<p>Django's class based views are a welcome departure from the old-style views.</p>

<h1 id="views">Views</h1>
<p>REST framework provides a simple <code>APIView</code> class, built on Django's <code>django.generics.views.View</code>. The <code>APIView</code> class ensures five main things:</p>
<ol>
<li>Any requests inside the view will become <code>Request</code> instances.</li>
<li><code>Request</code> instances will have their <code>renderers</code> and <code>authentication</code> attributes automatically set. </li>
<li><code>Response</code> instances will have their <code>parsers</code> and <code>serializer</code> attributes automatically set.</li>
<li><code>APIException</code> exceptions will be caught and return appropriate responses.</li>
<li>Any permissions provided will be checked prior to passing the request to a handler method.</li>
</ol>
<p>Additionally there are a some minor extras, such as providing a default <code>options</code> handler, setting some common headers on the response prior to return, and providing the useful <code>initial()</code> and <code>final()</code> hooks.</p>

<h2 id="method-handlers">Method handlers</h2>
<p>Describe that APIView handles regular .get(), .post(), .put(), .delete() etc...</p>
