Get serializer field value in api-view
<p>Is it possible to get a field value from a serialized object in Django Rest Framework? Something like this:</p>

<pre><code>serializer = PostSerializer(post)
print(serializer.title)
# 'foo title'
</code></pre>

<p>I need this for fields that are added in the serializer, but are not already on the model, like if the logged in user has liked the post.</p>
