Can I use the same instance to do multipe Save?

[Wuping_Xin]

Can I re-use the same entity to do the save multiple times, like below?

var MyEntity := TMyEntity.Create;

for I := 0 to 1000 do begin
MyEntity.Name := RandomName();
ObjectManager.Save(MyEntity);
end

No, because the manager needs to track the instance of each entity. If you do that, the same instance will be associated with multiple entities (with different ids).

You must either create a new instance before each Save, or use Replicate method which will automatically create a new instance and copy the properties from the original instance to the new one.
