[web2py] Re: Passing arg from view to controller.
Hi Anthony,
Thanks for your reply.
> $(function() {
> $("#no_table_locality_args").autocomplete({
> source: "{{=URL('hubaddressbook', 'locality_args_autocomplete')}}" +
> "/" + $(select#no_table_word).val(),
I tried the above, which made the view's JavaScript invalid, I had to
add '' to make it valid JavaScript:
$('select#no_table_word').val()
Testing this, results in the following url:
.../init/hubaddressbook/locality_args_autocomplete/?term=Am
Adding option:selected: $('select#no_table_word
option:selected').val() as in http://api.jquery.com/val/ doesn't make
any difference.
When I hard code the .val() part with "Coach":
$(function() {
$("#no_table_locality_args").autocomplete({
source: "{{=URL('hubaddressbook', 'locality_args_autocomplete')}}"
+ "/" + "Coach",
minLength: 2
});
It all works. The url:
.../init/hubaddressbook/locality_args_autocomplete/Coach?term=Am
Removing the the jQuery UI MultiSelect from the select doesn't make
any difference.
Kind regards,
Annet

[web2py] How to optimize the output typography of blocks in web2py views?
The block instructions in web2py will cause extra blank lines in final
HTML, which are useless and ugly in HTML source code.
e.g. with
{{block head}}
{{end}}
we will get two extra blank lines in final HTML.
Demo:
http://www.haijia.org/
In the source code of the page, Line 13 and line 15 are the useless
blank lines.
I would like to get a more pretty HTML, what should I do then?
[web2py] $.ajax : how to parse data sent to the controller
Earlier i was using ajax() function.
But since it is not possible to send js array or json object, I am
trying $.ajax function.
--- View ---
var jsonObjects = [{id:1, name:"amit"}, {id:2, name:"ankit"},{id:3,
name:"atin"},{id:1, name:"puneet"}];
$.ajax({
url: "{{=URL('myControllerName')}}",
type: "POST",
context: document.body,
data: {students: JSON.stringify(jsonObjects) },
dataType: "json",
success: function(){
alert('ok');
}
});
--- end View ---
In controller, how do I access the data?
Somebody has give the code for grails as :---
//this code is written in grails
import grails.converters.JSON;
List students = JSON.parse(params.students) //students in
request params is parsed to json objects and stored in the List
println "Student id: " + students[0].studentId//first element of
the students list is accessed as a map holding a key studentId
In web2py, how to port this code?
Thanks,
Vineet
[web2py] Re: BELONGS is not supported on GAE?
I've just started looking Web2py and the Google App Engine - here is some research you might find useful. While this does not relate directly to Web2py it's worth reading/reviewing as it illustrates some gae fundamentals. http://www.arbingersys.com/20080430/google-app-engine-a-better-many-to-many-join.html Also look at this: http://web2py.com/books/default/chapter/29/6#Many-to-many,-list:,-and-contains 'Belongs' is basically an SQL construct with no GAE counterpart. With GAE you need to rethink your data models and assume you will have some level of data redundancy. Note also that the DAL interface to the GAE has some limitations and does not utilitize all the features of the GAE - but that's a separate discussion. Some issues to be aware of are: - debugging with GAE can be tricky - not clear if running a local Web2py shell is supported - have not got it to work yet - expect some surprises along the way to GAE enlightenment For some decent sample Web2py/GAE code take a look here: http://code.google.com/p/publicradioroadtrip/source/browse/ Hope this helps, BrendanC

[web2py] Re: crontab sytax
I say the book works just fine: http://web2py.com/book/default/chapter/04#Cron The syntax you want to use is: @reboot * * * * root *applications/test/controllers/private.py Set that in your app/cron/crontab and make sure your controller does db.commit() at the end. Also you need SOFTCRON = True in the wsgihandler (if you run it as WSGI script).
[web2py] Re: Validate the Checkbox
The easiest way to do that is rely on web2py model -> form transformation
and use a validator (instead of the custom form).

db.my_table.my_options.requires = [IS_IN_SET(MY_OPTIONS, multiple=True),
IS_NOT_EMPTY()]

Good tip Wikus..
you can also do the something similar with SQLFORM.factory and not
define in the model (that way no DB table is created)
in controller
MY_OPTIONS = ["a","b","c"]
form = SQLFORM.factory(
Field("my_options", "list:string",

if form.accepts(request.vars):

So jQuery doesn't find data in 'select#no_table_word' (it seems to be
returning an empty string). I assume that "Coach" can be any term to
be sent for the automplete feature. Check if the selector is named
correctly. You could add extra javascript to debug (for example send
the .val() output to a popup alert() window). Does that javascript
section start when a user types data in? (check wether the function is
called after the event)

[web2py] cached values from background tasks
In parts of my app, some needed values take a long time to generate,
so I'm farming the generation of these values out to Scheduled tasks
and designing with the expectation that some values just won't be
ready to include in a page. When ready, the generated values are then
incorporated into the page on subsequent requests or by ajax calls
from the page.
Almost always, I want to cache these generated values. I thought this
seemed a common enough need that a mechanism should be incorporated
with the task Scheduler. Here's a start at what this might look like:
def bgCache(key, db, task, args=None, time_expire=60 * 60 * 24,
cache=cache.ram):
'''
cache argument expects either cache.ram or cache.disk
If the value was sitting in the cache, return it from the cache.
If the value is not in the cache, check if task was previously run
and has completed, in which case get the output value from the task
db.
Otherwise, schedule the task and return None to indicate that the
value is not ready. TODO use a special sentinel value to indicate no
value? Maybe just throw an exception?
'''
val = cache(key, lambda: None, time_expire=time_expire)
if val == None:
# see if task has been completed and get value
val = getTaskOutput(task):
if val == None:
scheduleTask(task, args) # TODO don't schedule redundant
tasks
else:
cache(key, None)
cache(key, lambda: val, time_expire=time_expire)
return val
So calling bgCache('key'...) returns the value for 'key' if it's
already in cache or if the task to generate it has completed;
otherwise, the task is scheduled and None returned. (So None couldn't
be a valid generated value. Arguably, some other special sentinel
value should be used to indicate that the generated value is not ready
so that None could be used as a valid generated value.)
To make this work generically, the input and output to the task would
be passed through the db as JSON. If I'm not wrong, this would serve
most Scheduler use cases while obviating any custom task db tables.
Of course, the precise details and API need some thought. Perhaps
bgCache could instead be a Scheduler method called 'cache'. Any
thoughts?

[web2py] Re: math Division in web2py
This is actually just a Python quirk:
In Python 2.x, the / operator always returns an integer when both
operands are integers, e.g. (5 / 2) returns 2, not 2.5. The solution
is to simply make one or both operands a float:
percent = float(x) / y * 100 # x/y as a percentage
If you want your percent value to be an integer:
percent = int(float(x) / y * 100) # x/y as a percentage

[web2py] Re: How can I Show the html output of a controller function from shell
Are you saying you want to call a web2py URL from a script and receive the
HTML output? You should be able to do that the same way as you would any
external URL:
import urllib
html = urllib.urlopen('http://[web2py url]').read()
Or using the shortcut web2py fetch method:
from gluon.tools import fetch
html = fetch('http://[web2py url]')
If you're running the script in a web2py environment (i.e., python
web2py.py -S myapp/mycontroller -M -N -R myscript.py), you can do:
html = response.render('mycontroller/myfunction.html', myfunction())

Is that going to be 2.0? IMO, the rocket download problem which AFAIK has not yet been fixed is a blocker for 2.0 Also, IIRC, Bruno is working on Bootstrap integration -- which is probably worthy of delaying 2.0 for (Web2py 2: Now with bootstrap!)

[web2py] cache to disk zipped files
My application/controller is creating a zipped folder of files
specific to each use and then the user downloads the folder. I'm able
to create the zipped folders OK and set up the disk caching without
apparently any errors, and I see that the system is updating the files
in the applications cache folder. Is Web2Py cacheing the original
file? Web2Py is not removing the file and when I have the controller
delete the original file the application crashes upon download,
despite the download is supposed to be from the cached version of the
file.
What I want to do is have the system automatically remove the zipped
file after they have been downloaded.
I am trying to do this with:
the_path = 'theZipped_Files' + response.session_id + '.zip';
t = cache.disk('files_zipped', lambda: the_path , time_expire=3*60);
# import os;
# os.remove(the_path);
return response.stream(open(t,'rb'),chunk_size=4096)
The above code downloads the correct zipped files. If I un-comment the
above commented code, "empty" zipped files are downloaded.
Any advice appreciated - thanks in advance, James

[web2py] concurrency, web2py, and GAE
Hello all, a question about web2py and concurrent requests on GAE - I'm seeing some odd behavior and i would like to know if my theory is at all reasonable, and suggestions for testing my theory. an RTFM (read the friggen manual) response is just fine - can you point me to the manual? my assertion: on GAE web2py puts per-request items into the shared global namespace, such as db and auth. this causes problems on GAE with concurrency enabled because data gets clobbered. why do i believe this? well, i turned on concurrency (threadsafe: true) in app.yaml and after some time as the site gets loaded with real users (i have not run into this when testing probably because i don't generate enough test traffic) i see errors like: File "/base/data/home/apps/s~myapp/default-30a0bc01f698.356965928401701861/applications/myapp/controllers/admin_stores.py", line 10, in auth.settings.actions_disabled=['profile', 'change_password'] NameError: name 'auth' is not defined AttributeError: 'auth_user' object has no attribute 'preferred_store' File "/base/data/home/apps/s~myapp/default-30a0bc01f698.356965928401701861/applications/myapp/controllers/order.py", line 12, in db.store.virtualfields.append(StoreVirtualFields()) NameError: name 'db' is not defined File "/base/data/home/apps/s~myapp/default-30a0bc01f698.356965928401701861/applications/myapp/controllers/food.py", line 22, in menu response.title = response.title + " - Our Menu" TypeError: unsupported operand type(s) for +: 'NoneType' and 'str' i'd love to prove or disprove my theory that what is happening is that while the request that errors is being processed, db.py (and menu.py) is being evaluated for a second request, essentially clearing variables like db, auth, and perhaps even response (the None response.title when response.title is set in menu.py is most concerning). i admit to not fully understanding how the run_X_in_environment(), and build_environment() and python variable scoping works well enough to know if my theory is valid and how best to test my theory? i've thought about putting a sleep in db.py just to see if i can reliably re-create this type of behaviour. any thoughts? thanks, christian

[Replying to old message; I'm way behind] On Jan 15, 1:21 am, pbreit wrote: > I think web2py compares the .table files to the > database to figure out what needs to be migrated. Is this correct? Everything I've seen suggests that web2py compares the .table files to the model files (models/*.py) to determine what has changed and therefore needs migration. I have not seen any sign that web2py does introspection on the database itself.
[web2py] book says auth.archive saves old record but it actually saves the new one
The book says that auth.archive "stores a copy of the record (as it was before the update)". However with SQLFORM it appears to store a copy of the record after the update unless you do workaround (from Anthony in previous post): if form.process(...onsuccess=lambda archive: auth.archive(form, archive_current=False)) Seems to me the book version is more intuitive.

[web2py] Re: Apache/mod_wsgi: Exposing individual web2py apps alongside other non-web2py services
I faced something similar when I wanted to run two different versions of web2py (the framework itself) on one server. It worked well to use a pattern like this: WSGIScriptAliasMatch^/(someappname) /var/local/web2py/wsgihandler.py/ $1 AliasMatch ^/(someappname)/static/(.*) /var/local/web2py/ applications/$1/static/$2 That routes exactly the "/someappname/*" URLs to the particular web2py instance. I had other alias rules set up to route things to the second web2py instance. That second instance could have instead been PHP content or the like, I believe. By passing the matched app path prefix as an argument to wsgihandler.py I didn't need a routes.py file at all. The WSGI and web2py machinery took care of the details. Very slick. (Each web2py instance has its own WSGIProcessGroup associated with its directory.)

[web2py] question about response.js
Hello,
Why I can't get initialization jquery plugin code to be execute by
view?
# Controller
response.js="""$(".chzn-select").chosen();"""
I already append(pluging file and css) like this :
response.files.append(URL('static','plugin_added/harvesthq-
chosen-ada808d/chosen/chosen.css'))
response.files.append(URL('static','plugin_added/harvesthq-
chosen-ada808d/chosen/chosen.jquery.js'))
I know those works...
In the book at in core chapter is says this :
response.js can contain Javascript Code. This code will be executed if
and only if the response is received by a web2py component as
discussed in Chapter 12.
In chapter 12, there is this example :
response.js = "jQuery('#%s').hide()" % request.cid
Thanks
Richard
Re: [web2py] question about response.js
Is response.files being set by the component action, or by the page that
contains the component? If the former, it won't work, as response.files is
ignored when set in a component (response.files is used by layout.html to
include CSS and JS files in the document head and so is ignored by
components, which do not load a full page and therefore do not contain a
head).

So, I assume this is possible I am maybe wrong : db.dog.owner.requires = IS_IN_DB(db,db.person.id, db.person(db.person.id ).name) Then if that is possible, why not : db.dog.owner.requires = IS_IN_DB(db,db.person.id,'%s' % db.person( db.person.id).name db.othertable(db.person(db.person.id ).fk_to_other_table_id).field_other_table) The way your table are related affect how you have to write the request... db.table(id).field is nothing else then db(db.table.id == id).select(db.table.field).first().field Richard On Tue, Feb 21, 2012 at 5:00 PM, Ashraf Mansour wrote: > Unfortunately, did not work (both). > > Do you know of any running example? > in other words, where is it explained, old style and new style? > > On Feb 22, 12:33 am, Ashraf Mansour wrote: > > I will try both and i will let you know. > > > > On Feb 22, 12:27 am, Richard Vézina > > wrote: > > > > > > > > > > > > > > > > > On Tue, Feb 21, 2012 at 4:27 PM, Richard Vézina < > ml.richard.vez...@gmail.com > > > > > > wrote: > > > > Old > > > > > > IS_IN_DB(helper_set,'table.id','%(field1)s > (%(field2)s)',multiple=True) # > > > > One table > > > > > > Maybe this work but not sure : > > > > > > IS_IN_DB(helper_set,'table.id',db.table2(db.table1.id).fieldTable2,multiple > =True) > > > > # 2 tables > > > > > > Richard > > > > > > On Tue, Feb 21, 2012 at 4:21 PM, Ashraf Mansour < > ad...@aqar-riyadh.com>wrote: > > > > > >> Thank you for the immediate reply. > > > > > >> please rewrite the example using the old requires syntax. > > > > > >> On Feb 21, 10:39 pm, Richard Vézina > > > >> wrote: > > > >> > For represent I usually do : > > > > > >> > lambda id: db.fktable1(id).represent_field # 1 table > > > >> > lambda id: db.fktable2(db.fktable1(id).id).represent_field_table2 > # 2 > > > >> table > > > > > >> > You can maybe proceding the same way, but I am not sure...

I am sure I can just put it into a file and use response.files(URL(tofile))
It just seems to me overkill to use a file for that...

response.js does not insert a script tag into the page. Instead, the
javascript function that makes the ajax call to load the component reads
the response.js code from a special response header and eval's the code.

If it's a web2py component, why not just include the above script element
in the component's view?

Re: [web2py] question about response.js
I try to bring back in controller initialization for jquery plugins because
I am not using them everywhere most of the time and also because sometimes
I initialize them differently in particular Datatables... Also, when I
change version of the plugin I found my self to always forgot a views that
contains a plugin... So I have little fix to do... I would avoid or
minimize those little issue and I thought that bring the initalization
script in controller where I spend most of my time could be a good move...

[web2py] Understanding web2py coming from a PHP background
Hello, I am a PHP developer interested in understanding the fundamentals of web2py framework and after reading the book and the documentation, I have some questions which I would very much appreciate to have answered. 1) Why (or "is") a VPS is necessary to host web2py Python web-apps? Can it not run under any Linux shared web-host which has python installed? 2) Is web2py restrictive in any way? How broad is the freedom to define custom routes, naming controllers, models and views? Can this happen without sharing the same name? 3) What is web2py approach to configuration, settings and programming? CoC? What do you think about it? 4) Is it possible to get web2py like PHP frameworks without installations? Do an unzip and have the folder structure to develop on without admin interfaces and such? 5) What would be deemed as good read for people from PHP background to understand web2py's ways? Thank you

The only issue is that each shared hosting is a little different therefore how depends on details. What web server do they provide? Do they provide mod_wsgi? Do they assign you a port?

If they allow long running processes I'd suggest running web2py under your own account and configure their web server to act as proxy. > 2) Is web2py restrictive in any way?

[web2py] Re: Understanding web2py coming from a PHP background
1) Python hosting is much harder than PHP hosting. While hosts that support Python should be able to support Web2py, that is not always the case because they don't support one of the web server communication mechanisms such as mod_wsgi or fastcgi. If the host supports Django apps, it should be possible to get Web2py to work. 2) It's pretty flexible but there are some restrictions enforced by Web2py, Python and/or the database. Routing is pretty flexible. 3) There isn't much of a concept of config files or anything. The optional routes.py file is sort of like a config file for routes. You can place config-like settings in models files as well. I'd say CoC has an edge. 4) Once again, setting up Python apps is harder than PHP. You don't just drop files into a folder. However, once you have Web2py up and running, then you can just drop a bundle of web2py app code in the applications directory (possibly requiring a server restart). 5) The Web2py book is the best I've seen. You can get started quickly by just downloading the Windows or Mac package and running it from your own computer. Later you can figure out how to deploy to a remote web server.

[web2py] Re: Web2Py/Google App Engine Apps - How to get ID or key after Inserting New Rec
bulk insert fails? or bulk insert does not return a list of IDs? i assert that bulk insert does indeed work (at least for me 1.99.4), but that it does not return a list of IDs. google provides no way to see the IDs it has assigned in a bulk insert unless you have specified the IDs yourself (which i don't think that the web2py DAL supports at this time). i could be wrong - if you see in the google docs that they do return a list of IDs i'm happy to help with a patch! cfh
[web2py] Re: BELONGS is not supported on GAE?
what version of web2py are you using? belongs was not supported on ID at one point, but we fixed that i believe anyhow, i would write the queries for GAE like: # Construct a query to fetch all the mootid's from the group mootGroup = db(db.moot_groups.gid==groupid).select() ###NOTE: you may only have up to 30 items in a belongs (IN) statement on GAE, you might need to split the following into multiple queries # Gets moots only if the moot ID exists in the Group query moots = db((db.moots.url==request.get_vars.url)&(db.moots.id.belongs([r.id for r in mootGroup]))).select(db.moots.ALL) good luck, and ask questions - i'm running several apps of various sizes on GAE so hopefully myself and others can guide you through the GAE pitfalls! cfh
[web2py] support for bound (instance) methods for represent
Hi Massimo, Can we please add support for bound (instance) methods for represent?. I propose to add the following line (immediately after assigning "n" in "represent" function at sqlhtml.py): if getattr(f, 'im_self', None): n -= 1 At aprox. line # 41. Alternatively you can check n==1 (for one arg calls) with an else clause for two arg calls ... and removing the current else (RuntimeError). Thanks!, Carlos
[web2py] Re: support for bound (instance) methods for represent
I believe represent cal already be methods. Can you please provide an example of what you need to do and the behavior you expect? massimo On Feb 21, 7:07 pm, Carlos wrote: > Hi Massimo, > > Can we please add support for bound (instance) methods for represent?. > > I propose to add the following line (immediately after assigning "n" in > "represent" function at sqlhtml.py): > > if getattr(f, 'im_self', None): n -= 1 > > At aprox. line # 41. > > Alternatively you can check n==1 (for one arg calls) with an else clause > for two arg calls ... and removing the current else (RuntimeError). > > Thanks!, > > Carlos
[web2py] Re: Understanding web2py coming from a PHP background
Thank you, both of you. I am really struggling to understanding the very basics of how Python Web-apps work. Your answers do help. So basically, a python app (running on web2py or not) is actually an app, and it runs on Python interpreter (just like Java apps). So they also contain, naturally, the web server or a web server interface to respond to requests. One more question: PHP allows writing stupid code. Because even if a part of the code starts performing an infinite root or somthing, the process in the end dies without affecting other connections or parts of the web-app. How does this work with Python? What happens if a part of the app, during production, goes crazy? Will the web2py app crash? Will it re-launch it self automatically or is it necessary to use something like "forever"? Thanks again!
[web2py] Re: Understanding web2py coming from a PHP background
> > 3) What is web2py approach to configuration, settings and programming? > As noted, the only real configuration file is routes.py, which is optional and used for routing (URL rewrite and routes on error). In addition to the root routes.py file in the /web2py folder, you can also have app-specific routes.py files. Also, note that model files are executed on every request (unless they are in subfolders to be executed conditionally based on the controller and/or function), so app-specific configuration-like settings are sometimes put in a model file (model files are executed alphabetically, so if you want some configuration settings to be set before any other app code runs, you might put them in a model file named 0_config.py). > CoC? > Probably more so than most Python frameworks, web2py does adopt a strong "convention over configuration" philosophy (this is in contrast to the "explicit is better than implicit" Python mantra followed by most other frameworks). See http://web2py.com/books/default/chapter/29/1#Principles. In web2py, everything has sane defaults but can be customized as needed. That's why the "hello world" is as simple as: /myapp/controllers/default.py: def index(): return dict(message='Hello World') 4) Is it possible to get web2py like PHP frameworks without installations? > Do an unzip and have the folder structure to develop on without admin > interfaces and such? > Using the "admin" interface is entirely optional. You can develop using any text editor or IDE (and, in fact, you can access most of the "admin" functionality programmatically via the gluon.admin module). > 5) What would be deemed as good read for people from PHP background to > understand web2py's ways? > A little old, but you can check out http://www.web2py.com/AlterEgo/default/show/106. That's really comparing web2py to plain PHP, not PHP MVC frameworks. Compared with PHP MVC frameworks, the biggest difference is probably just the language. You should also get a good idea about how web2py works by going through the Introduction and Overview chapters of the book, as well as http://web2py.com/books/default/chapter/29/4#Workflow and http://web2py.com/books/default/chapter/29/4#Dispatching.

[web2py] Re: Web2Py/Google App Engine Apps - How to get ID or key after Inserting New Rec
howesc,
My bad - you are correct. I retested bulk insert on GAE and it does work. I
made a mistake with my syntax:
Instead of:
imgids = db.imagetag.bulk_insert(ddlist)
I was using:
imgids = db.imagetag.bulk_insert(**ddlist)
Complete example:
#Test example - Build a list of dicts to insert
ddlist = []
d1 = {'image_id':10, 'tag_id':101 }
d2 = {'image_id':10, 'tag_id':102 }
d3 = {'image_id':11, 'tag_id':333 }
ddlist.append(d1)
ddlist.append(d2)
ddlist.append(d3)
imgids = db.imagetag.bulk_insert(ddlist)
Unfortunately as you stated earlier, this inserted id's are not returned
- just a True/False indicator.

[web2py] request.user_agent() dumping
I'm trying to detect the browser being used to access my web2py app. The literature seems to recommend reading request.env.http_user_agent. But the results are a little confusing, so I'm trying request.user_agent(), which uses "gluon/contrib/ user_agent_parser.py" (as per the doc). This throws the following ticket: Traceback (most recent call last): File "N:\web2py\gluon\main.py", line 518, in wsgibase session._try_store_on_disk(request, response) File "N:\web2py\gluon\globals.py", line 528, in _try_store_on_disk cPickle.dump(dict(self), response.session_file) PicklingError: Can't pickle : it's not the same object as storage.Storage I'm on web2py v1.99.2 Thanks.
[web2py] GAE and Web2Py - Current Issues and some thoughts on Best Practices?
Just started testing a small GAE test app with Web2py. I worked with the App Engine a few years ago, but have not looked at it for a while. I know there has been some earlier discussion here re proposed DAL changes to enhance GAE support. Unfortunately the Web2Py GAE docs are a bit sparse and fragmented. It's no fun beating your head against a brick wall trying to do something the App Engine is not designed to do (e.g. lots of qns keep coming up about joins, many to many mappings which need to be rethought in GAE apps). AFAIK GAE support in Web2Py really is a moving target. I think we could use some supplementary docs here related to the GAE, together with some working examples so that people can see how familiar problems (joins) are implemented in an Web2py/GAE app. Perhaps a subsection of this forim or an alternative Web2py/GAE specific forum would be useful. There are a few on this forum who have done some GAE development with Web2py, and they have already figured out some of the issues and solutions. So far I am aware of several problems/issues - however this info needs to be managed and made available for others to refer to and update. For starters: - Separate version of DAL for GAE - ??Big Issue -IMHO if I choose a nosql approach, I accept the pros and cons - db portability is highly overrated and is market speak for lowest common denominator )?? - Bypassing DAL and making native API calls - does it ever make sense? - How to configure/run an interactive Web2Py/GAE app shell locally - How to handle Many to Many relationships (varioius alternatives) - Access to GAE key values (vs ID's) - Access to GAE ID values of new records after bulk insert - Where to find some GAE example code (here's one link http://code.google.com/p/publicradioroadtrip/, anyone got any others? - Debugging GAE apps (fwiw -WingWare IDE Pro works and they document the process - see here: http://wingware.com/doc/howtos/google-app-engine I don't have answers here - just suggesting that we provide a mechanism to inform users and share ideas/issues/ and examples. Sorry if this is a bit of a ramble, but I'd be curious to hear from other App Engine developers here.. BrendanC
