Meine Implementierung sendet keine Parameter. Hier ist der RequestDescriptor:

RKObjectMapping *userMapping = [RKObjectMapping requestMapping];
[userMapping addAttributeMappingsFromArray:@[@"nombres", @"telefono", @"direccion", @"email", @"identificacion", @"tipo_id", @"recibir_sms_ordenes", @"recibir_correos_ordenes"]];
RKRequestDescriptor *descriptor = [RKRequestDescriptor requestDescriptorWithMapping:userMapping objectClass:[RKUser class] rootKeyPath:@"me" method:RKRequestMethodAny];
[[RKObjectManager sharedManager] addRequestDescriptor:descriptor];

Hier ist die Postanfrage:

RKUser *user = [self currentUser].user;     // [self currentUser].user returns the current RKUser
RKObjectManager *manager = [RKObjectManager sharedManager];
[manager postObject:user path:@"/api/me.json" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
  NSLog(@"%@ %@", operation, mappingResult);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
  NSLog(@"%@ %@", error, operation);
}];

Auf dem Server erhalte ich nur eine leerecurrent_user Parameter. Irgendwelche Ideen warum?

PD. Der Server erwartet JSON-Payload unterme Schlüssel
