set remoting gateway with AMF3

[Horis]

Hello, i began since few weeks to use pyamf. I made an application using a channel and configured pylons with pyamf.remoting.gateway.wsgi (i toke the pyamf example for both).

Everything works but i have no idea where or how to set my application to use AMF3. (to be sure that is AMF3 which is used and not AMF0 when i remote my object).

hope you will understand me and thanks for the answer.

Hi,

I assume you're using Flash as a client.

RemoteObject by default uses AMF3 but you can set the objectEncoding  
directly see [1]

Hth,

Nick

Hi,
when I use PyAMF 0.4.2 with Django I receive following error:
Code Server.Call.Failed is already registered
It seems problem is in the following:
pyamf/__init__.py
in method add_error_class(klass,code). If I comment these lines:
    if code in ERROR_CLASS_MAP.keys():
         raise ValueError('Code %s is already registered' % (code,))
it works.

def add_error_class(klass, code):
     """
     Maps an exception class to a string code. Used to map remoting  
C{onStatus}
     objects to an exception class so that an exception can be built to
     represent that error::

         class AuthenticationError(Exception):
             pass

     An example: C{add_error_class(AuthenticationError, 'Auth.Failed')}

     @type code: C{str}

     @raise TypeError: C{klass} must be a C{class} type.
     @raise TypeError: Error classes must subclass the  
C{__builtin__.Exception} class.
     @raise ValueError: Code is already registered.
     """
     if not isinstance(code, basestring):
         code = str(code)

     if not isinstance(klass, (type, types.ClassType)):
         raise TypeError("klass must be a class type")

     mro = util.get_mro(klass)

     if not Exception in mro:
         raise TypeError('Error classes must subclass the  
__builtin__.Exception class')

     if code in ERROR_CLASS_MAP.keys():
         raise ValueError('Code %s is already registered' % (code,))

     ERROR_CLASS_MAP[code] = klass

Hi,

Is this in a production environment ?

I ask because it sounds like pyamf is being reloaded. If this is the  
case then this is a bug and a ticket should be created.

Cheers,

Nick

Nick,

it's on my development environment.

I have a Django project called 'ABC'. Inside it I copied pyamf  
directory. Structure looks like:

ABC/
   manage.py
   settings.py
   urls.py
   ....
   pyamf/

Than I run python manage.py runserver

When I get an url (it doesn't matter if that url calls code with  
pyamf) I receive the error.

tnx

Piero
