Access current collection and field in input-component.vue for custom filter validation logic

I’m working on customizing the system filter logic in the Directus system filter component. Specifically, I’m looking at this section of the code:

The issue I’m facing is that for fields like "user_created", the current logic expects a UUID by default (since it is a relational field). So when I try to apply a filter like:

{
  "user_created": {
    "_contains": "smith"
  }
}

it doesn’t pass validation.

However, based on some configuration, I want to override this behavior. Specifically, I want to intercept and transform the filter into a nested form like this:

{
  "user_created": {
    "first_name": {
      "_contains": "smith"
    }
  }
}

To do this, I need access to both:

  • The current collection being filtered
  • The current field (e.g., "user_created" in this case)

How can I access the current collection name and field key within input-component.vue or higher up in system-filter.vue so that I can apply custom validation logic based on field types or collection-specific rules?

Any guidance on the best way to inject or retrieve this contextual information would be greatly appreciated.
