It is not a matter of how you test for nil, it is a matter of how you
access the profile. You suggest using
Profile.find_by_user_id(current_user.id ) but you can just do
current_user.profile. It is the same thing but much easier to
understand. You can test for nil any way you like.

Thanks colin, happy holidays again ha ha Ok so then i'm using `if current_user.profile?` but the snippet is causing the error application.html.erb:59: syntax error, unexpected keyword_ensure, expecting end-of-input, even though application.html.erb is only 57 lines
<% user_signed_in? %>
<% if current_user.profile? %>
<%= "profile found" %>
<% else %>
<%= "profile not found" %>
<% end %>
<div class="dropdown">
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown"><%= current_user.email %></button>
<ul class="dropdown-menu"><span class="caret"></span>
<li><%= link_to('Profile', user_profile_path ) %></li>
<li><a href="#">Account</a></li>
<li><a href="#">Messages</a></li>
<li><%= link_to('Sign out', destroy_user_session_path, method: :delete) %></li>
</ul>
</div>
<% else %>
<div align=right>
<%= link_to('User sign in', new_user_session_path) %>
</div>
<% end %>
