Android Realm Beziehung return null

Question

Ich habe Modellklasse als RealmObject die ProductsDetailInformation genannt, in diesem Modell i-Einfeld haben als

private RealmList<ProductSlideShowImages> slideShowImages; 

, die ich dieses Produkt Bilder von ProductSlideShowImages Modell erhalten wollen, aber mein dieser Test Rückkehr [0], zum Beispiel:

ProductsDetailInformation = [ 
    {id: 57f72549-53e1-4177-9e52-80b8421559b7}, 
    {marketId: bc76b7a5-3166-11e6-b8fe-ec9a74f8851a}, 
    {productId: bc76b7a5-3166-11e6-b8fe-ec9a74f8851a-123456}, 
    {weight: 10}, 
    {cost: 1000}, 
    {color: blue}, 
    {madeIn: china}, 
    {gender:}, 
    {sex:}, 
    {quality: low}, 
    {size: 42}, 
    {sizeModel: xxl}, 
    {count: 10}, 
    {rating: 2}, 
    {description: my description}, 
    {created_at: 2016 - 07 - 17}, 
    {updated_at: 2016 - 07 - 14}, 
    {slideShowImages: RealmList <ProductSlideShowImages> [0]} 
] 

in beide marketId und productId haben die gleichen Daten.

ProductsDetailInformation Klasse:

public class ProductsDetailInformation extends RealmObject{ 

    @PrimaryKey 
    private String id; 
    private String marketId; 
    private String productId; 
    private String weight; 
    private String cost; 
    private String color; 
    private String madeIn; 
    private String gender; 
    private String sex; 
    private String quality; 
    private String size; 
    private String sizeModel; 
    private String count; 
    private String rating; 
    private String description; 
    private String created_at; 
    private String updated_at; 

    /** 
    * RelationShip columns with ProductSlideShowImages table 
    */ 
    private RealmList<ProductSlideShowImages> slideShowImages; 

    /*SETTER AND GETTER*/ 
} 

ProductSlideShowImages Klasse:

public class ProductSlideShowImages extends RealmObject{ 
    @PrimaryKey 
    private String id; 
    private String marketId; 
    private String productId; 
    private String imageFileName; 
    private String created_at; 
    private String updated_at; 

    /*SETTER AND GETTER*/ 
} 

mit Abfrage Ergebnis:

List<ProductsDetailInformation> productsDetails = 
realm.where(ProductsDetailInformation.class).equalTo("marketId",marketUUid).findAll(); 

ProductSlideShowImages Modell und ProductsDetailInformation doesnt zusammen füllen sie auf Differenz Platz füllen sind und tim e

EDIT:

dies unter trasaction speichern i Informationen zu ProductSlideShowImages Modell

realm.executeTransaction(new Realm.Transaction() { 
    @Override 
    public void execute(Realm realm) { 
     ProductSlideShowImages slideShowImages = new ProductSlideShowImages(); 
     try { 
      //@formatter:off 
       slideShowImages.setId   (UUID.randomUUID().toString()    ); 
       slideShowImages.setMarketId  (jsonObject.getString ("marketId"  )); 
       slideShowImages.setProductId  (jsonObject.getString ("productId"  )); 
       slideShowImages.setImageFileName (jsonObject.getString ("imageFileName" )); 
       slideShowImages.setCreated_at (jsonObject.getString ("created_at"  )); 
       slideShowImages.setUpdated_at (jsonObject.getString ("updated_at"  )); 
      //@formatter:on 
      realm.copyToRealm(slideShowImages); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
    } 
}); 

und mit unter Transaktion in anderen Verfahren i Daten ProductsDetailInformation Modell speichern:

realm.executeTransaction(new Realm.Transaction() { 
    @Override 
    public void execute(Realm realm) { 
     ProductsDetailInformation products = new ProductsDetailInformation(); 
     try { 
      //@formatter:off 
       products.setId   (UUID.randomUUID().toString()   ); 
       products.setMarketId  (jsonObject.getString ("marketId" )); 
       products.setProductId  (jsonObject.getString ("productId" )); 
       products.setWeight  (jsonObject.getString ("weight"  )); 
       products.setCost   (jsonObject.getString ("cost"  )); 
       products.setColor   (jsonObject.getString ("color"  )); 
       products.setMadeIn  (jsonObject.getString ("madeIn"  )); 
       products.setGender  (jsonObject.getString ("gender"  )); 
       products.setSex   (jsonObject.getString ("sex"   )); 
       products.setQuality  (jsonObject.getString ("quality"  )); 
       products.setSize   (jsonObject.getString ("size"  )); 
       products.setSizeModel  (jsonObject.getString ("sizeModel" )); 
       products.setCount   (jsonObject.getString ("count"  )); 
       products.setRating  (jsonObject.getString ("rating"  )); 
       products.setDescription (jsonObject.getString ("description" )); 
       products.setCreated_at (jsonObject.getString ("created_at" )); 
       products.setUpdated_at (jsonObject.getString ("updated_at" )); 
      //@formatter:on 
      realm.copyToRealm(products); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
      Log.e("Error ", " parse json objects"); 
     } 
    } 
});

Sie müssen Ihre Beziehungen manuell festlegen.

ProductsDetailInformation products = new ProductsDetailInformation(); 
    products.setSlideShowImages(new RealmList<ProductSlideShowImages>()); 
    try { 
     ... 
     RealmResults<ProductSlideShowImages> slideShows = realm 
      .where(ProductSlideShowImages.class) 
      .equalTo("marketId", products.getMarketId()) 
      .findAll(); 
     for(ProductSlideShowImages slideShow : slideShows) { //only 0.89.0+ 
      products.getSlideShowImages().add(slideShow); 
     } 
     realm.copyToRealm(products);
