Postgres Ltree operators

[bencrouse]

I'm using a Postgres Ltree field and want to use one of its operators (e.g. <@) in a model query, but retain the rest of the QuerySet filtering, sorting, etc in the code I'm writing.

It seems like operators are hardcoded? I'm struggling to find out how to include some raw SQL in a QuerySet as well, since TypeError: expected Q objects as args.

Is there any way to get a Postgres Ltree operator into a QuerySet as part of the filter? Thanks!
