A simplistic json-rpc dispatcher-function for Django in 15 lines

def JSON_RPC_dispatcher(obj):
      rpc_inputs = json.loads(obj.raw_post_data)
      sub_eval = str(rpc_inputs['method']) + '(rpc_inputs["params"])'
      if rpc_inputs['method'] in jsonrpc_methods:
         result = eval(sub_eval)
         json_retur = json.dumps({'result': result['result'], 'error': result['error'], 'id': rpc_inputs['id']})
         response = HttpResponse(json_retur)
         response.__setitem__('Content-Type', 'application/json-rpc')
         return response
      else:
         json_retur = json.dumps({'result': None, 'error': '<non_existent_method_mesg>', 'id': rpc_inputs['id']})
         response = HttpResponse(json_retur)

This function works as a decoding/encoding dispatcher between Django's HttpRequest-object and arbitrary defined method-functions of the json-rpc service. Those method-functions shall return a dictionary-object as {'result': <result_data>, 'error': <error_data>} and their names shall be appended/registered to the jsonrpc_methods list. This dispatcher-function is generally suitable for any json-rpc app and neutral to the exact version of the json-rpc protocol in consideration.
