title: Difference between render :action and render :template
body: <p>What is the difference between <code>render :action =&gt; "new"</code> and <code>render :template =&gt; "users/new"</code>? I have heard that rendering template, we can use for views from other controllers. Is that it or is there any difference in rendering layout also between the two? For render :template, is it neccessary to have an action defined or is the view page itself enough?</p>
