Rails reverse autolink

Question

I have the following code in my Rails app:

link_to('???',{:controller => 'profile', :action => 'show', :id => id})

I want to get rid of '???' and it to show the dynamically generated URL. How do I this? It's kind of like what the autolink gem does, but I want Rails to convert URL options into text, not vice versa.

If link will convert into text then how it will be clickable? — sjain, Mar 12 '13 at 12:01

Use url_for() to get the string.

url_for({:controller => 'profile', :action => 'show', :id => id)}

In the code:

url_hash = {:controller => 'profile', :action => 'show', :id => id}
link_to(url_for(url_hash), url_hash)

See this question to also get the host name:

url_hash = {:controller => 'profile', :action => 'show', :id => id}
link_to("#{request.host_with_port}#{url_for(url_hash)}", url_hash)

link_to(nil,{:controller => 'profile', :action => 'show', :id => id})

From the link_to documentation:

If nil is passed as the name the value of the link itself will become the name
