How to automatically set all links to nofollow in Rails

Question

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?

Answer 1

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

In case you don't want to overwrite any rel values already on your link, try using merge_nicely! instead: gist.github.com/joshuapinter/78a5545d713ab9d55883 – Rooney

Answer 2

You could create an alias to the old link_to then override it so it calls the old alias with the extra parameter. That way, you don't have to change all the existing link_to in your code.
