How to use pundit policy check within tabulatr2 data definition?

Question

I'm using tabulatr2 to handle table alike data. However I can't wrap my head around how to include pundit's policy checks in tabulatr2's data definition.

So I have something akin to

class MystuffTabulatrData < Tabulatr::Data
  column :blah
  buttons do |b,r|
    if policy(r).destroy? # XXX: NoMethodError - undefined method `policy' for #<Data::Proxy:0x83f84bb0>
      ...
    end
  end
end

One usually uses something like <%= table_for Mystuff %> in a view.

Answer 1

Since we work with Data::Proxy there, the source suggests that @controller should be available. So @controller.policy(r) works just fine.
