Hello,
I’m migrating to Backendless 4 at the moment but I’m struggling with saving and relations.
I have a table Exercise and a table Favorites. In my table favorites I’m trying to save a relation to my exercise using the follwing code:
private void addToFavorites() {
isConnected = networkUtil.checkInternetConnectivity();
if (isConnected) {
showSnackbar(getResources().getString(R.string.info_adding_exercise_to_favorites));
floatingActionButton.setClickable(false);
final Favorites favorites = new Favorites();
final DataQueryBuilder queryBuilder = DataQueryBuilder.create();
String whereClause = "objectId='" + exerciseObjectId + "'";
queryBuilder.setWhereClause(whereClause);
Backendless.Data.of(Exercise.class).find(queryBuilder, new AsyncCallback<List<Exercise>>() {
@Override
public void handleResponse(List<Exercise> response) {
for (Exercise exercise : response) {
favorites.setExercise(exercise);
}
Backendless.Data.save(favorites, new AsyncCallback<Favorites>() {
@Override
public void handleResponse(Favorites response) {
showSnackbar(getResources().getString(R.string.info_exercise_saved_successfully));
floatingActionButton.setImageDrawable(ResourcesCompat.getDrawable(getResources(), R.mipmap.ic_fab_star, null));
favorited = true;
floatingActionButton.setClickable(true);
}
@Override
public void handleFault(BackendlessFault fault) {
showSnackbar(fault.getMessage());
floatingActionButton.setClickable(true);
}
});
}
@Override
public void handleFault(BackendlessFault fault) {
showSnackbar(fault.getMessage());
}
});
} else {
Toast.makeText(getApplicationContext(), getString(R.string.info_not_connected_to_the_internet), Toast.LENGTH_LONG).show();
}
}
A new line is added in my Data Browser but the field related to the exercise remains empty. This used to work in Backendless 3.x but can’t find a solution for backendless 4.
I tried using the documentation but no luck (https://backendless.com/docs/android/doc.html#data_relations_api_set_add_android)
Somebody willing to try and help me?
Kind regards
