Accessing a reason from a nested allowed_to?

[brendon]

I have something like this:

class ComponentInstancePolicy < ApplicationPolicy
  pre_check :deny_deleted_component_instances

  def view?
    record.has_permission_to(:view, user)
  end

  private

  def deny_deleted_component_instances
    deny!(:deleted) if record.deleted?
  end
end

class InstancePolicy < ApplicationPolicy
  def view?
    allowed_to?(:view?, record.component_instance)
  end
end

When I call authorize! my_instance, to: :view?, with: InstancePolicy on a deleted component_instance and inspect the exception: exception.result.reasons I get:

#<ActionPolicy::Policy::FailureReasons:0x00007f89d3bc2c08 @reasons={ComponentInstancePolicy=>[:view?]}>

What I really want is :deleted for the reason so that I can provide a nice error message.

Is there a way to do this?

I have a failing test here that demonstrates the problem: brendon@1ed2e20

Perhaps I'm misunderstanding the deny!(:reason) approach but from memory it used to be properly exported as the failure reason (fast fail).
