[google-appengine] Re: Application Identifiers

[David Wilson]

Hey Sri,

For whatever strange reason, App IDs that conflict with Gmail
usernames are reserved by default. That means if
legendofthefiveri...@gmail.com is somebody's e-mail address, you can't
use it for your appspot domain.

[Paul Roy]

maybe im not getting the whole story here, but arent you evaluating  
your property against a string ?

im not a 100% on this but id think youd get different results from  
using < on a string than an integer value. that is if you can even  
make it pass the property's validation..??..

[google-appengine] Getting Data Using Key vs. Key_Name

[ecognium]

Hello Everyone,
It looks like Model.get(keys) raises an exception (BadKeyError)
when the key does not exist even though it is not mentioned here
http://code.google.com/appengine/docs/python/datastore/modelclass.html#Model_get.

On the other hand, Model.get_key_by_name(names) just returns None for
the keys that do not exist. If I understand it correctly keys and
key_names are not the same - i.e., i cannot use a key value inside the
get_by_key_name() call.. so how can i get data using key without
having to worry about determining which specific key was not valid?

I can create my own key names but I would like to use the default
uniqueness guarantee of the keys. If there is no easy way to deal with
this exception, is there an easy way to make the key_name same as the
key value provided by default?

In case you are wondering why the keys will be invalid: I am allowing
the users to bookmark certain objects.. so i store the key names in
the user prefs data... If the object referenced gets deleted then the
key information stored inside the userprefs will be outdated and when
they query for their bookmarks, it causes an issue.. I wanted to avoid
the whole process of going through every single user who may be using
the deleted key and remove  it real-time. so i thought i will just
handle it as a batch job...

Thanks!

Use app-engine-patch. It is much more complete and feature-rich and in
more active development. I might be biased, though... :)

[google-appengine] Re: Application Identifiers

[Sri]

Hi Dave,

   Thanks for that mate.  But yeah that still is a bit inconvinient
given that most gmail users may not even be app developers.

Also is it possible to show which of the cases the violation is off?
I mean whether if it is an existing gmail ID or an already registered
app.  Or perhaps a way to atleast talk to the gmail user to get some
kind of "Transfer" of the app name...

Also by tying app names to gmail user names, doesnt it incentivize
spammers to create fake accounts just to prevent a name from being
used for an app?

cheers

[google-appengine] Re: Application Identifiers

[Nick Johnson (Google)]

Hi Sri,

There's no way to see why an App ID is taken, unfortunately. As far as
'transferring' a username goes, any user can register an app with the
same name as their gmail account, so if you can convince the owner of
the account to register the app with the same name as their address,
and then add you as an administrator, you can remove their
administrator privileges and take control of the app (with their
permission, of course!)

People could create gmail accounts just to prevent a name being used
in App Engine, but it's not clear to me why they'd want to do that.

[google-appengine] Re: Getting Data Using Key vs. Key_Name

[Nick Johnson (Google)]

Hi ecognium,

Model.get does not return BadKeyError when attempting to fetch an
entity that does not exist - it returns None, as documented.
BadKeyError is raised when the key itself is invalid, because it lacks
a name or id, or has an invalid name. You probably want to check that
you're not generating invalid keys - such as one with a name that
starts with a digit.

How many results are you fetching, how big are the entities, and does
it _always_ time out, or just frequently? Does fetching a smaller
number of results cause it to time out less?

In an un-indexed list, the maximum number of elements is limited only
by the maximum entity size (1MB) and the time it takes to decode the
entity. The latter can be substantial in the case of very large lists.

Hi S K,

You can access the contents of a Google Docs spreadsheet using the
Google Spreadsheets API. Documentation is available here:
http://code.google.com/apis/spreadsheets/overview.html

In addition, you'll need to incorporate a session management system
like Beaker, or issue your own cookies, to keep track of a user once
they're authenticated.

[google-appengine] Re: Upgrade to 1.2.2, can no longer read files with csv.reader

[Nick Johnson (Google)]

Hi obvious,

The dev_appserver will deny you access to files that are 'skipped'
(that is, they will not be uploaded to App Engine), or static files.
Is that the case for the CSV file you are trying to open?

If the file is skipped, you can override the check by passing
--allow_skipped_files to the dev_appserver.

You can set a version in your app.yaml

I'm not sure what you mean by this.  Are you saying if I know enough
to reconstruct the full key name of an instance I want to retrieve I
can instantiate the model with that key name and then start using it
directly?  In other words, I know that when I create these instances I
use "some_string" + "owner model name" + "something else" as the key
name, so if I'm in some other situation where I know all those values
I can easily rebuild the key name and start using the model without
having to run a query on the datastore?

What is a "filter" in this context?  Is this a Java thing?  I've been

That's correct, as long as you also know the entity type and any
ancestors' keys.

It was user error - me.   I had deployed the feeling lucky app.
http://code.google.com/p/feeling-lucky-pictures/  I saw that it was
storing using the PersistenceManager in the code.   I did not notice
that it only used mem cache to retrieve the data.   I checked using
admin and the data is indeed there.

Thanks taking the time to help me.

[google-appengine] JDOObjectNotFound exception when using getObjectById

[vijay]

Hi All,
I am stuck with a very weird case here while using getObjectById() function,

I have a persistent class called Category and i am saving it to appengine
datastore using JDO.
I have tried to fetch a particular entry using query and getObjectById()
method, the query is passing and returning me the correct results but
getObjectById is throwing exception JDOObjectNotFound.

The Category class have a primary key field called id, a parent key and a
child key. the child and parent are actually primary key of other Category
instances.( I am trying to buuld a heirarchy of similar objects here. I am
using unowned one to many relationship here.)


// In following code we get the Id of parent and remove the child's
information from it.
Long id = e.getParent(); // returns parent Id.

Query query = pm.newQuery(Category.class);
query.setFilter("id == cat_id"); // get the Category with primary key id =
cat_id.
query.declareParameters("Long cat_id");
List results = (List) query.execute(id); // get parent
category. results contain the expected information.
if (results.iterator().hasNext()) {
   for (Category e3 : results) {
  Set child = e3.getChildrens(); // get the childrens.
   }
  }

Category e2 = (Category) pm.getObjectById(id); // throws JDOObjectNotFound
exception. It is expected to contain the same information as in results 1st
element.
e2.removeChildren(e.getId());
pm.deletePersistent(e);


As you must have seen in the code i am fetching same id using the query and
it returning me the expected objects while
the getObjectById is throwing the exception JDOObjectNotFound. Any clues why
it is throwing that exception.

I tried to google it but could not find any obvious reason,
Can somebody help me figuring out where I am doing it wrong.

Regards,
Vijay

[google-appengine] Re: What's the difference among key, id, and key name?

[djidjadji]

If you ask this type of question you obviously are not the writer of
the application.
Or have not read the code.
Do a search for "key_" on the code and all will be clear.

The application works fine on localhost. This problem only shows up
after deploy. It looks like the API version of the production
environment had not been upgraded yet. It's a really weird situation
and I can't figure out how to fix it.

Suggestions are welcome. Thanks!

[newbie]

i m using the following code to upload data.

this works fine...but now i need a id to prevent data replication i
want the id to comprise of 'Symbol'+Series+'date'  what changes do i
need to make to my code?

in the bulkupload i was using

 def GenerateKey(self, i, values):

b=str(values[0])
c=str(values[10])
d=str(values[1])
c=a+b+d+c
return c

[google-appengine] Details on Google's Partner Program?

[Beepboop]

Hi guys,

Does anyone have details on becoming a preferred partner to Google?
Most companies have a published partner program (along with the
criteria they use to evaluate partners) but, I haven't found one for
Google.  I'm specifically looking for the following:
- What are the tiers of partners and their respective benefits (e.g.
joint sales planning)
- Are there any costs or investments I need to make to achieve a
certain tier
- Aside from the Application Gallery, what are other ways Google will
monetize partner applications?

I just saw the Appirio webinar and was inspired to work closer with
Google.  Thanks!

[google-appengine] google apps how to make a test url...

[shappy]

Hi, I am going to start making a website for a company.

currently I want to know how I can make urls for google apps engine.

when I upload my app to google how would I know the urls that will be
part of the application? do I have to specifiy it with google app
engine sdk  or is it online managment panel?

the reason i as is because I need to make a  url like  www.domain.com
and one like   dev.www.domain.com

one url is for testing purposes and the other is the live url of the
website.

Also is their any way I can search the app id  of a url ?

cause I worked on  a website that I just made modifications. A
previous programmer made the base of the site and he setup the
website. He told me about an app that would upload it to something
it:  dev.domain.com

the problem is that he forgot the applications name. so I am finishing
up that site and soon I will need to know that app name.

Is their any way I can search for the app name if I have the url that
app name points to?

[google-appengine] Re: The next Google Earth?

[shappy]

How are you communicating with them?  you got to e-mail the admin.

on top of it I doubt google needs others to give ideas. I mean they
have staff that does it for them.


Also what else could you really do with google earth?  I mean they do
have live weather on it .

are you thinking to have them map cars? or something like that where
you can see airplanes flying in the sky lively.

they already do have airplane tracker where you see a 3d model of the
aircraft and it gives you  a yellow line showing your flight path.


I would think they should at least  factor in day to day traffic on
the roads. This could be helpful to take the quickest route during
rush hour.

I mean that would be kinda neat. I remeber I got directions with
google maps and also google earth and it gave me a route that had
heavy traffic which took longer to get to the destination  then if I
took the longer router which had less traffic.

You should find the ad...@google.com  email address and the  e-mail
them.  Usually they may not even respond to you if they think your not
a company or a buisness in any way. You have to be someone that is
known somewhat.

this is just  my input. Good Luck !!!  let google take your Idea :)

[google-appengine] Cost of large inserts

[GNS]

I need to make a very large insert (1 billion rows).

I'm currently using amazon SDB, and they use some odd formula for
price calculation, which will result in a cost of several thousand
dollars for this insert. Keep in mind that I have just one column
which will be around 50 bytes. So overall it's just 50GB of data. I
can to this in a few hours with a local computer, but amazon claims it
takes something like 15.000 machine hours and would cost a fortune.

Has anyone experience with the google app database? How do they
charge? How much does it cost to perform a very large sequential
insert?

Thanks

[google-appengine] Re: SMS Verification Help Form Broken

[David]

Hi,

I cannot succeed in using the sms issue form, even if I remove all the
newline characters from my comment... I always have "There were
errors: Comments"

I have my phone number associated with personnalitenumeri...@gmail.com
(my company account) but I want it now associated with
david.fauth...@gmail.com (my personal account).
With Google App Engine, I cannot create applications with my personnal
account because it needs SMS verification, already done with my
company account with my personal number.

Is it possible to re-associate my phone number (+3362096...) with my
personal account (david.fauth...@gmail.com) ? Or should I destroy my
company account (personnalitenumeri...@gmail.com) ?

Thanks a lot

[google-appengine] Re: Customizing "sender" name when sending out emails

[oliverox]

I am currently building a picture sharing system on appengine. I would
like any user (not signed in with google) to be able to share pictures
with their friends by sending a customized email to them. I want the
sender name to display something more user-friendly such as the
senders name even if the "from" email address is ad...@mydomain.com.
Can I expect google to allow this feature? if not, may i know the
reasons behind not allowing this?

Thank you.

[google-appengine] Google Partner Program tiers and benefits?

[Beepboop]

Hi, does anyone know if Google has a published (or unpublished)
Partner Tier Program?  For example, Salesforce has a 3 tiered program
if you're an ISV...Basic, Select, and Premium. Each tier comes with
specific benefits and I'd like to understand if Google has a similar
program and what criteria they use to evaluate partners.  Thanks!

[google-appengine] Adding a child to detached parent

[GravidNode]

Using the JDO persistence, I'd prefer to work with detached objects so
that I don't have to spew and chew DTOs all over the codebase.  I did
some searching for "detached," but found no topics.   I've set the PMF
property for detachAllOnCommit(true).  A simple JUnit test blows up
with the following sequence:

1.  Parent p = new Parent();
2.  pm.makePersistent(p) ;   // Inside a transaction
3.  Child c = new Child();
4.  p.add(c);
5.  pm.makePersistent(p);   // Inside separate transaction

(It works if you omit step 2, but children will be added a after the
parent has been persisted, steps 3-5 could happen days later)

javax.jdo.JDOFatalUserException: Illegal argument
NestedThrowables:
java.lang.IllegalArgumentException: can't operate on multiple entity
groups in a single transaction. found both Element {
  type: "Parent"
  id: 91
}
 and Element {
  type: "Child"
  id: 92
}


I understand the multiple entity group limit within a single
transaction, but why are they in separate groups?
It's as if c is persisted without knowledge that it is p's child,
despite being found by traversing the persistent
one-to-many field in the parent.  It's handled correctly if both
parent and child transition from transient to persistent
together.

Reading the docs, I assume I could force the seeding the Entity Group
Parent ID component in c.id with either
1. Child c = new Child(p); or inside
2. p.add(c);

but then my objects are no longer POJOs, they're tightly coupled to
datastore, and I'd have to call out to persistence/transaction layer
in my child constructor (not a good idiom) or in my parent collection
mutator (needlessly chatty to the back end).  Am I missing something
basic here?  It seems like I should be able to do this.

Any help would be appreciated.
Also, kudos to whoever wrote the code that tossed the IAE, it's a very
clear error message.

[google-appengine] Neat URLs for developing multiple applications on same development machine

[kRON]

Dear all,

I was wondering if someone could point me in the right direction for
creating neat aliases for each application to avoid the URL clashes
and clutter in my browser.

Ideally, I'd like something like http://myapp1/.$ to bind to localhost:
8080 and http://myapp2/.$ to localhost:8081. I have Windows 7 RC1 and
Apache 2.2. I've created entries in my hosts file for myapp1 and
myapp2 to point to 127.0.0.1 and created VirtualHost entries, but the
problem is that I'm either left with redirecting or rewriting the URL
which, in the end, doesn't mask me from seeing http://localhost:8081.

Sorry if this isn't the right place to ask, but I'd appreciate any
pinpoints!

[google-appengine] Cron Trouble

[d43m0n]

The short story:
  It doesn't work!

The long story:

>From dashboard : /cron/report - daily mail report - every day 16:30
(UTC) - Hasn't run yet

app.yaml
...
handlers:
- url: /cron/report
  script: cron_report.py
  login: admin
...

cron.yaml
cron:
- description: daily mail report
  url: /cron/report
  schedule: every day 16:30

The webapp's authentication is configured to work with users from a
certain google apps domain. The cron_report.py script was tested on
live version and works perfectly when called by the url, but as the
dashboard says it hasn't run yet. It was first created 4 days ago, and
last updated 2 days ago (the webapp, not the cron job itself, but the
job shows up in admin logs).

Can anyone help ?

[google-appengine] screwed up setting up app runtime....

So I just got the account activated and created a couple of entries

the runtime but I just want the java version ...

Is there anyway to fix this ? Or did I just loose those two names
forever ? Is it possible to change the runtime ? (I know delete is not
allowed).

[google-appengine] Cron Trouble

The short story:
  It doesn't work!

The long story:

>From dashboard :
/cron/report - daily mail report - every day 16:30 (UTC) - Hasn't run
yet

The cron job was created and uploaded 3 days ago. Last update (though
I didn't really change anything about the cron job, just shows up on
admin logs) was 1 day ago.

app.yaml
...
- url: /cron/report
  script: cron_report.py
  login: admin
...

cron.yaml
cron:
- description: daily mail report
  url: /cron/report
  schedule: every day 16:30

The webapp's authentication is configured to only work with users from
a certain Google Apps domain. The cron script (cron_report.py) works
perfectly, and has been tested on live version by simply accessing the
url, but as the dashboard says, it hasn't run yet.

Can anyone help ?

[google-appengine] Re: Invalid runtime specified

[Nick Johnson (Google)]

Hi samurai,

You can continue to develop your app on the local development server
while you wait for your invitation to the Java preview.

In any case, you should get your invite shortly.

[google-appengine] Re: Getting Data Using Key vs. Key_Name

[ecognium]

Thanks, Nick. You are right. I ran into some issues, which i tracked
it down to the key call but then I ended up  testing the keys using
values  '123' etc... So the BadKeyError is from my bad key request and
not unavailable key.

[google-appengine] use of Django's "forms.Form" on GAE

[nwalt...@sprynet.com]

I'm trying to create a form that is not based on a model.

I'm getting sample code from this page:
http://docs.djangoproject.com/en/dev/topics/forms/

# This code causes nasty error:
# Tried index in module views. Error was: 'module' object has no
attribute 'Form'
class Provision(forms.Form):
   somefield = forms.EmailField(required=False)

Here are my imports:

import os
import datetime

from google.appengine.api import users

from google.appengine.ext import db
from google.appengine.ext.db import djangoforms

import django
from django import http
from django import shortcuts
from django import forms

I'm getting the idea that with GoogleAppEngine, I have to substitute
some other class for forms.Form?   If so, what is the correct class or
technique?

Thanks,
Neal Walters

[google-appengine] Re: use of Django's "forms.Form" on GAE

[Neal]

I seemed to solved that problem by changing one import:

from django import newforms as forms

Now I'm trying to get a field from the form:

TaskLog1.taskCode = form.cleaned_data['taskCode'];

which is giving this error: #ProvisionForm' object has no attribute
'cleaned_data'
(the form was defined as follows:
 form = ProvisionForm(data=request.POST or None)

and like this:

class ProvisionForm(forms.Form):
   buttonFlag = forms.CharField(required=False)
   taskCode   = forms.CharField(required=False)

So again, it looks like the Django samples that I'm trying to follow
need more modifications to work with GAE?
What is the substitute for the "cleaned_data" method?  Or where can I
look it up?
How can I get the value from a field on my form into a database
variable?

Thanks,
Neal Walters

[google-appengine] Re: Datastore usage ~ 80 times more than expected (Add your vote to a datastore usage accounting feature)

[Jason (Google)]

Hi Andy. In this case, the list of Key objects will be smaller than the list
of key strings. Even though the picked db.Key object is larger, it is a
binary-encoded protocol buffer form that gets stored, which is smaller than
the pickled string. That said, I doubt it would make a tremendous difference
unless you have a lot of these entities or these lists have a lot of values.

[google-appengine] Re: Datastore usage ~ 80 times more than expected (Add your vote to a datastore usage accounting feature)

[Jason (Google)]

Hi Philip. Calling to_xml() is not a great indicator of the size of your
entity as stored in BigTable. Unfortunately, there is currently no
straightforward way to estimate how large your entities are, although we're
working on possible solutions to this problem.

Without knowing your data model or index definitions, it's certainly not
impossible to rule out the size of your indexes, particularly if your
application is querying across mutliple multi-valued properties, although
this isn't the only scenario that could lead to huge indexes. If you have a
property that you're never querying against, I recommend you try removing
this single property index and see if that makes a noticeable impact or see
if you can eliminate any of your custom indexes which you don't use too
often.

You can't set the runtime at the application level; each version will
have whatever runtime was set the last time you uploaded.

If you're seeing an Invalid Runtime message, it's because you're not
approved for the Java version yet (it's still in limited preview).

[google-appengine] Re: use of Django's "forms.Form" on GAE

[Neal]

I think my issue is that taskCode is being returned as a "None".

This is my objective. I want a form with two buttons on it.  When a
user clicks one button, I want to store a row in BigTable that shows
that "Task01" started at at the current date/time.  When he clicks the
second button, I want to update the completed time in that same row
with the current date/time.

Right now, I'm just working on the first button.  My idea was to set
the value of the which button they clicked in a hidden field.

Text1={{ form.text1 }}






I've alternatively tried defining my form like this:



{{ form.taskCode }}



but with this second method, the field is not hidden, it shows up in a
text box in front of the button.


Since I needed some way to debug and see the values, I wrote this code
in my views.py:

  text1 = "debug_info:"
  for key in TaskLog1.__dict__:
try:
  if TaskLog1.__dict__[key] != None:
 text1 = text1 + "\n" + key + "=" + TaskLog1.__dict__[key]
  else:
 text1 = text1 + "\n" + key + "=None"
except:  #avoid errors when we hit an object such
as "User"
   pass;

  form2 = ProvisionForm(initial={'text1': text1});
  return respond(request, user, 'provision', {'form': form2,
'TaskLog': TaskLog, 'text1': text1})


This allows me to pass "text1" back to the form to see what the value
are, and taskCode is always = None.

Any ideas how to get the value of which button was clicked?  I might
eventually have 100 such buttons, each with a different taskCode value
assigned.

I've also tried setting the taskcode this way:
  form = ProvisionForm(initial={'taskCode': "mytest"})


Also, is there a smarter way to debug than what I did above?

Thanks,
Neal Walters

[google-appengine] Re: Cost of large inserts

[Barry Hunter]

It al depends on how long you want to to take. leaving it running long
enough means you could almost do within the free quota.

http://code.google.com/appengine/docs/quotas.html
http://code.google.com/appengine/docs/billing.html

Probably the only quota that you can't get round and would have to pay
is monthly storage. (you only get 1Gb free)

I would like to have it the sooner the better.

I see free daily limit is 10 million requests, but since it's 1
billion rows I can't wait 3 months for it to complete.

Has anyone experience of inserting way more than 10m in a day and is
able to tell me what the cost would be?

[google-appengine] Re: Application Identifiers

[Sri]

Hi Nick,

Asking an email-user to transfer an app name would work if email-
users were that savvy (ok gmail users are a bit more techier than non-
gmail users, but still asking them to log into appspot is a bit of a
stretch dont you think?)..

why would people register email accounts similar to popular app
names?  remember what happened with domain squatting?

When you create a new application, you have to specify the application
id (in online magamenent panel). This is a unique id, through which
your application is identified amongst all other applications build on
AppEngine. Your appspot URL will be
.aspppspot.com.

For development purposes, the SDK provides a local web server. It will
be on your machine. The production will be .appspot.com. For
creating urls like http://domain.com and http://www.domain.com, you
need to do appropriate mapping in the Dashboard of your website's
cpanel. If it has been bought from google via google apps its easy.
refer http://code.google.com/appengine/kb/general.html#naked_domain

You can look into the cpanel domain forwarding and masking, if there
is any entry for .appspot.com or if it has been purchased
through Google Apps, then look under the appengine services tab.

Neal,
IIRC, cleaned_data is available only after you have used is_valid()
method? Did you missed it out ?

[google-appengine] Re: Datastore usage ~ 80 times more than expected (Add your vote to a datastore usage accounting feature)

[WeatherPhilip]

Jason

I removed a bunch of single property indexes (by setting indexed=False
and then loaded and stored each item. This didn't save much (a few
percent). Also, the fact that I can't see the single property indexes
makes it more tricky to figure out if they have really gone or not!

I'm now deleting 10% of the records, but I've only reclaimed 2-3% of
the space (0.92GB down to 0.90GB).

I don't have any significant use of multi-value fields (there is one
field, but only rarely does it have more than one (2) values).

[google-appengine] Random 500 Internal Server Errors

[WeatherPhilip]

I get some small number of Internal Server Errors during the day --
but it appears that the request never actually started. The time/cpu
information from the logfile says:

500 10243ms 0cpu_ms 0kb

Given that there is never a 0 cpu_ms request if my code actually runs,
I suspect that the infrastructure was trying to start a new instance
of my app, and failed after 10 seconds.

Is there anything that can be done about this?

Thanks

Philip

[google-appengine] Re: Datastore usage ~ 80 times more than expected (Add your vote to a datastore usage accounting feature)

[Andy Freeman]

Argh!

This means that one form (db.Key) is smaller than the other
(comparable string) for the datastore while the reverse is true for
memcache.

How about defining a __getstate__ and __setstate__ for db.Key that is
smaller than the string equivalent?  This will help for memcaching any
db.Model instance whose .key() is defined.

Argh!

This means that one form (db.Key) is smaller than the other
(comparable string) for the datastore while the reverse is true for
memcache.

I've created am issue ( 
http://code.google.com/p/googleappengine/issues/detail?id=1538
)requesting a __getstate__ and __setstate__ for db.Key that is smaller
than the string equivalent.  In addition to eliminating the
inconsistency betwen the datastore and memcache sizes, it will reduce
the size of every memcache'd db.Model instance whose .key() is
defined.
