Always Craig Larman is good ref, creator model and factory design

noticed and make more specific models since models mentioned look
slightly against DRY principle and awaited already defined elsewhere.
Like redefining classes Point or Rectangle which surely have API,
for rationale farther avoid nameconflicts too and choose names spec to

 Hi,

 I have searched for some kind of best practice for environment
 architecture design in GAE but haven't found anything (yet).

 I think we need 4 environments, development, test, verification and
 production. But that is just my initial thought. So my questions are:
  - What environments do you recommend?
  - What is easiest way to set up these environments?
  - Has google any official/unofficial policy against multiple versions
 for the “same” application?

 Our idea is to use a local computer for development. And 3 GAE hosted
 environments, where:
  - test would be for unit and integration test
  - verification for end-user-tests
  - production of course for the final version.

 I'm very interested in your thoughts and experience in this area!

 Regards, Anders Moberg
Hejsan, most here depends whether python or java is chosen. Java has
more ways to solve a problem and python the obvious way. The
(python) system development model I chose is very similar to this:
dev,test,prod,live + scraps adhocratively (matching innovatively
supporting very quick decisions) switching (too) fast, also looking
for more structural approach than ad hoc. Generally going opposite way
than majority who say facts have many numbers, I use names and shapes
that are easier and more natural to understand. + There're no
conventions for version numberings also supporting less numbers more
names. Here are some threads already mentioning environments. Spec I

 Hi all,

 One question to you GAE experts. I'm using the python version by the

 I'd like to create a form in Google App Engine with 2 fields, say A
 and B, and the choices of field B is restricted by A.  For example, A
 have choices ['a', 'b'], and B have choices ['a-a','a-b','b-c','b-d'].
 and if A is selected to be 'a', then the choices for B will only have
 ['a-a','a-b'], while if A is selected to be 'b', then the choices for
 B will only have 'b-c', 'b-d'.

 I've tried searching for some possible solutions [1,2,3], and they all
 require use of python AND javascripts, where javascripts are used to
 filter out the choices of a field (whatever that means... I only have
 2 months experience in this GAE/django-like framework, and no
 experience in javascripts).

 As of now, I am planning to use the method provided in [1], but I was
 hoping if there is any other way to implement this sort of dynamically
 changing forms without using javascripts?

Sort of, primitively, yes, meta refreshing elements or whole page,
dhtml or iframe however all standard ways doing this common component
depends on javascript.
I too plan something more userfriendly than interdependent menus. A
textonly app version is very usable since we can't expect all users to
have a windowmanager for very fast textbrowsers lynx or links running
without a windowmanager.

 Thanks for any help given :)
Common types are adventure, world, place, actor, thing, player, view,
command, and prioqueue. We may view an adventure in a view in a world
looking for some special thing. Important are both classes ie thing
with name and subclasses to food, tools, or creatues and also
wellchosen data structures to serve the purpose: a prio queue with
future, a binary tree to store the gamepath or a more advanced trie
structure and store actions taken on a stack to quickly access way
back and last move in a maze. A classic maze à la Zork, thing like
Dallas Quest or any classic renewed will be fun.

 Apart from the basics like

 that map myapplication and myapplication/test, how do I map something

[google-appengine] gae-rest rss atom

2009-02-06 Thread niklasr

How do we set attributes to undisplayed / hidden / private with gae-
rest?
My rss feed seems shows too many attributes. The question is how to
set isPrivate boolean attribute for hidden content such as email
addresses.

 Is this a new development?  Last I checked, a request  1MB would just
 fail.

It's probably been possible since gae start, only too complicated.
Requests  1MB from html upload form are read:

file = self.request.POST.get('file').file.read()
len = file.__len__()

or in MB

len = file.__len__()/(1024.0*1024.0)

With above code I can determine filesizes  1 MB. Then storing and
serving the larger files requires partitioning at max 1 MB.

limits the entities, not the transport.

 If I add the following line into the beginning of function process

 I cannot add lines like the following one for the other hidden form

 form.place.value = String({{place|addslashes}});

 Perhaps I should have included the following html code in the original

 by the user, so these initial settings are revised before the form
 is POSTed).

 var map = new GMap2(document.getElementById(map),

 map.addControl(new GLargeMapControl());
 map.setCenter(new GLatLng(24.21,-41.48), 2);

 Here is another critical piece of information. If I replace the
 following

 form.center_lat.value = String(34);

 Please help with this POST problem.

I save one geopt per entity and want to display its location
breadcrumb from its view  i.e. localityname  administrativeareaname 
nation
The only way seems to be gmaps javascript api as no gae serverside
function is available for reverse geocoding.

Can we expect serverside reverse geocoding from future gae api?
Is setting page content with javascript less SEO-friendly (I think so)
as crawlers may not register javascript content?
Any other tips on locations breadcrumb navigation?

 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.

[google-appengine] Re: 3 feature requests

2008-12-11 Thread niklasr

The form preview framework works with gae and the django request
handler. Validation rules like serverside reg ex defining allowed
phonenumber etc. and related layout details e.g. a red box around any
form parameter not passing validation are related details to which I
look for a lean solution. The advantage of customizing instead of the
framework is more control over details and the disadvantage is that
there's no autogeneration of markup as with the framework. RSS and
sitemap generator are interesting to adapt to work with the default
request handler as well.

Thank you for the support.

[google-appengine] geopt filter

2008-12-02 Thread niklasr

There's the problem of show everything close to a geopt. I came
around it by iterating a 2nd time after the query and saving only
nearby entities to a new list as at most one property per query can
have inequality filter and geohash isn't usable. So we can filter and
find everything in a radius or even exactly within by geopts defined
city limits. It would however be preferred to do this without the 2nd
iteration.
L=[]
things = Thing.all().filter(modified , twomonthsback).order(-
modified)
if self.request.get('lat'):
for thing in things:
if thing.geopt:
if thing.geopt.lat  float(self.request.get
('lat')):
L.append(thing)
Despite the extra iteration this way seems better for the user than
geohash as there are no borders, Now close but different geopt inputs
will output more similar lists than with the geohash where the geohash
border could be e.g. in the middle of a locality. Please let me know
your comments.

 I used python-2.5.2.msi to install Python and selected all users
 when promoted during installation
 I created helloworld.py and app.yaml as printed on the current Getting
 Started docs using UltraEdit 14.2
 I have helloworld.py and app.yaml files in the directory c:\users\chip
 \helloworld

 Here is my helloworld.py code
 print 'Content-Type: text/plain'
 print ''
 print 'Hello, world!'

 Here is my app.yaml code
 application: helloworld
 version: 1
 runtime: python
 api_version: 1

 handlers:
 - url: /.*
   script: helloworld.py

 I try to start the server and run the app by typing dev_appserver.py
 helloworld from the C:\Users\Chip directory and get the following
 error

 C:\Users\Chipdev_appserver.py helloworld/
 ERROR    2008-11-28 12:33:15,809 dev_appserver_main.py] Fatal error
 when loading
  application configuration:
 while scanning for the next token
 found character '\t' that cannot start any token
   in helloworld/app.yaml, line 8, column 1

 When I go to my Firefox 3.0.4 browser and enterhttp://localhost:8080/
 in the address bar, the following message appears in the browser
 window
 EAccessViolation

 Any ideas what I'm doing wrong?

 Thanks,

 Chip

[google-appengine] Re: Saving files

2008-11-23 Thread niklasr

There's db.BlobProperty as file data type
blob = self.request.POST['file'].file.read()
You can store files as blobs i.e. db.BlobProperty and you could store
files  1 mb by complicatingly breaking the file into 1 mb datapieces.
I had a look here:

 I'm going over the introductory materials for the App Engine and have
 completed the tutorial.  The application I'm thinking of developing
 involves inputting data into the datastore, then extracting it in
 various ways and formatting it into web pages stored at computed
 URLs.  My reading of the App Engine docs suggests I can't do that
 since I can only store things in the datastore, not individual files.
 Just wanted to confirm that.  If that's true, any suggestions for
 workarounds?  I might be willing to bundle everything into one big
 file and e-mail someplace outside of the App Engine where the files
 get extracted and hosted, but that, too, requires storing a file,
 however briefly.

[google-appengine] Re: gql matching DateTimeProperty

2008-11-20 Thread niklasr

Thank you for replying, though it's still not matching from here.
I've this is the datastore
added -MM-DD HH:MM:SS
value: 2008-06-08 22:17:45.200477
type: gd:when

Still the following won't match
SELECT * FROM thing WHERE added = '2008-06-08 22:17:45'

It should be trivial, but how?

regards
Niklas

 Hi,

 In order to query on DateTime objects, the following methods are supported
 (fromhttp://code.google.com/appengine/docs/datastore/gqlreference.html):

 A datetime, date, or time literal, with either numeric values or a string
 representation, in the following forms:
 * DATETIME(year, month, day, hour, minute, second)
 * DATETIME('-MM-DD HH:MM:SS') [no milliseconds]
 * DATE(year, month, day)
 * DATE('-MM-DD')
 * TIME(hour, minute, second)
 * TIME('HH:MM:SS')

  How match a day or a month interval, or an exact timepoint?

[google-appengine] Re: Sample code of i18n on GAE+Django

2008-11-18 Thread niklasr

Altering settings.LANGUAGE_CODE at runtime switches languages
dynamically (while the django manual says not to i.e. You shouldn’t
alter settings in your applications at runtime)
e.g. english for .com and pt_BR for .com.br:

from django.conf import settings
if os.environ.get('HTTP_HOST'):
  url = os.environ['HTTP_HOST']
else:
  url = os.environ['SERVER_NAME']
if url.endswith('domain1.com'):
  settings.LANGUAGE_CODE = 'en'
elif url.endswith('domain2.com.br'):
  settings.LANGUAGE_CODE = 'pt_BR'

Manual pages say don't do this. The app does however dynamically
choose between english and portuguese depending on the URL this way. I
don't know why the manual advises against. Maybe performance reasons.

best regards
Niklas

 Hi,

 Thanks all for the big effort you are putting in getting i18n into
 GAE.

 Did anyone find a way to choose a language dynamically?

 All the best,
