[appengine-java] Re: Datastore W/O JDO or JPA??
I think its the only one that doesn't make you deal with Keys (including JDO) ... correct me if Im wrong here. You just use normal object references to other entities and define them as @Parent's @Child'ren or even @Component's so that its properties are embedded. No reason why you can't do that in JDO. JDO itself doesn't want implementations to expose any vendor-specific Key class either, and that is solely down to implementation details on Google's behalf. You could have String or long identities in JDO easily enough and have all other fields as embedded. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Spring Security with GAE - Adding object into HttpServletRequest does not appear to be working
Hi,
I'm also trying to get Spring security to work on GAE.
regarding your problem:
1. there is an issue with Spring Security 2.0.5 on GAE, you can find a
fix here:
http://www.google-app-engine.com/blog/post/Spring-security-fix-for-google-app-engine.aspx
2. I couldn't entirely substantiate it, but I read of a lot of
problems deployed GAE has with AOP (as opposed to Google development
environment on eclipse). maybe this has something to do with it as
well.
hope this helps a bit.

Hi,
I've created a GAE web application using Spring 3.0 and Spring
Security 2.0.5.
After a little heartache and help from reading the posts on the forum,
I managed to get it all working locally, with users able to register,
validate their accounts via email and login in securely.
When a user logs in, I wanted to make their details available across
the site. I did this by creating an Interceptor, responsible for
pulling the prinicipal from the Spring Security Authentication class
(retrieved from the SecurityContextHolder) and then placing the object
in the HttpServletRequest object. Below is a snippet of code from the
interceptor.
public void postHandle(
HttpServletRequest request,
HttpServletResponse response,
Object handler,
ModelAndView modelAndView) {
try {
Member member = securityContext.getMember();
request.setAttribute(user, member);
log.info(injecting user into request);
} catch(SecurityRuntimeException e) {
// do nothing - will be thrown if no user is logged in
}
}
The user's information is wrapped in a 'Member' object, with the
securityContext responsible for retrieving it from the
SecurityContextHolder.
Locally, on the GAE development environment, everything works fine!
The interceptor correctly places the principal in the request and my
JSP's can readily access it. However, when I deploy the application to
the app engine, it does not appear to work. The logs have not provided
any clue as to why the request does not appear to have the principal
in it.
Is there any reason why the interceptor would not work on the app
engine? Or, is it ill-advised to add objects into the
HttpServletRequest?
I'm tearing my hair out with why it's not working, and it's the only
thing within my application that isn't! So any help or advice offered
is much appreciated. I'm hoping to have my code up in the Google Code
repository so if anyone wants to have a look, they're more than
welcome.
Thanks!

Re: [appengine-java] Re: need comment on using @transactional on service layer
the jdo-gae-context.xml is only used for integration tests. Yes, it duplicates the transactions defined in the service layer, but it's configured so that any transaction already started by the service layer will be inherited by the dao layer, so it won't start a new transaction. The nontransactionalread and nontransactionalwrite in the jdoconfig.xml are there because that's what google distributes. Why, or what they do, I don't know. I just used that part as-is. Ask the google boys the what and why. The transient on the logger is just a habit, in case I were to add a logger to a model/domain/dto object.

[appengine-java] data loads for tests
I'm working on a gizmo for making it easier to load data into the local data store (e.g., desktop) when doing tests. The file format is xml; a sample follows. I'm using Apache Xerces and SAX; this is my first adventure with parsing an xml file. Basically, the structure of the xml is that the top level is a dataset, and in that you can have 0 or more entity-lists and 0 or more entities. Within an entity-list you can have 1 or more entities; the entity-list specifies the type of the enclosed entities. Within an entity you can have entity-lists and entities. Entities can have properties, of the types supported by the data store (hmm, I just realized that I need to support user defined types as well). Any nesting of entities or entity-lists within entities means that there is parenting. In the example below the two entities in the type1 entity-list are at the top/root level; the entity-list there is a convenience.

[appengine-java] New issue tracker template for production issues
Hi Everyone. Just a note that Googler replies may be slower over the next couple of weeks as we take a short pause to welcome the new year. During this break, we will be piloting a new issue tracker template for speedier resolution of production issues. In the rare event that your app experiences an urgent production-related issue that requires App Engine team assistance, such as a stuck index, quota denials, or other serving issues that aren't recorded in the error logs, please head to the issue tracker, click the New issue link, and choose Production issue from the list of available templates. http://code.google.com/p/googleappengine/issues/entry?template=Production%20issue Note that this is not for general bugs -- you should continue using the Python defect or Java defect templates for these -- and we will be closing issues that are not production related with the expectation that you will report your issue in the discussion groups or file a new bug. We're piloting this so we can more quickly help applications that require the App Engine team's direct attention, so please try to file your issues appropriately. Have a happy (and safe!) holiday, and we'll check in again soon. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [google-appengine] Re: Need Help with Datastore Query
expensive instruction to redo or question is
int(self.request.get('id')) so avoid casting for 1
2009/12/28 Ms. Jen blackpho...@gmail.com:
I tried the Meta and DjangoForms and it still did not work.
On another attempt, I tried this with the Meta djangoforms:
id = int(self.request.get('id'))
band_id = Band.getBandByID(id)
query = Band.gql(WHERE ID = :1,
'band_id')
band_edit = query.get()
self.response.out.write(template.render('editband.html',
{'band_edit':
band_edit }))
which will render the page but not the form between the
{% for band in band_band %} {% endfor %}
in the template and it is not displaying the Band.db entity
properties.
If I add :
for band in band_edit:
self.response.out.write(template.render('editband.html',
{'band_edit':
band_edit }))
I then get the error:
TypeError: 'NoneType' object is not iterable
Which leads me to think that the id as band_id is not being passed to
the query.
Anyone?

[google-appengine] Re: how to make SetKey persistent?
No, not at all. makePersistent() means the object is managed by
persistent manager. All changes made to this object should be stored.
The save call is pm.close().
And it works this way for fields like String.
If I have class
class Dummy{
@Persistent
String name;
@Persistent
ListLong list;
}
and run this code
Dummy d = new Dummy();
d.setName(name);
pm.makePersistent(d);
d.setName(new name);
pm.close();
name new name will be stored. What is correct.
But any modifications to list made after pm.makePersistent(d); are
lost.
This is a problem.

[google-appengine] What is the point of the PostalAddressProperty?
If you cannot query on or sort on the individual fields of the address it is rather useless. I could just store the field as text. I assume that the major advantage is that you can export the item in the gd: XML namespace with out doing any extra work. That being said, I would think exporting the address in a way that google contacts can read the address is far less important that being able to sort by zip code, state, city, etc... For those searching for an answer to the question of querying on a zip filed in a PostalAddressProperty or sorting on a field in a PostalAddressProperty, the overwhelming answer I have come across is you cannot. It would seem that the best solution is to store the address fields in individual variables and when a request for a gd: address or full address is made, construct the PostalAddressProperty on the fly. Perhaps the PostalAddressProperty is not documented in a way that allows me to see the value, or all of the sample applications simply make no use of addresses and I am just missing the point. If others have any examples of the value of this object please do respond. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: how to make SetKey persistent?
My experience with JPA in general has always been that operations were
wrapped in a transaction and changes were persisted on the commit() call of
the transaction object, not on the closing of the
PersistenceManager/EntityManager. When a transaction object is not used, App
Engine docs state this:
Referring to makePersistent:
The call to makePersistent() is synchronous, and doesn't return until the
object is saved and indexes are updated.
It's when you update an object that close() is used to flush the object to
persistent store:
One way to update an object with JDO is to fetch the object, then modify it
while the PersistenceManager that returned the object is still open. Changes
are persisted when the PersistenceManager is closed.
This is from this URL:
http://code.google.com/appengine/docs/java/datastore/creatinggettinganddeletingdata.html

From here: http://code.google.com/appengine/docs/python/runtime.html#The_Sandbox http://code.google.com/appengine/docs/python/runtime.html#The_Sandbox An App Engine application cannot: - write to the filesystem. Applications must use the App Engine datastorehttp://code.google.com/appengine/docs/python/datastore/ for storing persistent data. Reading from the filesystem is allowed, and all application files uploaded with the application are available. - open a socket or access another host directly. An application can use the App Engine URL fetch servicehttp://code.google.com/appengine/docs/python/urlfetch/ to make HTTP and HTTPS requests to other hosts on ports 80 and 443, respectively. - spawn a sub-process or thread. A web request to an application must be handled in a single process within a few seconds.

[google-appengine] Re: Need Help with Datastore Query
howdy jen... great to see you on App Engine!
as far as your problem goes, have you checked to see just what *are*
the IDs of the objects you've stored? you seem to be trying to select
them, but perhaps their values are not what you're expecting (hence
the query failures).
i would just like to see a query that pulls up your data entities then
displays their IDs if 'id' is a property of your object. if you're
just creating and storing them with put, you're taking the default ID
that App Engine assigns, so in these cases, you need to fetch an
entity's key in order to get to its ID... something like this:
bands = Band.gql('')
for band in bands:
self.response.out.write('br%s: %sp\n' % (band.key().id_or_name
(), band.band))
let us know what you get!

The problem seems to lie in passing the requested path id into the

This bit doesn't make sense:
id = int(self.request.get('id'))
band_id = Band.get(db.Key.from_path('Band', id))
Band.get(key) returns a model, not an 'id'. But there is an easier
way:
a_band_instance = Band.get_by_id(id)
Given the above, this next section doesn't make sense because you
already have a band object:
if band_id:
band_query = Band.gql(WHERE ID = , id)
band = band_query.fetch(1)
Unless you specifically created an 'ID' attribute in your Band model,
you are probably mistaking it for the built-in '__key__' attribute,
which is what get() and get_by_id() use in the first example.
if not band_instance:
# The 'id' you are passing in is wrong.
# Where did you get it from?
You could log in to the admin interface and use the data browser to
double-check what Band models you have saved.

[google-appengine] Re: Need Help with Datastore Query
A previous version of the AppEngine docs claimed that key_name values
couldn't be numbers (or start with numbers). Perhaps that is related
to the year old bug you describe?
The current AppEngine docs have been revised (only the double
underscore case remains), and a quick test confirms that 'numeric'
key_name are allowed (as long as they are expressed as strings).
o = Model.get_by_id( 42 )
o = Model.get_by_key_name( '56' )
The source of the value doesn't matter (URL, whatever). The type does
matter.
o = Model.get_by_id( int( v ) )
o = Model.get_by_key_name( str( v ) )
Deciding which to use, from a mixed source (ids and key_names), can
still be tricky. :)

[google-appengine] A simple search against a datastore. (Newbie to AppEngine, currently PHP/MySQL).
In trying to make a transition from a purely PHP/MySQL background to AppEngine's Python/Datastore I find myself not quite getting done what I need.

I've been doing a lot of reading and a LOT of Google searching looking for an example of what I am trying to accomplish, which one wouldn't think would be difficult to get results since I'm just basically wanting to submit multiple search criteria against the datastore and retrieving the relevant results.

[google-appengine] Google App Engine admin not logging in to Google Apps Account.
My Google Apps domain is dvir.us, and my username on it is min, so my Google Apps Account is m...@dvir.us. My Google Account is also m...@dvir.us. I wrote an app in Google App Engine with my Google Apps Account. I made an administrator page using Google's authentication mechanism. When I log in, it tells me that I am unauthorized, which is possibly because it logs in to my Google Account, m...@dvir.us, that is not in any way linked to my Google Apps Account (I wish it was). I can't register my Google Account as an admin/developer because m...@dvir.us (the Google Apps Account) is already an admin and it says that m...@dvir.us is already an admin. I added another unrelated email account as an admin, and unregistered my Google Apps Account (m...@dvir.us) from admin. I tried to resend an admin invitation to m...@dvir.us, and within the email, it asks me whether this is a Google Account or a Google Apps account. When I select the Google Account option, it makes my Google Apps Account admin instead of my Google Account. I think the best and most elegant way to fix this is to allow account linking, and to automatically link the Google Account and Google Apps Account.

Hi Everyone. Just a note that Googler replies may be slower over the next couple of weeks as we take a short pause to welcome the new year. During this break, we will be piloting a new issue tracker template for speedier resolution of production issues. In the rare event that your app experiences an urgent production-related issue that requires App Engine team assistance, such as a stuck index, quota denials, or other serving issues that aren't recorded in the error logs, please head to the issue tracker, click the New issue link, and choose Production issue from the list of available templates. http://code.google.com/p/googleappengine/issues/entry?template=Production%20issue Note that this is not for general bugs -- you should continue using the Python defect or Java defect templates for these -- and we will be closing issues that are not production related with the expectation that you will report your issue in the discussion groups or file a new bug. We're piloting this so we can more quickly help applications that require the App Engine team's direct attention, so please try to file your issues appropriately.

One of the first things I did was to make sure that the first two lines of code were actually able to get and call the ID in question. I had a test logging line that was able to get the accurate ID #. So the real issue I am having is will GAE allow me to pass a dynamic variable into the datastore? Most all of the examples in the docs are literal strings, thus I was not sure if I should be encasing the variable in quotes or not. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Need Help with Datastore Query
Thanks all for your replies and input. I was avoiding using the entity Key, as it is such a mix of alphanumeric and the entity ID is a straight iterative integer, which makes for a cleaner URL. I will try the above in the morning and report back how it goes. -- You received this message because you are subscribed to the Google Groups Google App Engine group.
