The problem with built-in djangoforms and templates is that they are
from Django 0.96. Django 1.0 has a lot of new useful functionality, it

I had exactly the same problem a couple of months ago, took me quite a
few hours to find a solution.
Apparently the "code" name conflicts with some internal modules or
packages. I ended up renaming it to "app", this fixed the problem.

You can, at least that's what I'm seeing in my app. As far as I

Currently the only efficient way to implement paging is to pass
parameters uniquely identifying the page's last entity to the next
page handler and use it there as a starting point.

App Engine cannot spawn threads or start processes. It also has zero

implement something in the future.

De-normalise! Add a StringListProperty to the Parent, and update it
with all children of that parent. You can then query the parents
directly.
--~--~-~--~~~---~--~~
You received this message because
It will certainly work though it's not as efficient as querying de-
normalised parents. You can try this approach first and if it's not
fast enough for your app, you can always de-normalise later.

Try removing the database access history file, then restarting the
development server. The file is called dev_appserver.datastore.history
and located in the tmp directory.
The development server auto-generates the indices based on the history
file, even if you don't run the corresponding queries

I guess you are iterating over a Query or GqlQuery object to get the
entities? This explains explain why every 20th iteration. From
http://code.google.com/appengine/docs/datastore/queryclass.html :
You can include the 'shell' application from the official appengine
samples with your app, and add/edit/delete the entities from Python
shell.
Source: http://code.google.com/p/google-app-engine-samples/downloads/list
Demo: http://shell.appspot.com/

Try adding an empty __init__.py file into your DB folder. This marks
the DB folder as a 'package' and allows you to import modules from it.

It looks like you are including a leading '0' after the country code,
try removing it.

You can replace fetch(1) with get(), which is essentially the same.
Other than that, if you know your entity's id/key_name, it's slightly
faster to fetch it using get_by_id() or get_by_key_name().
The first variant is faster while the second one requires less
maintenance if you rename your documents a lot. Both will do the job.
I'd use the first, de-normalised model unless you normally have a lot
of revisions per document, modify the common document meta-data quite
often, and the meta-data

Joseph,
You can try this code:
def put(self):
count = 0
while True:
try:
return db.Model.put(self)
except:
count += 1
if count == 3:
raise

The thing is, there's no substitute for a solid html/css knowledge. No
visual html editor, and there are lots of them floating around, will
produce a consistently valid and cross-browser compatible mark-up.
Your best bet is to learn the basics, or to hire someone else to do
the job.
