RestKit 0.20.0 を使用して、Devise を実行している RoR バックエンドにログインしようとしています。次のパラメータでリクエストを達成しようとしています:

Parameters: {"password"=>"[FILTERED]", "email"=>"email@mail.com"}

しかし、サーバーで実際に受信されるのは次のとおりです。

Parameters: {"password"=>"[FILTERED]", "email"=>"email@mail.com", "session"=>{"password"=>"[FILTERED]", "email"=>"email@mail.com"}}

このセッション パラメータがどこから来るのか、私にはわかりません。GET を実行するときは追加されず、POST を実行するときにのみ追加されます。ログインは成功しますが、応答は完全に間違っています。パラメータの正しいリストを使用することで、正しい応答が得られます。以下は、リクエストを送信するコードです。このセッションパラメータがどこから来たのかについてのアイデアはありますか?

- (void)loginWithblock:(void (^)(bool))block
{
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:_username, @"email", _password, @"password", nil];
NSString *url = [[MBMSettingsHelper sharedSettingsHelper] authenticationURL];

[[RKObjectManager sharedManager] postObject:nil path:url parameters:params
                                    success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                                        block(YES);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    block(NO);
}];
}

私の appdelegate には、次のマッパーがあります。

// Mappers for authentication
RKObjectMapping *requestMappingForAuthenticate = [RKObjectMapping requestMapping];
[requestMappingForAuthenticate addAttributeMappingsFromDictionary:@{
 @"username" : @"email",
 @"password": @"password"
 }];
RKRequestDescriptor *requestDescriptorForAuthenticate = [RKRequestDescriptor requestDescriptorWithMapping:requestMappingForAuthenticate objectClass:[MBMUserLoginRequest class] rootKeyPath:nil];

RKObjectMapping *responseMappingForAuthenticate = [RKObjectMapping requestMapping];
[responseMappingForAuthenticate addAttributeMappingsFromDictionary:@{
 @"success": @"success",
 @"auth_token": @"token",
 @"email": @"username",
 @"id": @"userId"}];
RKResponseDescriptor *responseDescriptorForAuthenticate = [RKResponseDescriptor responseDescriptorWithMapping:responseMappingForAuthenticate pathPattern:nil keyPath:nil statusCodes:nil];

[objectManager addResponseDescriptor:responseDescriptorForAuthenticate];
[objectManager addRequestDescriptor:requestDescriptorForAuthenticate];

RestKit ログは以下に掲載されています。ログイン後、マッパーがログイン応答を完全に異なるモデル (この場合はボート) にマッピングし始めるように見えますか?

編集 2: 他の RKResponseDescriptors を削除すると、すべてが機能しました。したがって、問題は、マッピングが発生したときに、どういうわけか間違った RKResponseDescriptor が選択されることです...
