Using link_to with conditions

I'm using the following code to display the name of the contact and link to their message. 

<%= link_to message.contact.try(:name), message_path(message) %>

When a contact is deleted from the list, I would like to show a placeholder like "Contact deleted" and link to the message instead of just showing the URL. I tried link_to_if, but it didn't offer the expected output. Is there an effective solution for this?

You can use link_to_if if the name of the link is the same. You can also use it with a workaround.

<%= link_to_if message.contact, message.contact ? message.contact.name : "Contact deleted", message_path(message) %>

However, I think the cleanest approach is an if.

<% if message.contact %>
  <%= link_to message.contact.name, message_path(message) %>
<% else %>
  Contact deleted
<% end %>
