I have a JSON RPC API as a set of methods which all have some common processing involved, esp. regarding exceptions. To catch those and in turn raise proper JsonRpcError, with proper code and message, I wanted to wrap the methods in a common decorator.
But then I get "method not found", and if I swap @common_rpc with @jsonrpc_method, of course then params are not identified by pyramid_rpc (MapplyViewMapper).
Am I doing something wrong, perhaps missing to do something with Venusian? Or is it impossible to chain decorators with @jsonrpc_method?
Thanks.

You haven't shown me the signature of your decorator or any errors.
Ignoring that, jsonrpc_method, similar to view_config in pyramid,
supports a `decorator` argument that guarantees you a common signature
for decorators:
def common_rpc(view):
def _wrapped(context, request):
# do stuff with request.rpc_args or whatever else
return view(context, request)
return _wrapped

Ah, I missed to check the docs on config.add_view(). Yeah, the decorator argument now does what I expect of the code.
The error was simple, default pyramid_jsonrpc "method not found" which you get if you call an unregistered method, and the common_rpc() decorator is the following:
