Can we use AsyncHttpClient in Google App Engine application
java,google-app-engine,asynchttpclient
No, you can't. Your options are to use: urlfetch, which is async too Urlconnection which is not, and is pretty low level Apache http client, which is socket based so doesn't use URL fetch Last time I tried to integrate Ning async client on appengine, the issue was it need...
Getting a 411 Length Required error when parameters are very long
java,angularjs,google-app-engine
The params argument you are using is used to pass GET variables as part of the url even when method is POST ($http docs). To pass information in the body of the POST request you have to use the data argument. So, your request should be: $http({ method: 'POST', url:...
Relationships in the Datastore (One-to-Many)
What you have here is a many-to-many relationship as a project has many users and a user may be assigned to many projects (I assume). Using NDB we can try to forget about traditional database relationships and focus on the objects themselves. The simplest way to represent this is to...
Could someone bring Google OAuth2 for Cloud DNS via Rest to light?

GAE webapp2 delete all UserTokens (drop all sessios) for specific user

Here is the code: class MyToken(UserToken): user = ndb.StringProperty(required=True) class MyUser(User): token_model...
App Engine - NDB query with projection requires subproperty?
google-app-engine,gae-datastore,app-engine-ndb,google-app-engine-python
That query is not possible. Unfortunately the exception isn't very clear, but the issue is the result of how sub-properties are actually stored. ndb explodes your StructuredProperty so that each value is included separately. So, for example, the entity: Contact(name="Bob", addresses=[ Address(type="Work", city="San Francisco"), Address(type="Home", city="New York")]) This will get...

html,python-2.7,google-app-engine,gae-datastore,jinja2
Looks like you're being victim of Eventual Consistency: Consistency in the context of the GAE datastore, and in very simple, non-technical, terms, is 'availability of the latest copy of the data'. Perhaps a more intutive (but blatantly incorrect) definition would be the 'lack of lag between writes and reads'. Strongly...

Seperating PHP and HTML [closed]
It is perfectly fine to place your PHP code in the same file as your HTML code. However, if you are going to duplicate code, it would be best to have separate files (maybe say a header and footer file). That way you can use require_once("header.php") and require_once("footer.php") in each...
Python decimal.Decimal id not the same
python,json,google-app-engine,decimal
It appears that the decimal.Decimal class is patched somewhere in the Google App Engine SDK (or the module is reloaded), and this is done between the MySQL conversion library importing decimal and you importing the same. Luckily, we can work around this by updating MySQL conversion table: from MySQLdb.constants import...

GAE DOMDocument::load(): I/O warning : failed to load external entity
javascript,php,json,google-app-engine
For security reason GAE disables external XML entity loading by default (See https://cloud.google.com/appengine/docs/php/#PHP_Functions_that_may_be_manually_enabled for more details). You'll need to call libxml_disable_entity_loader(false) before loading the XML.
GAE/Python best practice for a pop-up alert?

In Google App Engine for Go, how can a property have values of more than one type?
google-app-engine,go,gae-datastore
You do not necessarily have to declare a specific type for a property in a backing struct. By implementing the PropertyLoadSaver interface, you can dynamically do whatever you want with the properties of an entity during loading or before saving. See this answer which shows how to represent an entity...
Cloud Endpoints is REST or RPC style technology?
google-app-engine,google-cloud-endpoints
