Question

In my Ruby on Rails 3.1 app I have a link like this:

<%= link_to 'Home', root_url %>

On My dev. machine it renders a link with “localhost:3000”. On production it renders a link with an IP Address like this “83.112.12.27:8080”. I would like to force rails to render the domain address instead of the IP Address. How can I set root_url?

Answer 1

In your routes set:

 root :to => 'welcome#index'

and in your links set:

<%=link_to "Home", root_path %>

It will render

<a href="/">Home</a>

So in your localhost It’d take you to

http://localhost:3000/

and in your production server It’d take you to

http://yourdomian.com/

and the routes.rb will render the index action of the controller welcome by default.

PS. you also need to remove index.html from public directory in order to use this.
