Django :: Pyamf Register Class Not Mapping Strongly Typed Objects As Expected
Nov 15, 2011
I'm using Pyamf as my backend for my Flex app and I'm seeing some weird problems with the mapping of the stongly typed classes.[code]When I do that in Flex, I get my SouvenirAct objects are typed as they should be, BUT then the child souvenir objects are all null. So when I force the casting of the SouvenirAct objects in the return result, I get null for the child properties that are strongly typed.Has anyone see this before? Is there a different way I should be mapping classes?

So is
public var user:Object = {};
user["firstName"] = "Bill";
user["lastName"] = "Cosby";
Slower than if I have a value object like User?
var user:User = new User();
user.firstName = "Bill";
user.lastName = "Cosby";

How would I create a strongly typed class at runtime (so to be able to create instances of it)? It can't be a proxy.
Additional Info: For example, say I want to create a Person class with first and last where both are Strings.
Context This is for an application that lets you create the data model and custom components at runtime. This is only part of it. I need to be able to have strong typing. If that means going to the server and creating a new SWF on the server with the value objects then loading in the definition at runtime then I would but that is a lot more work if there is an alternative.

For example, using my UserProfile model:
class UserProfile(models.Model):
user = models.ForeignKey( User, unique=True )
blurb = models.CharField( max_length=200, null=True, blank=True )

Is there a way i can Loop through the attributes of a strongly typed Object or just convert a strongly typed Object into a generic Object.I tried typecasting a Strongly typed object created using LCDS into a Object.But it just returned me a typed Object.

I'm running into difficulty passing a strongly typed object, AttractView, to another method, addView() which expects an IWizardView interface that AttractView does implement. When I pass it as-is (as shown below), I get the compile error CaptureApplication.as, Line 120 1067: Implicit coercion of a value of type AttractView to an unrelated type IWizardView. Casting to either IWizardView or BaseView before passing yields a similar error at run time.

I'm using Zend AMF to send my remote objects to Flex. I've defined a Constant class and created getASClassName() method. Then I've created Action script class in flex.
Objects are send successfully, but they are deserialized to generic Objects in Flex instead of specific ones. EDIT: On network monitor in Flex I can see that AMF value is set to com.my.project.valueobjects.Constant. Although array from event.result contains Objects.

(This is the first time I've done this actually.)
<mx:HTTPService id="post_update" method="POST" result="{Dumper.info('bye')}"/>
The result handler above is just for debugging purposes, but its never hit, even though what I'm uploading via POST..

I am creating a django-based site that will serve flash apps that occasionally access data via pyamf. I need to be able to easily test the flash in the context of the django framework, i.e. with all the login cookies and everything available, so that when I make a pyamf call, it has all the user context there. And I need to be able to test and release both the swf's and the wrapper html's in a sane way. However:
The html templates in flex are already templates, so if I put template code in there for django, it gets scraped out before the flashapp.html is created. The html's and swf's automatically get released to the same directory, but I want them to go to different directories because the swf's shouldn't be served by django and the html's should be in an area in control of django.

I have some audio data in a byte array in a Flex app that I would like to save to my model in Django. I assume I would use a FileField, but I can't seem to get it to work. (My project is set up like this.) I've tried looking at this sample code for PyAmf, but I can't quite get the two to combine.

Unfortunatly im having to extend to more draggable objects. So they will be within another movie clip so i can have them scrolling. After making the scroll, the draggable objects dont register on the droptarget as they are within another movie clip. Below is i think the part of the code that needs to be changed so the draggable objects know where to find the drop target.

If I've got a bunch of plain old Objects, what's the best way to map them to a bunch of Classes?For example, if I use an HTTPService to pull in some JSON, then deserialize it, I'll have a bunch of objects which look like:
{ type: "person",
id: 42,
name: "David" }
And I want to turn them into instances of a Person class:
class Person {
id:int;
name:String;
}
(also to be considered: how about some standard way of dealing with relationships between objects? For example, if the Person had an additional "spouse" field:
{ type: "person", spouse: 61, ... } // Where 61 is the ID of the spouse
)

I have 2 java classes that are the same (imagine the getters and setters):
class ScheduledEvent {
private String eventName;
private List<eventValues> values; [code]....
Now there is a reason why there are two classes that are the same.When something is "scheduled", I should get the ScheduleEvent object and when an event is started, I should get the StartEvent object.And depending on the object I get back, I do different things.My problem is that, on the backend, it will send me the ScheduleEvent object, but once it got to the flex side (via BlazeDS), it becomes a StartEvent....
At first, I thought it's because these two events have exactly the same variables, so I tried changing ScheduledEvent by adding a dummy variable (String foobar) but that didn't seem to make a difference.
EDIT: I'm using BlazeDS messaging system.That's why I am not using "one java method call to one responder" approach. So, in the message.body, I should be getting ScheduledEvent but I keep receiving StartEvent. I'm wondering if it's because the two objects have the same property and BlazeDS doesn't know how to map them correctly... I even put a break point in the java service layer, to make sure that the appropriate object is being sent back and it is... But by the time BlazeDS serializes and deserializes it to the flex side, it is now a StartEvent.

For example in Java you can do:List<Person> where Person is the object type.In AS3/FlexArrayCollection which takes any object type. Is there any way to create a list/collection of declared objects in AS3/Flex (or is it impossible due to weakly typed language)?

I succeeded in sending typed objects from a PHP application to a flex front-end using Zend_AMF as per this question. The problem I am facing now is that I would like to send a typed object from flex to PHP and on the PHP side, be able to receive it as a typed object instead of stdClass.
Here is the class in flex:
package com.mysite{
[Bindable]
[RemoteClass(alias="CTest")]
public class CTest {
public var stuff1:String;
[Code] .....
After some testing, I removed the namespace from the PHP object and moved it into the global namespace. This seems to have resolved the issue. I have tried setting RemoteClass to modules estingCTest and also modules.testing.CTest. $_eplicitType was then set to the same value for both tests. The result is that when I use modules.testing.CTest, this is the classname that Zend_AMF sees. If I use namespace notation, Zend_AMF sees modulestestingCTest, as all the slashes get stripped out. But how can I get this working with php namespaces?

I'm building from scratch a web application that is not trivial (have some algorithms and calculations in the backend) but not too complex (it doesn't have to process lots of records during runtime. We thought about using Django for the backend in order to be able to develop the application fast with flex based GUI.
I'm a Java developer with no experience with Django so basically I wanted to know if using Flex and Django together is a good option in terms of ease of development and maintenance? I saw that there are several libraries such as pyAMF and DjangoAMF for this purpose, but since Django is also about html templates and MVC, does flex really work well with django?

Is it possible to receive custom generic typed objects through AMF? I'm trying to integrate a flex app with an existing C# service but flex is choking on custom generic typed objects. As far as I can tell Flex doesn't even support generics, but I'd like to be able to even just read in the object and cast its members as necessary. I basically just want flex to ignore the <T>. I'm hopeful that there's a way to do this, since flex doesn't complain about typed collections (a server call returning List works fine and flex converts it to an ArrayCollection just like an un-typed List).
The custom C# typed class
public class TypeTest<T> {
public T value {
get; set; }
public TypeTest () {
}}
The server method returning the typeTest
public TypeTest<String> doTypeTest() {
TypeTest<String> theTester = new TypeTest<String>("grrrr");
return theTester;
[Code] .....
Irritatingly if I change the result handler to take parameter of type Object it works fine. How to make this work with the value object?

Is the same possible in ColdFusion? Currently I am using .Net/Fluorine to return objects to the client. Whilst in testing I like to pass strings representing the select statement and the custom object I wish to have returned from my service. Fluorine has a class ASObject to which you can set the var 'typeName'; which works great.
I am hoping that this is possible in Coldfusion. Does anyone know whether you can set the type of the returned object in a similar way. This is especially helpful with large collections as the flash player will convert them to a local object of the same name thus saving interating over the collection to convert the objects to a particular custom object.

Dear goodness, am I the only person on the web trying to send a VO object from Flash to AMF where the properties are read only/getters? If I add a setter that does nothing but throws an Error it works. If no setting is present in Flash, it fails. Is there a way to send objects to AMF that have getters and not setters?

can you declare multiple classes and then register each movieclip from the library to a different class? It isnt working for me.I created two different classes and created two entire different movieClips and registered each movie clips to a different class.However, I can only use on movieClip at a time, when I use the duplicateMovieClip... command to create copies of the movieclip, i find that only those movieclips, whose class i declared first, appear on stage.

I'm working on a website using :
- Flex 3.4
- AMFPHP 1.9b
- Propel 1.3
- PHP/MySQL
I'll try to focus on the problem which takes place in a whole system.To sum up, I have 2 entities (MySQL) :
create table AAA
(
id_AAA int not null auto_increment,
id_BBB int,
[code]....
I retrieve all my BBB, they are mapped from PHP classes (generated by Propel) to AS3 classes on the Flex side.But when I create a AAA row in the database.I retrieve all my BBB, and all objects are mapped EXCEPT the BBB whose id corresponds to the foreign key in the inserted AAA row.
if you know anything about how AMFPHP / Propel / Flex are dealing with Foreign Keys and why class mapping is failing right here.The weird thing is that it seems to happen only for this specific case ...

example:
var c : Class = Sprite;
//This can be random class such as movieclip/etc
var o = getDefintionByName(getQualifiedClassName(c));
this works, but in flash develop, it says that the variable 'o' has no type declaration
which basically means
var o : SOMETHING = getDefintionByName(getQualifiedClassName(c));
but how do i put that something there when i do not know what its coming because of random classes?

I am currently migrating from RubyAMF to PyAMF. In RubyAMF you can return a FaultObject deliberately like so:
render :amf => FaultObject.new("Thats not your pie!")
Is there comparable functionality in PyAMF? I've searched the docs and can't find any mention of it.

Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
