Hi. I'm a J2EE, Python and Rails developer.
I've just posted a tutorial (http://xponrails.net/wrblog/view_post/19)
on how to model and manage Tags in an AppEngine-Django application.
The code works well for me, but I would like to receive your feedback.
Cheers, Stefano

Hi, djidjadji, thanks for your comment.
I tried both query as below:
query = models.Ownership.all().filter('user', user),filter('deleted',
False).order('-created_on').fetch(offset, amount)
query = models.Ownership.all().filter('user =', user),filter('deleted
=',
The collection_name part is just a shortcut for a query you can
construct yourself.
result = ModelWithRef.all().filter('refprop =', obj.key()).fetch(num)

This is related to storing a floatproperty in the SDK datastore, on Macs the

Well, Django doesn't really extend App Engine with more functionality,
because you probably could do everything you could do in Django in
webapp and vice versa.

This is actually happening on Linux, not sure if that matters or not.

the SDK currently, but once I run the routine again, it's corrupted

Hi,
I just assumed it was Mac because it's an issue we've seen with Macs that

Generally, float values in the datastore just don't work with Python 2.5.0.
Support for buffer objects in struct.unpack was not added until

Hi,
Currently there is no way to verify this only with App Engine.
I imagine that you could build a solution that would use some kind of client
software + App Engine to check the hash of the file on the client side and
verify it against the known value stored on App Engine.

One note on portability, for example for retrieving all objects in the
datastore, sorted, in Django one could do:
Poll.objects.all().order_by(...)
Whereas in AppEngine it complains that order_by isn't defined, and i
have to use the AppEngine's version:
Poll.objects.all().order(...)

It is missing.

I like the Appengine Patch's approach the best so far, i think it's
quite good.
I'll stick with Django in hopes that eventually most of the missing
Django features and apps will be ported over (either by the Django
AppEngine-Helper or the AppEngine-Patch). Right now i've got nothing
to lose.
This is easy to do. See the mail api http://code.google.com/appengine/docs/mail/

Hi Marzia -
Thanks for your reply. So unfortunately I don't that the order of the
app.yaml entries is the culprit. Here's my app.yaml:
handlers:
- url: /photos/(.*)/(.*\.(gif|png|jpg))
static_files: static/photos/\1/\2
upload: static/photos/(.*)/(.*\.(gif|png|jpg))
- url: /css
thanks, I'll implement it in the following week and let you know how
it comes out.
