Rails: How to add external link to rails app

I have a string in which users input a URL, which is later displayed in index.html. How can I turn that into a working external link? Right now, the link displays as should (e.g. www.facebook.com/tester), but when I click on the link I get a no route matches "/www.facebook.com/tester" routing error. I tried user.facebook.link but that didn't work.

I tried adding href=" " also but with no luck.

<%= link_to nil, user.facebook %>
Solution

  • As mentioned by @Mischa, you can add:

    <%=link_to nil, "http://#{user.facebook}"%>

    to have the protocol added to link.

    If you need to give the link a label, say, Facebook, you can use it:

    <%=link_to 'Facebook', "http://#{user.facebook}"%>`

    That's all.

    I hope this helps
