Posthook grant schema usage

[nstein-gpjoule]

Hi,

I'm new to dbt, and just saw that DBT is not applying grants to the schema the models resides in.

I now had the idea to put a post_hook config in every model.

{{ config(
    materialized='view',
    grants = {
    '+select': ['ROLE_A', 'ROLE_B'] }
    post_hook = '{% for role in something %}GRANT USAGE ON {{ target.schema }} TO {{ role }}{% endfor %}'
) }}

Would this be possible? Is there a way to collect all roles for the current target? Since grants is a dictionary how can I concatenate all roles (and make them unique)?
