推荐答案

所有 url 和 path 辅助方法都接受可选参数.
您正在寻找的是 anchor 参数:

All url and path helper methods accept optional arguments.
What you're looking for is the anchor argument:

question_path(123, :anchor => "answer-345")

它记录在 URLHelper#link_to 示例.

使用此参数，您应该能够通过以下方式创建 answer_path 帮助程序:

Using this argument, you should be able to create an answer_path helper via:

module ApplicationHelper

  def answer_path(answer)
    question_path(answer.question, :anchor => "answer-#{answer.id}")
  end

end
