-- Migration 008: Relax tickets resource foreign key constraints
|
||
|
|
-- Allows tickets to sync even if assigned resources don't exist in our database
|
||
|
|
-- This is necessary because:
|
||
|
|
-- 1. Some tickets may reference deleted/inactive resources
|
||
|
|
-- 2. Resource sync may be incomplete
|
||
|
|
-- 3. Autotask may have data inconsistencies
|
||
|
|
|
||
|
|
-- Drop the strict foreign key constraint on assigned_resource_id
|
||
|
|
