Hi there!

I've got code duplication using strong_parameters:

class PeopleController < ApplicationController
  # ...

  protected
    def person_params
      params.permit(:name, pets: [ :name, :age ])
    end
end

###

class PetsController < ApplicationController
  # ...

  protected
    def pets_params
      params.permit(:name, :age)
    end
end

So if I need change permitted params for pets I should change it in two 
files.
Am I doing wrong? Or how can I avoid code repetition?

Thanks in advance!
