actually, we do have limits on those: 1000 keys per batch get and 500
entities/keys per batch put/delete.

without getting too much into cron itself, yes, any app engine code
that uses the datastore will generally be subject to these per-
operation limits.

this is true. by "30 queries per request," i'm guessing robin actually
meant 30 subqueries per query. this happens with the IN and !=
operators, which are implemented in pure python, in user land, by
running multiple subqueries and merging the results. these kinds of
queries are limited to at most 30 subqueries. this is mentioned in the
"Note" on 
http://code.google.com/appengine/docs/python/datastore/gqlreference.html
.

we're planning to publish a more comprehensive document with all of
these limits soon. thanks for the nudge!

cw,

What's the directory where models.py with your Quiz model in it? More
accurately what is the python module with your Quiz model in it?

[google-appengine] Re: The API call datastore_v3.Delete() required more quota than is

[Ian Lewis]

You likely need to wait a day or so to have the quotas reset themselves. It
looks like you using too much of one of the appengine quotas.

[google-appengine] date range in query

[arnie]

For a datastore table with two db.DateTimeProperty columns start_date
and end_date, i need to use a date range in query but below given
query is not working
current_date=datetime.datetime.strptime(self.request.get
('current_date'), '%Y-%m-%dT%H:%M:%S')

db.GqlQuery('SELECT * FROM myTable where start_date>=:cdate and
end_date<=:cdate',cdate=current_date)
in the parameters I am passing current_date=2009-01-10T00:00:00
Should we not compare dates this way?
But this is not working

gql as below works.
SELECT * FROM Image where added > DATETIME(2009,1,1,0,0,0) and added <
DATETIME(2009,2,1,0,0,0)
we must use the integer form (the manual lists b0rked forms)

[google-appengine] Re: ReferenceListProperty

[mcobrien]

Hi, I'm not sure if it's what you're looking for, but parent-child
relationships are best modeled by using a property on the child
entity, which adds a new property to the parent.

So for:

class Company:
   pass

class Employee:
   name = db.StringProperty()
   company = db.ReferenceProperty(Company,
collection_name="employees")

... instances of Company will have an "employees" property which will
result in a query for all Employee instances the reference the
company.

The article below has some great details on creating entity
relationships:
http://code.google.com/appengine/articles/modeling.html

thanks

[google-appengine] Dynamic list in django form for a pull-down menu

[Brian]

I've been trying to figure this out for hours across a couple of days,
and can not get it to work. I've been everywhere. I'll continue trying
to figure it out, but was hoping for a quicker solution. I'm using App
Engine datastore + Django.

Using a query in a view and custom forms, I was able to get a list to
the form but then I was not able to post. I have been trying to figure
out how to dynamically add the choices as part of the Django form...
I've tried various ways with no success. Help!

Below are the two models and my form. In InfoForm, I’d like to display
a list of address_id from the Locations db for the current user. By
the way, I realize I need to use some other sort of property for
address_id, and have tried several recommendations, but have not been
able to figure out the right approach yet.

class Info(db.Model):
user = db.UserProperty()
address_id = db.StringProperty()
info = db.StringProperty()
created = db.DateTimeProperty(auto_now_add=True)
modified = db.DateTimeProperty(auto_now=True)

class Locations(db.Model):
user = db.UserProperty()
address_id = db.StringProperty()
address = db.StringProperty()

class InfoForm(djangoforms.ModelForm):
address_id = forms.ChoiceField()
info = forms.ChoiceField(choices=INFO_CHOICES)  class Meta:
model = Info
exclude = ['user','created','modified']

Example of data in Locations:
user = t...@example.com
address_id = home
address = 999 washington st, somecity, CA

user = t...@example.com
address_id = work
address = 123 lincoln st, somecity, CA

So, if t...@example.com is logged in, I’d like to display home and
work in the address_id (pull-down menu) field of InfoForm.

Thanks

[google-appengine] inequality filters on two different properties

[Rick]

I'm confused. If this statement (GQL query is not allowed, because it
uses inequality filters on two different properties in the same query)
holds then how am I to do a Calendar type app and query the DataStore
for all events that occur within a 30 day window?  Isn't that
something like:

Select * from Calendar where beginDate >= beginofDateRange and endDate
<= endofDateRange

How could I do that? How does Google Calendar do that?

Thanks,
Rick

[google-appengine] Re: Problem with models & Google App Engine Helper for Django

[Matt Brown]

Hi Carlin,

As I believe Ian was hinting at in his response, the helper (and Django)
expect your models to be within a Django application (basically a
subfolder) of your Django project (your Django project == your App
Engine application, confusing I know ;p).

So you need to create a directory, say called "myapp" and place your
models.py in that (don't forget to also add __init__.py). Then you list
"myapp" in the INSTALLED_APPS section of settings.py and you should be
good to go.

[google-appengine] Re: Problem with models & Google App Engine Helper for Django

I give it a whirl tonight and see if that works. I've seen a couple examples
that did that but didn't understand it was required.

Thank you both. :) GAE/Django/Python is pretty exciting but there isn't tons
of sample code/books/etc out there yet so the help is really appreciated.

Take care,

[google-appengine] Re: memcache.add => RuntimeError: maximum recursion depth exceeded

[Chris Tan]

If you have deeply nested data, you can work around it by:
1. flattening your data
2. using a patched pickle module which does not have the recursion
limit:
http://gist.github.com/22217

To be honest, I don't see why the above code would be causing this.
If you still have problems with this, it may be a good idea to post
the source for the entire module.

as you've written it, this query is probably more expressive than you
need it to be. if you s/endDate/beginDate/, ie compare beginDate to
*both* of the range endpoints, you'll be able to run it. if you
absolutely need to query for events that occur entirely within the
endpoints, you could do the same query and post-process the results by
filtering out entities with endDate > endofDateRange in memory. if you
don't want to post-process, though, you're right, you can't do this
exact query entirely within the datastore.

> How could I do that? How does Google Calendar do that?

google calendar doesn't run on app engine, so it's not subject to the
same limitations as app engine. i'd also reiterate that while the app
engine datastore is based on bigtable, they're still very different
beasts. the datastore provides many additional (and different)
features, guarantees, and capabilities, including the query planner
and API. details in 
http://sites.google.com/site/io/under-the-covers-of-the-google-app-engine-datastore

[google-appengine] Re: python problems - HTTPSHandler

[Alexander Artemenko]

I have found, that if you are working with macports, than you need to
install py25-socket-ssl module:

sudo port install py25-socket-ssl

I suggest, if you are working on the "debian like" linux, then you
should try something like that first:

apt-cache search python ssl

Or, as a last resort, make sudo easy_install ssl (i should download
and install ssl module from the http://pypi.python.org/pypi/ssl/)

[google-appengine] UnicodeEncodeError and Django templates

[Scott]

Hello,

I'm seeing the following message when trying to render a template
using Unicode characters:

UnicodeDecodeError at /index.html
'ascii' codec can't decode byte 0xe3 in position 0: ordinal not in
range(128)

I have both these settings using Unicode:

DEFAULT_CHARSET = 'utf-8'
FILE_CHARSET = 'utf-8'

As well as the meta in the header:



Finally, I have verified that the django.po files are properly encoded
as UTF-8 (they don't make it through the 'compilemessages' command if
they are not).

I'm not sure how Django is getting the idea that it should use an
ASCII codec, any ideas how I could get these templates rendering
correctly would be greatly appreciated.

[google-appengine] manually validate an ASCID ticket

[Jason C]

We use Google Accounts for our application, which is a Django(trunk) /
app-engine-helper application.

Normally, on our views, we can just use

  @require_login

decorator, and everything works out.

However, in some cases, we are not able to pass the cookie that makes
this stuff work out well.

Is there a mechanism that we can use the ASCID ticket value and
validate that it is a valid login?

Imagine that we pass thie ASCID value as a request param and hit an
undecorated view like this:

  def my_view(request, ascid):
auth.validate_ticket(ascid) # does some programmatic call like
this exist

Is there some way to programmatically validate the auth token for a
Google Account?

Aside: this is coming up because of a bug in Flash where the cookies
are not propagated when it posts back and so the auth fails.

[google-appengine] Re: Problem with models & Google App Engine Helper for Django

[Ian Lewis]

Yup,

The appengine_django/models.py has a funny little piece of code that
requires your models module to not be a top level module.

class ModelOptions(object):
  ...
  def __init__(self, cls):
self.object_name = cls.__name__
self.module_name = self.object_name.lower()
model_module = sys.modules[cls.__module__]
self.app_label = model_module.__name__.split('.')[-2]
self.abstract = False

The fourth line of __init__ there breaks if you have a modules with models
in a top level module. Go figure.

Why pay for something you can have for free? :-)

If you have exhausted the allocation of applications for your account,
possibly (like so many, it seems) by creating a bunch of test
applications, then you can follow this trick to get rid of them:

 * Create a new account.
 * Invite the new account to be developer for each application you want to shed.
 * Confirm all the invitations for the new account.
 * Log in as the new account, and remove your 'real' account from the
developer list for each application.
 * Log out, log back using your real account. Observe applications are
gone, and you can create more.

I think this trick is semi-officially sanctioned, so I doubt you'll
get kicked off the service for doing it (at least during the preview
period :).

[google-appengine] Inconsistency between dev_server and production server on sharded counter behaviour.

[Qian Qiao]

Hi,

Following the article on sharded counter, I decided to extended it a
bit to add a function that returns the current count and increments
the counter.

Here's the function:

def get_count_and_increment(name):
  config = GeneralCounterShardConfig.get_or_insert(name, name=name)
  def txn():
total = memcache.get(name)
if total is None:
  total = 0
  for i in range(1, config.num_shards):
counter = GeneralCounterShard.get_by_key_name(name + str(i))
if counter is not None:
  total += counter.count
  memcache.add(name, str(total), 60)

index = random.randint(0, config.num_shards - 1)
shard_name = name + str(index)
counter = GeneralCounterShard.get_by_key_name(shard_name)
if counter is None:
  counter = GeneralCounterShard(key_name=shard_name, name=name)
counter.count += 1
counter.put()
memcache.incr(name)
return total

  return db.run_in_transaction(txn)

It works fine on the dev_server but on the production servers it
throws the following error:
BadRequestError: can't operate on multiple entity groups in a single
transaction.

Can anyone give me a pointer?

Thanks

Hrm. I can say at least that you don't need a new phone number when
inviting a Google Apps account to develop. I have no idea about the
non-apps workflow.

 Hi Carlin,

 As I believe Ian was hinting at in his response, the helper (and Django)
 expect your models to be within a Django application (basically a
 subfolder) of your Django project (your Django project == your App
 Engine application, confusing I know ;p).

 So you need to create a directory, say called "myapp" and place your
 models.py in that (don't forget to also add __init__.py). Then you list
 "myapp" in the INSTALLED_APPS section of settings.py and you should be
 good to go.

 Cheers

[google-appengine] Proper way to handle DownloadError: ApplicationError: 5

[MajorProgamming]

Is this the proper way to handle Download Errors from urlfetch (which
happen quite often in my app)?

try:
  result = urlfetch.fetch(url=url)
except DownloadError:
  #return an error


Basically a coding/python question

Also, would it work to except, and try again within that same test?

For example,

except DownloadError:
  result = urlfetch.fetch(url=url)

[google-appengine] Re: code project svn initialization

[thebrianschott]

The error message has stopped, so maybe the system needed more time to
process my initial requests. I still got the same error message asking
me the following.

> (R)eject, accept (t)emporarily or accept (p)ermanently?

So I replied "p" and got some more positive response. I then fumbled
through the rest of the process which was very awkward and required
many failed tries requiring me to go from one directory to another
before I entered certain commands. Where is there some good
explanation of how to do the initial setup of a svn, please?

[google-appengine] Re: Dynamic list in django form for a pull-down menu

[Brian]

I finally figured this out. I used the tasks sample project as a
model. My approach might not be perfect, but it is working. I created
a function on Locations db to get a list of address_id for the current
user. I call this function from the view for the page with the form,
and then created a custom django form... pulling in the select options
from the address_id list. I tried this general approach previously but
could not get it to work. This might have been due to the fact that I
was not including a (hidden) field in my custom form.

Yes, just don't forget to add this to your imports:

from google.appengine.api.urlfetch import DownloadError

[google-appengine] Re: date range in query

[Arun Shanker Prasad]

Hi,

db.GqlQuery('SELECT * FROM myTable where start_date>=:cdate and
end_date<=:cdate',cdate=current_date)

You are trying to use in-equality filters on two properties in a
single query.. Does this not raise an Exception?

There was a post on how to do this more efficiently in the groups
somewhere, but in your case I think you need to query based on one
date from the datastore and do some logic in the view.

> SELECT * FROM Image where added > DATETIME(2009,1,1,0,0,0) and added <
> DATETIME(2009,2,1,0,0,0)

In this example both are applied to the same property.

Thanks,
Arun Shanker Prasad.

Hi,

We have the application configured in our local server and store the
application data in SQLite database . I want to push the data from our
local SQLite database to Google App Engine datastore. I don't know how
to upload the SQLite data to Google App Engine datastore.
Kindly help me.

You will probably need to convert the data for each table into CSV files and
use the bulkload_client.py script that is present in the root directory of
the google appengine SDK. You can look up online how to use it or run
"python bulkload_client.py" to see the options.

BTW, there is a server side component to the bulk uploader so you will need
to look up how to set that up.

[google-appengine] Re: UnicodeEncodeError and Django templates

[Jarek Zgoda]

If you call unicode() on unicode object such weirdness will happen.

Position 0 suggests it's a very beginning of the text. Open index.html
with hex editor and look for e3 byte value.
