Sorry for digging up this thread but I fell off the list a bit and
just checked back today.
I really like the Pyjamas jsonprc implementation. In fact, I like it
so much I've gone ahead and modified a few things to do the SMD
generation and service URL resolution. However, I have a problem with
my approach.
This is how I modified JSONRPCServiceBase.__init__:
def __init__(self, url):
self.methods = {}
self.smd = {
"serviceType": "JSON-RPC",
"serviceURL": url,
"methods": []
}
Notice that I added the 'url' param and the smd skeleton (no methods
yet)
I then added the method 'get_smd()' to JSONRPCServiceBase:
def get_smd(self):
import inspect
for method in self.listmethods():
sig = inspect.getargspec(self.methods[method])
self.smd["methods"].append({
"name": method,
"parameters": [ {"name": val} for val in sig.args ]
})
return simplejson.dumps(self.smd)
Then I fixed up JSONRPCService.__call__:
def __call__(self, request, extra=None):
if request.method == "POST":
return HttpResponse(self.process(request),
mimetype="application/javascript")
else:
return HttpResponse(self.get_smd(),
mimetype="application/javascript")
Use it like so:
from jsonrpc import JSONRPCService, jsonremote
chatservice = JSONRPCService("/chat/")
@jsonremote(chatservice):
def send_message(request, message):
do something ...
Having GET requests return the SMD allows client apps to resolve the
methods before calling them so you don't have to use a str-ified
version:
var chat_service = new dojo.rpc.JsonService("/chat/");
chat_service.send_message("Hello World!").addCallback(function
(response) { console.log(response); });
vs:
var chat_service = new dojo.rpc.JsonService();
chat_service.serviceUrl = "/chat/";
chat_service.callRemote("send_message", ["Hello World"]).addCallback
(function(response) { console.log(response); });
Now the problem ... I can't get URL reversing to work when first
setting up the service:
from jsonrpc import JSONRPCService, jsonremote
chatservice = JSONRPCService( reverse("chat-rpc") )
Urlconf:
url(r"^chat/$",
"myproj.myapp.views.chatservice",
name="chat-rpc",
),
ViewDoesNotExist: Tried chatservice in module myproj.myapp.views.
Error was: 'module' object has no attribute 'chatservice'
But just sticking "/chat/" in there works great. This has to do with
when the url is actually reversed -- but I can't figure it out.
Any help would be great.
Thanks,
Ben
