Can I add KinveyReferences and other custom Arrays to the User entity?
1 Comment
The User class extends GenericJson, which is used throughout the library as our JSON representation. This provides both put(String key, Object value) as well as get(String key) for setting and retrieving arbitrary JSON data.
To add new data to your User object, try something like this:
//add "myJsonKey":"myJsonValue" to the current User object
kinveyClient.user().put("myJsonKey", "myJsonValue");
//put a new KinveyReference to another user
kinveyClient.user().put("friend", new KinveyReference(User.USERCOLLECTIONNAME, myFriendID));
//and finally, call update to send your changes to your backend
kinveyClient.user().update(new KinveyUserCallback() {
@Override
public void onSuccess(User result) {
//update successfull!
}
@Override
public void onFailure(Throwable error) {
//uh oh, something went wrong
}
});
If you want to resolve KinveyReferences on the current user, you can use one of the variations of the retrieve method. This retrieve methods to resolve KinveyReferences all take a String[]. which contains all JSON keys to resolve. In this case, it is "friend" as it was set above.
kinveyClient.user().retrieve(new String[]{"friend"}, new KinveyUserCallback() {
@Override
public void onSuccess(User result) {
//got the user with friend resolved
}
@Override
public void onFailure(Throwable error) {
//uh oh, something went wrong
}
});
KinveyReferences can also be set in Arrays, so you can call store multiple references in one field.
