[google-appengine] Tutorial: How to manage Tags and Tag clouds with AppEngine and Django
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.

[google-appengine] Re: Ajax Updater parameters transfer
For '/update_tags/mark365'
Url mapping cloud be:
('/update_tags/(.*)', UpdateTags),
And class:
class UpdateTags(BaseRequestHandler):
def get(self, mark):
Javascript:
function updateTags(mark){
new Ajax.Updater('tagging_area', '/update_tags/' + mark, {
method: 'get'
});
}
For '/update_tags?mark=mark365'
('/update_tags.*', UpdateTags),
class UpdateTags(BaseRequestHandler):
def get(self):
mark = self.request.get('mark')
function updateTags(mark){
new Ajax.Updater('tagging_area', '/update_tags?mark=' + mark, {
method: 'get'
});
}
For url '/update_tags' but with mark data in POST header
('/update_tags', UpdateTags),
class UpdateTags(BaseRequestHandler):
def post(self):
mark = self.request.get('mark')
function updateTags(mark){
new Ajax.Updater('tagging_area', '/update_tags', {
method: 'post',
parameters: { 'mark':mark }
});
}
Also your template file probably should be:
span class=itema href=javascript:updateTags({{mark}})b
{{mark}}/b/a/span
But good principle would be to separate presentation from behavior and
not to have html and javascript in same file. It depends of you
problem but something like:
span class=itema href=# class=marks id={{ mark }}strong
{{mark}}/strong/a/span
And in separate javascript file you need to have one more function
that is executed after html document downloaded:
this in html
script type=text/javascript
Event.observe(window, 'load', init);
/script
And javascript code in separate file
function init(){
$$('.marks').each(function(linkMark){
Event.observe(linkMark, 'click', updateTags);
)};
}
function updateTags(mouseInfo){
Event.stop(mouseInfo);
var mark = mouseInfo.element().id; // or var mark =
mouseInfo.element().readAttribute('id');
... and here your preferred way of sending data.
}
Hope that helped. Matija.
P.S. There could be some writing errors.

[google-appengine] Re: Avg CPU Megacycles of simple Python script to high
One write in bigtable datastore cost around 900 mcycles. One read cost
around 40 mcycles. You have one write and 10 reads and this reason why
it is 1252 avg.
There is no memcache that can help you with writing to datastore. Also
memcache can't help you in reading from datastore with standard design
(for desktop application, or even low (or expensive) scalable web
application).
Problem is in your expectation. There is probably no way in creating
cheep total scalable information system if you allow more than one
write per request.
To achieve under 1200 mcycles you need to think out of the box.
Transfer more programming logic to client side (javascript) and learn
some paging tehnics with app engine. Python code isn't expensive but
datastore operations are.
Try to read every article about app engine before you start to write
any code. My first request took around 7 mcycles, second design
15000 mcycles, and third and final design (after complete
documentation and group reading) is always under 1000 mcycles but now
instead of one web request I have more than 30 requests for same. With
smart memcache usage (for reading requests) you can have average web
request under 100 mcycles. It takes more time but when you achieve
this it is worthy.
My only problem with one write datastore operation per request is no
internal counter system. So when you implement shard counter principle
and divide this in two requests (one write plus one counter write) you
have possible problem when first write request finished nice and
second not.
So you should design your system not to depend too much on counter
information. Maybe some information purpose where 99% precision is
fine.

Hi all,

[google-appengine] Re: JSON help...
If you know that there will be always less then 20 categories (because
of request quota limit) code is simple. If it could be more, then you
need to implement some pageing tehnics.
What you need is something like this:
rez = {}
ctgs = []
i = 0
for ctg in Category.all()
i += 1
ctParent = {}
ct = {}
ct['name'] = ctg.name
ct['id'] = ctg.id # I am not sure if it is possible to have
attribute id because of name collision, but try and see...
ctParent[str(i)] = ct
ctgs.append(ctParent)
rez = { categories_num: str(i), categories: ctgs }
self.response.headers['Content-Type'] = 'application/json'
self.response.out.write(demjson.encode(rez))
P.S. Why are you using demjson if you have already simplejson in
django.utils. Also this is good memcache candidate.

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

But the definition of index sdk generates is exactly the same.
And lack of data in result set is the same.
So, I think this problem happens when server creates the index.

The collection_name part is just a shortcut for a query you can
construct yourself.
result = ModelWithRef.all().filter('refprop =', obj.key()).fetch(num)

The collection_name part of the ReferenceProperty is a really great
way of threading from another entity back to its reference.

[google-appengine] Django+Appengine vs Appengine
Group, i'm starting work on an AppEngine site and i was going to use Django (i haven't used it before), i went through the Django docs and i saw lots of useful features but many exist already on the AppEngine, such as database models and forms (through google.appengine.ext.db.djangoforms) - plus the concept of urls and views seems to be easily reproduced in AppEngine without much code. In addition to this i'm seeing that the Django admin site has been replaced by the AppEngine data viewer which isn't as powerful or customizable right now, so i'm not seeing alot of reasons to use the Django framework (other than wanting to). What are the main advantages of using Django on the AppEngine? (i can see at least two disadvantages in having an additional layer and added configuration/maintenance). Was Django made compatible with the AppEngine (through the Appengine Helper for Django) mostly for allowing users to port their existing Django apps over or does it actually extend AppEngine with added functionality? I'm probably missing something, right? Let me know, thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

Most of the time, the errors you get from your model properties will
happen when you're saving data. For instance, if you try saving a
string as an IntegerProperty, that will result in an error.
The one exception (no pun intended) is ReferenceProperty. If you have
lots of references and you're not completely careful about leaving in
bad references, it's common to be greeted with an error like
TemplateSyntaxError: Caught an exception while rendering:
ReferenceProperty failed to be resolved.
And this is if there's only one bad reference in the view. D'oh.
I could write a try/except block to try to access all the reference
properties and delete them if an exception is raised, but this
functionality could surely be useful to many other developers if there
was a more generic method than the one I'd be capable of writing. I
imagine it would take a list of model types and try to access each
reference property of each entity in each model, setting the property
to None if an exception is raised.
I'll see if I can do this myself, but it would definitely help to have
some suggestions/snippets to get me started.

I get an additional information.
I vacuumed the problem index and rebuilt the same index.
The number of result set before vacuum_index is not same as one of
after that.
Obviously, query is same.
So I think my app get into this situation while rebuilding index.
I hope gae team checks my app's index.
My app id is 'book-case-2' and kind is 'Ownership'.

niklasr,
Thank you for sharing your approach. It is very illuminating.
Andy,
I think I understand a little better and have revised our app but have
not deployed the change yet. The class Group has not been changed, and
we have not yet finalized a way to make the key_name unique by adding
a definition of class Keysorsomething() for that purpose and
enabling a dialog with the user if his/her choice has been taken. But,
I can show you the basic idea by in relation to the original group =
Group() and group.put() section.
Earlier in this thread I had suggested the following sequence of
commands and they were almost correct, but in the last line of the
sequence, instead of key, we needed g_place. With that change and
corresponding changes in two similar places in our maps.py, I think we
have what we want except that we need to add the features which direct
the user to select a unique key_name.
def post(self):
g_place = self.request.get('place')
group = Group(key_name=g_place)
group.place = g_place
key = group.put()
self.redirect(/?place=%s % key)
So, yes, I appreciate your further explanation of the differences
between key_name s and id s. I am not sure I have the full picture,
but I am past a major hurdle, for me.

[google-appengine] Re: I appear to be corrupting my datastore
Hi,
Thanks for filing the issue.
This is related to storing a floatproperty in the SDK datastore, on Macs the
datastore file may get occasionally corrupted. Currently you will need to
clear the datastore on your local machine to fix this issue.

I set up a new Score Property.

story_added = False
while story_added == False:
try:
story.put()
story_added = True

story.score = story.score + 0.001
What should happen is that when a put is attempted, a check is done to
see if a story with that score exists. If it does exist, add 0.001 and
try to put again. After adding several stories in batch mode, I can
using the data view that appears to be working, but strangely. I'll
see a score of ###.0 and then the next would be something like ###.
043, so I'm not sure what happened to .001-.0042. Also, after running
the process the datastore appears to be corrupted as well.
I'm considering swapping to using a DateTimeProperty and keying off of
the miliseconds to see if that is handled better, but I'm confused as
to why this current method is creating problems.
One thing that might be an issue is the development is happening on an
eeepc, which is a single core processor and it's SSD isn't the fast
read/write storage device.

[google-appengine] Re: Django+Appengine vs Appengine
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. What are the main advantages of using Django on the AppEngine? Well, if you ask me that would be support from the Django community (at least for Django related problems), a lot of reusable apps that will be easily portable to App Engine (in many cases you only have to port the model definitions, the rest should work), and independence of the App Engine environment. And you can make use of many of the shortcuts that are provided by Django to avoid repititive work. I think the App Engine devs chose to support Django because it is a great and very popular framework, and providing it will attract a lot of people that have experience with Django. In principle, however, every WSGI-compliant framework could be ported to appengine. If I'm informed correctly, Guido van Rossum used Django for his Rietveld project. If you want to get as much Django-Appengine integration as possible, try the app-engine-patch: http://code.google.com/p/app-engine-patch/ It even makes a lot of Django's generic views available in App Engine.

This is actually happening on Linux, not sure if that matters or not.
Clearing the datastore is my only solution to getting it back up on
the SDK currently, but once I run the routine again, it's corrupted
again. I did try converting the entire property to a
db.DateTimeProperty and adding milliseconds, and had the same
corruption issues.

[google-appengine] Re: I appear to be corrupting my datastore
Hi,
I just assumed it was Mac because it's an issue we've seen with Macs that
have 2.5.0 installed, and I'm assuming this is your Python installation?
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 version
54695 (Apr 2007), this is the underlying cause of the error message.

[google-appengine] Re: Django+Appengine vs Appengine
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(...) Also, when calling the following shortcut: get_object_or_404(MyDbModel, pk=my_id) It complains that pk is an unexpected argument. This is using the AppEngine helper (not the patch you linked to). I thought the AppEngine helper would make sure that the Django model methods would delegate to the AppEngine's version transparently but some seem to be missing - why is this?

If you want to get as much Django-Appengine integration as possible, try the app-engine-patch:http://code.google.com/p/app-engine-patch/ It even makes a lot of Django's generic views available in App Engine.

[google-appengine] Re: Difficulty Serving Static Image with static_files handler
Hi Dylan, H, this is confusing because it works perfectly for me. I made a simple application: static - photos - folder - image.jpg - folder2 - image.jpg [different image] With this in my app.yaml: - url: /photos/(.*)/(.*\.(gif|jpg)) static_files: static/photos/\1/\2 upload: static/photos/(.*)/(.*\.(gif|jpg)) And it works perfectly. The only thing I can think of that may not make this work is if you have another handler in your app.yaml that also matches those files and is defined before this one that is causing this issue. So this could 404 if your app.yaml looks like this: -app.yaml- - url: /.* script: main.py - url: /photos/(.*)/(.*\.(gif|jpg)) static_files: static/photos/\1/\2 upload: static/photos/(.*)/(.*\.(gif|jpg)) -end- Because the first handler matches all URLs. Hope this helps, if not, perhaps attach your entire app.yaml file? -Marzia On Sun, Dec 14, 2008 at 12:11 AM, Dylan Lorimer write2dy...@gmail.comwrote: Hi, In my app.yaml I have the following: - url: /photos/(.*)/(.*\.(gif|png|jpg)) static_files: static/photos/\1/\2 upload: static/photos/(.*)/(.*\.(gif|png|jpg)) My application has images that I've uploaded per the following directory structure: application root - static - photos -folder_1/image_1.jpg -folder_1/image_2.jpg -folder_2/image_3.jpg etc etc For the life of me I can't seem to serve these images successfully.

Hi,

I have read the posts about log warnings and the FAQ at
http://knol.google.com/k/marce/app-engine-community-faqs/vkzeph4si12v/1#
- From the FAQ
A: The mcycles number included in log entries includes only the CPU
consumed in the Python runtime and the datastore. The number in the
dashboard includes the mcycles used in both your code and API code.
This is why the dashboard number is usually higher.
--
I've updated this FAQ. This information isn't correct (even though I think
I may have said it, *sigh*). The most up-to-date information on high CPU
warnings can be found at:
http://code.google.com/appengine/kb/general.html#highcpu
Please consider this the canonical source of information on high CPU
warnings.
if I understand the FAQ can I write a python request handler that does
a lot of calculations and won't get a log warning?
This is maybe not true, depending on what you mean. The logs containing two
different 'warning' indicators. The first is the (possibly) colored CPU
consumption numbers on first log line. The second is something that says:
This request used a high amount of CPU, and was roughly X times over
the average
CPU request limit...
These two indicators are calculated differently. The CPU listed on the
first line is _total_ CPU used, runtime, datastore and other APIs. Since
the runtime and datastore CPU are generally much higher than any other APIs,
these numbers are the ones that weigh the most on this measurement.
The CPU that actually generates a logged warning message is _runtime only_.
If you do a lot of calculations in your runtime (sorting in memory, complex
math calculations, large module loads), you will get the log warning in your
dashboard.
The calculation has no datastore get() or put() operations and very
few python runtime calls like zip(), map(), list comprehentions.
I tested extensively the other side: heavy datastore request handlers
and noted the average CPU a request costs.
The numbers are taken from the dashboard. And about 100 to 400
requests per value of N where used to determine the average.
My test Model contained an IntegerProperty and a StringProperty. The
number was random [0..1] and the strings had 10 random lowercase
characters. I started with a datastore that contained more then 1000
of these objects.
===
The first experiment was: How much CPU does it cost to fetch N objects?
Every request reads N objects starting at a certain random number.
query.filter('num =', startNum).fetch(N)
There is a wait of 1 sec in between requests.
here are the measurements
N=0 CPU=7 Mcycle
N=1 CPU=108
N=5 CPU=264
N=10 CPU=464
N=15 CPU=663
N=20 CPU=863
N=25 CPU=1059
N=30 CPU=1260
I have made a graph of these figures: http://tinyurl.com/6hkc6q (a
very long google chart URL)
I also did the experiment to print the number and string of these N
objects with a Django template and with a Python for-loop. The Python
for-loop costs 1Mcycle extra for every value of N, the Django template
costs 6 Mcycle extra for N=30 and 3 Mcycle extra for N=5.
===
The second experiment was: How much CPU does it cost to create or
delete N objects?
A request creates N objects starting at a certain random number, n,
n+1,n+2
Puts them in a list and stores them with db.put(objlist)
The delete request reads N objects starting at a certain random
number.query.filter('num =', startNum).fetch(N)
Then calls db.delete(objlist).
There is a wait of 1 sec in between requests.
here are the measurements
N=1 createCPU=799 deleteCPU=699 Mcycle
N=2 createCPU=1589 deleteCPU=1306
N=3 createCPU=2377 deleteCPU=1957
N=4 createCPU=3150 deleteCPU=2585
N=5 createCPU=3956 deleteCPU=3216
N=10 createCPU=7900 deleteCPU=6317
A graph of these figures: http://tinyurl.com/6s3hq7
Only 2 of all these requests, a couple of 1000 in total, did result in
a log warning that I use a lot of CPU,
one for a create(N=3)[4239Mcycle] and one for a create(N=4)[5046Mcycle]
Why not the 100 create requests for N=10, and they where 1 sec apart.
( 1 sec wait after receipt of a result ).
The log warnings have a threshold of 1000Mcycle, and if I remember
correct I have read, you are allowed 2 per minute before the app is
blocked temporarily.
During the testing of this experiment I had a dashboard line telling
me a series of requests took 11000 MCycle on average, NO log warning.
Why don't these (2000Mcycle) datastore requests give a lot of log
warnings?
The time spend in my code is around 7 Mcycle (N=0).
The CPU you are seeing is most likely datastore CPU. This CPU won't result
in warning lines in your logs. Again, only runtime CPU usage will cause
these warnings to appear, and the 2/minute limit applies only to runtime CPU
and not to

[google-appengine] Re: Django+Appengine vs Appengine
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 really worth the trouble installing it with your app. Another advantage of Django is that it allows to implement custom user authentication, this is especially easy with app-engine-patch. This was actually the reason I migrated my project from webapp to Django. Other than that, webapp is a very lightweight yet flexible framework.

[google-appengine] Re: Django+Appengine vs Appengine
This is using the AppEngine helper (not the patch you linked to). I thought the AppEngine helper would make sure that the Django model methods would delegate to the AppEngine's version transparently but some seem to be missing - why is this? app-engine-patch does not try to replace appengine models. You end up with the same data access code as with the plain vanilla appengine.

[google-appengine] Unable to import non-root modules; works fine in dev_appserver
This has been driving me nuts for the better part of 3 days. I'm trying to organize my Python code, but when I move .py files out of the app's root directory, the production servers seem to be unable to import them. Yet it works perfectly fine on my local dev_appserver. Say I create a directory called code in the app root. I put a file mymodule.py in there. (There is also a blank __init__.py in code to make sure Python recognizes code as a module -- not sure if this is necessary or not, but it's there). Now I can import App Engine modules fine. And I can import any modules that are in the app's root directory. But as soon as I try import code.mymodule, the Production Server freaks out: type 'exceptions.ImportError': No module named mymodule Traceback (most recent call last): File /base/data/home/apps/rescue2012/1.330013328833611377/ handler.py, line 4, in module import code.mymodule This works just fine on my local development server. It finds mymodule.py in code, creates the .pyc, and uses it perfectly. Am I doing something wrong, or is this a bug in GAE? I know people are including libraries (newer versions of Django, etc.) in their apps, so I'm not the only person trying this. Please reveal my stupidity.

have 2.5.0 installed, and I'm assuming this is your Python installation?
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 version
54695 (Apr 2007), this is the underlying cause of the error message.

Clearing the datastore is my only solution to getting it back up on
the SDK currently, but once I run the routine again, it's corrupted
again. I did try converting the entire property to a
db.DateTimeProperty and adding milliseconds, and had the same
corruption issues.

Hi,
Thanks for filing the issue.
This is related to storing a floatproperty in the SDK datastore, on Macs
the
datastore file may get occasionally corrupted. Currently you will need
to
clear the datastore on your local machine to fix this issue.

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. Bobby On Dec 15, 5:49 pm, Alexander Kojevnikov alexan...@kojevnikov.com wrote: This is using the AppEngine helper (not the patch you linked to). I thought the AppEngine helper would make sure that the Django model methods would delegate to the AppEngine's version transparently but some seem to be missing - why is this? app-engine-patch does not try to replace appengine models. You end up with the same data access code as with the plain vanilla appengine.

[google-appengine] Re: Difficulty Serving Static Image with static_files handler
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 static_dir: static/css - url: /images static_dir: static/images - url: /js static_dir: static/js - url: /post script: main.py login: admin - url: /.* script: main.py My site is live @ http://www.jaceyphotographs.com. You can see the blog entry with missing img, and if you check the source you'll see the img URL that should resolve but isn't. It is possible that my images haven't been uploaded to app engine by the development google app engine launcher? Is there any way to verify that they indeed are on the server? Did I mention that this works perfect on my development app engine server, which is what is making this so frustrating! Cheers, dylan On Dec 15, 1:42 pm, Marzia Niccolai ma...@google.com wrote: Hi Dylan, H, this is confusing because it works perfectly for me. I made a simple application: static - photos - folder - image.jpg - folder2 - image.jpg [different image] With this in my app.yaml: - url: /photos/(.*)/(.*\.(gif|jpg)) static_files: static/photos/\1/\2 upload: static/photos/(.*)/(.*\.(gif|jpg)) And it works perfectly. The only thing I can think of that may not make this work is if you have another handler in your app.yaml that also matches those files and is defined before this one that is causing this issue. So this could 404 if your app.yaml looks like this: -app.yaml- - url: /.* script: main.py - url: /photos/(.*)/(.*\.(gif|jpg)) static_files: static/photos/\1/\2 upload: static/photos/(.*)/(.*\.(gif|jpg)) -end- Because the first handler matches all URLs.

Also your template file probably should be:
span class=itema href=javascript:updateTags({{mark}})b
{{mark}}/b/a/span
But good principle would be to separate presentation from behavior and
not to have html and javascript in same file. It depends of you
problem but something like:
span class=itema href=# class=marks id={{ mark }}strong
{{mark}}/strong/a/span
And in separate javascript file you need to have one more function
that is executed after html document downloaded:
this in html
script type=text/javascript
Event.observe(window, 'load', init);
/script
And javascript code in separate file
function init(){
$$('.marks').each(function(linkMark){
Event.observe(linkMark, 'click', updateTags);
)};
}
function updateTags(mouseInfo){
Event.stop(mouseInfo);
var mark = mouseInfo.element().id; // or var mark =
mouseInfo.element().readAttribute('id');
... and here your preferred way of sending data.
}
Hope that helped. Matija.
P.S. There could be some writing errors.

No, but you can write your own handler. Use the code from the tutorial

In your index.html change the form's action for example to /send-
email. Then in your send-email handler, override the post() method,
send an email using the appengine mail API, and finally redirect back

[google-appengine] Re: Deploying to multiple Google Apps domains
Thanks for the reply; let me just clarify one point. You say that if I restrict authentication to a particular Google Apps domain, only users from that domain will be able to login. If I use the Google Accounts login, it is not an issue. However, I wanted to do this: Corporation 1 and Corporation 2 both use Google Apps. Both deploy my app. Can j...@corporation1.com and j...@corporation2.com both login to my app? I'm under the impression that neither of the authentication modes would allow this sort of thing, since Google Apps authentication requires everyone to be on the same domain, and Google Accounts authentication requires everyone to have a Google Account (not a company-provided Apps account). On Dec 10, 12:34 pm, Marzia Niccolai ma...@google.com wrote: Hi, A Google App Engine app can be deployed on multiple domains. The only restriction is that if you restrict authentication to a particular Google Apps domain, you can only serve traffic on that domain (meaning currently, if you want only mydomain.com users to be able to log in to your app, the app must be served off of mydomain.com). If you are using Google Accounts for login, this is not an issue. If you had an issue linking your Google App Engine App to a Google Apps domain, it is possible this is due to some difficulties users have been having with the 'www' mapping.

I created my app with the default setting where any Google user can log in. Unsurprisingly I cannot log in when I use my Google Apps account. I tried adding the app to my Google Apps account (since the Dashboard has an Add more services link that allows the adding of AE apps), but that didn't help at all. Now, I can easily create a new AE app and set it to be used on my Apps domain instead of being universal. But that means I'm the only one who can ever use the app, right? Is there any way to allow multiple Apps domains to access the same AE app?
