-- Migration: Fix weekly_goals.user_id by updating it from projects.user_id
-- This migration fixes the issue where weekly_goals.user_id was incorrectly set to NULL or wrong user_id
-- It updates all weekly_goals records to have the correct user_id from their associated project

UPDATE weekly_goals wg
SET user_id = p.user_id
FROM projects p
WHERE wg.project_id = p.id
  AND (wg.user_id IS NULL OR wg.user_id != p.user_id);
