Question

I am passing a path as a parameter, so params[:path] would be name_path(:username => @user.name (I want to pass it as a path and not a url, so putting name_url in the params isn’t what I want).

Since you can only use redirect_to with a url, I need to change the path to a url before I can use redirect_to. How would I do this?

I found this method here

def path_to_url(path)
  "http://#{request.host_with_port_without_standard_port_handling}/#{path.sub(%r[^/],'')}"
end

But, this was written in 2008, and I want to know if there is a better way in Rails 3?

Answer 1

Updated copy from original path to url post btw: also works on Rails 2

# abs or /abs -> http://myx.com/abs
# http://grosser.it/2008/11/24/rails-transform-path-to-url
def path_to_url(path)
  "#{request.protocol}#{request.host_with_port.sub(/:80$/,"")}/#{path.sub(/^\//,"")}"
end
