[appengine-java] Re: Model to Optimize Queries
Also, I get this error: *Can only filter by properties of a sub-object if
the sub-object is embedded.* when I tried to access article while setting a
fitler: query.setFilter(reviewer == reviewerParam article.status =
articleStatusParam);
What am I missing?

In the second model, how will I find all Articles being reviewed by A and
B?
The only way I can think of is adding another derived field in Article:
Article {
HashSetReview reviews;
HashSetReviewer reviewers; // keys of Reviewers to help the query find
all articles reviewed by A and B
HashSetString tags;
int status; // derived from all Reviews' statuses.
}
Review {
Article article;
Reviewer reviewer;
int status;
}
Now I should be able to do reviewers.contains(A.key) and
reviewers.contains(B.key). Is that the best way?

Of course you can. JDO spec defines JDOQL, using Java syntax.
query.setFilter(reviewer == reviewerParam status == statusParam
article.tags == tagParam article.status = articleStatusParam);
What is tagParam ? an element of the hashSet?
You can't do Collection == element in Java so you can't in JDOQL.
You could do article.tags.contains(tagParam)

[appengine-java] I don't understand Relationships managed by JDO and Datanucleus in GAE
Hi there,
I am trying to handle some really simple Relationships with JDO and
Datanucleus.
I read one thread about a similar Problem. But the developer in that
thread handles the keys by himself. He generates the keys with a
KeyFactory and stores just Keys instead of the dependent Object. Do I
have to code my own Persistence-Layer for GAE, which handles
Associations? That cannot be the way to do that.
My model looks like that:
User - MobilePhone - Model Series
The MobilePhone has an owner and a creator, each identified by an
User. The MobilePhone has a Model attached which has a Series
attached.
An User can be owner and creator of many MobilePhones; a MobilePhone
needs a creator, but not necessarily an owner.
A Model can be attached to many MobilePhones, a MobilePhone needs a
Model (not null).
A Series can be attached to many Models, a Model needs a Series (not
null).
My classes look like (shorted):
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Series implements IsSerializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String term;
(..)
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Model implements IsSerializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String name;
@Persistent
private Series series;
(..)
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class MobilePhone implements IsSerializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String description;
@Persistent(dependent = false)
private User owner;
@Persistent(dependent = false)
private User creator;
@Persistent(dependent = false)
private Model model;
(..)
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class User {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String firstname;
@Persistent
private String familyname;
(..)
}
In my test I create two Users (creator and owner).
@Before
public void setup() throws Exception {
this.pm = EMF.get().getPersistenceManager();
this.owner = new User();
this.owner.setFamilyname(h);
this.owner.setFirstname(b);
this.owner = this.pm.makePersistent(this.owner);
this.creator = new User();
this.creator.setFamilyname(h);
this.creator.setFirstname(b);
this.creator = this.pm.makePersistent(this.creator);
this.assertTable(2, User.class);
}
@Test
public void createHandy() throws Exception {
Series ht = new Series();
ht.setTerm(I);
Model hm = new Model();
hm.setName(name);
hm.setSeries(ht);
MobilePhone h = new MobilePhone();
h.setCreator(this.creator);
h.setDescription(b);
h.setModel(hm);
h.setOwner(this.owner);
this.pm.makePersistent(h);
this.assertTable(1, HandyTypeSeries.class);
this.assertTable(1, HandyModel.class);
this.assertTable(1, Handy.class);
}
This works fine. But when I try to persist a MobilePhone with the
attached Users, I get the following Exception.
javax.jdo.JDOFatalUserException: Detected attempt to establish Handy
(3) as the parent of User(1) but the entity identified by User(1) has
already been persisted without a parent. A parent cannot be
established or changed once an object has been persisted.

Everything would need to run in the same thread. I think that it is possible to achieve it preserving the execution order but without any guarantee on the time where js code is executed.

http://code.google.com/appengine/docs/java/datastore/relationships.html#Dependent_Children_and_Cascading_Deletes
-
Dependent Children and Cascading Deletes
The App Engine implementation of JDO makes all owned relationships
dependent. If a parent object is deleted, all child objects are also
deleted. Breaking an owned relationship by assigning a new value to
the dependent field on the parent also deletes the old child.
As with creating and updating objects, if you need every delete in a
cascading delete to occur in a single atomic action, you must perform
the delete in a transaction.
--
So your:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class MobilePhone implements IsSerializable {
@Persistent(dependent = false)
private User creator;
.
is regarded as 'MobilePhone' being the owner of the 'User' what is you
don't expected.
If you want to keep 'non-owned' relationship between 'MobilePhone' and
'User' than the best way is simply keep the key of the User in
MobilePhone and to handle is manually.
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class MobilePhone implements IsSerializable {
@Persistent
private Key creator;
.

[appengine-java] Can't persist objects -- impossible method is called
All I'm doing is persisting an entity in the datastore. No biggie. And now I get this super weird error. What is the deal here?

[appengine-java] Cannot access field of a parent (using defaultFetchGroup)
Hi,
I'm trying to use default fetch groups to obtain fields at once (not
on demand) in my entity:
public class Survey {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName=datanucleus, key=gae.encoded-pk,
value=true)
private String idSurvey;
@Persistent
private String name;
@Persistent
private Date dateFrom;
@Persistent
private Date dateUntil;
@Persistent
private String author;
@Persistent(mappedBy = survey, defaultFetchGroup = true)
private ListResponse responseList;
}
public class Response {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName=datanucleus, key=gae.encoded-pk,
value=true)
private String idResponse;
@Persistent(defaultFetchGroup = true)
private Survey survey;
//list of all Answers in this Response
@Persistent(mappedBy=response, defaultFetchGroup = true)
private ListAnswer answerList;
}
I'm getting the entities with a method in a DAO class, so I need to
open and close the PM:
public Object getObjectByID(Class objectClass, String objectID) {
PersistenceManager pm = PMFactory.get().getPersistenceManager
();
Object o = null;
try {
o = pm.getObjectById(objectClass, objectID);
pm.retrieve(o);
} catch (JDOException jdoe) {
jdoe.printStackTrace();
} finally {
//pm.close();
}
return o;
}
When I fetch a Survey I can access the responseList and all fields in
Responses in the list. But when I fetch a Response, although I can see
the Survey (I'm using debugger in NetBeans to watch the variables),
every field of the Survey (except surveyID) is null, even if it has
been set before. So basically I can access child's fields after
obtaining the parent, but not via versa.
if I change the code in DAO to :
o = pm.getObjectById(Response.class, responseID);
pm.retrieve(o.getSurvey());
it works. Also, I could make it with not closing the PM - when the
fields are accessed they are being refreshed. What is happening? Thank
you!

[appengine-java] Re: Anyone successfully redirected naked domain to their www domain with NetworkSolutions?
After a lot of research, and some awful tech support from Network Solutions, I decided to move to another domain registrar. I picked NameCheap.com - the name itself does not inspire confidence but I found a lot of good reviews, and the services are good. One nice thing about them is that you can migrate to their DNS for free, ahead of time. This turned out to be the solution to my problem, because I will use their DNS for the next year until my time runs out with Network Solutions, and then formally move over domains to them at that point. Their DNS console is excellent although you have to know a little more about what you are doing. I set up a 301 redirect for the naked domain (@) to the www subdomain needed by Google, and it works fantastically well. - Jim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

With the Google App Engine, one must use https://domain.appspot.com for SSL. With Google, the issuer is the Google Internet Authority. I accept this, however when one uses VeriSign as the issuer, they're allowed to display a VeriSign Secured logo. This logo can also be clicked to to trigger a confirmation or verification event. Basically, it makes the users feel a bit more secure about submitting personal information and that there actually is an SSL connection. Is it possible that the Google App Engine already has a feature like this? If not, would it be possible for them to develop one?

[appengine-java] Re: Error 500
Hi, You can't add a JDK by adding the JDK's bin path to your classpath. What you need to do is go into the Java Build Path dialog, and select the JRE System Library entry. Then, click Edit. A dialog will pop up, giving you the option to select an alternate JRE. However, you probably have not registered the JDK you downloaded with Eclipse, so you'll have to click on the Installed JREs button. You'll be presented with another dialog where you'll be able to add your JDK, then when you go back to the previous dialog, you can choose the JDK that you just installed. Let me know if you run into any trouble. Rajeev On Mon, Aug 24, 2009 at 7:58 AM, HC strong.luck...@gmail.com wrote: Can U explain with picture step by step ?

The fact that it did not complain at the outset is odd. Just to be clear, you restarted Eclipse, and the error showed up right away, or did you do anything else?

Does that make sense? Should be trying something likehttp://www.datanucleus.org/products/accessplatform_1_1/jdo/attach_det... Thanks for your good advice! I am getting the same error in a similar, but different, scenario with JPA+DataNucleus+GAE ... I *think* it may be as a result that the PersistenceProvider believes that it is in control of the PK value allocation strategy, and not the application, and it is complaining because the app is setting the PK field (which would be a bad thing if the PP thought it was in charge of that field and it's contents)! That's what I think the route of my problem is ... sadly I am not sure how to resolve it! :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Then I followed the GAE Guestbook tutorial and it worked fine. Then I switched on the GWT in the plugin and enhanced the GUI to use GWT (the result is onhttp://mbi-t1.appspot.com/). During development I shared the project in my SVN repository and worked additionally on my home PC (Windows Vista SP2). There I have several Eclipse versions installed and for this project I used Eclipse Ganymede SR2 for plain Java (not JEE) that was installed in C:\eclipse34. In the Preferences - Google Section I found that the Google plugin did not recognize the included SDKs for GAE and GWT as valid. Therefore I downloaded both SDKs separately and put them into the SVN in parallel to the project folder. I also ensured that the SVN checkout folder was the same on both PCs: D:\JAVA. Also I configured the Google Plugin to use the separate SDKs on both PCs. This worked so far.. In the course of the project I configured the Java compiler to use project specific settings, as such my standard Code templates, code formatter settings, and some slightly more restrictive compiler warning settings. I'm not sure when it began that the Enhancer Builder ran in an endless loop, but now it is the case and I have to disable it in the project settings to stop this behavior. I also had the impression that when I edit some file and store it, the Enhancer Builder did not find the class to enhance, because the edited file was in a subpackage: for example: edited file: src/guestbook/client/Guestbook.java file to be enhanced: src/guestbook/Greeting.java Actually I completed the project by using ANT and used Eclipse as an editor only.

[google-appengine] Entities disappearing from index
Hi, Last week two of my users complained about entities that disappeared. I searched for the records using a simple query with no composite index and found them, and confirmed that they were not returned by a composite index that should return them. The index was up and running, and as far as I know the entities disappeared randomly. I re-saved the same entities, and they appeared in the index again. I have no idea if other entities are missing from the index, because I only know if someone reports it, which is sad and a bit scary. Question is: in which cases can this happen? Which tricks can we use to check/ensure that an index is complete? thanks, rodrigo --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: https support
Hi repairman, Redirects are not required in order to serve traffic from your own domain. You can simply set up Google Apps on your domain (for free), and use that to map a subdomain (for example, www.abc.com) to your App Engine app. Naked domains (abc.com) are not currently supported, but that will not impact your search engine rankings if you ensure your authoritative domain is the qualified (www.abc.com) one and people link to that. You can use your registrar's redirect service to send requests for abc.com/* to www.abc.com/*for manually entered links. http://code.google.com/appengine/articles/domains.html -Nick Johnson On Sat, Aug 22, 2009 at 6:03 AM, repairman alau2...@gmail.com wrote: google guys, I don't know if you guys realize the implication of not getting a static IP? if I have a domain (abc.com) I cannot map it to the appspot subdomain without an IP and I have to resort to a redirect.

[google-appengine] Re: Clean way to code around timeouts?
You can make it into a decorator which will make it easier for your functions to code. I use this: def retry_on_timeout(retries=3, secs=1): A decorator to retry a given function performing db operations. def _decorator(func): def _wrapper(*args, **kwds): tries = 0 while True: try: tries += 1 return func(*args, **kwds) except db.Timeout, e: logging.debug(e) if tries retries: raise e else: wait_secs = secs * tries ** 2 logging.warning(Retrying function %r in %d secs % (func, wait_secs)) time.sleep(wait_secs) return _wrapper return _decorator On Mon, Aug 24, 2009 at 1:53 PM, Bemmu bemmu@gmail.com wrote: I decided to finally do something about the Timeout exceptions littering my log.

Hi Jal, Jesse, A correction: The storage quota is not a daily quota.

You can't, unless you use a reverse proxy in front of the dev_appserver. The dev_appserver isn't designed for this sort of deployment scenario - it's supposed to be used entirely for local development - so even if you can block the /_ah URLs, I wouldn't recommend this approach. If you want to deploy locally, you might want to look into alternatives like TwistedAE or AppScale. -Nick Johnson Thanks!

[google-appengine] jdo - collection element type has not been specified - generics
I'm getting the following error using DataNucleus with Google App
Engine:
org.datanucleus.metadata.InvalidMetaDataException: Field test in
class Wrapper has been defined as a Collection but the element type
has not been specified!
It seems DataNucleus doesn't figure out the collection type when the
type is specified in the declaration of a class.
For example, the following fails with an InvalidMetaDataException as
noted above...
public class Wrapper {
...
@Persistent
private Test test;
...
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Test extends ArrayListString {
...
}
Is there a way to change my annotations so that DataNucleus will
accept my type declaration, or do I have to change my code?
I posted this to the DataNucleus forum on Aug. 13 but haven't heard a
peep.
Thanks for any help,
Peter

One of the key requirements to use GAE for enterprise applications is to document and test all aspects of security.

Often a SAS70 type-2 audit or PCI compliance statement is required.

[google-appengine] Re: deserialize xml
Hi veearrsix,
Like vp mentioned above, the fastest way to query flickr is to use
their json api,
Below is some code that I use in one of my Google Wave Robots to do
such a thing, hope it helps.
The code was given in the Robots group and is not mine, but it does
work.
[code]
def searchFlickr(query):
results = []
url = 'http://api.flickr.com/services/rest/?
method=flickr.photos.searchapi_key=13b98c74bedac9150a428e87bc782e81format=jsonper_page=5text=
%s' % (urllib.quote(query))
content = urlfetch.fetch(url=url).content
content =content[:-1].replace(jsonFlickrApi(,)
for item in simplejson.loads(content)['photos']['photo']:
results.append('http://farm'+str(item['farm'])
+'.static.flickr.com/'+str(item['server'])+'/'+str(item['id'])+'_'+str
(item['secret'])+'_m.jpg')
return results
[/code]
Note, you will need a simplejson, urlfetch and urllib imports in order
for it to work.
Regards
Anthoni

[google-appengine] renaming / destroying an appengine ?
hi, i know it's pretty impossible to delete an appengine app once you've created one, but is there any way to rename it (the application identifier) ? also is there any way to change the Authenticiation Options after you create it ?

[google-appengine] javax.jdo.JDOUserException: Transient instances cant be deleted.
Hi all,
I am new at Google Technologies. The first sample I have been trying
to develop is Flex Remoting with Google App Engine. While inserting
and listing there is no error, but when I try to delete or update a
database object I am facing with the exception below:
javax.jdo.JDOUserException: Transient instances cant be deleted.
The entity I use in the sample is below:
package com.hymelanos.data.entity;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
@PersistenceCapable
public class Product {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
Long id;
@Persistent
private String name;
public Product() {
}
public Product(Long id) {
setId(id);
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
The service implementation's delete method is below:
package com.hymelanos.service.product;
import java.util.List;
import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManager;
import javax.jdo.PersistenceManagerFactory;
import javax.jdo.annotations.Transactional;
import com.hymelanos.data.entity.Product;
public class ProductOperationsImpl implements ProductOperations {
// persistance manager
private static final PersistenceManagerFactory pmfInstance = JDOHelper
.getPersistenceManagerFactory(transactions-optional);
PersistenceManager persistenceManager;
// other methos are here
// -
@Override
@Transactional
public boolean deleteEntity(Long id) {
// get persistance manager
persistenceManager = pmfInstance.getPersistenceManager();
try {
persistenceManager.deletePersistent(new Product(id));
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
}
And the full exception is below:

[google-appengine] Re: https support
repairman, I'm building what I hope will be a real business on GAE. In particular, my system design is not possible in environments like EC2, because of the extra configuration and overhead involved in holding a static IP. That was a design decision by Amazon. Not having a static IP was a design decision by Google, and it offers a different set of advantages. If there were only a few different kinds of things on the planet that we could eat, we would have no chefs. When creating a great dining experience for your customers you need a variety of ingredients to put together that 5 star dish. My hat is off to the GAE team for carefully considering their design implications. I hope they continue to keep their ear to the crowd, but hold their ground to offer the ingredients we need to make great products, rather than just anything that everyone else has. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: synthentic keys - performance implications?
thanks - I got bit by those __init__ nuances over the weekend. I ended up passing an optional flag to the __init__ to say this is really a new() vs a datastore reconstitution. I del the optional flag from kwargs before calling the super __init__. In the datastore reconstitution case, I do nothing but call the super __init__. Does that cover the __init__ gotchas, or am I digging my own grave by not converting to a distinct create function?

Not really, no. 2) If no, are there any other environmental factors that might be fodder for the hash (user, etc)? I would recommend using uuid.uuid4().hex instead of a straight SHA1 sum. UUIDs are guaranteed to be unique. I would also recommend defining a class method called something like 'create' that generates the key name and calls __init__. There are subtle-use cases around __init__ and reconstructing entities from the datastore, and it's difficult to get right - much more straightforward to define a class method to construct new entities. -Nick Johnson Thanks, Jeff -- Nick Johnson, Developer Programs Engineer, App Engine --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Question on increasing performance..
If you only want the 3rd object, do you think it's faster -- Just do a normal fetch(3) -- Do a keys_only fetch(3), then a get of the 3rd key? On Aug 23, 4:41 pm, djidjadji djidja...@gmail.com wrote: Your query will probably fetch more then 25 Action objects. Fetching all those Keys is fast. Fetching all the complete objects is slow, you fetch a lot more then you need. If you iterate over the GQL query, no fetch, that requests full Action objects (SELECT * FROM ACTION...), the objects will be fetched in batches of 20. You then only fetch a few more objects then needed. Performing XX_multi operations on the memcache will also help reduce the response time. 2009/8/23 bvelasquez bvelasq...@gmail.com: http://pastie.org/592489 If you can help me answer this question, I would appreciate it. The above code takes the following ~ time: 1370ms 1725cpu_ms 670api_cpu_ms. Changing the query to return the Actions bumps it up to : 2311ms 3050cpu_ms 1018api_cpu_ms Changing the Action.get() to use the list of Keys from the SELECT takes ~ 2000cpu_ms. I was surprised that doing an individual get on each key was faster than passing the array into get or returning the actions with the query. What are your suggestions for optimizing this, if anything is obviously wrong or maybe there is another way completely for achieving the same results, which my limited experience is not telling me. A couple notes. Project is a ReferenceProperty in Action. I'm getting the key and pulling that from memcache if it is available. I'm breaking on count = 25 because I only want 25 results where the Actions project is active and not deleted. I cannot limit the fetch on 25 because those 25 might be in an inactive Project.

[google-appengine] Re: Question on increasing performance..
If it is about response time I think the normal-fetch(3) is faster. Only one call to the datastore, objects are fetched and converted to python-objects in parallel. If you also want to optimize the CPU-ms it depends on the size of the objects. Writing a test is the only way to know for your type of objects. 2009/8/24 Devel63 danstic...@gmail.com: If you only want the 3rd object, do you think it's faster -- Just do a normal fetch(3) -- Do a keys_only fetch(3), then a get of the 3rd key? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Why am I getting a regular Timeout?
Hi all,
I have an incredibly simple query that looks like this:
listings = Listing.all().filter(created =, str(now)).order('-
created')[:10]
Currently, it is looking through about 12 records (and returning up to
10), now is a datetime. This regularly times out! How can such a
simple query with almost no data to look through timeout regularly
(like 50% of the time)?
I thought maybe it was because I didn't create an index for the
descending situation. So I added this to index.yaml:
- kind: Listing
properties:
- name: created
direction: desc
But, during upload, I am told this:
Error 400: --- begin server output ---
Creating a composite index failed: This index:
entity_type: Listing
ancestor: false
Property {
name: created
direction: 2
}
is not necessary, since single-property indices are built in. Please
remove it from your index file and upgrade to the latest version of
the SDK, if you haven't already.
Any ideas?

Every operation to the datastore has a chance to timeout. You should retry
datastore operations.

[google-appengine] First __key__?
It would make my paging code a lot cleaner if there were a way to indicate 'the first key'. Is there? Like db.Key.from_path (MyModel.kind(), ) when using key_names? That way, I could compile my GQL and just keep plugging in a new :key value each iteration, including the first. I know, the example cases always look clean with their starting query, and then the follow-ups, but in real life I sometimes find myself pretty nested with various logic clauses such that it would be nice to just be able to do this. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
