[google-appengine] Re: ClientLogin error
Hi Tom,
I find that the best way to understand AuthSub is to go through the
authorization flow a few times. A good place to see this in action is
http://gdata-feedfetcher.appspot.com/ , sign in, click on a link under
"Feeds which require authorization" and observe the auth flow.
To start over with a clean slate, click the link "To erase your stored
tokens, click here"
Now for the details.
When you first visit the page which requires an auth token, there is
no auth token present, so the code generates a link to authorize this
app to access the desired resources.
After you click the "Grant Access" button on
https://www.google.com/accounts/AuthSubRequest...
you are taken back to the app, but the URL now has some addition
information: ...&token=CKasdk... Since the app sees the token in the
request URL, it does not need to generate the authorization link.
Documentation on AuthSub can be found here:
http://jscudder:6346/apis/accounts/docs/AuthSub.html#AuthProcess
Re. your assumptions on request routing:
When a request comes in for the app, the configuration in app.yaml is
checked first.
http://code.google.com/p/google-app-engine-samples/source/browse/trunk/gdata_feedfetcher/app.yaml
The first matching regular expression dictates which script is run or
which file is served. In this case, visiting anything beginning
with /... will cause feedfetcher.py to run.
http://code.google.com/p/google-app-engine-samples/source/browse/trunk/gdata_feedfetcher/feedfetcher.py
In feedfetcher.py, the statment webapp.WSGIApplication([('/',
Fetcher),...]) sets request routing rules within this script and
directs the request to the desired RequestHandler class (in this case
Fetcher).
Since the browser is performing an HTTP GET, the get method in Fetcher
is invoked, and the get method examines the currently requested URL
for additional information. I hope this helps, I feel like this may be
a lot :)
Happy coding,
Jeff

[google-appengine] Re: Isolated Application Deployment Instances
Your day is currently made. Your customers sets up a google apps or
gae account, and then add you as a developer. They "own" the account -
billing, data, management is all their responsibility, and it is as
well insulated from other customers of yours as from any other random
GAE user. As a developer you can upload new versions of the app.
Note the "currently" in my first sentence. At the moment there is no
way to download your code from GAE, so your code cannot be retrieved
by your customers. However, many, many people have railed against this
- they have mangled their local code somehow and want to get the
production code back off GAE. The accepted wisdom is that any
developer who doesn't use version control and backups obviously
doesn't place any value on their code, and so neither should anyone
else. And those of us who do value our code actually prefer the
security of there not being any way to download it from GAE. Your
situation is another argument in favour of leaving the status quo.
Cheers!
Greg.

[google-appengine] Re: Isolated Application Deployment Instances
Thanks Marzia,
For now I could live with manual deployment to each Google App account
if I thought deployment could be automated in the future. However, the
possibility you raised of Google changing its policy to allow
retrieval of hosted application code is disturbing. If Google was
indeed to allow code retrieval, it should at least allow the
possibility for third-party developers to "stamp" their code as
protected.
At a more general level, I think the GAE initiative has spawned many
more questions than it has answered. This is in itself an indication
of the enthusiasm of developers. I think it is high time that Google
put together a *detailed* strategy and roadmap on issues like
deployment so that developers can move beyond experimentation and work
to a set of concrete goals. Strategically speaking, GAE developers are
currently working blind or at least taking a punt on likely outcomes.
This aspect needs to be tightened up!
Yes we are an insatiable lot and I guess Google is working flat out on
this...but that's the price of progress :)
Many thanks,

This is what I figured - so then, instead of selecting 11 stories at a time, select say, 51 stories, adjust the offset accordingly, and the user can navigate to the next/prev 3 pages. Or up it to 91 and you'll get 5 pages. I still imagine the datastore overhead would be minimal for this (although I haven't verified this and it may depend on the situation).

Thanks Andy. For now, I think I'm going to roll all the subclasses into the superclass. I only have 4 subclasses anyway, and they each only have an additional property or two. That seems to me to be the cleanest solution. You've been very helpful/informative.

See http://code.google.com/appengine/docs/datastore/entitiesandmodels.html "Unlike relational databases, the App Engine datastore does not require that all entities of a given kind have the same properties. The application can specify and enforce its data models using the model API." If you want to get theoretical, google "universal relation". (Then you'd only have one entity class and almost all of the fields would be optional, filled it as appropriate on an instance-specific basis.) > add some sort notation of which subclass it is in the key_name and That's what I'd do, but then I have 10s of db.Model subclasses so the iterative query approach simply won't work for me.

[google-appengine] Re: Isolated Application Deployment Instances
Thanks Roberto,
You have almost made my day :)
Can you clarify to what extent I can "isolate" app instances for each
of my customers?
For example...
Is it feasible to maintain separate "table sets" for 1000s of
customer?
Is it possible for one misbehaving customer "instance" to adversely
affect other customers?

rvjcallanan

[google-appengine] Re: Isolated Application Deployment Instances
Hi,
The scenario that you've described isn't yet perfectly achievable. I think
what you are essentially looking for is something along the lines of Google
Apps Labs for developers:
http://www.google.com/enterprise/marketplace/viewVendorListings?vendorId=1012
This is definitely something we would like to explore expanding in the
future, but there is no specific roadmap for such a thing.
Right now to approximate such a thing you would need each of your customers
to have an App Engine account for their domain, and add you as a developer
to their account. You could then deploy your application to their website,
but they could handle all of the billing details for that account.
This would require that you be the person to deploy new instances of that
app to individual clients. And though they wouldn't have direct access to
your code, because both you and them would be developers of the application,
it's not certain this would never change in the future (developers being
able to retrieve the code of the apps they own from App Engine).

again, you have to track traffic for each deployed app (based on

will roll out a billings service based on deployed app domains (that

[google-appengine] Re: Isolated Application Deployment Instances
Thanks James,
I may have gotten the wrong end of the stick here.
I've been playing around with the SDK up to now but have not actually
deployed yet.
Are you basically saying that I can...
1. Allow 1000s of Google Apps account holders to easily deploy
*isolated instances* of my app:
2. Protect my app code from inspection by said Google Apps account
holders.
3. Assign responsibility for hosting cost of app instances to said
Google Apps account holders (when the service is eventually monetised)
4. Roll-out software updates automatically to each Google Apps account
holder who uses my app.
If the answer is "YES" to each of the above, then you will have made
my day!!

[google-appengine] Re: Searching shortish strings for auto-completion
Thanks Adam. While the dataset in this case is pretty small (I can't imagine a user adding *that* many different things to this field), I don't want to have an arbitrary and potentially confounding cutoff when matching. Further, if it's all done in JS, I'll have to (a) load and dump out a bunch of data from the datastore with every request and (b) maintain that list client-side as it changes across ajax requests by either (1) getting a new copy of the list with every request or (2) manually updating it with new items, spilling my logic for maintaining the list into two places. My main concern is the large number of writes to enable in-word matches and the potentially large index that would result. Matching speed, as far as I can tell, should not be a problem because it's a single read over a sequential block of entities. I think I'm going to compromise a bit here and only enable beginning- of-word matches: "sa" would match "Sam" and "Sally" but not "Alyssa." That will dramatically reduce the number of writes, the size of the index and the number of matches.

[google-appengine] Re: UnboundLocalError: local variable 'before_path' referenced before assignment
Hi,
I've had no luck replicating this on my machine (Mac OS 10.5) with the
current 1.1.7 SDK, so this may be system or SDK related. For what
it's worth, this is the code i'm using (I just chose a random non-
english character in this case):
class MainHandler(webapp.RequestHandler):
def get(self):
path = os.path.join(os.path.dirname(__file__), 'templates/
hello.html')
self.response.out.write(template.render(path,
self.request.str_GET, True))
def main():
application = webapp.WSGIApplication([(urllib.quote('/ᄨᄨᄨ'),
MainHandler)],
debug=True)
wsgiref.handlers.CGIHandler().run(application)
if __name__ == '__main__':
main()
Can you provide your system details? Or is anyone else seeing this?
Have you tried to upload this to App Engine?

[google-appengine] Re: Searching shortish strings for auto-completion
I'd use javascript. Scriptaculous Autocompleter.Local Push the entire list of previously typed strings to the client on page refresh. (Or keep the last N if the list gets too big). With appropriate flags the javascript will take care of mid-word matching etc. If you try to do this kind of matching on the server it probably won't be fast enough, and you'll have to deal with lots of edge cases where you get the autocomplete response after the user has submitted the form.

[google-appengine] Re: Isolated Application Deployment Instances
Maybe I'm missing something. But it doesn't seem like it would take
much effort to write a script to automate it.
Something along the lines of:
instance_names = ('a', 'b', 'c',...)
for name in instance_names:
# change the instance name in app.yaml
# call appcfg.py
You'd probably want to keep the instance names in a database, to
associate with billing, etc, but that could be something for later
down the road.

Alas, the google charts api looks too poor for my application.

I also need to be able to click on the chart elements to link to other the detailed charts for that data, i.e. drill down. Any help?

[google-appengine] Re: Average CPU Warnings
There could be all kinds of things that cause random long periods of delay, depending on how the framework actually measures the time. For example: 1) Virtualization scheduling -- if they use something like Xen, it may at times pre-empt your entire kernel image and take time out. 2) Garbage collection -- if the process keeps running, at some point it will have accumulated enough garbage that it may need to stop-and- collect. 3) Some driver or interrupt handler -- if the measurement is in "wallclock" time, then any mis-behavior on the kernel part (flushing buffers synchronously, a driver that poll-waits for some timeout, etc) will show up as "yours." Without knowing more how the duration is calculated, and what the execution environment is in the cluster, it's really hard to focus on only one possible cause. Especially if you can't even get kernel log outputs or syslog type data from the (virtual?) machine itself.

[google-appengine] Re: Deploying to multiple Google Apps domains
Hi, A Google App Engine app can be deployed on multiple domains. The only restriction is that if you restrict authentication to a particular Google Apps domain, you can only serve traffic on that domain (meaning currently, if you want only mydomain.com users to be able to log in to your app, the app must be served off of mydomain.com). If you are using Google Accounts for login, this is not an issue. If you had an issue linking your Google App Engine App to a Google Apps domain, it is possible this is due to some difficulties users have been having with the 'www' mapping. The general directions to linking your app to a Google Apps domain are here: http://code.google.com/appengine/articles/domains.html And if this fails for the 'www' mapping, see the instructions here: http://groups.google.com/group/google-appengine/web/deleting-existing-www-mapping-from-google-apps -Marzia On Tue, Dec 9, 2008 at 4:22 PM, Andrew <[EMAIL PROTECTED]> wrote: > > I've been exploring Google App Engine and working on an app, but I > envision the app being something that would be used by different > companies on their own Apps domains.

[google-appengine] Re: 3 questions (about paging again)
Hi,
There is no difference. In addition to the index for paging, you just have
a tag property. So
# or SearchableModel
class MyProperty(db.Model):
# For paging
index = db.IntegerProperty()
my_tags = db.StringListProperty()
For the first page, you do a fetch like this:
results = MyProperty.all().filter('my_tags =',
tag).order('-index').fetch(11)
if len(results) == 11:
next_page = results[10].index
So the next page you would fetch /tag/my_tag?start=[next_page]
And the query for this would be:
results = MyProperty.all().filter('my_tags =', tag).filter('index <=',
next_page)order('-index').fetch(11)
if len(results) == 11:
next_page = results[10].index
All adding tags does is introduce an additional property to filter on, along
with the index for paging.

Hi,
If you store the tags in a list, you should be able filter on that list
using a simple equals filter, something like:
MyProperty.all().filter('my tags =', tag).filter('index <=',
starting_index).fetch(10)
Assuming you don't have a large number of tags (a couple per entry),
this shouldn't result in an exploding index.
The third question, if I interpret it correctly, is about using the
Google Search AJAX API? If you want to use the search API for your site,
and
page through the results on your site, it seems you can do pagination with
their API, the docs are available here:

I can get mako to work if I put the html in a string, but if the html is in a file then I get a django / django_helper error (see http://pastebin.com/m384339d8 -- the django (helper) error seems to be a 'ValueError' and the mako error that caused it seems to be an uncaught exception (line 19 in pastebin) for the exception 'mako.exceptions.CompileException'). Note: I set the module_directory to None so the error should not be caused by GAE trying to write a compiled .py file into the gae file system. I think mako and gae work together from these posts: http://groups.google.com/group/google-appengine/msg/42858dbd57dbc145 http://blog.pansapiens.com/2008/06/24/mako-templates-in-google-app-engine-seems-to-work-for-me/ but these posts don't use django / django helper. For django / mako integration, I use: http://code.google.com/p/django-mako/wiki/Usage My tech stack is: gae sdk 1.1.7 GAE Helper for Django r66 from trunk http://code.google.com/p/google-app-engine-django/source/checkout django v1.0 zipped file from http://github.com/Surgo/django-on-gae/tree/master and http://groups.google.com/group/google-appengine/msg/17479486c96a62b7 mako r430 from trunk djangomako 0.1.3 http://pypi.python.org/pypi/django-mako/0.1.3 Mako is a nice templating engine for programmers and it can work on gae. I'm hoping I can use it with django on gae... Also, I don't think django / django helper should produce a stack trace if the code for the django application has errors. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: YAPT - Yet Another Paging Topic
The primary reason I'd like the specific page number capability is for
the format I'm going with, it's something users expect to see. Though,
currently it looks like this is not going to be a possibility. The
primary purpose is a user may want to go back several pages just to
see what's there.
I did see the other thread, that's what I've been working off of for
my solution. Currently I'm switching my scores from integers to floats
in order to make sure I can easily make each one unique. Scores are
actually timestamps (in unix seconds) so by switching to a float I can
add .001 to create unique instances.
Using the caching library from gaeutilities, I plan to get the
previous links working correctly also. The design is
Request for list of stories with an option start index is made.
Check cache for a list with that start index, return if it exists.
Otherwise
Fetch 11 stories using the index as a starting point.
Popular a dictionary with something like
{'next': results[-1].score,
'prev': results[0].score
'stories': results 0-9 }
Cache and return it.
End result is the cache keeps the previous and next indexes making it
so you can page forward and backwards.
If a story is added, or the order changes, delete all the cache
entries.

[google-appengine] Re: Creating unique key names
A local count can be unique across URL requests that happen to hit the same process, but it can't be unique across processes. In that, a local count is like time. A datastore counter eliminates the dangling object problem because a single counter can be used to manage an arbitrarily large number of entity group types (when combined with time), but its update (once for every process that needs to generate unique names) is a bottleneck. Of course, that bottleneck can be addressed with multiple counters (so the count is actually a count/counter-name pair), reducing the problem to one of uniquely naming the counters, but that's easily solvable. (Figuring out when there's sufficient congestion to justify creating a new counter is a little tricky but it's good enough to create "more than enough" counters.) Thanks.

[google-appengine] Re: Superclass.get_by_key_name(subclass_instance.key_name) doesn't work
While GAE application code may use subclasses, the GAE datastore does
not have any knowledge of the relationship between different entity
types.
You can encode the class name/kind in your key name and then use
db.class_for_kind to get the class. However, db.class_for_kind is not
part of the documented API at this time. If you use it, you may want
to request that it be documented (so it is more likely to continue to
exist/work) by starring
http://code.google.com/p/googleappengine/issues/detail?id=800&can=4&colspec=ID%20Type%20Status%20Priority%20Stars%20Owner%20Summary%20Log%20Component
.
Note that GAE keys know their kind.

Hi Dennis - I am using an architecture similar to what you describe. Rather than use a separate server to do the pinging, I use client-side JS to do this dirty work.

[google-appengine] Re: How to get root entities only?
The characteristics of entity groups that enable performance
optimizations actually enable some fairly interesting operations.
Unfortunately, these operations are not exposed in some cases.
In this case, ancestor('__key__') should be trivial to support and not
slow things down. I don't think that it necessarily enables any
performance hacks, but it might.

[google-appengine] Re: How to open .html in .py file?
Try this.
handlers:
- url: /
static_files: static/index.html
upload: static/index.html
- url: /
static_dir: static/
It autocalls the index.html and can read all static files, e.g. all
links from index.html to another static htmls including from
subdirectories.
Think, it's enough to run static site on App Engine.
good luck.

[google-appengine] Re: Task Queues and Asynchronous Processing TODAY
You might achieve this kind of functionality (and more) using AppRocket http://code.google.com/p/approcket Although it currently doesn't have a generic queuing service built in, it's very easy to simulate. Just setup an entity in AE for asynchronous tasks, for example QueueTask and have it replicated to a MySql table.Then on hosted system you can have a simple batch process that scans the table for new records and performs the neccessary actions. This is one way I personally levarage AR functionality. Another advantage is that you can actually update data in MySQL and it will be replicated back to AE automatically. This would let you forget about AE request constrains. Kaspars --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

In app.yaml you specify which script will execute (for example,
index.py). Inside index.py you need to return a 303 Redirect as a
response, telling the user's browser to go to "www.yourdomain.com/
index.html". How you do this will depend on which web framework you
are using. In web2py, just use the redirect() global function.
After a quick search, here's a hint on how it might work in Django:
response = HttpResponseRedirect("www.yourdomain.com/index.html")

[google-appengine] Isolated Application Deployment Instances
I am new to GAE (who isn't?) and this subject has been touched on before in a number of guises but I think we could all benefit from a little more clarity. I am developing a "proof-of-concept" business app which can benefit hugely from the GAE framework. My ideal scenario is to deploy the app to each customer as a separate isolated instance, integrated within his managed Google Apps business account. The main reasons for this preference are: 1. I would like to keep customer data and bugs isolated 2. Each customer is an island as far as the application data model is concerned. One big database would require all tables and queries to be qualified by a customer ID, adding an unnecessary layer of complexity and impacting performance. 3. I would like each customer to take individual responsibility for hosting costs 4. I wish to leverage the Google Apps for managing user accounts within each organisation. 5. I wish to expose my own API to allow for customisation. Bear in mind that each app instance may have to support a few thousand users at most (but probably not millions). Right now, deploying individual app instances in the way described above is kludgy at best. While it may be feasible to do this manually for a small number of high-value customers, it is certainly not a scalable solution. There is also the issue of protecting intellectual property. I am wondering if there is anything in the "unofficial" roadmap to address this requirement in the future. I would like to start developing now on the basis that deployment of individual app instances (and updates) will eventually be a single-click operation. Is this wishful thinking? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Superclass.get_by_key_name(subclass_instance.key_name) doesn't work
I'm a Flash designer building an app in AppEngine. My knowledge of OO
principles is based on my experiences in Flash.
Consider the following from models.py:
class Question(BaseModel):
prompt = db.StringProperty(required = True)
class ShortAnswerQuestion(Question):
multiline = db.BooleanProperty(default = True)
class MultipleChoiceQuestion(Question):
choices = db.ListProperty(str)
The properties that apply to all questions are in Question, with
subclasses to describe unique cases. Now if I know the key name of a
question, I ought to be able to do this:
question = Question.get_by_key_name('question1')
However, that doesn't work. question has been set to None. To get
the expected behavior, I have to use the particular subclass, like so:
question = ShortAnswerQuestion.get_by_key_name('question1')
For obvious reasons, I don't know what subclass the elements I'm
looking for are - I only know the key_name and that they descend from
the superclass Question. What is the correct way to convert a
key_name into an object in this situation?
Thanks!

[google-appengine] Re: How to get root entities only?
Yes :)
I think Entity Groups are optimized more for performance and less for
function. (Another example to reinforce this statement is the need to
pass in the parent_id in get_by_id or the underlying assertion that
the id's may not be unique outside of the entity group)

[google-appengine] Re: url.fetch DNS cache (IP server changes)
Hi,
Since yesterday, the error is back.
from google.appengine.api import urlfetch
resp = urlfetch.fetch('http://www.hordes.fr/')
-> DownloadError: ApplicationError: 5
But it should work
I think, urlfetch is fetching the bad IP server.
Currently, I can't use the IP adress. So my app is down again
Regards
Sylvain

[google-appengine] Re: Trouble with Multiple StringListProperty() + Django Templates
In your handler, pass:
zip(entity.images, entity.snippets)
...to your template. Let's say the template variable is called
"items". Then in the template you can do:
{% for image, snippet in items %}
Do something with {{ image }} and {{ snippet }}.
{% endfor %)
Above will work in Django 1.0. If you use the built-in Django 0.96,
use this instead:
{% for item in items %}
Do something with {{ item.0 }} and {{ item.1 }}.
{% endfor %)
