如何让过滤器重定向到另一个动作？

class MyController< ApplicationController
  before_action :redirect_filter, only: [:index]

  def index
    # Your code here
  end

  def new_action
    # Your code here
  end

  private

  def redirect_filter
    if some_condition
      redirect_to new_action_path
    end
  end
end
