has_role? does not use preloaded data, but always makes a query

[vfonic]

I preload current user roles in my app like this (I use devise for auth):

class ApplicationController < ActionController::Base
  def current_user
    @current_user ||= super.tap do |user|
      ::ActiveRecord::Associations::Preloader.new.preload(user, :roles)
    end
  end
end

When I call user.has_role?(:staff, company), the SQL query is executed, disregarding the fact that I have all the roles loaded in memory for the user. How can I avoid that? Is there a reason we couldn't make this the default?

Here's the debugging output:

>  user.has_cached_role?(:staff, record)
true
>  user.roles.loaded?
true
>  user.has_role?(:staff, record)
  Role Exists? (0.6ms)  SELECT 1 AS one FROM "roles" INNER JOIN "users_roles" ON "roles"."id" = "users_roles"."role_id" WHERE "users_roles"."user_id" = $1 AND "roles"."name" = $2 AND "roles"."resource_type" = $3 AND "roles"."resource_id" = $4 LIMIT $5  [["user_id", 3], ["name", "staff"], ["resource_type", "Entity"], ["resource_id", 21], ["LIMIT", 1]]
  ↳ (pry):3:in `show?'
true
>  user.has_role?(:staff, record)
  CACHE Role Exists? (0.0ms)  SELECT 1 AS one FROM "roles" INNER JOIN "users_roles" ON "roles"."id" = "users_roles"."role_id" WHERE "users_roles"."user_id" = $1 AND "roles"."name" = $2 AND "roles"."resource_type" = $3 AND "roles"."resource_id" = $4 LIMIT $5  [["user_id", 3], ["name", "staff"], ["resource_type", "Entity"], ["resource_id", 21], ["LIMIT", 1]]

Thanks!
