      Comparing equality between `ActionController::Parameters` and a
      `Hash` is deprecated and will be removed in Rails 5.1. Please only do
      comparisons between instances of `ActionController::Parameters`. If
      you need to compare to a hash, first convert it using
      `ActionController::Parameters#new`.
