ruby on rails - link_to the current page plus/merged with a param

Question

Answer 1

You can use url_for passing the params.

url_for(params.merge(:c => "e"))

If you use an helper like link_to that internally uses url_for you can skip the url_for and pass the has directly.

link_to "Page", params.merge(:c => "e")
