So here is the thing:
I have an Object Product which extends RealmObject. Inside the Product object, there is an attribute: RealmList. Bundle also extends RealmObject.
Inside the Bundle Object, there is an attribute: RealmList. ProductBundle extends RealmObject.
Now all those lists are not empty nor null by the time they should be inserted.
After insertion, if I query Realm for a list of Products, I will receive a list that has a list of RealmList. However, inside each of the Bundle items, the RealmList< ProductBundle> productBundles is always empty.
class Product extends RealmObject{
RealmList<Bundle> bundles= new RealmList<Bundle>();
boolean isLocallyAddedToCart;
}
class Bundle extends RealmObject{
RealmList<ProductBundle> productsBundles = new RealmList<ProductBundle>();
}
class ProductBundle extends RealmObject{
String title;
}
Any thoughts on that??
Query:
RealmResults<Product> cartItem = realm.where(Product.class).equalTo("isLocallyAddedToCart", true).findAll();
Inserting:
public void insertAddToCart(@NonNull ArrayList<Product> items) {
try {
Realm realm = getRealmInstance();
realm.beginTransaction();
realm.insertOrUpdate(items);
realm.commitTransaction();
realm.close();
} catch (Exception ex) {
ex.getStackTrace();
}
}
Handling the objects:
RealmList<BundleProductOption> bundleProductOptions = new RealmList<>();
private SparseArray<List<ProductBundle>> optionsFinalSelection = new SparseArray<>();
BundleProductOption bundleProduct = new BundleProductOption();
bundleProduct.setDefaultTitle(bundleProductOption.getDefaultTitle());
bundleProduct.setOptionId(bundleProductOption.getOptionId());
bundleProduct.setParentId(bundleProductOption.getParentId());
bundleProduct.setRequired(bundleProductOption.getRequired());
bundleProduct.setType(bundleProductOption.getType());
RealmList<ProductBundle> productBundles = new RealmList<>();
productBundles.addAll(optionsFinalSelection.get(i));
bundleProduct.setProductsBundle(productBundles);
product.setSelectedOptions(bundleProductOptions);
you must manage your insertion with ID as a primary key in each model. when u insert or update u must use a primary key for saving all states of your data, and then u can do not use them, but realm need them for arrange insert or update method.
keep me updated with your issue .
