    <p>I have created an app which uses devise and cancan for authentication and authorization . Using cancan I have defined two roles admin and operator. The admin can manage all and the operator can edit all but not destroy and the third is a normal user who can create and manage. But the code goes only to the default else block. This is my ability class and index.html </p> <pre><code>class Ability include CanCan::Ability def initialize(user) user ||= User.new # guest user if user.role? :admin can :manage, :all elsif user.role? :operator can :read, :all else can :read, :all end end end </code></pre> <p>index.html</p> <pre><code> &lt;h1&gt;Listing todos&lt;/h1&gt; &lt;table&gt; &lt;tr&gt; &lt;th&gt;Name&lt;/th&gt; &lt;th&gt;Description&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;/tr&gt; &lt;% @todos.each do |todo| %&gt; &lt;tr&gt; &lt;td&gt;&lt;%= todo.name %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= todo.description %&gt;&lt;/td&gt; &lt;% if can? :show, @todo %&gt; &lt;td&gt;&lt;%= link_to 'Show', todo %&gt;&lt;/td&gt; &lt;% end %&gt; &lt;% if can? :update, @todo %&gt; &lt;td&gt;&lt;%= link_to 'Edit', edit_todo_path(todo) %&gt;&lt;/td&gt; &lt;% end %&gt; &lt;% if can? :destroy, @todo %&gt; &lt;td&gt;&lt;%= link_to 'Destroy', todo, :confirm =&gt; 'Are you sure?', :method =&gt; :delete %&gt;&lt;/td&gt; &lt;% end %&gt; &lt;/tr&gt; &lt;% end %&gt; &lt;/table&gt; &lt;br /&gt; &lt;% if can? :destroy, @todo %&gt; &lt;%= link_to 'New Todo', new_todo_path %&gt; &lt;% end %&gt; </code></pre>

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.
