[google-appengine] Access to child object key without fetching object (JDO)
Is it possible to fetch the key of a child object without going to the
datastore to fetch that child object? I know I could store the key as a
string in addition to the object, however that seems unnecessary given that
the key must already be stored in the parent object for it to be able to
fetch the child. I am using DataNucleus JDO.
For example,
Server Side Service Code
MyClass myclass = pm.getObjectById(MyClass.class, someKey)
//is the following possible without fetching the childObject from the
datastore
//All I want is the key
myclass.getChildObject().getId()
@PersistenceCapable
class MyClass{
@Persistent
private ChildObject obj;
public ChildObject getChildObject(){
return obj;
}
….
}

[google-appengine] How to upload an image from an Android Client to the datastore and get it back (or send it to another client)?
I've been doing GAE tutorials the entire week and haven't been able to send an image to the datastore using google cloud endpoints and retrieve it (maybe with modifications done serverside). Basically I would like to create an asynchronous multiplayer game using GAE and Android where Person A creates an image, then sends it to the server, server sends it to Person B, who edits the image, and then Person B sends it back to A (and so on). Do you guys have any recommendations on how to go about implementing this? I tried looking at the tictactoe samplehttps://github.com/GoogleCloudPlatform/appengine-endpoints-tictactoe-java to learn more about the relationship between the backend and the android client but I haven't been able to figure out how to do something like I described. Not only that, but the tutorial seems to be all over the place for beginners like me. If they explained that tictactoe sample like they did with the Mobile Assistant Tutorialhttps://cloud.google.com/developers/articles/how-to-build-mobile-app-with-app-engine-backend-tutorial it would be amazing. If any of you have any helpful, very simple functional samples using GAE for android in java relating to this type of problem (image sharing through GAE using Android) it would be extremely helpful.

[google-appengine] Re: ODBC for the Datastore?
I don't think you're going to find anything like that for GAE Data Store; the Data Store is a NoSQL database technology, and ODBC, while technically a very flexible specification that can be adapted to address a wide range of database technologies, really evolved hand-in-hand with SQL databases. The data store and other NoSQL databases don't support a wide range of standard SQL constructs such as JOIN's or SUM/COUNT or any other scan type of operation. It is highly unlikely that an app originally written for a SQL-based database will work with a NoSQL database without major rework. If you're transitioning an existing desktop app over to the cloud, I suggest you look at cloud-based RDBMS offerings such as Google's Cloud SQL offering which is based on MySQL and will offer odbc/jdbc drivers allowing you to point existing code at the cloud-based database. Amazon Web Services also has a nice offering called Relational Data Service (RDS) which supports MySQL, Oracle and MS SQL databases in the cloud, again with traditional driver support.

[google-appengine] Re: How to upload an image from an Android Client to the datastore and get it back (or send it to another client)?
Yes, it's possible to do this with Google App Engine. There are a lot of options; you'll need to make some design decisions to start, and then the documentation can help you with the implementation. First, you need to decide whether the game state should be stored on the server or transient. That determines whether you need to use the data store. Most likely you'll want the game state to be stored, but I don't know your specific requirements so I could be mistaken. Assuming you want to use the data store I *highly* recommend you use Objectify rather than the built-in JPA or JDO support in App Engine. Objectify has a lower start up cost so is better for overall performance, and its APIs are tailored to GAE so you avoid some of the weirdness in JDO/JPA. In addition to the game state it sounds like you want to store images. Storing image data in the data store might not work for you depending on the image size; if that's the case you may want to look into the Blobstore APIs. I have not personally used them so I don't have much to say there. Next, you need to decide how players submit moves, and how they will be informed of moves by other players. Google's documentation suggests using the Channel APIs, which are essentially a wrapper around WebSocket. There are some significant limitations to Channel, though, not least of which is that the client has to be JavaScript (for Android, this means using an embedded WebView). Channel is also designed to be one-way (server to client); for client to server messages Google suggests using HTTP POST requests. An alternative to Channel is to use HTTP requests in both directions: POST for submitting moves, and GET (in a polling sense) to retrieve moves. GET polling can be less friendly to network bandwidth and battery though. In my own (iOS) game I decided to use raw WebSockets instead and create my own wrapper, foregoing the Channel APIs. There are WebSocket libraries for both iOS and Android (though I don't have any experience with the Android ones) - this means your client doesn't have to be a WebView. In addition, WebSocket can be used for bidirectional messaging, meaning you can use one transport for both move submission and notification. However, if you're using the Blobstore to store data, you may want to use HTTP requests to post moves anyway, since (as I understand it) the Blobstore already has an HTTP request interface. Again though, I haven't used Blobstore myself, so YMMV. Finally, a comment on Google cloud endpoints. The cloud endpoints system is not something I've used, but from what I can tell, it is a code generation system designed to make it easier to develop both the client and server together using a single API definition (somewhat like IDL). If that's the case, then there's nothing you can do with cloud endpoints that you couldn't do by hand. I would recommend designing the system by looking at the underlying capabilities of App Engine and seeing which ones meet your needs, and then consider cloud endpoints as a kind of syntactic sugar that can help with the implementation.

Re: [google-appengine] Re: How to upload an image from an Android Client to the datastore and get it back (or send it to another client)?
Keep in mind that GAE datastore entities are limited to 1MB in size, which might be a significant problem for your images. If so, you'll want to use the blobstore/google cloud storage instead and track the metadata in the datastore.

I may re-add PayPal at some point (in addition to Stripe) but it's a pita
to deal with the user leaving your site, processing the ipn notifications,
and then HOPING the user hits the button to return to your site when he's
finished on PayPal. With PayPal there's no guarantee the user will return
to your site (although it's fairly likely). I've also noticed that the
initial redirect to PayPal can take a while (for the page to load). Just
my experience... I'm sure there are others that really like it.

[google-appengine] Joomla CMS and GAE
Yes, I want to store the rule data in configuration.php and then on initialization instead of the hardcoded rules I'm testing with, the rules can be dynamically generated and registered with the wrapper. The only problem I have with that is Joomla won't save arrays of data by default in configuration.php - so it means either a plugin to save the data as an array, or limiting it to X number of rules Indeed configuration.php might be the right place for it. A custom field type could be useful, something that serializes a set rules to json. I think I even have something in place. Let me know and I'll send it over to your repo. I've got some time to work on this again, thanks for your pull requests and fixes. After a lot of thinking, I decided on a somewhat different path. Since GAE allows me to execute PHP code BEFORE the Joomla application, I'm going to replace JConfig with a new class. Instead of saving configuration.php as a PHP file with JConfig class, when executing under Google App Engine JConfig can be a virtual empty class with a large number of static variables[though I have some plans on adding extra functionality]. The configuration data can be saved to Google Datastore and serialized and saved to the memcache server. This will allow us to actually make changes to the Joomla website configuration and have those changes saved out to datastore. With that, I don't need to json encode arrays since they can be stored by serialization. That said, I'd love to add the json form field as well since I should probably create a standard configuration.php file in case someone wants to move a GAE Joomla CMS website to Google Computer Engine. I'm mainly trying to balance my tendency to add in lots and lots of options with keeping things simple so I can get to a release/usable point I mean, why spend weeks adding a bunch of options I don't need if only 2 people are using it? There doesn't seem to be a lot of interest in deploying Joomla to GAE - it's fun for me and it's a good brain teaser to force my mind into a coding gear. I completely agree here. I think more people will get involved once it's fully functional, officially mentioned on the Joomla site and maybe posted on some good blog like http://sitepoint.com Many developers probably don't consider GAE yet as PHP support in GAE is still experimental and there still seem to be many bugs around. My gut feeling is that devs will be using it for really heavy workloads since It really has a big potential as PaaS. Will see, I'm working on getting it to an install point. :-) I've been testing Joomla on Azure recently and would be extremely convinced to stick on it if not the fact MySQL is provided by a 3rd party company with scaling limitations and very harsh limits on free tier for testing (20 MB database !?), bigger options get very expensive. I'm also not really convinced by Windows environment though it's PaaS and I shouldn't care what it is running on. I've run the Joomla! CMS under both IIS and recently on a Windows server running Apache and PHP... I've always run into some odd problems here and there and I just avoid windows in general - having gone so far as to completely switching to Linux[Linux Mint Mate in fact] on all my systems to force myself to stop fiddling around with windows. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Google App Engine Module Instances - separate or not?
If an application is configured with multiple modules, for example I want to have the option to seperate out the admin part of the website from the front end and configure them as seperate modules - if both modules are used at the same time will they use two seperate instances even at low load, or is the decision to start multiple instances based on load? For example, there are a couple of front end ajax functions that, when a super admin is logged on, will poll the admin part of the website for some statistical data. When testing, the load will be low so without modules it would be a single instance. With modules is it forced to run as two instances? -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Processing payments using Paypal, python SDK
The paypal rest api involves receiving credit cards on the server which means they are potentially in logs etc (that with App Engine you don't control). This complicates PCI compliance: *Q: To whom does PCI apply?* *A: *PCI applies to ALL organizations or merchants, regardless of size or number of transactions, that accepts,* transmits* or stores *any cardholder data*. Said another way, if any customer of that organization ever pays the merchant directly using a credit card or debit card, then the PCI DSS requirements apply. *Q: What is defined as ‘cardholder data’?* *A: *Cardholder data is any personally identifiable data associated with a cardholder. This could be an account number, expiration date, name, address, social security number, etc. All personally identifiable information associated with the cardholder that is stored, processed, or transmitted is also considered cardholder data. http://www.pcicomplianceguide.org/pcifaqs.php#2 If someone does achieve PCI compliance with the PayPal rest api and App Engine please document the process so others can benefit from your experience. I personally believe you're better off redirecting to PayPal and back than using PayPal rest.

You'll be amazed at how easy it is to get started AND customers don't have to leave your site! (I'm not associated with Stripe in any way... just using it with App Engine and can attest to its ease of use) I may re-add PayPal at some point (in addition to Stripe) but it's a pita to deal with the user leaving your site, processing the ipn notifications, and then HOPING the user hits the button to return to your site when he's finished on PayPal. With PayPal there's no guarantee the user will return to your site (although it's fairly likely). I've also noticed that the initial redirect to PayPal can take a while (for the page to load). Just my experience... I'm sure there are others that really like it.

Re: [google-appengine] Can't get a module to start via a cron job
Aside from just having the [module name].yaml file in the directory with my default app.yaml file, do I need to do anything else to get the dev_server to recognize the additional module? Make sure you supply all *.yaml files to dev_appserver in cmdline args, e.g.: dev_appserver.py app.yaml module1.yaml module2.yaml dispatch.yaml Execute dev_appserver.py -h for more details.

Try to debug the problem by: 1. Sometimes modules throw up unusual errors when versions are expressed as pure numbers instead of a mix of letters and numbers. In loadandprocess.yaml, change *version: 1* to *version: one*. Remember to update *callLoadAndProcess.py* with the correct version (the *start_module* call). 2. You can use *get_modules()* and *get_versions(module=___)* in the *modules* package to enumerate all the modules and all the versions of a given module that App Engine recognizes within your application. App Engine may be recording the module under a different name or version. - -Vinny P Technology Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Google App Engine Module Instances - separate or not?
On Tue, Jan 7, 2014 at 5:22 PM, Gary Mort garyam...@gmail.com wrote: If an application is configured with multiple modules, for example I want to have the option to seperate out the admin part of the website from the front end and configure them as seperate modules - if both modules are used at the same time will they use two seperate instances even at low load, or is the decision to start multiple instances based on load? For example, there are a couple of front end ajax functions that, when a super admin is logged on, will poll the admin part of the website for some statistical data. When testing, the load will be low so without modules it would be a single instance. With modules is it forced to run as two instances? Unique modules/versions use different instances. Modules can specify different sizes of instances (F1 vs. F4), frontend or backend instances (F1 vs B1), so they need their own instances allocated to them. If you're concerned about high instance usage under low load, you can configure the admin module as a basic scaling instance with a low *idle_timeout* parameter so the instance shuts down quickly when not in use: https://developers.google.com/appengine/docs/python/modules/#Python_Instance_scaling_and_class - -Vinny P Technology Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Configure static file handler/path via app.yaml or dynamically?
With the local SDK, static files have a special handler which can serve their data without requiring the instance to be executing. It strikes me that it would be useful to allow for a redirect handler as well. This would help for static files where you want to store the files in a Google Storage Bucket so they can be updated without requiring a deployment of a new version of the app code, as such I've submitted a feature request for this in 10459. https://code.google.com/p/googleappengine/issues/detail?id=10459https://code.google.com/p/googleappengine/issues/detail?can=2start=0num=100q=colspec=ID%20Type%20Component%20Status%20Stars%20Summary%20Language%20Priority%20Owner%20Loggroupby=sort=id=10459 By extension, it would also be useful to allow for a redirect handler to google storage either dynamically or only if a GS object exists in order to support caching. IE a PHP application could dynamically generate HTML for a page, then save the html to Google Storage under a pre-determined object name and in the future the redirect handler can access that instead: https://code.google.com/p/googleappengine/issues/detail?id=10460 Don't know if others would also like this, so I figured I'd post about the requests here in case there is broader support. -- You received this message because you are subscribed to the Google Groups Google App Engine group.
