[google-appengine] Re: Entities question
Chen, Some differences between using an Ownership model and using a list of references to CDs in a User entity: 1) You can store info associated with Ownership as mentioned in my previous message. So if you want to print all the CD titles owned by a user, you could denormalize CD titles and duplicate that information in Ownership entities. Then, you do a query on Ownership entities filtering for a specific User and the titles would be fetched. In the list of references, you'd have to actually retrieve each CD title or store titles in the single User entity, which leads us to #2... 2) There's a cap on number of indexed properties. See http://groups.google.com/group/google-appengine/browse_thread/thread/d5f4dcb7d00ed4c6 I haven't tested this yet, but the cap on indexed properties will really hamper your ability to have huge reference lists within a User entity. However, you could pickle/serialize your CD data into a blob or text property which aren't indexed. If you start storing the CD lists as blobs, though, you lose the ability to do queries like "Show me all users that own CD X" On Jan 16, 11:05 pm, Chen Harel wrote: > Bill if I use an ownership model, > How do you fetch all the cds of a user? > you select on Ownership, then get the tuples with user id / cd id > Now you need to fetch many cd id from the CD entity.. > So what's the difference? > If you store them as a list of IDs in the User, you still have to go > over the CD and fetch for every ID, > This still doesn't allow you to properly index your data, does it? > > On Jan 16, 8:14 pm, Bill wrote: > > > > I'm not sure I've followed you with whole Ownership model.. > > > Isn't that a RDBMS approach to the data and not BigTable's? > > > The two approaches aren't mutually exclusive.

[google-appengine] Load Quota
I'm trying to understand if when the application will be public, it will exceed quota. At the moment I'm test it by myself and I get some concerning data from the Current Load panel in the Dashboard. In fact the main script of the app shows me the current data: Requests last 3 hrs Avg CPU last hr % CPU last 3 hrs 110 662 99% The % CPU is definitely concerning since I tested the application alone in few minutes and got to the 99% for the last 3hrs!!! Unfortunately the mentioned script returns more than 2k entities, each request returns 50 and they are executed as soon the client application start if the local cached data is older than a day. I understand that this kind of application/approach is not the most suitable for GAE CPU limits, and I for this reason I cache the results with memcache for an hour. I am definitely concerned about the suitability of GAE for this kind of application. What is your opinion? Is GAE gonna be able to handle it of I have to change totally approach?

Yes, it seems like App Engine itself may be the way to go. It appears that Google sites has a limit to how many hits a site can receive , and there is no way to increase it, even through payment.

I'm doing the exact same thing. Are you stealing my Million Dollar Idea?

Here's how I do it:
def genGeocode(self):
key=" Your Google Maps API Key goes here"
url='
http://maps.google.com/maps/geo?q='+self.address+'&output=xml&key='+key
result2 = urlfetch.fetch(url)
dom2 = minidom.parseString(result2.content)
geo_status =int(dom2.getElementsByTagName("code")
[0].childNodes[0].data)
#check to see if google was able to find the coordinates for the
street address
if geo_status == 200:
coord = dom2.getElementsByTagName("coordinates")
[0].childNodes[0].data
split_coord = coord.rsplit(",")
longitude=(split_coord[0])
latitude=(split_coord[1])
self.geoPoint=latitude+""+longitude
self.geoHash = Geohash((latitude, longitude))
return 1
Any suggestion to improve my code are greatly appreciated.

[google-appengine] Re: Data Privacy
Hi Marzai, Thanks for the detailed response. It would be great to get those clarifications included in the terms of service and/or privacy policy. I can see from my post rating that some people don't share my concern, but data privacy is probably the number one barrier to commercial cloud adoption at the moment. Clear legal statements are always better than implied trust, or clarifications made in forums. I don't doubt that the constraints you have outlined are correct, but I read the privacy policy and terms of service to say something significantly different. The privacy policy explicitly lists content (including code) and says this - 'We use this information internally to deliver the best possible service to you, such as improving the Google App Engine user interface and maintaining a consistent and reliable user experience.' The terms of service say this (in section 8, which overrides any rights outlined in section 6) - 'By submitting, posting or displaying the Content on or through the Service you give Google a worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute such Content for the sole purpose of enabling Google to provide you with the Service in accordance with its privacy policy.' When you put these two statements together, Google is able to reproduce, adapt and modify developer contributed code to improve your UI, and explicitly *does not* require content owner's permission. Apparently that permission is given once the data is uploaded. I'm not trying to be difficult - that is actually what it says - and those documents are actually what business look at when making decisions. I realise that the terms of service and privacy policy are produced by the legal team and not the engineering team, and the legal guys have a responsibility to protect Google from liability and litigation. Perhaps the legal team isn't fully aware of the importance of data security to GAE adoption. It is probably the engineering team's responsibility to raise that awareness. It seems clear to me that Google's strategy is to market GAE applications to its Google Apps customers. Both offerings sustain each other, and the delivery of the reseller program is a hint that this ecosystem is well on its way to being opened up. If you want an abundance of vendor supplied, commercial quality applications in that ecosystem, then data security needs to be much more clearly respected in the legal documentation.

[google-appengine] Re: typical scenario
I really don't know much about WSGI, but this works for me. As I understand it, you should probably have 1 WSGI app in the "root" folder. It will do whatever's appropriate to load whichever "sub-app" needs to run. Then they should both be able to import from the DB folder. i.e. / -- app.yaml | main.py + app_one | __init__.py | whatever.py + app_two | __init__.py | whatever.py + DB | __init__.py | model_one.py | model_two.py | model_three.py Set up app.yaml to dispatch requests to main.py (or whatever you want to call it). Have it examine REQUEST and dispatch into app_one or app_two as needed (`import app_one.whatever`). Then files in app_one or app_two should be able to `import DB.model_one` If it's anything more than a dead-simple app, I'd break it down further than that. But that's the idea I'm using.

[google-appengine] Exploding Index
I would like to request some clarification on whether the following model with the set of queries result in an exploding index. I am trying to build a quick stock notes application where we want to add some quick notes on stocks. Stocks and Tags are both list properties. But I will not make any query that include both tags and stocks at the same time. Only ONE at a time combined with created in desc order (to get last one first). I imposed a restriction of ONLY A MAX of 3 tags allowed for any row ( same is the case with 3 stocks, restricted to max of 3) class QuickNote(db.Model): description = db.StringProperty() author = db.StringProperty() status = db.StringProperty() tags = db.StringListProperty() stocks = db.StringListProperty() created = db.DateTimeProperty(auto_now_add=True) Index : - kind: QuickNote properties: - name: tag - name: created direction: desc - kind: QuickNote properties: - name: stock - name: created direction: desc 1. A single entity will never have more than 3 values in each list and never more than one list property is used in a single query. However, I need to combine with date in desc order to retrieve latest notes. (as shown above) 2. As a whole, we might have about 1000 stocks and similar range of tags. I would like to know if this data model with the given set of queries, will result in exploding index? Also, if I have 7 more (a total of 9) different List properties (similar to stocks and tags) each with the same restriction of 3 values in a list, and they are never combined (except with date in desc order), would that result in exploding index? At any time only 2 or 3 lists will have any values filled in. Thank you very much in advance for your inputs.

[google-appengine] Re: Model.put() Override?
The "simple" answer seems to be "override the db class." That's totally off the top of my head, and it may be completely unrealistic. Something like (totally untested and almost definitely wrong. Consider it pseudo-code): class my_db(google.ext.db): def put(self, *objects, **kwargs): for o in objects: o.pre_put() super(google.ext.db, self).put(*objects, **kwargs) Then the models that were overriding put() could put that override code in pre_put() instead (and change put() to just call that before calling super().put()...). You'd have to juggle the nuances of things like post_put(), and any side-effects. But it seems like a reasonable compromise. On Jan 14, 2:22 pm, boson wrote: > That is a curious situation.

Actually, there's nothing about the UI.

[google-appengine] import google.appengine.ext.db.polymodel : No module named polymodel
According to the documentation (http://code.google.com/appengine/docs/ python/datastore/polymodelclass.html), there should be a PolyModel class in google.appengine.ext.db.polymodel. However, the program ... from google.appengine.ext.db import polymodel ... fails at runtime with an exceptions.ImportError and the message "No module named polymodel" The simlar program ... import google.appengine.ext.db.polymodel ... fails in the same way, which is comforting I suppose.

[google-appengine] djangoforms refuses to validate unchecked boolean properties
Hi,
The following snippet demonstrates the issue:
class BooleanModel(db.Model):
bool_prop = db.BooleanProperty(required=True, default=True)
class BooleanModelForm(djangoforms.ModelForm):
class Meta:
model = BooleanModel
view:
def bool_form(request):
if request.method == "POST":
f = BooleanModelForm(request.POST)
if f.is_valid():
return HttpResponseRedirect("http://www.google.com";)
else:
f = BooleanModelForm()
t = loader.get_template("template.page")
params = { 'form': f }
return HttpResponse(t.render(Context(params)))
template page:
{{ form.bool_prop }}
The template page generates a checkbox for bool_prop, which is fine.
When you check the checkbox and submit the form, the form validates
fine, bool_prop is set to True and you get redirect to google.com, but
when you uncheck the checkbox, the form fails to validate with the
error "bool_prop is required".
Is this a known bug or am I doing something wrong?
TIA
-- Joe

IANAL, but that whole "sole purpose" thing seems to actually make this safer for us developers. Then again, lawyers have completely up-ended those silly "Congress shall not..." clauses in the Bill of Rights, so they could probably use this to justify publicizing your medical records. :-/ > When you put these two statements together, Google is able to > reproduce, adapt and modify developer contributed code Again, IANAL.

I suspect you aren't giving enough credit to the legal team. It's their job to keep google from getting sued. When google does get sued (which it will), it's their job to ensure that google wins. This must balance against the marketing team's job to actually get people/developers/us to use the product. > It is probably the engineering team's > responsibility to raise that awareness. You could be right. In almost any other company, I'd agree with you. I'm willing to bet that google's lawyers are at least hip-deep when it comes to privacy concerns. As I understand it, google's business model is to analyze data and use that analysis to make a profit. This seems to be mostly through selling ads. I'm sure there are other forms of revenue (like the people who pay for premium service, enterprise search, etc). If you store data on GAE, you should expect google to be crawling it and making every penny they can out of it. The biggest risk (that I can see) might be google focusing ads from your competitors on your users. A secondary risk seems to be google actually analyzing your data and making it (and the analysis) public. I don't think the TOS allows that, but (yet again) IANAL. It could all happen "to deliver the best possible service to you." But I doubt it's the engineering team's responsibility. Maybe someone on that team should (I hate that word) step up to the plate and make sure the legal team appreciates your/our concerns, but you'd really be bet
[google-appengine] updating schema
I am following the fine article at
http://code.google.com/appengine/articles/update_schema.html
but have run into some difficulties as I am very new to this. I run
this on my development system and it works fine, but when I tried to
run it at appspot.com I get the error far below.
I have just taken the requestHandler given in the article and added it
to my map.py file? Below is my version of that requestHandler, which I
named "Update" as you can see. The only change I made in the
RequestHandler was to use my "date" field instead of the "name" field
as done in the example. And my model is named Pin, not Picture, but I
kept "pic" where the example used "pic", instead of my "pin".
*
# Request handler for the URL /update_datastore
class Update(webapp.RequestHandler):
def get(self):
name = self.request.get('date', None)
if name is None:
# First request, just get the first name out of the datastore.
pic = Pin.gql('ORDER BY name DESC').get()
name = pic.name
q = Pin.gql('WHERE name <= :1 ORDER BY name DESC', name)
pics = q.fetch(limit=2)
current_pic = pics[0]
if len(pics) == 2:
next_name = pics[1].name
next_url = '/update_datastore?date=%s' % urllib.quote
(next_name)
else:
next_name = 'FINISHED'
next_url = '/' # Finished processing, go back to main page.
# In this example, the default values of 0 for num_votes and
avg_rating are
# acceptable, so we don't need to do anything other than call put
().
current_pic.put()
context = {
'current_name': name,
'next_name': next_name,
'next_url': next_url,
}
self.response.out.write(template.render('update_datastore.html',
context))
*
I get the following error, where line 241 is this one above:
current_pic.put()

[google-appengine] Re: updating schema
As reported in my previous message, I got error an error message. Upon reviewing the datastore, I saw that only one entity had been updated, but the others were expanded to have the additional fields with the filler "" in each position, so in a sense they were updated, but the default values were not inserted. So I proceeded to try to update my other data class, which failed also, but for a different reason. The reason was something more critical, like a field name I chose did not exist, but it was the same field name "date" which appears in both classes. But the good news is that my application is up and running again, with no apparent problems, *yet*. I would like to get this issue clarified, but am not under so much pressure anymore because the app is working.

I was unclear - I was referring to AppEngine specific concerns. > Businesses frequently consider data one of their most valuable > assets. And they're reluctant to trust it with anyone else. And I've never said, suggested, or implied otherwise. We're discussing whether Google's stated policies (and previously technology) are "good enough for biz use" and possibly whether Google cares/wants them to be seen as such. While AppEngine as a whole may eventually make lots of money, the margins (and usage) may be such that biz applications don't make much money. If that's the case, Google may not want the hassle. To put it another way, Google may not be willing to accept a $50-100M risk for $3-50/month. Since that's the level of risk that Hawkett is suggesting (Yes, there is an indemnity clause in the App Engine agreement, but that's an agreement with the application vendor, not with the biz being served. Google, aka "deep pockets", will be sued.) > > Actually, there's nothing about the UI. > > That's in there. Maybe it's a recent addition? There's nothing about UI in Section 8, the section under discussion. The word "interface" only appears twice in http://code.google.com/appengine/terms.html , both times in Section 2, specifically in reference to not hacking Google's adminstrative console interface; that's not a reference to Google's use of an application's interface or the application and/or content to improve some (unspecified) user interface/experience.. There's a mention of user interface in http://code.google.com/appengine/privacy.html , which contains the following (quoted by Hawkett) "We use this information internally to deliver the best possible service to you, such as improving the Google App Engine user interface and maintaining a consistent and reliable user experience." however the information in question is"personal information" as used in http://www.google.com/privacypolicy.html and defined in http://www.google.com/privacy_faq.html#personalinfo - it has nothing to do with Content or Application. > Have I mentioned before that I really like that whole "sole purpose" > phrase? I think I have. Yes, you have. However, you didn't mention that "sole purpose" is used throughout Google documents, including in places where a "nonstandard interpretation" would cause Google considerable harm. If they're not already on (court) record with a strong interpretation, they soon will be.

[google-appengine] Re: updating schema
The python db.Model definitions are not like database table definitions. Unlike SQL schema changes, changing these python definitions doesn't do anything to the entities in the datastore. In fact, if the python definitions are changed incorrectly, the supposedly corresponding entities become inaccessible in the sense that a query or db.get will throw an exception when it tries to create a python instance corresponding to the entity retrieved from the datastore. It's probably better to think of the properties in python db.Model definitions as telling the system how to serialize/deserialize objects. If you need objects to have certain fields, it's your responsibility to ensure that the ones in the database actually do have those fields.

[google-appengine] Re: Generating cryptographically strong random numbers
According to the docs, "On a UNIX-like system this will query /dev/ urandom": http://docs.python.org/library/os.html These libraries may also be of interest to you: http://docs.python.org/library/crypto.html http://docs.python.org/library/random.html http://docs.python.org/library/uuid.html Personally, I'm using random.random() for CSRF tokens and it works great. I'm curious, what kind of application are you developing that requires this level of security?

[google-appengine] Re: How to get url from fetchurl?
You can follow redirects manually like so:
response = urlfetch.fetch(url, allow_truncated=True,
follow_redirects=False)
if 'Location' in response.headers:
url = response.headers.get('Location')
response = urlfetch.fetch(url, allow_truncated=True)
You could also loop this to follow more than one redirect.
