Pundit policies with two input parameters

I'm pretty new with Rails and I have a problem with the following policies (using Pundit): I'd like to compare two objects: @record and @foo, as you can see here:

class BarPolicy < ApplicationPolicy
  def show?
    @record.foo_id == @foo
  end
end

I don't reach to find a good way to pass a second parameter to pundit methods (@foo).

I'd like to do something like:

class BarsController < ApplicationController
  def test
    authorize bar, @foo, :show? # Throws ArgumentError
    ...
  end
end

But the Pundit authorize method allows only two parameters. Is there a way to solve this issue?

Thanks!

I found the answer at here.

Here is my way:

Add a pundit_user function in ApplicationController:

class ApplicationController < ActionController::Base
include Pundit
def pundit_user
    CurrentContext.new(current_user, foo)
end

Create the CurrentContext class:

/lib/pundit/current_context.rb
class CurrentContext
  attr_reader :user, :foo

  def initialize(user, foo)
    @user = user
    @foo = foo
  end
end

Update the initialize Pundit method.

class ApplicationPolicy
  attr_reader :user, :record, :foo

  def initialize(context, record)
    @user = context.user
    @foo = context.foo
    @record = record
  end
end
