Feature request: has_scope for other models in a controller

[mzemel]

If I have a model

class Bar
  belongs_to Foo
  scope :active, ->{ where(status: "active") }
end

and another resource's controller (FooController), it would be really cool if I could somehow add a flag to has_scope to tell the controller that the scope belongs on an ActiveRecord Relation of Bar objects:

class FooController < ApplicationController
  has_scope :active # add something here

  def show
    apply_scopes(Foo.find(params[:id]).bar).all
  end
end

If this makes sense, maybe it's something I could try putting a PR together for. It doesn't look possible from the source code (couldn't determine naming deductions, but I'm assuming you get the model from the naming of the controller) but if it is possible and you could tell me how to do that, I'd love to use this gem.

Never mind; the target is whatever's passed to #apply_scopes, not inferred from the controller name; I was using it wrong.
