    <p>I have an application where in the layout I have a user_name div which will display different things based on whether or not they are logged in, are an admin, etc. Right now my code is the following:</p> <pre><code> &lt;% if current_user.role == "admin" %&gt; &lt;p id="admintxt"&gt;You are an admin!&lt;/p&gt; &lt;%= link_to "Edit Profile", edit_user_path(:current) %&gt; &lt;%= link_to "Logout", logout_path %&gt; &lt;% elsif current_user %&gt; &lt;%= link_to "Edit Profile", edit_user_path(:current) %&gt; &lt;%= link_to "Logout", logout_path %&gt; &lt;% else %&gt; &lt;%= link_to "Register", new_user_path %&gt; &lt;%= link_to "Login", login_path %&gt; &lt;% end %&gt; </code></pre> <p>I have a current_user helper already and everything was working fine when the code was just:</p> <pre><code>&lt;% if current_user %&gt; &lt;%= link_to "Edit Profile", edit_user_path(:current) %&gt; &lt;%= link_to "Logout", logout_path %&gt; &lt;% else %&gt; &lt;%= link_to "Register", new_user_path %&gt; &lt;%= link_to "Login", login_path %&gt; &lt;% end %&gt; </code></pre> <p>Now when I make it an elsif statement, when I am logged in as an admin it works and I get the text displayed with the correct links. When I am not an admin user/logged out, I get a undefined method `role' for nil:NilClass error... Also my current_user stuff is declared in my application controller as follows:</p> <pre><code>helper_method :current_user private def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session &amp;&amp; current_user_session.record end </code></pre> <p>Any ideas what I can do to display the result I want? "If they are a user with the role attribute equal to admin they get some text and the logged in links, if they are just a user they get the logged in links, and if they are not logged in they get the register and login links.</p> <p>Thanks!</p>

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.
