GÜÇLENDİRME SONRASI Bölge nesne

Question

Aşağıdaki GÜÇLENDİRME API sahiptir:

@POST("/payments")  
Observable<Response> saveCreditCard(@Body CreditCard creditCard) 

CreditCard bir RealmObject olup.

benim API yöntemini kullanmaya çalıştığınızda: aşağıdaki hatayı alıyorum

CreditCard card = realm.createObject(CreditCard.class); 
card.setWhateverField(...); 
... 
mApi.saveCreditCard(card) 
    .subscribeOn(Schedulers.io()) 
    .observeOn(AndroidSchedulers.mainThread()) 
    .subscribe(...); 

:

O RETROFIT io() zamanlayıcı üzerinde JSON için seri yaptığını varsayıyorum, dolayısıyla hata.

Realm'in iş parçacığı sorununu nasıl aşabileceğime dair herhangi bir önerim var mı?

kod 2 ilave hatları gerektiren bir çözüm bulundu ve:

Answer 1

UPDATE

Realm aşağıdaki realm.copyFromRealm(yourObject, depthLevel)

CreditCard creditCard = realm.createObject(CreditCard.class); 
card.setWhateverField(...); 
... 

final int relationshipsDepthLevel = 0; 
creditCard = realm.copyFromRealm(creditCard, relationshipsDepthLevel); 
mApi.saveCreditCard(temporaryCard) 
    .subscribeOn(Schedulers.io()) 
    .observeOn(AndroidSchedulers.mainThread()) 
    .subscribe(...); 

DEPRECATED CEVAP kullanarak nesneleri ayırmak için ek destek Ekstra bir serileştirme adımı.

@Inject 
ObjectMapper mObjectMapper; // I use Dagger2 for DI 

.... 

CreditCard creditCard = realm.createObject(CreditCard.class); 
card.setWhateverField(...); 
... 
// I use Jackson's ObjectMapper to "copy" the original creditCard 
// to a new temporary instance that has not been tied to a Realm. 
String json = mObjectMapper.writeValueAsString(creditCard); 
PaymentCreditCardDataView temporaryCard = mObjectMapper 
        .reader(PaymentCreditCardDataView.class) 
        .readValue(json); 
mApi.saveCreditCard(temporaryCard) 
    .subscribeOn(Schedulers.io()) 
    .observeOn(AndroidSchedulers.mainThread()) 
    .subscribe(...); 

olumsuz

Ben UI iş parçacığı üzerinde, extra nesne ve ekstra seri + deserialisation adımı olması. Makul boyutlarda nesnelerim varsa tamam olmalı.
