[google-appengine] Re: Closure and Google App Engine
Just for the record... my initial post was just me wanting to explore using Closure as cheaply as possible. I certainly agree that one would expect to use the Closure Compiler for a production system. But I would have thought that the goog.provide ()/goog.require() mechanism in combination with minified files on a CDN would have been an acceptable model for developers exploring Closure for the first time. Currently everything I have that is publicly hosted is either on Blogger or GAE and I don't think either of those is a natural home for the Closure Library. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] SearchableModel and the word 'done'
It seems that SearchableModel has a problem with the word 'done'. The
following code seems to find the word 'done' in all the TestItems
import logging
from google.appengine.ext import db
from google.appengine.ext import search
class TestItem(search.SearchableModel):
name = db.StringProperty()
class TestSuite(object):
def newItem(self,name):
item = TestItem()
item.name = name
item.put()
def doTest(self):
self.newItem('done item number one')
self.newItem('what should I do today')
self.newItem('hello world')
self.newItem('it should be sunny today')
logging.info('- search for items with the word "done"')
for k in TestItem.all().search('done'):
logging.info(k.name)
logging.info('- search for items with the word "today"')
for k in TestItem.all().search('today'):
logging.info(k.name)
INFO 2009-09-29 07:41:13,920 actest.py:26] - search for items
with the word "done"

[google-appengine] Re: How do I limit searchable_text_index using SearchableModel?
Whenever I've tried doing a SearchableModelDescendant.all (keys_only=True).search(query) construction, it has failed saying it doesn't understand the keys_only parameter - see 'Using __key__ and SearchableModel http://groups.google.com/group/google-appengine/browse_thread/thread/73dc1dc31bfd497b Do you know if this was fixed in a recent release?

[google-appengine] Re: Using __key__ and SearchableModel
With the SearchableModel class you get a new method called search() that takes as a parameter the terms you are searching on. AFAIK there isn't a GQL construct that matches it.

[google-appengine] Using __key__ and SearchableModel
Hi everyone, just caught up with one of those Google IO videos about developing apps on GAE. I was already using separated out index-blocks so that I could restrict what was indexed for SearchableModel. Now I just want to return the keys rather than the object themselves. Does anybody know if it is possible to return just the keys - as per SELECT __KEY__ or Query(keys_only=True) - on queries/searches using the SearchableModel class, for example: from google.appengine.ext import search class ItemIB(search.SearchableModel): name = db.StringProperty() # search for items with name that matches q, but returns entire ItemIB query = ItemIB.all().search(q) # try replacing Model.all() with db.Query(Model) doesn't work query = db.Query(ItemIB,keys_only=True).search(q) Any help very gratefully received, Adrian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Modeling mutual references
Is it possible to have two models reference each other? I can't get this to work and haven't been able to find this limitation in the documentation. As a simple example, consider: class Book(db.Model): title = db.StringProperty() first = db.ReferenceProperty(Page) class Page(db.Model): text = db.TextProperty() next = db.SelfReferenceProperty() book = db.ReferenceProperty(Book) which generates "NameError: name 'Page' is not defined" when processing the Book class definition. Is this really a limitation of the underlying data store or is it more related to how models are defined in Python? I'm guessing the solution is to record the 'first page in book' information as a separate class, for example: class FirstPage(db.Model): book = db.ReferenceProperty(Book) first = db.ReferenceProperty(Page) any pointers would be gratefully received, Adrian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Is there anyway of getting the dimensions of an image?
Hi, I want to generate a 20x20 image out of an uploaded image. Using the image API I can resize it to 20x20 but for non-square input images I get a smaller image. For example a 100x50 image would come back as a 20x10 image. The crop() method would allow me to extract a square image but to generate the input parameters - left_x=0.25, top_y=1.0, right_x=0.75, bottom_y=0.0 - I need to know the image dimensions.

[google-appengine] Re: Is there anyway of getting the dimensions of an image?
I guess I had assumed that the Image API already had the necessary functionality and that I just hadn't found it yet. Obviously it's a very small subset of PIL functionality, which people have been asking for since issue 38 - http://code.google.com/p/googleappengine/issues/detail?id=38 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
