how to hide string in ruby on rails

Question

In the view have a string, that shows from a database string with the website address. How to make so that would absence of this website address in the database, the string will not be displaying the view?

website:
<%= link_to @restaurant.site, url_with_protocol(@restaurant.site) >

in the absence website address remains the first string, and I wish that it only appears when there address

PS

That this could be done, as in writing this code:

<% if session[:user_id] %> <% end >

which displays information only if the user is registered.

Just do it the same way.

<% if @restaurant.site %>
  <%= link_to @restaurant.site, url_with_protocol(@restaurant.site) %>
<% end %>
