Filter query by current user

Schema:

DB Schema

How do I filter a query based on the current user in a joined table?

The closest I've come is with using:

query = supabase.from('shows').select('*, user__shows!left (*)')

if ($user) {
    query = query.not('user__shows.watched', 'is', true)
}

I'm pretty sure it's duplicating entries though which is why it doesn't work on the second query.

I also tried creating a view:

create view browse as
SELECT shows.id, title, year, blurb, imdb_rating, imdb_count, seasons, trailer, status, runtime, country, language, episodes, genres, network, user_id, watched, hidden
FROM user_shows
RIGHT JOIN shows
ON user_shows.show = shows.id
GROUP BY shows.id, watched, hidden, user_id

That didn't filter by current user though.

So, any help would be greatly appreciated.

Figured it out and posting the answer for any future souls that are also stumped.

The view works

-- create view browse as
-- SELECT shows.id, title, year, blurb, imdb_rating, imdb_count, seasons, trailer, status, runtime, country, language, episodes, genres, network, watched, hidden
-- FROM shows
-- LEFT JOIN user__shows
-- ON user__shows.show = shows.id
-- GROUP BY shows.id, watched, hidden

the caveat being that row level security works at the level of the view's owner so you have to modify it with

-- ALTER VIEW browse OWNER TO authenticated;

and then I just wrapped it up in an if statement

if ($user) {
    query = supabase.from('browse').select('*')
} else {
    query = supabase.from('shows').select('*')
}
