Rails: Be careful with params.merge()

I’ve seen a lot of people doing it and I used to do it too, use params.merge(…) in link_to or redirect_to calls. You do this because you want to change one ore more parameters (like the locale, current page or search query) but leave the rest as it is. But heads up, there is an issue with this solution!

You can use basic HTML markup (e.g. <a>) or Markdown.
