Create Model with command line

Thanks @kenjis , @InsiteFX
So looking at your pointers does it means that if set to true then whenever we pass request data on model for easy to insert/update it will only validate only matching field/rules name on request data?
Does it also works not only on model but on every time we use validation library? I was thinking if i can make that some global validation that have all rules saved on validation config or separate files.
Sorry for my bad english.
