[google-appengine] Re: about sharded counter
You need to reach the incremental method on the db object from a
webapp.RequestHandler. From the source
http://google-app-engine-samples.googlecode.com/svn/trunk/sharded-counters/main.py
the counter-main-class is defined as:
import generalcounter
import simplecounter
class CounterHandler(webapp.RequestHandler):
Handles displaying the values of the counters
and requests to increment either counter.
def get(self):
template_values = {
'simpletotal': simplecounter.get_count(),
'generaltotal': generalcounter.get_count('FOO')
}
template_file = os.path.join(os.path.dirname(__file__),
'counter.html')
self.response.out.write(template.render(template_file,
template_values))
def post(self):
counter = self.request.get('counter')
if counter == 'simple':
simplecounter.increment()
else:
generalcounter.increment('FOO')
self.redirect(/)
So just make a post like the example eg. the simple counter:
form action= method=post
pinput type=hidden name=counter value=simple //p
pinput type=submit value=Increment Simple //p
/form
And rewrite your class to your purpose by following the counter-
example. If it to any help this i the source
http://google-app-engine-samples.googlecode.com/svn/trunk/sharded-counters/simplecounter.py
Did that make sence? :)

Hi guys,
I am new to gae and knew count() only return the exact num only when
the num is less than 1000
and I read the article about sharded counter
here:http://code.google.com/intl/en/appengine/articles/sharding_counters.html.
so I start to use it in my own project
like this:
import counter
class MyModel(db.Model):
name = db.StringProperty()
#overwrite put so when new one is saved, counter + 1
def put(self):
def txn():
counter.increment('MyModel')
return super(Mymodel, self).put()
return db.run_in_transaction(txn)
howerver, when I test this code, get a error BadRequestError: Nested
transactions are not supported.
I know why. howerver, i can not figure out how to go through it
beacuse i want save a entity and increase counter in a transaction
any ideas?
Thanks in advance

[google-appengine] Re: Neat URLs for developing multiple applications on same development machine
This is an alternative: VirtualHost *:80 ServerName myapp1 RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/$1 [P,L] /VirtualHost VirtualHost *:80 ServerName myapp2 RewriteEngine On RewriteRule ^/(.*) http://localhost:8081/$1 [P,L] /VirtualHost Also works with Google Secure Data Connector (SDC) to use alternative ports on local services instead of only port 80 or 443. /Emil Kjer On May 14, 12:58 pm, kRON filip.dupano...@gmail.com wrote: Thanks, that worked like a charm!

[google-appengine] Re: google apps how to make a test url...
You can manage your app engine apps via. the dashboard for google apps for your domain. I think it requires you to be an admin of the domain but you can give it a shot at: https://www.google.com/a/cpanel/REPLACE WITH YOUR DOMAIN/Dashboard Or, if you is added as an developer of the project you can visit http://appengine.google.com/a/REPLACE WITH YOUR DOMAIN /Emil Kjer On May 14, 8:31 pm, Aaron shyhockey...@gmail.com wrote: I know that but the company had a previous programmer that made the site. He made some app that will test the site it's for testing purposes. For example the url would be dev.mydomain.com that would be the url where I can go to and check out how the site looks and test the functions of it. It will be live but it's not the offical version just for testing purposes then I would upload it to the app that will use the url:www.mydomain.com Currently the previous programmer dosen't remeber what that app name was. So I am woundering if their is any way I can recover that app name? I mean I know the url. I thought if I send a e-mail to google asking if they can look it up .

[google-appengine] How to send authentication requests like u...@password through secure data connector?
I have been creating my own transporter to reach other ports than the
common HTTP ports in XMLRPC calls through google Secure Data
Connector. It is working fine, but i need to send user authentication
with my requests like u...@password: . Do anyone know how to do that?
My transporter is:
import xmlrpclib
import logging
from google.appengine.api import urlfetch
class MyTransport(xmlrpclib.Transport):
#overriding this method is enougth
#to put the 'user_intranet' header
def request(self, host, handler, request_body, verbose=0):
result = None
url = 'http://%s%s' % (host, handler)
try:
response = urlfetch.fetch(url,
payload=request_body,
method=urlfetch.POST,
headers={'use_intranet':'yes'},
follow_redirects=True)
except:
msg = 'Failed to fetch %s' % url
logging.error(msg)
raise xmlrpclib.ProtocolError(host + handler, 500, msg,
{})
if response.status_code != 200:
logging.error('%s returned status code %s' %
(url, response.status_code))
raise xmlrpclib.ProtocolError(host + handler,
response.status_code,
,
response.headers)
else:
result = self.__parse_response(response.content)
return result
def send_user_agent(self, connection):
connection.putheader(User-Agent, self.user_agent)
connection.putheader(use_intranet, yes)
def __parse_response(self, response_body):
p, u = xmlrpclib.getparser(use_datetime=False)
p.feed(response_body)
return u.close()
