Re: [google-appengine] export to csv
Hi Wesley, I think I didn't express well My Application it's written with GAE/J . Our customer ask us to give him a way to export to csv the entities of his application. So, I Googled a lot, and I found the only way to do that it's deploying a "parallel" python application. I follow these links http://appengine-cookbook.appspot.com/recipe/using-the-python-bulk-exporter-tool-with-a-java-application/ http://code.google.com/appengine/docs/python/tools/uploadingdata.html#Downloading_and_Uploading_All_Data http://groups.google.com/group/google-appengine/browse_thread/thread/e26ea1dd8b9a38f9 My question is: It's possible to export to csv without writing a python class for each Java class ?

[google-appengine] App engine - RPX Openid/ User Auth / Session Management - HELP!
Ive spent days searching the web and im drawing a blank. I simply want
to integrate RPX (janrain) into Appengine - lods of code for the
script inserts and the return of the openid token - thats all great -
but other than that no-one seems to take it any further as in actually
create an openid login that works - why? i assume no session
management?
Here is a simple class handler that gets the TOKEN for the open id and
then makes a fetch to grab the users profile. All very simple using
RPX.
class RPXHandler(webapp.RequestHandler):
def get(self):
token = self.request.get('token')
url = 'https://rpxnow.com/api/v2/auth_info'
args = {
'format': 'json',
'apiKey': '#YOUR KEY#',
'token': token
}
r = urlfetch.fetch(url=url,
payload=urllib.urlencode(args),
method=urlfetch.POST,
headers={'Content-Type':'application/x-www-form-
urlencoded'}
)
json = simplejson.loads(r.content)
logging.info(json)
if json['stat'] == 'ok':
unique_identifier = json['profile']['identifier']
nickname = json['profile']['preferredUsername']
email = json['profile']['email']
# log the user in using the unique_identifier
# this should your cookies or session you already have
implemented
self.redirect('static/loggedin.html')
else:
self.redirect('static/error.html')
Now # here is where the problem starts - ideally we could be lazy and
just log them into Google accounts - but their is no method to log a
user in ie;
user.login(email)
so that abandons any hope of using google accounts - and to fair if we
have open id - why bother!
SO...
Next easy route - sessions - but in webapp appengine their are none -
Can anyone HAS anyone made this work - need some method of protecting
each page - ie Login=true
A method to log out
A method to get user credentials
Basically a simple user system using RPX/Openid - Dont need register
or passwords - just a user system that auths through RPX/Openid and
stored the data on app engine etc
I hope this make sense?

[google-appengine] Re: export to csv
I recommend using the new bulkloader we're working on. I'll send you a link to it--it should make your life pretty simple. You do not need to deploy a Python app (see various threads from me-- we'll document this soon). bulkloader --dump writes out a sqlite3 file with encoded entities-- it's not particularly useful by itself, it's primarily useful for bulkloader --restore. Though it can be parsed. --Matthew On Jan 27, 5:19 am, Pablo Francavilla wrote: > Hi Wesley, I think I didn't express well > > My Application it's written with GAE/J .

[google-appengine] Re: App engine - RPX Openid/ User Auth / Session Management - HELP!
Hi Martin,
I'm working on something similar at the moment. It is a bit difficult
to find information; the best reference I have found so far is the
DemandID application(http://demand.openid.net/). You can get the
source for it from the SVN server (http://demand.googlecode.com/svn/
trunk). This application uses its own simple session implementation,
but you could replace it with something like GAE Utiltities.
Hope this helps.

[google-appengine] Getting JUnit tests running for Eclipse and JDO
I have gotten the basic setup recommended in the docs. I am able to
query the database successfully but as soon as I attempt to persists a
JDO object I get a can't find annotations error. The code is simply:
public class UserTestCase extends LocalDatastoreTestCase {
public void testDatesBeingSetOnCreate() {
User user = new User("w...@thebunkers.com", "mypassword");
//DatastoreServiceFactory.getDatastoreService().put(user);
PersistenceManager manager = newPersistenceManager();
manager.makePersistent(user);
manager.close();
Query query = new Query(User.class.getSimpleName());
assertEquals(1, DatastoreServiceFactory.getDatastoreService
().prepare(query).countEntities());
}
}
The error occurs at the makePersistent call. If I comment it out the
test runs fine except of course there is no user on the assert line.
The error is:
org.datanucleus.jdo.exceptions.NoPersistenceInformationException: The
class "The class "com.sootra.shared.User" is required to be
persistable yet no Meta-Data/Annotations can be found for this class.
Please check that the Meta-Data/annotations is defined in a valid file
location." is required to be persistable yet no Meta-Data can be found
for this class. Please check that the Meta-Data is defined in a valid
file location for JDO.
I am able to run the create user fine when running the app locally, as
well as uploading it to app engine. So the code is fine, but I am
unable to get JUnit test to recognize where the MetaData is being
created by the enhancer.
Has anyone successfully gotten this to run in Eclipse. I am guessing
that I am missing some classpath setting or meta information, but can
not find any references anywhere on the net yet.

Splitting an application across multiple systems leaves your application with a downtime which is the sum of the downtimes of the individual systems. I wouldn't like to do that. I would hope Google would lift the file limit so we could get the extra speed within the same system.

[google-appengine] question about memcache time
I am building a social network site, which involves a lot of activities by users. I am using memcache to keep track of "who is online". Whenever a user access my site, I store some user information (name, etc.) to memcache using the user id as the memcache key. By making the memcache timer short (a few minutes), I am able to quickly detect a particular user is on-line or not. In order to fully optimize this algorithm, I would like to know if the memcache timer (started as the result of previous memcache.set) will be reset when I call memcache.get or not. If memcache.get does reset the timer, I will simply call memcache.get each time the user accesses the site, and do nothing if it succeeds (and call memcache.set if it fails). If it does not, I need to call memcache.set whenever the user access the site (to explicitly reset the timer). I'd appreciate your help.

Re: [google-appengine] question about memcache time
Hi Satoshi, The memcache timers do not get reset when you get() a value, so you'll have to do as you suggested and set() the timer each time the user accesses your site.

Re: [google-appengine] Re: PHISHING APP retwite
I've seen quite a few posts from people in different countries complaining that *some* ghs IP addresses are blocked, and they often use their hosts files to hit one that isn't.

Re: [google-appengine] Re: Lock the memcache and how to block the call ?
I'm still not entirely clear on what you're trying to do. Why do you need to sync these requests? If it's a queue of some sort, would the TaskQueue API help? http://code.google.com/appengine/docs/python/taskqueue/ 2010/1/28 Iap > 2010/1/27 Danny Tuppeny : > > What is it you're trying to do?

Can you use SS.get(keys) instead? I think the reason that get_by_id requires the parent is because IDs are not full keys (and presumably an ID can be duplicated for different kinds). If you create Keys for them (you'll need to know their Kind), you could call SS.get(keys) and get them all in one go. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Ancestor Queries...
I've got a snippet of code that looks something like this
public getSubEntities(Transaction transaction, Key parent) {
com.google.appengine.api.datastore.Query query;
com.google.appengine.api.datastore.PreparedQuery pquery;
Map out = new HashMap();
query = new
com.google.appengine.api.datastore.Query().setAncestor(parent);
pquery = datastore.prepare(transaction, query);
for (Entity e : pquery.asQueryResultIterable()) {
out.put(e.getKey(), e);
}
return out;
}
...but when I run it, it never finds any sub entities of the given key. I'm
guessing I'm missing somthing? I'm trying to find all the direct
sub-entities of the given entity key. I've checked that they're in the
datastore, but for whatever reason the loop never hits. Any suggestions? I
haven't tried this in the app engine, just the local data store.
