 Hi saintthor,

 App IDs are unique, hence you won't be able to reuse the old one after 
 (for example) app deletion. For MS - HRD migrations app alias is created 
 automatically after the completion of step 11 of [1]. Alias means that your 
 new app id will be serving when the customer requests your app with an old 
 app id. Should there be any issue with alias creation, please let us know 
 by leaving your old and new app ids.

 Best regards,

 Nikita

 I just deployed a little test app. It is under quota so I don't think 
 appstats is reporting that for me.

 However, the important thing to note in this context is that whether I use 
 the db api or ndb, it is the same datastore operation ... which is a query 
 in this case.

 If you still need proof, I suggest you write your own test application. 
 As Vinny suggested, you can post that and there might be some more 
 discussion to come from it.

[google-appengine] Re: ndb, get_by_id can not get an entity with a parent key only by id?

hi, are you a google guy?

what do you think the real usage of the key group ( or tree ) is?

for example, a forum, user entity and article entity, i set article.author 
to user entity, then how can i get all articles for a user? in db, i can 
set it with referenceproperty and get a _set ended property in user entity. 
in ndb, i have to use query to do this?

 I've also tested utilizing parent's recently, don't remember the exact 
 reason

 I've found out that you can't get an entity only by id, if it has a 
 parent, you have to know the parent too, that's why I utilized a different 
 method to achieve whatever I was after at that time (don't remember)

 I also like to simply get entities by their id's - so I almost never give 
 them parent's

 I would suggest not utilizing parent's unless you exactly know what you 
 are doing

 I suspect you are learning ndb, I would suggest reading 
 https://developers.google.com/appengine/docs/python/ndb*/ *fully

 AppEngine documentations are really easy to read and pretty fun, it 
 shouldn't take 3 hours to grasp all concepts related to ndb

[google-appengine] what is the best way to store entities with relations in ndb?

for example,  there are two models, author and article.

author1 writes article1 and article2.
author2 writes article3 and article4.

features: find the author of a article. find all articles written by an 
author.

in db, i set a referenceproperty named auth in article model. link it to 
author. in author, use auth_set to find the articles.

in ndb, how to store this relation to make author and article find each 
other without querying?

[google-appengine] Re: ndb, get_by_id can not get an entity with a parent key only by id?

in db, i set such a property in model article:

 auth = db.ReferenceProperty( author, collection_name=AuthSet )


and use author.AuthSet to get all articles written by the certain author. 
there is no query. how can i do the same thing in ndb?


在 2014年7月22日星期二UTC+8上午3时55分28秒，Jay写道：

 Responding to your first post ... that is right. The parent key is part of 
 the entity's key. When you use get_by_id, this is just shorthand for 
 Key('Foo', 99).get().
 You cannot get an entity by key unless you know the key, the whole key. 

 You say you don't want to query, but your use case ... give me all 
 articles for user A ... sounds like a query. 
 articles = Article.query(Article.author == user_key)...

 If you want to do something like most recent n articles then you can 
 store those keys in a 'secondary index' of sorts and use ndb.get_multi()

 There are online virus-scanning tools you can use via API such as: 
 https://scanii.com/ and 
 https://www.virustotal.com/en/documentation/public-api/ . Alternately you 
 can use a Compute Engine 
 machinehttps://cloud.google.com/products/compute-engine/
 /Managed VM https://developers.google.com/cloud/managed-vms, install an 
 anti-virus scanning engine, then run all your uploaded files through there.

 If you don't want to handle virus scanning yourself, you could try 
 requiring users to upload files from a trusted source. For example, Google 
 Drive virus scans files under 
 25MBhttps://support.google.com/a/answer/172541?hl=en- you could have users 
 upload to GDrive, then select files using the Drive 
 API https://developers.google.com/drive/v2/reference/.

 An F1 instance gives your application 128 MB of memory. If you application 
 only uses 70 MB, the remaining memory remains unused but still accessible 
 by your application.

 If you launch a second instance, your application gets a separate instance 
 with a separate allocation of memory. There isn't any memory sharing 
 between instances, if that's what you're asking.

 From your recent questions, I get the impression you have a specific

 I suggest taking a step back, thinking about your business goals, and see

 on GAE requires a mental shift from how you have probably developed 
 server-side apps in the past. While there are certainly edge cases, most

 It depends how your application is architected and what your exact needs 
 are. For example, you can have the frontend instance put the data into a 
 task and return immediately. Then have a backend lease the tasks off a pull 
 queue and process them.

 If the processing isn't time-sensitive (doesn't need to be processed 
 immediately), you can record the data into the datastore and process it at 
 a later time.

Does your log look like this: http://imgur.com/uePke5W ?

If so, then something in your web pages is requesting that file, and App
Engine can't find it within your application. Specifically, a *min.map*file
is a sourcemap: someone is looking at your web pages with Chrome's
developer tools or similar. You can find the map file and place it in your
application, see the details of how to do this
herehttp://stackoverflow.com/questions/18365315/jquerys-jquery-1-10-2-min-map-is-triggering-a-404-not-found.

Note this: Normal users will not need the sourcemap data, it's only needed
for debugging JS code via development tools.

[google-appengine] how to limit 1 instance for my app?

2014-04-25 Thread saintthor

i use app caching to cache data. if there are many instances, the data 
won't be found.

i want to limit the instance num only one. if there are more requests, let 
it wait or fail.

or, can i detect the instance num in code and shut down the more?

[google-appengine] how to use Background_threads?

https://developers.google.com/appengine/docs/python/modules/#Python_Background_threads

i copy the code, run and get FrontendsNotSupported.

i want to input some data in a request and then return. let the backend(?) 
analyse the data after returning. so i use Background_threads. right?

is there anyway else to do my job?

 This might be a good feature to ask for but for now you have to enforce it

 if i put many entities in 1 second with method put or put_async, will it 
 raise exceptions?




 It won't necessarily raise an exception (it might, not guaranteed) - but 
 it does lead to inconsistent behavior. Best not to even try it, especially 
 if your data is important to you.

[google-appengine] there may be something wrong with put_async

model.put_async()

then return. without calling Future.get_result(). shouldn't the model be 
written to datastore?
