Changing nav-bar links according to whether a user has created a profile or not (RoR)

im making a rails app and have created a simple navbar that works fine. I have set up devise and created a profile model which i would like users to create after they sign up, and (I believe) I have correctly made the necessary associations. As a new user signs in for the first time, I would like a "Create profile" link to show in the nav-bar using the new_profile_path, but once that specific user has created his/her profile, i would like the "create Profile" to change to "View Profile" and remain that way permanently, which should redirect to the profile_path.

The code I currently have in my nav-bar is the following:

<ul>
         <li><%= link_to root_path do %>
                <i class="fa fa-home"></i>Main
            <% end %>
        </li>
        <% if current_user.profile %>
         <li><%= link_to profile_path(current_user.profile) do %>
                    <i class="fa fa-user"></i>Employee Profile<i class="fa fa-sort-desc"></i>
                <% end %>
            <% end %>
            <% else %>
            <li><%= link_to "New Profile", new_profile_path %></li>
                <ul>
                    <li><%= link_to "Tasks / Activities", tasks_path %></li>
                    <li><%= link_to "Vacations", vacations_path %></li>
                </ul>
         </li>
         <li><%= link_to projects_path do %>
                <i class="fa fa-building-o"></i>Projects<i class="fa fa-sort-desc"></i>
                <% end %>
            <ul>

However even after creating the new profile the link "Create Profile" still remains. How can I fix this?
