"All children where parents.id not in ...."?

[solars]

Hi there,

I need to select all Items that do have having their parent (or better root) NOT in a list of objects.
What's the best way to do this? I could do it with LIKE on the ancestry, combined by ORs but that's not really nice..

Thanks a lot

I don't know how to do this.
I'm guessing a not like may be your best bet.

@kbrock hm I think it could also be done with: #280 and negate it? But I'm not sure how this method is called (Rails 4.2)
