Hi philippe, I did try the code you provided but that doesn't really work--all it does is rank the results in the order of cost. Infact, the result that is furthest away, ends up coming in first place, with the rest randomly scattered.

[google-appengine] UnicodeEncodeError when using bulkupload to download from datastore
I'm getting the following error when I download from the datastore: UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 265: ordinal not in range(128) I tracked this error down to a 'TextProperty' Field in the datastore. Any idea how I should deal with this? Also, I had a quick question about using the bulkupload.py tool. Initially, I had wanted to use it to backup the datastore--incase (during my experimentation) I accidentally messed up anything. However, now that I think about it, it'll be almost impossible to do this if my datastore structure uses reference properties right? Because deleting a table and then re-uploading it would change all the keys etc...

[google-appengine] testing application error handling
According to the google maps team, we have to expect atleast some [small] amounts of datastore errors.

[google-appengine] 500 error for static files today April 12 5:23am
Hi there, I've been encountering this problem @ around 5:23am Central Time. Two of my static files for my page (a .css and a .js) seem to consistently give a 500 error. The .css file sometimes loads (30% of the time) as I refresh. I wasn't sure where else to report this. I know its kinda early in the morning, but I got kinda worried, since my entire app could break if the server can't consistently serve a .js file!

wow, I am incredibly stupid. I didn't import the db.Model subclass..
that explains everything. Thanks alot Andy!
Also, for anyone else coming across this thread:
use childTable.all().ancestor(parent_key) to query an entity to find
its parents (instead of querying the parent table for children)

[google-appengine] Re: Store information when people log into appengine..?
hey richard,
I haven't tried this out, but here's an idea:
For your login link use:
=
real_destination = link_to_current_page
statistics_dest = link_to_statistics_page+?
real_destination=+real_destination
create_login_url(statistics_dest)
Then run your script to get ip and other information and update to
database
===
see this question:
http://groups.google.com/group/google-appengine/browse_thread/thread/3f79c80e68fd372a?hl=en#
finally go to the real_destination
self.redirect(self.request.get('real_destination'))
I'm new to python/appengine myself, so the above pseudo code is just a
guess on my part.

[google-appengine] Re: Still having trouble with high-cpu warnings for thumbnails.
I just wanted to follow up on this discussion to (shamefacedly) point out what was causing this problem: imports. I had copied and pasted some code earlier, which I had later deleted to slim down my code. What I had forgotten to do was: remove the imports for that piece of code. Once I had removed them, I noticed a great improvement in performance. Ever since I removed that piece of code + changed debug to false and removed the profiler code, I haven't had any cpu warnings for that particular piece of code. So the lesson here is: If you're having trouble reducing your CPU warnings, try looking at imports and make sure that you only call the essential ones.

Use 'exclude' to exclude stuff:

Then under the post method of the class that receives the submitted
data add:
data = RealgroupForm(data=self.request.POST)
if data.is_valid():
entity = data.save(commit=False)
entity.by = users.get_current_user()

#from django import newforms as forms
class MessageForm(djangoforms.ModelForm):
class Meta:
model = Message
***
What I want is to have the message itself submitted via the form,
but to populate the 'by' and 'chat' parameters.
I figure the form will submit some sort of chatId and userId. I'll
need to map those across to User and Chat models. Add them to the
Message model, and then I'm ready to save.
How should I go about this?
Cheers,
Peter

[google-appengine] non-unique ids in same model?
Hey, I've got Model_C which is the child of Model_P. In this case, there are about 200 Model_P entities with each one having one child. When I took a look at data viewer, I noticed that all Model_C entities had an id of 1. Is this something that only occurs for parent/child relationships? Or should I not rely on IDs to be unique within a Model that doesn't have parents? -Hadi --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
