Is it possible to update only one field to Realm?












0














Android Studio 3.2, Java 1.7, Realm 4.1.0



Here my pojo:



public class ImageFormats extends RealmObject {
private ImageSource reference;
private ImageSource average;
}


public class ImageSource extends RealmObject {
private String url;
private int width;
private int height;
}


Here how I update reference



public void cascadeUpdate(Realm realm, ImageFormats that) {
if (!EqualsUtil.areEqual(this.average, that.average)) {
setAverage(that.average == null ? null : realm.copyToRealm(that.average));
}
}


Nice it work fine.



But I wan't to update WHOLE object ImageSource because may change only one property, e.g. url



And I try to update to Realm only field that was changed.
So I try this:



public void cascadeUpdate(Realm realm, ImageSource that) {
if (!EqualsUtil.areEqual(this.url, that.url)) {
setUrl(that.url == null ? null : realm.copyToRealm(that.url)); // error here
}
}


But I get compile error:



error: no suitable method found for copyToRealm(String)


So, how I can update to Realm only changed field?

  • Get the object from the Realm and use the object's setter instead of copyToRealm

  • So this code is correct? - public void cascadeUpdate(Realm realm, ImageSource that) { if (!EqualsUtil.areEqual(this.url, that.url)) { setUrl(that.url); } }

  • Actually now that you mention it, the latest version should support ImportFlag on copyToRealmOrUpdate which should be able to do what you need.

  • (The latest version is 5.8.0, so I guess the right way for you IS to fetch the object and set it if it's not equal, so yeah)
