如何在Rails中自动将所有链接设置为nofollow

问题描述

我知道我可以通过 :rel =>nofollow" 到 link_to 但有没有办法在默认情况下设置它，这样我就不必在每个 link_to 标签中进行更改?

I know I can pass :rel => "nofollow" to link_to but is there a way to set that by default so I don't have to make changes in each link_to tag?

推荐答案

在您的应用程序助手中，您可以覆盖 link_to 方法并替换为您自己的方法.

In your application helper you can override the link_to method and replace with your own.

def link_to(name, options = {}, html_options = {})
  html_options.merge!(:rel => :nofollow)
  super(name, options, html_options)
end
