I want to create object Advertisement with relation : Comments, Photos, GeoPoints…
in 3.0 version, I saved Advertisement by one request,
Backendless.Data.of(Advertisement.class).save(advertisement)
How to save object with all this relations by one request?
If the child objects are not in the database, then every object must be saved individually first and then a relation can be established between the parent and the children.
Why you removed this option, when you save parent object, all child objects saved automatically
Because it improves server stability and scalability.
