Hi
No, I'm sorry but we don't have another way other the supplied by the korzh Easy Query Library
Data Model Editor.
Our main role is to allow you to integrate modern plugins used world web wide, by other web dev platforms, into Delphi, we cannot become specialist on every plugin we encapsulate.
why you say isn't easy? It's not dynamic is that it? cannot controlled by code, i presume.
If you can put some of time with it, maybe we can make a model dynamically by other means. It's not a difficult task, but requires the model json structure to be studied.
