[google-appengine] opensocial example
I read this article: http://code.google.com/apis/opensocial/articles/appengine-0.8.html ,which is how to build an open social app with app engine, and would like to ask how to make it work. I've downloaded the app engine sdk version 1.1.3, and copied all the example files. I entered this url: http://localhost:8080/admin and initialize the datastore, and could list the data, but when I enter this url: http://localhost:8080/gifts, it lists this error: Traceback (most recent call last): File "/base/python_lib/versions/1/google/appengine/ext/webapp/ __init__.py", line 499, in __call__ handler.get(*groups) File "/base/data/home/apps/opensocial-gifts-example/ 1.329235496171126774/api.py", line 111, in get if not self._isValidSignature(): File "/base/data/home/apps/opensocial-gifts-example/ 1.329235496171126774/api.py", line 100, in _isValidSignature sig = base64.decodestring(urllib.unquote(self.request.params.mixed ()["oauth_signature"])) KeyError: 'oauth_signature' --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] pagination, again
hey, from the I/O Session [1] i can see how to create pagination based on indexes that doesn't rely on database offsets. but the example is plain simple and I am intrigued in how to do some more complex pagination in a "app-engine way". in the I/O Session example, you fetch 1 extra record to know if you have a next page, and based on that and the current page's pagination data, you can create "previous" or "next" links. now, what if we want to create a pager with links to a range of pages (the common pager we use everywhere: << previous 1 2 3 4 next >>)? to know how many items we have to paginate we can set a sharded counter (using the awesome class from our fellows here :), but how to fetch the data related to the requested page in a consistent way? or, better, how to keep the index consistent? let's say i'm displaying 20 items per page, so have the links: * page 2: /my-page?start=20 * page 3: /my-page?start=40 * etc. now, if I delete items 23, 24 and 25, my page 2 will have 17 items instead of 20. to avoid this, I'd have to rebuild the index when items are removed, which is undesired. do you have other ideas? i'd want to keep it efficient and relativelly simple, and maybe i'm just trying to do what i should not try to do. what do you think? -- rodrigo [1] http://sites.google.com/site/io/building-scalable-web-applications-with-google-app-engine --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Upload data to datastore
Hi Jeff, thanks for your interest.
Yes I'm sure about that because my program works well when is in
development.
This is the output of my client script:

4

/bulkupload
[('part1', '0'), ('part2', '0'), ('part3', '3')]

The log of the development server is:

So this show me that all is going fine.
But after un update to the GAE server, this is the result on my client

The request method POST is inappropriate for the URL

Thanks for your help.

[google-appengine] Re: reference property and pickle
That may seem "logical", but it doesn't seem to be true.
Unless otherwise specified, and the definition of db.Model does not
include any indication of "otherwise specified", pickling an instance
of a python class pickles all of its instance data. If that instance
data includes instances, those instances are pickled also, and so on.
(Again, unless otherwise specified.) In other words, pickle will
quite happily include vast amounts of data.
db.ReferenceProperty s maintain two pieces of information in the
corresponding db.Model instance, one for the key and the other for the
corresponding instance. Both can be None. The instance is filled in
on demand or when an instance is assigned to the corresponding
reference property. If said instance has been filled in, it will be
included in the pickle.
The datastore operations are not like pickle. .put({instance}) and
{instance}.put() store the key (if any) for db.ReferenceProperty s and
ignores the instance (if any).
> a = db.get(key_of_a)
# at this point a.b may have a key but will not have an instance - the
datastore
# doesn't contain instances for reference properties
# pickle.dumps(a) doesn't include an instance for a.b because a.b
doesn't have one.
> c = pickle.dumps(a)
> d = pickle.loads(c)
# immediately after the loads, d.b has a key but there's no instance
because there
# was no instance in the reference property of the pickled instance
# However, the following reference to d.b will cause an instance fetch
if the key is good
> e = d.b
# if the above instance fetch succeeded, the following will pickle the
both the instance
# and the key for d.b because the d.b reference caused a datastore
fetch and saved the result
# in d
f = pickle.dumps(d)

[google-appengine] IE can't display GAE web page while firefox can
Hi, I'm developing an app on GAE. At first, I was using web framework from GAE, everything was fine. Then I started using django framework and followed the instructions of an article from official site of GAE (Running Django on Google App Engine), then strange things happened. All my dynamic web page(which is handled by a python script and rendered through a django template) can display on firefox, everything is ok, however, none of them can display on IE, the strange part is I'm sure IE has already got the content of the web page, css files and other stuff. At first, I thought, maybe it just happened because i used a dev_server of GAE, then I update the app to GAE, still the same. Then I checked html request/response(static file can all be displayed by IE), and found nothing unusual, for example this is request/response for a dynamic web page GET / HTTP/1.1 Accept: */* Accept-Language: zh-cn UA-CPU: x86 Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727) Host: localhost:8080 Connection: Keep-Alive HTTP/1.0 200 OK Server: Development/1.0 Python/2.5.1 Date: Wed, 12 Nov 2008 13:24:53 GMT Content-Type: text/html; charset=utf-8 Cache-Control: no-cache content-length: 2701 this is request/response for static html file: GET /htdocs/help.html HTTP/1.1 Accept: */* Accept-Language: zh-cn UA-CPU: x86 Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727) Host: localhost:8080 Connection: Keep-Alive HTTP/1.0 200 Server: Development/1.0 Python/2.5.1 Date: Wed, 12 Nov 2008 13:34:43 GMT Content-type: text/html Expires: Wed, 19 Nov 2008 13:34:43 GMT Cache-Control: public, max-age=604800 content-length: 263 they all look the same to me.

[google-appengine] User login problem
Hi all! I have a problem linked to the user login... My web application should work in this way: -an external user visits my web page were there are some links -each of these shows a list of my documents (using Docs API) -each doc title, shown in the list, is a link to the doc content Now, when i have updated my application (by appcfg.py command) I have seen that an external user has to login with his google account whene he clicks on a link to obtain just the list of my docs, otherwise an authentication error occours. The credentials of my account for the client login (mail and password) are inserted in the code so it isn't their fault. I know there is the users.create_login_url(self.request.uri) function... but is there a way to avoid the user login page or to create a fake user (to insert in the code as the previous one) so that everyone can see my document list?

[google-appengine] Any way to create dynamic file
I'd like to experiment with a site creating some statistical figures on the fly.

I've already solved how the create the information content. The problem I have at the moment is how to provide the users a way to download the statistics as an Excel file. I've experimented with pyExcelrator and can get a desired outcome with it. The problem with GAE is that I can't save the outcome Excel to be downloaded as file.

Hi,
What is the error that you are seeing? And what are you trying to add to
Memcache?
Our engineers are looking in to fixing this issue with Memcache, but it's
usually not advisable to put a query object in Memcache, one almost always
wants to store the results of the query. If this is not the cause of the
issue you are seeing, please let me know.

[google-appengine] Exploding Indexes - trying to understand
Let's say I have the following model: class Person(db.Model): name = db.StringProperty() country_clubs = db.ListProperty(db.Key) credit_cards = db.ListProperty(db.Key) Where the person can belong to 10 different country clubs, and can have 15 different credit cards.

[google-appengine] Re: How to fix pickling error
If you are seeing this error message in your logs:
PicklingError: Can't pickle : it's not found as
__builtin__.instancemethod
This indicates that you are storing a query object in Memcache, which is
currently causing issues. The fix that benben suggested will fix this
issue.

[google-appengine] Re: reference property and pickle
pickle.dumps(a) returns a str that is somewhat readable, so why not look at it? (pickle.dumps(v, n) is readable when n=0, the default.) In the following, c will not include the instance corresponding to a.b - it will just have the key (if any) because a came directly from the datastore. If e is not None after "e = d.b", look at pickle.dumps(d). You'll see an instance and a key for d.b. (They'll be stored in different instance variables - I think that the key will be in "_b" and the instance will be in "__RESOLVED_b".) If f is not None after "f = a.b", you'll see both an instance and a key in pickle.dumps(a). (Do "f = a.b" after "c = pickle.dumps(a)".)

It only explodes if you query them together. but I guess you don't need to query credit_cards with country_clubs at the same time, since credit_cards will be unique.

Yes, I can write also to StringIO. I tried something like this:

wb.save(xlfile)
But anyhow I get the same error message - since GAE seems to not like
certain file opening modes:
raise IOError('invalid mode: %s' % mode)
IOError: invalid mode: wb

[google-appengine] Background image not showing in Firefox when accessed through dev_appserver
Hi,
In html template, I have some background images through inline css in
the table tag.
style="background-image: url('images/aboout_us.jpeg')"
There four such tables in the template, each one having different
background images, size ranging from 5KB to 60KB.
The images show up properly in Firefox if the page is directly viewed
through file protocol or if accessed from Apache server.
It also shows up properly when accessed from dev_Appserver and viewed
in IE.
But when it is accessed from dev_appserver and viewed in firefox, the
behavior is erratic. All the four images do not show up at the same
time, and on repeated refresh of the browser, none, any one or more of
the images will show up and others would not show. Out of the four
anyone can show up and there is no co-relation with the size of the
image.
Evidently it is not a coding error, as the behavior is not consistent.
My hunch is that it is something to do with how firefox is requesting
for the images and how dev_appserver is responding to the same.
>From the debug messages on the dev_appserver, the GET of the images
do now show up in a regular order when accessed from firefox. But it
is very consistent and properly ordered, when accessed from the IE.
Can anyone please help me in understanding what is happening and what
might be the remedy?
Thanks in advance.

[google-appengine] Interesting How-to Datastore Question
I was wondering how to approach the following: Suppose I have three DB Models that look something like this: MainListOfArticles(db.Model): articleText=db.Text [...] CommentsOnArticles(db.Model): commentText=db.Text articleRef=db.ReferenceProperty(MainListOfArticles) userThatWrote=db.UserProperty [...] Users(db.Model): userObject=db.UserProperty [...] Now suppose I would like to retreive all articles that the user commented on, based on the recency of the latest comment on that article. I.e: when a user logs in he gets a decending list of all articles *that he commented on* sorted by how recently they were commented on (by others). To put it in other words: To get all articles based on the recency of their comments would be easy: simply retrieve the comments sorted by order descending. However, I would like a way to specifically retreive those that the user commented on. Another point: I want the solution to scale. Keep in mind that there could be an infinite number of articles and users. So storing them in an individual entity would not work. There is a 1MB limit per entity (that probably squashes many possible solutions).

[google-appengine] Re: Interesting How-to Datastore Question
Great question! I have a somewhat similar model in my app (it's not articles but the query is similar), here's how I do it: I de-normalise the data specifically for this query, that is I have a kind: UserComment: user = db.UserProperty() last_commented = db.DateTimeProperty() # de-normalised data from the article model (key, title, slug, etc). When the user creates a comment, I add a UserComment if it's the first comment for the user in this article. I also add an entity to the job queue model for background processing. The background worker (triggered by pinging from an external box) updates UserComment.last_commented for all users that also commented the article. It's far from perfect, there's a (slight) delay in update, but otherwise it works. I'm very interested in how others would implement this.

also, you can maintain multiple datastore files and choose which one to use when you run dev_appserver. there is a switch "-- datastore_path" that lets you specify where to look for the datastore files.

[google-appengine] Re: Concurrency Control in the datastore
Thanks Alexander. So now this is my guess about the rules of the datastore's timestamp- based scheduler. If someone could, pls correct where I'm wrong in here (basically I consolidated the theoretical timestamp-based scheduler with what I understand from Ryan's presentation): Each transaction T is assigned a timestamp TS(T) at startup. Each root entity R is given a read timestamp RTS(R) and a committed timestamp CTS(R) (this is the timestamp mentioned in Ryan's presentation). 1. Transaction T wants to read some entity X whose root is R (X and R may or may not be the same). a). If TS(T) > CTS(R): T goes ahead and performs the read (retrieved data from X is respective to CTS(R)). If TS(T) > RTS(R), set RTS(R) := TS(T); otherwise leave RTS(R) intact. b). If TS(T) < CTS(R): invalid read. Rollback T (abort T and restart it with a new, larger timestamp). 2. T wants to write X. a). If TS(T) >= RTS(R) and TS(T) > CTS(R): T performs the write to X including writing the journal in R and applying that journal to X, excluding setting the new value for CTS(R). b). If TS(T) >= RTS(R), but TS(T) < CTS(R): the Thomas write rule applies here. The write by T is ignored. T is allowed to proceed without making change to R and X. c). if TS(T) < RTS(R): invalid write. T must be rolled back. 3. T completes all its actions and now wants to commit. If CTS(R) at this point is still the same as when T started, it is set to TS(T); T effectively gets committed. If CTS(R) has changed, T must be rolled back. Note that in rolling back: - If T has changed RTS(R), the old value must be restored. - T may be retried at most n number of times (currently n is set to 4?). I'd appreciate if someone could give comments asap on what I outlined above.
