Datetime in a callback

[Justin]

Since I'm on such a roll here and have your attention I'm gonna throw one more at you :)

My service is passing a datetime through a callback to the client. The client sees it as a Reference. I played around with it in an interpreter and dug into the python source a little, but haven't seen how to get the datetime value back. I do see methods on the datetime class, but not the value. What am I doing wrong?

Thanks

My simple example:

$ cat server.py

from configit import conf_from_file

from datetime import datetime

config = conf_from_file('../development.py')

from BridgePython import Bridge

class SimpleHandler(object):

    def simple(self, callback=None):

        if callback:

            callback(datetime.now())

bridge = Bridge(api_key=config.private_api_key)

bridge.publish_service('simple', SimpleHandler())

bridge.connect()

$ cat client.py 

from configit import conf_from_file

config = conf_from_file('../development.py')

from BridgePython import Bridge

bridge = Bridge(api_key=config.public_api_key)

client = None

def service_response(resp):

    print(resp)

service = bridge.get_service('simple')

service.simple(service_response)

"""

Prints out:

$ python client.py

<BridgePython.reference.Reference object at 0x10b84f8d0>

Haven't figured out how to get this Reference object to give me the datetime.

Bridge doesn't allow you to use synchronous functions (i.e. those that
return a value), since that would involve waiting for the return
value. Generally, you can either pass the actual value (e.g. UNIX
time) over the wire, or you can provide a wrapper. Yet another option,
since you're working with python => python, is to extend the JSON
encoder/decoder (http://docs.python.org/library/json.html should be
helpful). This last way should allow you to pass Python objects over
the wire and see them as identical (i.e. cloned) objects (as opposed
to remote References).
