+## Overiding the URL field behavior
+
+The name of the URL field defaults to 'url'.  You can override this globally, by using the `URL_FIELD_NAME` setting.
+
+You can also override this on a per-serializer basis by using the `url_field_name` option on the serializer, like so:
+
+    class AccountSerializer(serializers.HyperlinkedModelSerializer):
+        class Meta:
+            model = Account
+            fields = ('account_url', 'account_name', 'users', 'created')
+            url_field_name = 'account_url'
+
+**Note**: The generic view implementations normally generate a `Location` header in response to successful `POST` requests.  Serializers using `url_field_name` option will not have this header automatically included by the view.  If you need to do so you will ned to also override the view's `get_success_headers()` method.
+
+You can also overide the URL field's view name and lookup field without overriding the field explicitly, by using the `view_name` and `lookup_field` options, like so:
+
+    class AccountSerializer(serializers.HyperlinkedModelSerializer):
+        class Meta:
+            model = Account
+            fields = ('account_url', 'account_name', 'users', 'created')
+            view_name = 'account_detail'
+            lookup_field='account_name'
