    <p>I am attempting to display the current users name once they are logged in. </p> <p>Therefore at the top of the page it would say "Logged in as Patrick". However I have a polymorphic association set up whereby every user that signs up is either a player or a coach.</p> <p>The polymorphic association is under the label or :tennis_player as both coach and player play tennis.</p> <p>The code for the view is below.</p> <pre><code> &lt;div class="container"&gt; &lt;header&gt; &lt;div class="logo"&gt; &lt;%= link_to(image_tag 'tennis_ball.png', :width =&gt; 100, :height =&gt; 100) %&gt; &lt;/div&gt; &lt;div class="slogan"&gt; &lt;h3&gt;Setfortennis&lt;/h3&gt; &lt;/div&gt; &lt;div id="user_nav"&gt; &lt;% if current_user? %&gt; Logged in as &lt;%= @current_user %&gt; &lt;%= link_to "log out", log_out_path %&gt; &lt;% else %&gt; &lt;%= link_to "Sign Up", sign_up_path %&gt; or &lt;%= link_to "Log in", log_in_path %&gt; &lt;% end %&gt; &lt;/div&gt; &lt;/header&gt; &lt;/div&gt; </code></pre> <p>Here is my application controller</p> <pre><code> helper_method :current_user? before_filter :get_user def current_user? !!current_user end def current_user @current_user ||= session[:user_id] &amp;&amp; User.find_by_id(session[:user_id]) end def check_logged_in redirect_to( new_session_path, :notice =&gt; "You must be logged in to do that!") unless current_user? end def get_user @user = User.new end end </code></pre> <p>And here are my models.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
