Question

问题在于：

我请求一个对象，它将从远程服务器获取并持久保存到dataBase没有问题。我是这样做的：

我已经定义了一条路线：

+ (RKRoute *)getRestMenuRoute
{
    return [RKRoute routeWithRelationshipName:@"rest_menu" objectClass:[Restaurant class] pathPattern:@"menu/:restaurantID" method:RKRequestMethodGET];
}

- (void)LoadRestaurantMenu:(Restaurant *)resturant withCompletionBlock:(completion)completionBlock
{

    [self getObjectsAtPathForRelationship:@"rest_menu" ofObject:resturant parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
        completionBlock(YES, nil);
    }
    failure: ^(RKObjectRequestOperation *operation, NSError *error)
     {
         //creating a new error which contains HTTP status code
     }];
}

self是RKObjectManager

的子类

MenuMappingProvider：

RKEntityMapping *menuMapping = [RKEntityMapping mappingForEntityForName:@"Menu" inManagedObjectStore:managedObjectStore];
    menuMapping.identificationAttributes = @[@"menuID"];

    [menuMapping addAttributeMappingsFromDictionary:@{
                                                            @"Setting.MinOrder":@"minOrder" and more .....
                                                            }];

    NSDictionary *restaurantIDMapping = @{@"@metadata.routing.parameters.restaurantID": @"restaurantID"};
    [menuMapping addAttributeMappingsFromDictionary:restaurantIDMapping];
    [menuMapping addConnectionForRelationship:@"restaurant" connectedBy:@{@"restaurantID":@"restaurantID"}];

但是当我发送批量请求时，restKit会记录对象检索和映射成功，但是当我查询餐馆菜单时，它会记录nil！没有对象已保存到dataBase。

这是我的批量请求：

- (void)syncRestaurantsMenuWithProgressCallBack:(progressCallback)progressCallBack
{
    [self enqueueBatchOfObjectRequestOperationsWithRoute:[HARouter getRestMenuRoute] objects:[Restaurant findAll] progress:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {

        CGFloat progress = (CGFloat)numberOfFinishedOperations/(CGFloat)totalNumberOfOperations;
        progressCallBack(progress);
        NSLog(@"sync menu progress:%f", progress);
    } completion:^(NSArray *operations) {
        NSLog(@"all menus synced!");
    }];
}

每个获取对象的RestKit日志：

restkit.network:RKObjectRequestOperation.m:222 GET 'https://restaurant.com/menu/2176' (200 OK / 1 objects) [request=4.3484s mapping=0.0048s total=4.3588s]

你的想法是什么？你怎么看？我的问题是什么？

更新

当我批量排队时，从restaurant实体到Menu实体的Restaurant关系将无法建立！我在名为Menu的{{1}}实体中定义了一个外键，并使用此外键建立从restaurantID到Menu的连接。 RestKit将从路径元数据中设置此外键，然后检查餐馆列表以找到具有相同Id的餐馆，然后建立从菜单到餐馆的连接，反之亦然。

RestKit CoreData跟踪日志：

Restaurant

更新2

首先我获得餐馆列表，他们的基本信息，然后在完成块中我获取菜单。关系是一个2一。因此，关系是一个2 1这是否可以在映射中为2015-12-07 14:11:47.290 MyApp[28491:16381752] T restkit.core_data:RKRelationshipConnectionOperation.m:193 Connecting relationship 'restaurant' with mapping: <RKForeignKeyConnectionDescription:0x7fe3715b4c20 connecting Relationship 'restaurant' from Entity 'Menu' to Destination Entity 'Restaurant' with attributes={ restaurantID = restaurantID; }> 2015-12-07 14:11:47.290 MyApp[28491:16381752] D restkit.core_data:RKRelationshipConnectionOperation.m:204 Connected relationship 'restaurant' to object '(null)'实体提供identificationAttribute？
