[google-appengine] Modeling Article Error
I'm not sure if this is big enough to be posted in the issue tracker,
but I noticed a small coding mistake when I was reading the Datastore
Modeling article at http://code.google.com/appengine/articles/modeling.html
Right at the bottom of the "One to Many" section, is the following
paragraph followed by a line of code:
"When Scott loses his phone, it's easy enough to delete that record.
Just delete the PhoneNumber instance and it can no longer be queried
for:"
jack.phone_numbers.filter('phone_type =', 'home').get().delete()
Shouldn't the line of code be:
scott.phone_numbers.filter('phone_type =', 'home').get().delete()

Yes, I understand, but the thing is that the query is exactly the same for all dynamically created kinds.

Hi, I created an issue about programmatic access to an index managment api the other month because I have similar problems. I am on my phone at the moment so I can't remember the URL of the issue.

[google-appengine] Re: Getting malformed or illegal request from google staticmap
I think you might need to remove the map api key from the urlencode
call and then just add it to the url manually afterwards. encoding
might be changing the key value

[google-appengine] Memcache Question
I'm optimizing my code to use memcache, can anyone tell me the
difference between using memcache like this...
memcache.add(key="Registration'+users.get_current_user()",
value=query, time=3600)
versus this way...
memcache.add('Registration'+users.get_current_user(), query
I found one way while watching the building-scalable-web-applications-
with-google-app-engine video and the other in the memcache
documentation.
I'm thinking the second example appends data to the memcachce key and
the first replaces what's in the specific memcache key with the new
value. or is there no difference??

This is really important to note: if you're using the memcache for your application settings, you probably want it to be backed by a datastore entity -- don't just store the settings in the memcache, or you'll randomly lose them and revert back to your defaults. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: are numeric ids of deleted entities reused?
> good question! per-entity-group id namespaces currently live forever. > if all of the entities in a given entity group disappear, and then the > entity group later reappears, ids for new entities in that group will > not be reused. If I never allocate ids within a given entity-group namespace, does anything for that namespace live forever (after all entities in said group have been deleted)? I ask because I'm creating lots of entity groups with multiple entities where every below-root entity has an explicit name. (In other words, I'm not creating any entities that have ids within these groups.) These entity groups don't last very long and I never reuse a given entity group name (the root class name and its unique name). The total number of such groups that have entities at any given time is fairly modest, but the total number that has existed over the life of the application can be fairly large. Thus, if any information about these groups "live[s] forever", I may have a problem. > this is another implementation detail, though, not a hard guarantee! Thanks for the information. I'm clearly surprised that any information "live[s] forever" as I assumed that most applications that use entity groups would not reuse their namespaces.

[google-appengine] Re: Database wrapper for datastore
I don't mean to be pessimistic, but in my experience so far, using "relational ideas" with the datastore pretty much results in queries that consume way too much CPU time (because it involves too many datastore hits). Data modelling using the datastore is quite different than normal relational modelling, and trying to adapt it will likely just (slightly) delay the inevitable.

[google-appengine] Re: Memcache Question
There is NO difference, only the first names the individual arguments,
you can call
memcache.add(time=3600, value=query
,key="Registration'+users.get_current_user()" )
and get the same result.
The second versions uses the position of the arguments.
I noticed some strange things with the quotes, single and double, are
they exactly as given in the examples?
users.get_current_user() returns a User object, this might not work
very well in adding to a String unless Python calls the __str__()
method on the User object because we try to add to a string.

[google-appengine] Re: How do you debug?
Antonin, on behalf of the community, thanks for your great
contributions!
For what it's worth (and in the absence of more formalized tools),
I've always found logging to be an effective means of debugging when
used *intelligently*. The "logging" module combined with Python's
"repr" function are quite handy.
import logging
logging.info("bout to change obj: %s" % repr(obj))
# do stuff
logging.info("changed obj: %s" % repr(obj))
After you get your trouble spot ironed out, just delete the logging
code (or clean it up into something that might be useful for later,
and change .info to .debug, etc.).

[google-appengine] Re: How do you debug?
Dan, you are right that logging may be productive in many cases.
But there are other cases when logging just doesn't work. For example
I have some library code and I want to learn how it works. Or my code
is called by library code and I want to know what is going on here,
e.g. who has called me. I don't want to modify library sources and
just looking at sources is not sufficient, because of dynamic nature
of scripting languages. I need to be able to break, see the callstack
and step through code.
Other issue is unstructured nature of log messages. If I dump object
structure with repr or str, I get poorly formated soup of members. It
is hard to read and sometimes you would like to drill down the
structure, which is not possible with dumb log strings.
Maybe I'm a little bit biased, I'm coming from Microsoft Visual Studio
world, where debuggers were always on very high level.

[google-appengine] Trying to understand model keys a little better
I was reading the article on Django Form Validation -
http://code.google.com/appengine/articles/djangoforms.html - and came
across using db.Key.from_path as a way to access a model instance.
But, I'm wondering if there's any real difference or preferred method
between these two approaches below? If you have the key, why not just
use the stringified version of it directly instead of constructing the
key from its Id?
1)
Template: a href="item/edit?key={{ item.key }}"
Code:
key = self.request.get('key')
item = Item.get(db.Key(key))
2)
Template: a href="item/edit?id={{ item.key.id }}"
Code:
id = int(self.request.get('id'))
item = Item.get(db.Key.from_path('Item', id))
Any insight?

Maybe you would want to check if the key is valid - I think Key will throw an exception if it is not. Apart that, it is cleaner and exact the same to use the stringfied version - if you have it. Constructing it from path may be useful in some cases when you have known ancestors - remember that id is only unique for the same ancestor.

[google-appengine] Re: why java
Programmers are human beings - even though we work with logic-oriented problems. We still have the natural human behavior of preferring something familiar over something unfamiliar - even if the unfamiliar environment is superior. Java is familiar because it is the primary language taught in universities and it is one of the most commonly used languages in enterprise software. >From a pure functionality standpoint, there is no reason to have Java on Google App Engine. App Engine is scalable from a system architecture standpoint. Google could just as easily have old-school BASIC as an App Engine language. Programmers have a familiarity with Java, though, so that's why the interest in Java as an App Engine language.

[google-appengine] When data is entered in the datastore, is it available at the same time to all instances?
Trying to track down a very inconsistent issue with gaeutilities session. I don't know enough about the backend to make some guesses, so am asking. When I enter an entity into BigTable, is that the only instance that exists and all front ends that users hit will read that same entity, or is there some sort of data duplication/caching that could mean that the entity is not available to an instance that the user is hitting? Session works by sending a cookie with a session token, and then that token is stored in the datastore. Every request the cookie is compared against the datastore to determine if the user is logged in. There is some memcache usage, but if the data is not found in memcache, the datastore is checked. I believe I've seen the same issue with a couple other processes I have in place for oauth/open id logins, where I've gotten strange random results of data not being found, but it's too inconsistent to track down. I can bang on the gaeutilities session without any problems. I in fact set up some javascript request buttons on the session demo to try and break it, haven't been able to replace the problem there. The application where I do see the problem is a django 1.0 application, using appengine patch. Not sure why or how that would matter but there you go. I'm going to write some test scripts against that site to see if I can get any luck duplicating the issue in a reliable sense in the next few days. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: When data is entered in the datastore, is it available at the same time to all instances?
Yes there is only one instance of the object in BigTable. If a request calls put() on an object what happens is: 1) the object is created/updated in the Datastore 2) all the index tables are updated. 3) the put() returns After the put call you know that a query for the object in the same request handler will be retrieved correctly. If another request handler does a query for the same kind it depends when the query is executed in relation to the put() call. before 1) you get the old version and the old index table between 1 and 2) you get the new version and the old index table (update), or not found (create) after 2) you get the new version and the new index table But if these requests come from a single user that does not do simultanious requests this index-situation does not apply 2009/1/1 bowman.jos...@gmail.com : > > Trying to track down a very inconsistent issue with gaeutilities > session.

[google-appengine] Re: why java
Google does have GWT. If the AppEngine had support for Java we'd be able to use Java alone to build GWT apps on the GAE. Java also has plenty of good libraries, i in particular have a few i wouldn't mind using on the server side. If support for another language is added i hope it's Java.
