io.realm.exceptions.RealmException: ContactsModel ist nicht Teil des Schemas für dieses Realm

Question

Beim Versuch, auf die Realm-Datenbank zuzugreifen, die obige Ausnahme erhalten.

Hier ist mein Code:

public Observable<RealmResults<ContactsModel>> getAllContacts() { 
     RealmResults<ContactsModel> contactsModel = realm.where(ContactsModel.class).notEqualTo("id", PreferenceManager.getID(mContext)).equalTo("Exist", true).findAllSorted("Linked", Sort.DESCENDING, "username", Sort.ASCENDING).sort("Activate", Sort.DESCENDING); 
     return Observable.just(contactsModel); 
    } 

ich einige dieser Lösungen versucht hatte, aber half mir nicht.

Answer 1

Ich glaube, Sie Problem mit Ihnen Realm-Konfiguration haben, und versuchen, von Modell zu schaffen durch verlängernRealmObject statt implementieren

hinzufügen defaultConfiguration

==> SetDefaultConfiguration < ==

Realm.init(this); 

RealmConfiguration mRealmConfiguration = new RealmConfiguration.Builder() 
       .name("yourDBName.realm") 
       .schemaVersion(1) // skip if you are not managing 
       .deleteRealmIfMigrationNeeded() 
       .build(); 

Realm.getInstance(mRealmConfiguration); 
Realm.setDefaultConfiguration(mRealmConfiguration); // add this line in your configuration 

Dann bekommen Realm wie

Realm.getDefaultInstance(); 

Answer 2

Sie nicht hinzu @RealmClass Anmerkung. Wenn Sie implements RealmModel verwenden, müssen Sie auch @RealmClass hinzufügen.

@RealmClass 
public class ContactsModel implements RealmModel { 

Siehe the docs.
