build a google app that supports multiple languages. The results are disappointing: there is no recommended way to do this and it seems that many attempts from other developer are not fully functional. I read these threads: http://groups.google.com/group/google-appengine/browse_thread/thread/76d96246c91812a0 no solution http://groups.google.com/group/google-appengine/browse_thread/thread/e95549aea53f2dde paritlal solution: still can't switch language dynamically http://groups.google.com/group/google-appengine/browse_thread/thread/5c3104f821a8c829 no reply http://groups.google.com/group/google-appengine/browse_thread/thread/f2dc37b6cec1a21d no solution ... etc When I started to spend time learning Python and GAE, I assumed google was intenational enough so I do not have to worry about I18N support. It is frustrating for non-english customers to see so little support for i18n on products from companies as important as Google. What is gae's team official statement about support for localized application? Does GAE support it or not ? Are we supposed to develop our own localization solution? - Mel T. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Design consideration
You could filter out a square region of a reasonable distance from the iPhone in the query and then sort the positions in your application and finally remove positions from the bottom of the list if there are too many. Do keep in mind that you have to adjust the longitude range as you get closer to the poles, because one degree longitude close to the poles is much longer in distance than it is at the equator. I'm not sure how the datastore handles floating point filtering. It might be wiser to make integer fields with the positions multiplied by a factor. You'll also need to solve the "wrap-around" problem that occurs at 0/90 degrees.

[google-appengine] Design consideration
Hi all I have to design a wsgi app which is returning xml data to be consumed by an iphone application. The iphone app sends an http request with latitude and longitude from iphone. Based on these entries, I need to query datastore table. The datastore table itself also contains latitude and longitude values in each row. I need to apply a distance calculation formula on this based on latitude and longitude values. Then I need to sort them in ascending order of distance. My problem is that we cannot reach at the final result before completing the calculation and also I do not want to send large xml data to iphone application to consume. Earlier I think to divide the process in two phases Phase 1: Does the calculation in wsgi application and generates the entire xml and sent the same to iphone PHase 2: iphone app sort the xml into ascending order But it will result in performance issue both at iphone and wsig application end. So is there any alternative that may give us limited data and that too sorted so that iphone can ask for another slot with no performance issue --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Creating an app which could handle 100,000 users
Thanks guys, your replies have so far been really insightful. I totally agree with that Google App won't be able to handle that many requests at this stage (being free and all) but I haven't even started developing the app, so reaching a hundred thousand users is still far away, but what I would like to do is build a system, keeping in mind that I would have to serve that many users in the near future. So guys, how would you actually go about designing a system which has scalability built into it from day one.. I'm a total newbie here, so please excuse me if my questions are a bit general. I've heard that its essential in scalable systems to keep the server as stateless as possible, and not to keep to much data in the memory but rather store it in the database, so my question is, how do you do about making sure that your database doesn't end up being a bottleneck. Any other advices would be welcome and highly appreciated.

I had more logging calls than non-logging calls. I'm not sure what the problem was, but my code seemed to stop executing (I think when I tried to construct the User()) without even raising anything.

This is what everybody keeps telling me... I'm not familiar with Django yet. What is the "other code" that needs to reference DB users?

100,000 simultaneous users constantly sending 2 requests/minute to the server would add up to 288 million requests per day. The request quota is currently ~1.3 million requests per day, and this quota is not listed as being adjustable. If you really need to serve this many requests per day (which I believe would put you close to Yahoo and Google in pagerank), you might need to build your own multi-million dollar cloud.

[google-appengine] Re: Creating an app which could handle 100,000 users
Hali, yes it is possible to for AppEngine to handle 100,000 users with many concurrent requests. Of course your app will not be allowed to use such resources until they release the payment system to break out of the initial free resources. AppEngine is built with Scalability in mind (http://en.wikipedia.org/ wiki/Scalability) and will allow you to reach an inifinite capacity, given you provide an inifinite amount of funds (at competitive market price).

What exactly was the problem? Could you please post the settings backend code here? Did you try to add a few logging.info() calls into your backend in order to verify that the code gets executed, at all, and in order to check which line fails? > My Users don't persist in the DB (auth is done remotely), and I have > been warned this may cause problems for the admin site due to > messaging issues, but we don't use the admin site anyway.

It's probably better to have a proxy user in the DB or at least fake a user entry (not saved in DB) with a faked key_name, so other code can store ReferenceProperties to that fake user.

[google-appengine] Re: regain the ownership of my app
Hi, The easiest way to fix this, if there was more than 1 developer of the app, is to have the other developer invite you again to develop for the app. If this deleted account is the only one that was a developer, I will need to manually fix this. Please let me know off the group if this is the case. -Marzia On Thu, Jan 29, 2009 at 4:33 AM, zsombor wrote: > > hi! > > I messed up the ownership of my app (http://mikorjon.appspot.com/). > I created this app with my previous google account which was: > 'zsphone' > Recently I reorganized my e-mail addresses, and I deleted this gmail > address, and the account as well, and I created this new one: > 'zsombor42' > > Now I realized I cannot access my app, and I cannot figure out any > solution to access it. > > Does anybody have any idea how to solve this lame situation? :) > > thanks! > > Zsombor > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Debug with pdb + Django + app-engine-patch ?
Hi, I also tried to get debugging to work. In the comments for this article: http://jjinux.blogspot.com/2008/05/python-debugging-google-app-engine-apps.html Somebody describes how to define a method with which you can invoke the debugger in a way that should work with the dev_appserver. The same method is used in this discussion: http://groups.google.com/group/google-appengine/browse_thread/thread/9f226a46a0de3188 I didn't really test it, but it seemed to work when I tried. (even without commenting out "sys.meta_path = [hook]" like described in the discussion). You may also want to take a look at firepython in conjunction with the Python logging module, it can also be of great help when you want to verify how your code behaves in action.

[google-appengine] Uploading files using YUI uploader 2.6.0 and Google App Engine
I am using the Yui Uploader 2.6.0 advanced example and apparently it
is working fine on the client side.
Basically the uploadAll function in javascript passes to the uploader
the url containing the script to handle the uploaded file/s on the
server:
function upload() {
if (fileList != null) {
uploader.setSimUploadLimit(parseInt(document.getElementById
("simulUploads").value));
uploader.uploadAll("http://localhost:8080/sign2"; );
}
On the server side the requestHander object (self) does not contain
the variables Filename or Filedata (the default names to access the
name and data of the files respectively). In essence I have tried the
following but it does not retrieve anything, they are empty:
class ProcessOpinion2(webapp.RequestHandler):
def post(self):
f1 = self.request
f2 = self.request.get('Filedata')
f3 = self.request.get(u'Filedata')
arg = self.request.arguments() --> there is no arguments, arg is
empty
When I debug the app, self.request contains the file uploaded:
Content-Length: 1457
Content-Type: multipart/form-data; boundary=--
ae0Ij5Ij5Ef1KM7Ij5Ij5KM7ei4gL6
Host: localhost:8080
User-Agent: Adobe Flash Player 9
X-Flash-Version: 9,0,124,0
ae0Ij5Ij5Ef1KM7Ij5Ij5KM7ei4gL6
Content-Disposition: form-data; name="Filename"
Help.JPG
ae0Ij5Ij5Ef1KM7Ij5Ij5KM7ei4gL6
Content-Disposition: form-data; name="Filedata"; filename="Help.JPG"
Content-Type: application/octet-stream
but once it executes self.request.get('Filedata') then the
self.request is emptied:
Request: POST /sign2
Accept-Types: text/*
Connection: close
Content-Length: -1
Content-Type: multipart/form-data; boundary=--
Ij5GI3gL6gL6gL6KM7GI3KM7Ij5gL6
Host: localhost:8080
User-Agent: Adobe Flash Player 9
X-Flash-Version: 9,0,124,0
I have also observed that the upload data are contained in a **unicode
multidic** in self.request.POST but I do not know how to retrieve this
data or why they also disappears after executing self.request in the
script.
Thanks in advance,
--~--~-~--~~~---~--~~

[google-appengine] how to get the requester's TCP port
I know I can get the requester's IP address by self.request.remote_addr, but how do I get the requester's TCP port number? I tried self.request.remote_port, but that does not work. I also saw people using os.environ['REMOTE_ADDR'], so I was thinking of trying os.environ['REMOTE_PORT'], but it gives me an error saying "NameError: global name 'os' is not defined". Any idea what I are doing wrong? How do I define the global name 'os'?

[google-appengine] Creating an app which could handle 100,000 users

I want to develop an application which would need to cater for like 100,000 users using it simultaneously. All the users would be sending requests to the serve a couple of times a minute and this would put i think a huge load on the server. Would the Google App Engine be able to handle this?

[google-appengine] importing model definition (n00b question)
Hi, I'm a n00b to python and GAE, so apologies in advance for the naivety of this question.. My app has multiple .py files, which share db models. So to avoid repetition, I want a single file that has the db model definitions, such as 'datamodel.py'. I can then import that into my main.py with 'import datamodel'. To then use the model I need to do 'datamodel.modelName'. Is there a way to avoid the 'datamodel.' part, so that I can address it directly as 'modelName'? I suspect this has something todo with namespaces, but I dont really understand it. thanks, tom --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Assigning key_name for Expando object
thanks a lot Alex, In our application we need to create 200 entities in a single request,if we pass the key_name in constructor,Internally it makes a RPC call to the server every time which intern slows down my application, Because each RPC call takes nearly 10 millisecond(10*200 = 2 second). so we planned to maintain a local cache, and then to commit all entities in a single RPC call. If I use the above method for assigning the key_name, will it make a RPC call every time? if it makes a RPC call,then is there any way to assign a key_name to a created entity(not yet saved) with out making RPC call.
