title: devise roles: different roles, in some cases same rights
body: <p>I have two roles in devise. The first is the admin and the second the normal user-role.
  Now I´d like to give these two groups in some cases same rights with before filters.</p>
  
  <p>How does this work?</p>
  
  <p>I have:</p>
  
  <pre><code>before_filter :authenticate_user!, :only =&gt; [:new, :create]
  before_filter :authenticate_admin!, :only =&gt; [:new, :create, :edit, :update, :destroy]
  </code></pre>
  
  <p>But now only a user can :new and :create...the admin not..
  What I have to do here?</p>
  
  <p>Thanks, 
  Mattherick</p>
